1. (a) Create a folder named Harper. Type the document below exactly as it appears using a word processing package and save it as MOCKING_BIRD in the folder created. (8mks)

TO KILL A MOCKINGBIRDTo Kill a Mockingbird is primarily a novel about growing up under extraordinary circumstances in the 1930s in the Soutern United States. In To Kill a Mockingbird, author Harper Lee uses memorable characters to explore civil rights and rasism in the segregated Southern United States of the 1930s.

Told through the eyes of Scout Finch, you learn about her father Atticus Finch, an attorney who hopelessly strives to prove the innocence of a black man unjustly accused of rape; and about Boo Radley, a mysterious neighbor who saves Scout and her brother Jem from being killed.

The Three Most Important Aspects Of To Kill A Mockingbird :

The title of To Kill a Mockingbird refers to the local belief, introduced early in the novel and referred to again later, that it is a sin to kill a mockingbird. Harper Lee implies that it’s unjust and immoral.

The events of To Kill a Mockingbird take place while Scout Finch, the novel’s narrator, is a young child. But the sophisticated vocabulary and sentence structure of the story indicate that Scout tells the story many years after the events described, when she has grown to adulthood.

To Kill a Mockingbird is unusual because it is both an examination of racism and a bildungsroman. Lee examines a very serious social problem. Lee seamlessly blends these two very different kinds of stories.

TOTAL SCORE

This paper consists of 4 printed pages. Candidates should check the question paper to

Ensure that all the pages are printed as indicated and no questions are missing.

1. a) Using a word processor type the passage below as it appears and save it as Society (40 marks)

16

ociety has failed and parents have not played their role fully in raising their children. This is according

to Jeff Ngari, a counseling psychologist and a deacon with the Reformed Catholic Church. Jeff says the

issue of teenage mothers is so big that it should be considered a cry for help. He adds that today’s

children, lack the guidance they require when it comes to having independent social interactions.

S“The idea is not to block them from forming

their own relationships, but to make them

understand what it means to be in a

relationship, especially with the opposite sex,

and how far this relationship should go,” says

Jeff.

And just like the rest of society, parents have

not been spared by the wave of moral decay

and thus, according to Jeff, they have failed as

role models for their children. Due to this,

many teenagers are picking up social ills from

their parents-the very people they are

supposed to look up to.

“For instance, a teenager who has seen his or her mother repeatedly sleep out or come home in the wee

hours of the morning will most likely be excited about staying out late out of curiosity, “he says, adding, “this

is happening to most of our homes today.”

Jeff says many parents

are engaging carelessly in

extra-marital

relationships that leave

very little to the

imagination of their

children, and this is likely

to be seen as a normal

thing by children,

especially teenagers.

As a result, there are

many avenues through

which teenagers can

explore the issue of sex

and the greatest worry

that girls need to be

rescued

PRE-MARITAL AND EXTRA MARITAL SEX IS DANGEROUS

17

Most teenage mothers experience rejection and abuse by their families, friends

and wider community, including the church. “No wonder these girls

abandon their babies either in toilets or litter bins. The

effects of rejection can be fatal- rejection by society is the

worst thing anybody can suffer. It kills from within. That is

why teenage motherhood is a cry for help and family

support is very important, as the result is children giving

birth to, and trying to raise babies.”

“In the course of my career, I have met mature women

who tell me they had abortions when they were very

young and they still feel guilty decades later. Some even go to the extent of saying, ‘My first-

born would be this or that age.’ It is very painful.”

In Kenya, four in every 10 women who die from unsafe abortion are adolescents; 70% of

adolescents engage in high-risk unprotected sex. This is according to a research paper

presented by Dr. Richard 0. Muga of the National Co-ordinating Agency for Population and

Development, Nairobi-Kenya, 2006.

The alarming figures are why Margaret Muyanga, a counseling psychologist, says open

communication between teenagers and parents can be very instrumental in curbing any post-

pregnancy abortion or even worse, suicidal tendencies.

1. Multiple users can communicate, exchange and share information2. Resource sharing including program, data base, hardware etc. is possible

By definition communications refers to the transfer of information from one place to another between two individuals using agreed symbols, signs or even human behavior such as nodding. Exchange of information relies on a communication system to convert, amplify and send signal through a common medium. Message, Sender, Medium and Receiver are the essential components of communication systems.

