    INTRODUCTION TO OPERATING SYSTEM

    An operating system, or OS, is a program designed to run other programs on a computer.

    A computers operating system is its most important program. It is considered the backboneof a computer, managing both software and hardware resources. Operating systems are

    responsible for everything from the control and allocation of memory to recognizing input

    from external devices and transmitting output to computer displays. They also manage files

    on computer hard drives and control peripherals, like printers and scanners.

    The operating system of a large computer system has even more work to do. Such

    operating systems monitor different programs and users, making sure everything runs

    smoothly, without interference, despite the fact that numerous devices and programs are used

    simultaneously. An operating system also has a vital role to play in security. Its job includes

    preventing unauthorized users from accessing the computer system.

    There are few types of Operating Systems. A Multiprocessing Operating System allows a

    program to run on more than one Central Processing Unit (CPU)at a time. This can come in

    very handy in some work environments, at schools, and even for some home-computing

    situations. Multitasking Operating Systems work a little differently; they allow simultaneousexecution of multiple programs using a single processor to run more than one program at a

    time. Multiprogramming Operating Systems are even more different, allowing for more than

    one active user program to be stored in main memory simultaneously. Time Sharing

    Operating System enables multiple simultaneous users and the programs are executed bit by

    bit. Real Time Operating Systems are designed to respond within a certain period of time.

    Single User Operating System allows one user at a time to use the computer. Multi User

    Operating System allows for more than one user to use the computer simultaneously. Batch

    Operating System only does one thing at a time.

    INTRODUCTION FOR WINDOWS 7

    There are so many Operating System has been launched. Windows 7 which is very

    popular and also worlds leading operating system.Windows 7 is developed by the global

    giant Microsoft, which was released for public in October 2009. Windows 7 is simpler and

    easier to use compared to its predecessor, Windows Vista. Windows Vista cannot be

    considered as a very successful launch of Microsoft. Windows 7 has a 64-bit along with the

    availability of 32-bit support which enables the users to use almost all the latest PCs. Be it

    desktops, laptops, notebooks, or anything, Windows 7 supports them all.

    Windows 7 was launched with many new and advanced features beneficial to the users.

    The main aim was to cope up with the limitations present in the previous versions that werehighly criticised. Windows Vista consisted of a big range of user friendly features but

    unfortunately, the system failed due to ever increasing complaints and negative reviews

    coming from the press. Contrary to this, Windows 7 was developed with a focus on rectifying

    the mistakes and providing noticeable upgrade to the product line of Windows. Microsoft has

    launched six different editions of Windows 7. They are listed as Starter, Home premium,

    Professional, Ultimate, OEM, Enterprise.

    PCs with multi-core processors

    Windows 7 was designed to work with today's multi-core processors. All 32-bit versions

    of Windows 7 can support up to 32 processor cores, while 64-bit versions can support up to

    256 processor cores.

    PCs with multiple processors (CPUs)

    Commercial servers, workstations, and other high-end PCs may have more than one physical

    processor. Windows 7 Professional, Enterprise, and Ultimate allow for two physical

    processors, providing the best performance on these computers. Windows 7 Starter, Home

    Basic, and Home Premium will recognize only one physical processor.

    MEMORY MANAGEMENT COMPARISON BETWEEN

    WINDOWS7 vs Mac OS

    Boot Time and Resume from Sleep

    Figure 1: memory management comparison

    Windows 7 was hyped as bringing swifter boots to PCs, but the new OS can be just as

    molasses-slow as Vista. You'll find some Windows 7 notebooks that start up in less than 60

    seconds, but most of them hover above the one-minute mark.

    OVERALL SYSTEM PERFORMANCE

    Mac OS X Snow Leopard

    We used Geek bench, an application that measures CPU and RAM performance, to gauge our

    MacBook Pro's computing prowess. It notched a score of 3,543 in Snow Leopard, and 2,789

    when we used Boot Camp to run the program under a Windows 7 partition. In addition, the

    system copied a 4.97GB folder of mixed media at a swift rate of 21.5 MBps on our LAPTOP

    Transfer Test (19.2 MBps within Boot Camp).

    Windows 7

    Our Dell PC notched 2,586 in Geek bench, which was about 200 points below the MacBook

    Pro's Boot Camp score. It completed copying our 4.97GB folder at a decent rate of 17.8

    MBps, but this was still far slower than Apple.

    Comparison: OS X Snow Leopard proved to have superior overall system performance. It

    also ran Windows 7 smoothly in Boot Camp.

    INSTALLATION

    TYPE OF INSTALLATION

    Basically, there are 2 approaches to installing Windows 7:

    Upgrade (In-place upgrade) - This option replaces your current version of Windows

    with Windows 7, and keeps your files, settings, and programs in place on your

    computer.

