What I Need to Know

This module was designed and written with you in mind. It is here

to effectively understand and apply the concept of computer, its type and

parts in installing and configuring computer systems (ICCS). The scope of

this module permits it to be used in many different learning situations.

The language used recognizes the diverse vocabulary level of students.

The lessons are arranged to follow the standard sequence of the course.

But the order in which you read them can be changed to correspond with

the textbook you are now using.

After going through this module, you are expected to:

1. Distinguish the types of computers; and

2. Identify the parts of a desktop computer.

4

What’s In

In your whole life, have you encountered/experienced using the different types of computer?

Have you tried to see or experience the supercomputers? What are the types of computers?

This lesson deals with the types and parts of computers in installing and configuring computer systems under the core competencies.

What’s New

ACTIVITY 1: Have you experience using the different types of

computer? If yes, in your notebook, write one experience and compare in terms of specifications, performance, etc. (any type of computer). Make a table of your preference on how to do it. Name it as QIII_M1_Activity 1.

Lesson 1

Types and Parts of Computer

5

What is It

Read and understand the types and parts of computers in

installing and configuring computer systems. Your understanding on these will help you deeply understand the varied types of computers and its parts in Computer Systems Servicing.

Types of Computers

Supercomputer – the biggest and most expensive type of computer, which can process trillions of instructions per second. Supercomputers are at the frontline in terms of processing capabilities. They are mainly used in scientific engineering computations. (e.g. IBM Supercomputer Blue Gene/P at Argone National Library)

Mainframe computer – the second biggest type of computer. Mainframe computers have the capacity to process millions of instructions in seconds and are capable of retrieving billions of data. Unlike supercomputers, mainframes are usually used for transaction processing.(e.g. IBM System z9 Mainframe Computer)

Minicomputer – possesses most of the features and capabilities of a mainframe computer but is smaller in size and processing capability. It accomplishes slightly less in work and has lower performance than a mainframe computer.(e.g. PDP-7 Minicomputer)

6

Personal Computer (PC) – a very common type of computer that is affordable for most computer users. Other names for this are desktop computers and microcomputers. (e.g. Dell G5)

Mobile devices (laptops, tablets, smartphones) – Mobile devices such as tablets and smartphones possess lower performance and processing capabilities than microcomputers, while many laptops possess processing capabilities that can match even top-of-the-line PCs and microcomputers. (e.g. Dell XPS Tower)

Parts of Desktop Computer

System Unit – the main part of the computer. It is an enclosure that contains the major parts or components of a computer.

Chassis/System Case – the enclosure that houses the CPU and other interior components of a computer. Normally it has expansion slots, spare drive bays, and enough space for other components and expansion cards.

Motherboard – the main printed circuit board which holds the components of a computer. It supplies power and provides ways for the components to communicate with each other.

7

Central Processing Unit (CPU) – a device that handles and executes all the data and instructions that the computer receives. Also known as the brain of the computer.

Memory Module/Board – a device that allows computers to store and retain information. It is installed into a dedicated slot on the motherboard, which has varying specifications, and is therefore motherboard dependent.

Hard Disk Drives – storage devices that hold the operating system and data files. An HDD has read/write heads attached to a mechanical arm that moves around a storage platter.

Floppy Disk Drives (FDD) – a device that reads and writes information on an outdated storage device called the floppy disk, which has only 1.44MB worth of storage space.

Optical Disk Drives (DVD/CD/BD-ROM) – a device that reads and writes information on compact discs (CD), digital versatile discs (DVD) and Blu-ray discs.

8

Video Cable Connectors

Video Graphics Array (VGA) – a 15-pin D-subminiature connector first introduced in 1987 with the IBM PS/2 line of computers. It is the most common video cable connector.

Digital Visual Interface (DVI) – developed by the Digital Display Working Group (DWWG), this interface is used to connect display devices, such as projectors and monitors, to a video source such as video graphics adapter.

High-Definition Multimedia Interface (HDMI) – an audio and video interface that transfers video and digital audio data from HDMI-compliant video source devices

such as a modem/high-end graphics card device.

Power Supply Unit (PSU) – a device that converts AC power from the electrical socket to the appropriate power before distributing it to the system components via power

cables.

9

Cooling Fan – a temperature-regulating device that disperses excess heat inside the system unit to maintain the ideal temperature necessary for the components to yield optimal output or performance.

CPU Heat Sink – temperature regulators that are specific to CPUs and processors that are prone to heating due to their high processing speeds. Heat from the processor transfers and dissipates into the heat sink.

Internal Speaker – the built-in sound output device that produces beeps to tell the user if the computer has encountered an error.

Video/Graphics Card – device that converts data from the system unit to render an image or display on your monitor. Some motherboards may have built-in video adapters which should be enough for most users.

10

Sound Card – an expansion card that converts data into sound, which will then be sent to speakers. It also converts sound into digital formats. Recent motherboards have built-in sound adapters that is no need to install.

Network Interface Card – also called network card, this is an expansion card that allows a computer to connect to the Internet or to a local area network via a LAN cable or a Wi-Fi antenna.

Modem Card – enables the computer to connect to the Internet using a telephone cable.

Ports – an interface on a computer to which another computer or other peripheral devices can be connected.

Peripheral Devices – auxiliary devices that communicate with the system unit of a computer. Mouse devices, keyboards, image scanners, and other input devices are considered peripheral devices. Output devices like monitors, printers and speakers are also peripheral devices.