If a system is extended by cascading more communication systems, it is called networked systems.

In case communication involves the sending of information over a significant distance, it must use telecommunications as an aid. By definition, telecommunications refers to the transmission of information between distant locations by some electromagnetic means.

Data communications is defined as the interchange and processing of encoded (digital that is, 1s and 0s) information between distant locations using telecommunications.

Data communications is regarded as the collection and distribution of the electronic representation of information which can be text, voice, graphics or image, from and to remote computing facilities. As information can only be carried to the remote site provided that the information carrier supports that particular type of data transmission, information may undergo data conversion processes if the nature of data signal is incompatible with the characteristics of the signal carrier.

Communication networks are usually defined by their size and complexity. We can distinguish four main types:

Local area networks (LAN). These networks connect computer equipment and other terminals distributed in a localized area, e.g. a university campus, factory, office. The connection is usually a cable or fibre, and the extent of the cable defines the LAN.

Metropolitan area networks (MAN). These networks are used to interconnect LANs that are spread around, say, a town or city. This kind of network is a high speed network using optical fibre connections.

Wide area networks (WAN). These networks connect computers and other terminals over large distances. They often require multiple communication connections, including microwave radio links and satellite.

COMPARISON AMONG DIFFERENT TOPOLOGIES

Below are the advantages and disadvantages of various LAN topologies.

Type Advantage Disadvantage Star Simple and easy to identify fault Failure of central node causes disaster Irregular (Mesh)

Immunity to bottleneck and failure problems

Expensive to provide an alternative routing

Bus Simple to control traffic flow Only a single communications channel is required to service all the nodes

Ring Simple to implement One channel is required to service all

TRANSMISSION MEDIA

Transmission can be by cable or wireless methods. There are 3 common types of cable:

Twisted pair, Co-axial Fiber optic.

Wireless transmission includes:

Microwave transmission. Satellite transmission. Radio waves transmission. Infrared transmission.

TWISTED PAIR

•Consists of two insulated copper wires arranged in a regular spiral pattern to minimize the electromagnetic interference between adjacent pairs

•Often used at customer facilities and also over distances to carry voice as well as data communications.

TWISTED PAIR ADVANTAGES

Inexpensive and readily available Flexible and lightweight Easy to work with and install

TWISTED PAIR DISADVANTAGES

Susceptibility to interference and noise Attenuation problem For analog, repeaters needed every 5-6km For digital, repeaters needed every 2-3km Relatively low bandwidth (3000Hz)

CO-AXIAL CABLE

Used for cable television, LANs, telephony Has an inner conductor surrounded by a braided mesh Both conductors share a common center axial, hence the term “co-axial”

CO-AXIAL ADVANTAGES

Higher bandwidth

400 to 600Mhz Up to 10,800 voice conversations Can be tapped easily (pros and cons) Much less susceptible to interference than twisted pair

CO-AXIAL DISADVANTAGES

High attenuation rate makes it expensive over long distance Bulky Greater capacity (bandwidth of up to 2 Gbps) Smaller size and lighter weight Lower attenuation Immunity to environmental interference Highly secure due to tap difficulty and lack of signal radiation

FIBER OPTIC CABLE

Relatively new transmission medium used by telephone companies in place of long-distance trunk lines

Also used by private companies in implementing local data communications networks

Require a light source with injection laser diode (ILD) or light-emitting diodes (LED)

ADVANTAGES OF FIBER OPTIC

greater capacity (bandwidth of up to 2 Gbps)

smaller size and lighter weight

lower attenuation

immunity to environmental interference

highly secure due to tap difficulty and lack of signal radiation

DISADVANGES OF FIBER OPTIC

expensive over short distance

requires highly skilled installers

adding additional nodes is difficult

SYSTEMS DEVELOPMENT LIFE CYCLE

The activities that comprise systems development are encompassed in the term systems analysis and design. These stages include:Problem recognition and definition, Information gathering, Requirement specification, System design, System development, System implementation, System maintenance and review

aturally one must know, recognise and understand the problem before it can be solved. Generally, the need will pertain to the improvement of an is or a particular procedure. Problem definition follows which starts by examining whatever current information system is in use, any existing problems in the

current system and suggesting some possible plans as alternatives to the present system. NAfter approval a more detailed survey is conducted on the existing system mostly to establish its weaknesses and strengths. This is called fact-finding or fact gathering. In requirement specification the system analysts come up with the detailed requirements for the proposed system. It involves determination of user requirements e.g. Task performed, output expected, proposed system development cycle and user goals. This is the systems analysis.

System design entails the activities of transforming the requirement specifications into a logical view of the system that focuses on computer based solutions. Whereas analysis places emphasis on the problem, design places emphasis on the technical and implementation concern of the system. System development. also known as construction stage involves programming, testing, documenting and installation of the software. System Implementation And Testing Involves The Practical Work Of Transferring From The System Design Into a Working System.

An information system is dynamic and must be responsive to the changing needs of the company and those who use it. The process of modifying and adjusting an information system to meet changing needs and make it adaptive is known as system maintenance. Just like a new automobile will need some screws tightened after a few hundred miles, an information system will need some fine-tuning just after implementation. Thereafter and throughout the production stage of the system life cycle, the system will be modified many times

Question Two

a) Type the following document in a word processor and save it as Simulation (20 Marks)

Meaning

Is a method of approach to problems which involves building a model of the system to be investigated

observing the behavior of the system by gathering useful data about the model. It is therefore a “Try and see

what happens” method which is cheaper than direct experimentation using the real system. In business, the

process of experimenting with a model usually consist of inserting different input values and observing the

resulting values.

Why use simulation

Used where analytical techniques are not available or would be very complex. It is used in most

queuing systems, inventory control problems, production planning problems, corporate planning

etc.

Simulation often provide an insight into a problem which would be unobtainable by other means.

Variables in a simulation model

a) Input variables – these are grouped further into;

i) Controlled input variables

These are variables which can be controlled by management like reorder level or reorder quantity in a

stock control system.

ii) Non controlled input variables

They are variables not controlled by management like the demand of goods in a stock control system.

b) Parameters

These are input variables which have a constant value and are used to specify the relationship between

other variables.

c) Status variables

These are general circumstances of a system which may affect the output such as times or seasons. For

instance demand in a queuing system like supermarket is greatly influenced by the season of the year.

d) Output variables

These are the results of simulation. They arise from the calculations and tests performed in the model using

input variables, parameters and status variables.

The following table summarizes the types of simulation variables.

Business models

A model is any representation (physical or abstract) of a real thing, event or circumstances. In business planning, abstract or symbolic models are used and represent reality in numeric, algebraic or graphical form. Another definition for a model is an intelligent representation of reality developed to help forecast what might happen when an existing operation is enlarged or has extra demands made on it.

b) Format all the text in the document as follows;

Font – Arial

Font size – 13pts (4 Marks)

c) Apply a hanging indent style to the first paragraph and 1.5 lines for line spacing (4 Marks)

d) Insert a footnote to the word simulation (The heading) as follows;

1. Using models of real objects, events or circumstances to study their behavior (3 Marks)

e) Adjust page margins of the entire document as follows;

Left – 0.7 inches

Right – 0.5 inches

Top – 0.4 inches

Bottom - 0.4 inches

Also set the paper size to A4

f) Save the document as simulation 2. (2 Marks)

g) Move all text starting from “variables in a simulation model” to the end of the table from the current document to a new blank document, and save it as model variables. (7 Marks)

N/B: Don’t save the changes in simulation 2

h) Print simulation 2 and model variables (4 Marks)

INTRODUCTION TO COMPUTERS & OPERATING SYSTEMS

A computer is a machine or an electronic device that can solve problems by accepting data, performing certain operations on that data (processing) and presenting the results of those operations (Information) Basic characteristics that distinguish a computer from other information processing devices:-

(i) A computer is electronic – That is, all its processing operations are carried out with electrical signals(ii) A computer can store information for future reference. This is done on temporary basis with

memory circuits and permanently with storage devices such as magnetic disks and tape.(iii) A computer is programmable – unlike other devices built to perform a single function, a computer

can be instructed or programmed to perform a variety of tasks.

HOW A COMPUTER OPERATES

Converting the data (raw facts) into information (Organized, usable form) is called data processing.

Data get into the system by means of an input device e.g. keyboard then the computer performs the necessary calculations or manipulations on the data and finally the organized information is displayed by an output device e.g. a monitor.

FUNCTIONS PERFORMED BY A COMPUTER

Although computers have many applications, they can perform only three basic tasks.

(i) Arithmetic functions on numeric data (adding, subtracting, multiplying and dividing)(ii) Test relationships between data items (by comparing values)

(iii) Store and retrieve dataThese skills are really no more than people can do, but the computer can accomplish the task more;

Faster Accurately Reliably

Required:

a) Align the title to the center and underline it (1mk)b) Add border to the title. (2mks)c) Replace all the Roman numbers with bullets. (2mks)d)

i) Insert the footer “Computer Districts Mock 2008”. (2mks)ii) Insert the header “Your name and index No” (2mks)

e) Set the line spacing to exactly 1.5 (4mks)f) Insert word Art “COMPUTER” and set it to appear behind the text. (5mks)g) Search for words “Computer” and replace all with “PC”. (2mks)h) Move paragraph with the heading “how a computer operates” to the end of the document.(2mks)i) Set the font style of the document to Arial black (3mks)j) Save your work as “computer Literacy” (1mk)

k) Print your document. (2mks)

QUESTION TWO

Green Company is a company dealing with the collection and payment of tea farmers. Assuming you are working for the Company and you have been given the following data

a) Enter the data shown above into a spreadsheet giving it an appropriate title (centered) and save the workbook as Mock 1. And rename the worksheet as Entries (l0mks)

b) Copy the data to a new worksheet and enter details of farmer Mike Rua of Zone A No 147 with green leaf 4, 5632 Kg was left out insert the details in the appropriate row. (2mk)

c) Insert borders after every cell and every row. (2mks)

d) Use a function to calculate the gross pay for Farmer No 142 given that the price of green leaves is Sh.14.00 per kg (3mks)

e) Apply the formula for gross pay across the column to calculate the gross pay for all the farmers

(2mks)

f) Use a function to Calculate transport cost for all farmers given that transport is charged per Kg as follows (6mks)

Zone Price per Kg

A 1.00

B 1.50

C 2.00

g) Insert the value 20% in cell E14. Using absolute cell referencing calculate co-op deductions given that the co-op deduction is 20% of the cost. (5mks)

h) Using a formula or function calculate the net pay given that:

Net pay is Gross pay — Transport cost and co-op deductions. (4mks)

i) Format the columns containing currency values to currency with 2 decimal places and

Prefix Ksh. Rename the worksheet net pay and save it as Mock 2 (4mks)

j) Arrange the records are ascending order of the zone (2mks)

k) Use subtotals function to calculate subtotals for green leaves delivered, gross pay and net pay from each zone. (3mks)

l) Create an embedded pie chart showing the total Green leaf for each zone. The chart should have the following details in addition to other key details. Save it as Mock 3 (6mks)

a. Chart title Zone Total Green leaf for zones

Paper 2(Practical)

1. (a) Type the following passage exactly as it appears using a word processor and save it as

EXERCISE (20marks)

PROCESS OF INFORMATION SYSTEM DEVELOPMENTINTRODUCTION TO INFORMATION SYSTEM DEVELOPMENT The methodology area can justly be described as a jungle. Firstly there appears to exist many hundreds of the system development methodologies. Longworth (1985) in a recent study identified over 300. If all these are different, then it is no wonder that there is so much confusion. However, it may be that the differences are trivial and are made solely to differentiate methodologies in the market place.

WHAT IS A METHODOLOGY? The term methodology is not well defined either in Literature or by practitioners. There

is very little agreement as to what it means other than at a general level. The term is usually used very loosely and yet it is used very extensively. This loose use does not mean that there are no definitions, simply that there are no universally agreed definitions. At the general level, it is regarded as a recommended series of steps and procedures to be followed in the course and developing an information system. In a brief adhoc survey, this proves to be about the maximum that people will agree to and of course such a definition raises many more questions than it answers. For example: - What is the difference between a methodology and a method? - Does a methodology include a specification of the techniques and tools which are to be used? - Does a collection of techniques and tools constitute a methodology? - Should the use of a methodology produce the same results each time?

The questions that arise are fundamental as well as numerous. Unfortunately the most that can be achieved is to air the issues. The information system community is in the process of debating the meaning of the term methodology in an information system context, and it may one day have a universal definition. However, it may be more realistic to assume that this will never be achieved. An information system’s methodology has been defined as a recommended collection of philosophies, phase, procedures, rules, techniques, tools, documentation, management and training for developers of information systems. (Madison 1983). According to this definition, a methodology has a number of components. Which specify: (i) How a project is to be broken down into stages

(ii) What tasks are to be carried out at each stage

QUESTION TWO

2. (A) Type the following passage using a word processing package and save as Networking. Answer the questions that follow.

(31 marks)

COMPUTER NETWORK

A Computer network is a group of computers and other devices connected together by a suitable media.

Advantages of computer Networks

3. Multiple users can communicate, exchange and share information4. Resource sharing including program, data base, hardware etc. is possible

By definition communications refers to the transfer of information from one place to another between two individuals using agreed symbols, signs or even human behavior such as nodding. Exchange of information relies on a communication system to convert, amplify and send signal through a common medium. Message, Sender, Medium and Receiver are the essential components of communication systems.

If a system is extended by cascading more communication systems, it is called networked systems.

In case communication involves the sending of information over a significant distance, it must use telecommunications as an aid. By definition, telecommunications refers to the transmission of information between distant locations by some electromagnetic means.

Data communications is defined as the interchange and processing of encoded (digital that is, 1s and 0s) information between distant locations using telecommunications.

Data communications is regarded as the collection and distribution of the electronic representation of information which can be text, voice, graphics or image, from and to remote computing facilities. As information can only be carried to the remote site provided that the information carrier supports that particular type of data transmission, information may undergo data conversion processes if the nature of data signal is incompatible with the characteristics of the signal carrier.

Communication networks are usually defined by their size and complexity. We can distinguish four main types:

Local area networks (LAN). These networks connect computer equipment and other terminals distributed in a localized area, e.g. a university campus, factory, office. The connection is usually a cable or fibre, and the extent of the cable defines the LAN.

Metropolitan area networks (MAN). These networks are used to interconnect LANs that are spread around, say, a town or city. This kind of network is a high speed network using optical fibre connections.

Wide area networks (WAN). These networks connect computers and other terminals over large distances. They often require multiple communication connections, including microwave radio links and satellite.

COMPARISON AMONG DIFFERENT TOPOLOGIES

Below are the advantages and disadvantages of various LAN topologies.

Type Advantage Disadvantage Star Simple and easy to identify fault Failure of central node causes disaster Irregular (Mesh)

Immunity to bottleneck and failure problems

Expensive to provide an alternative routing

Bus Simple to control traffic flow Only a single communications channel is required to service all the nodes

Ring Simple to implement One channel is required to service all

TRANSMISSION MEDIA

Transmission can be by cable or wireless methods. There are 3 common types of cable:

Twisted pair, Co-axial Fiber optic.

Wireless transmission includes:

Microwave transmission. Satellite transmission. Radio waves transmission. Infrared transmission.

TWISTED PAIR

•Consists of two insulated copper wires arranged in a regular spiral pattern to minimize the electromagnetic interference between adjacent pairs

•Often used at customer facilities and also over distances to carry voice as well as data communications.

TWISTED PAIR ADVANTAGES

Inexpensive and readily available Flexible and lightweight Easy to work with and install

TWISTED PAIR DISADVANTAGES

Susceptibility to interference and noise Attenuation problem For analog, repeaters needed every 5-6km For digital, repeaters needed every 2-3km Relatively low bandwidth (3000Hz)

CO-AXIAL CABLE

Used for cable television, LANs, telephony Has an inner conductor surrounded by a braided mesh Both conductors share a common center axial, hence the term “co-axial”

CO-AXIAL ADVANTAGES

Higher bandwidth

400 to 600Mhz Up to 10,800 voice conversations Can be tapped easily (pros and cons) Much less susceptible to interference than twisted pair

CO-AXIAL DISADVANTAGES

High attenuation rate makes it expensive over long distance Bulky Greater capacity (bandwidth of up to 2 Gbps) Smaller size and lighter weight Lower attenuation Immunity to environmental interference Highly secure due to tap difficulty and lack of signal radiation

FIBER OPTIC CABLE

Relatively new transmission medium used by telephone companies in place of long-distance trunk lines

Also used by private companies in implementing local data communications networks

Require a light source with injection laser diode (ILD) or light-emitting diodes (LED)

ADVANTAGES OF FIBER OPTIC

greater capacity (bandwidth of up to 2 Gbps)

smaller size and lighter weight

lower attenuation

immunity to environmental interference

highly secure due to tap difficulty and lack of signal radiation

DISADVANGES OF FIBER OPTIC

expensive over short distance

requires highly skilled installers

adding additional nodes is difficult

(B) Required:

vi. Centre and double underline the title Computer Network (3 marks)vii. Convert the paragraphs Under Communications. Into hanging indent. (6 marks)

viii. Insert your name into the passage as a footer so as to appear © your name. (4 marks)

ix. Convert the paragraph under Classification of communication networks to two columns and justify them. (4 marks)

INTRODUTION TO COMPUTERS & OPERATING SYSTEMS

A computer is a machine or an electronic device that can solve problems by accepting data, performing certain operations on that data (processing) and presenting the results of those operations (Information) Basic characteristics that distinguish a computer from other information processing devices:-

(i) A computer is electronic – That is, all its processing operations are carried out with electrical signals

(ii) A computer can store information for future reference. This is done on temporary basis with memory circuits and permanently with storage devices such as magnetic disks and tape.

(iii) A computer is programmable – unlike other devices built to perform a single function, a computer can be instructed or programmed to perform a variety of tasks.

HOW A COMPUTER OPERATES

Converting the data (raw facts) into information (Organized, usable form) is called data processing.

Data get into the system by means of an input device. e.g keyboard then the computer performs the necessary calculations or manipulations on the data and finally the organized information is displayed by an output device e.g a monitor.

FUNCTIONS PERFORMED BY A COMPUTER

Although computers have many applications, they can perform only three basic tasks.

(iv) Arithmetic functions on numeric data (adding, substracting, multiplying and dividing)(v) Test relationships between data items (by comparing values)

(vi) Store and retrieve dataThese skills are really no more than people can do, but the computer can accomplish the task more;

Faster Accurately Reliably

1. A (i) Using a word processor, type the following passages as one document and save it as MIXED. (22 marks)

PRELIMINARIES

Algorithms may be quite complex. The computer programs implementing the more complex algorithms can be more easily understood if these programs are organized into hierarchies of modules. In such an organization, each program contains first a main module which gives a general description of the algorithm. This main module refers to certain submodules which contain more detailed information than the main module. Each of the submodules may refer to more detailed modules and so on. The organisation of a program into such a hierarchy of modules normally requires the use of certain basic flow patterns and logical structures which are usually associated with the notion of structured programming.

RATE OF GROWTH

Suppose M is an algorithm and suppose n is the size of the input data. Clearly the complexity f(n) of M increases as n increases. It is usually the increase of f(n) that we want to examine. This is usually done by comparing f(n) with some standard functions. The rate of growth for these standard functions give their approximate values for certain values of n. Observe that the function logn to base 2 grows most slowly, the exponential function 2 raised to n grows most rapidly and the polynomial function n to the power of c grows according to the exponent c.

1. (a) Type the following passage exactly as it appears using a word processor and save it as A:EXAMDOC1. (24 marks)

INFORMATION SYSTEM DEVELOPMENT

THE METHODOLOGY JUNGLE

The methodology area can justly be described as a jungle. Firstly there appears to exist many hundreds of the system development methodologies. Longworth (1985) in a recent study identified over 300. If all these are different, then it is no wonder that there is so much confusion. However, it may be that the differences are trivial and are made solely to differentiate methodologies in the market place.

WHAT IS A METHODOLOGY?

The term methodology is not well defined either in Literature or by practitioners. There is very little agreement as to what it means other than at a general level. The term is usually used very loosely and yet it is used very extensively.

This loose use does not mean that there are no definitions, simply that there are no universally agreed definitions. At the general level, it is regarded as a recommended series of steps and procedures to be followed in the course of developing an information system. In a brief ad hoc survey, this proves to be about the maximum that people will agree to and of course such a definition raises many more questions than it answers.

For example:

What is the difference between a methodology and a method? Does a methodology include a specification of the techniques and tools which are to be

used? Does a collection of techniques and tools constitute a methodology? Should the use of a methodology produce the same results each time?

The questions that arise are fundamental as well as numerous. Unfortunately the most that can be achieved is to air the issues. The information system community is in the process of debating the meaning of the term methodology in an information system context, and it may one day have a universal definition. However, it may be more realistic to assume that this will never be achieved. An information system’s methodology has been defined as a recommended collection of philosophies, phase, procedures, rules, techniques, tools, documentation, management and training for developers of information systems. (Maddison 1983).

According to this definition, a methodology has a number of components.

Which specify:

(i) how a project is to be broken down into stages(ii) what tasks are to be carried out at each stage(iii) what outputs are to be produced(iv) when they are to be carried out(v) what constraints are applied(vi) what support tools may be utilized.In addition, the methodology is supposed to specify how the project is to be managed and controlled and support the training needs of the users of the methodology. This is all encompassed in a view or philosophy concerning the important and critical aspects of information systems development.

(b) Remove the underline from all the underlined text and change the text to bold and italics. Save the document as A:EXAMDOC2. (8 marks)

(c) Select the text starting from the words “For example: ………. information systems development” (at the end of the passage) and move it to a new document and save as A:EXAMDOC3. (8 marks)

(d) (i) Retrieve A:EXAMDOC1 and convert it to two columns of the same width and height

(ii) Double space the first paragraph of the passage and fit the entire passage into one page. Save the document as A:EXAMDOC4. (10 marks)

(e) Print A:EXAMDOC1, A:EXAMDOC2, A:EXAMDOC3, and A:EXAMDOC4.

2. XYZ industries is a match manufacturing industry that has been in operation for the last ten years and has so far been producing three different brands of matches, Simba, Chui and Twiga. To produce a match requires two types of raw materials. The first one is available locally and the

second has to be imported. Due to the fact that some raw material has to be imported, the production is often affected by the fluctuation in the dollar rates.Table 1 shows the production details per carton.

1. (A) Type the following passage using a word processing package and save it as Recur_1. Answer the questions that follow. Where necessary, use the numbering facility in the package.

RECURSION

An object is said to be recursive if it partially consists (or is defined in terms) of itself. Recursion is encountered not only in mathematics, but also in daily life. Who hasn’t seen an advertising picture which contains itself?

Recursion is a particularly powerful means in mathematical definitions. A few familiar examples are those of natural numbers, tree structures and of certain functions.

(a) Natural numbers:

(i) 1 is a natural number.

(ii) the successor of a natural number is a natural number.(b) Tree structures:

(i) O is a tree (called the empty tree).

(ii) If t1 and t2 are trees, then the following diagram is a tree drawn upside down.

(c) The factorial function n! (for non-negative integers).

(i) 0! =1.

(ii) If n > 0, then n! = n.(n - 1)!.

The power of recursion evidently lies in the possibility of defining an infinite set of objects by a finite statement. In the same manner, an infinite number of computations can be described by a finite recursive program, even if this program contains no explicit repetitions. Recursive algorithms, however are primarily appropriate when the problem to be solved or the function to be computed or the data structure to be processed are already defined in recursive terms. In general, a recursive program can be expressed as a composition Q of base statements Si (not containing P and P itself)

P ≡ Q [Si, P].

The necessary and sufficient tool for expressing programs recursively is the procedure or subroutine for it allows a statement to be given a name by which this statement may be invoked.

O

(B) Required to:

(i) Centre and double underline the title. (3 marks)

(ii) Convert the 3rd paragraph starting from “The power of recursive … and P itself” to two columns, and justify them. (6 marks)

(v) Save the document as Recur_2. (1 mark)

(vi) Print the documents Recur_1 and Recur_2. (1 mark)