    Custom ("fresh" installation) - This option replaces your current version of Windows

    with Windows 7, but doesn't preserve your files, settings, and programs. It's

    sometimes referred to as a clean installation for that reason.

    Beginning the Installation Process

    When installing on a physical computer insert your Windows 7 DVD media into your DVD

    drive and reboot your computer. If you're asked to press a key to boot from DVD or CD,

    press any key. A black window will appear momentarily while the DVD content is read.

    Note: These screenshots are taken from a Windows 7 Ultimate installation performed on a virtual machine

    running on VMware Workstation. I will be using an .ISO file mounted on the VMs CD/DVD drive.

    [OPERATING SYSTEM AICT004-3-2] January 1, 2012

    ASIA PACIFIC UNIVERSITY Page 10

    Next, a Starting Windowsscreen will appear.

    Figure 3 : Starting windows

    Note: If the Windows installation page doesn't appear and you're not asked to press a key to start from DVD or

    CD, you might have to specify that your computer uses its DVD or CD drive as the startup device.

    The Installation Process

    Windows 7 does not have a noticeable text phase of the setup process, and it will boot

    directly into the Graphical User Interface (GUI) mode.

    Figure 4 : Install Windows

    ASIA PACIFIC UNIVERSITY Page 11

    After a few moments you will see the first prompt:

    Click "Next" unless you want to change some regional settings for the installation process.

    Hebrew users should read my "Installing Hebrew on Windows 7" article.

    Figure 5 : Installing Hebrew

    Click on the "Install now" button.

    Note: If you're using the installation media to repair an existing installation of Windows 7 you should also read

    my latest article on the Windows Recovery Environment.

    Next, accept the license terms and click on "Next".

    [OPERATING SYSTEM AICT004-3-2] January 1, 2012

    ASIA PACIFIC UNIVERSITY Page 12

    Next, unless you're upgrading an existing Windows installation, press the Custom

    (Advanced) installation type button. Note that in this case, the Upgrade button is disabled

    because this specific installation if performed on a new computer without any previous

    operating system on it.

    The next phase is to pick the installation partition. Since this computer has a new hard disk

    that hasn't been formatted before, you will only have the option to create a new partition on it.

    ASIA PACIFIC UNIVERSITY Page 13

    The setup process will now begin to copy files from the installation DVD media to the hard

    disk.

    Figure 8: Installing Windows

    Process could take a while depending on the type of hardware your computer uses. In my VM

    test sample I've used for this demo, the entire process finished before I could finish writing

    the previous 3 paragraphs, so it could be pretty quick.

    The computer will reboot, and the next thing you'll see is the prompt to set the user's and

    computer's name. By default, the computer's name will be username-PC, where username is

    the username you've entered.

    Note: The user you're creating will be the only user currently available on the system. Like Vista, the built-in

    Administrator's account is disabled. Read my article on how to enable the Windows 7 Administrator's

    account article for more information.

    Click on "Next".

    Figure 9: Set up windows

    Enter the users password. Remember this password, as it will be the ONLY user on the

    system, and unless you create an additional user or enable the built-in administrator account,if you forget this password youll need to crack it to gain access to the system. The best

    option would be to choose a complex password made of at least 7 characters or more

    (something like Pssw0rd or MYpa$$w0rd). You must also enter a password hint.

    Click on Next.

    Figure 10: Setting password

    Next, type in your product key. If you do not have the product key at hand you can still click

    "Next", and proceed with the installation. You will be asked to enter the product key after

    Windows is installed.

    Choose what sort of protection your computer gets. The recommended settings are best for

    someone that doesn't plan to hide their computer behind a corporate. If you plan to install a

    3rd-party firewall later you can opt to be prompted later. Note that this setting will also have

    effect on how the computer uses the Microsoft Windows Update (Automatic Updates)

    features.

    USER INTERFACE

    A new-look user experience

    Figure 16: New look User

    One of the first things we've noticed is that Windows 7, in its default state, looks very, very

    simple. In contrast to Vista, there's no pop-up Welcome Centre, no pre-loaded Sidebar

    Gadgets and very little clutter in the system tray. Instead, you've a sole Recycle Bin on the

    desktop, and a trio of icons in the quick-launch area; Internet Explorer, Explorer and

    Windows Media Player.

    Jump Lists and Taskbar inconsistencies

    Expanding the functionality of the new-look Windows Taskbar is a feature that makes its

    debut in 7; Jump Lists.

    Essentially an expanded set of menu options, the Jump List is available by right-clicking any

    icon in the Taskbar area, including both shortcuts and open applications.

    ASIA PACIFIC UNIVERSITY Page 21

    Despite the promising introduction of new functionality, Microsoft's bold revision of the

    Taskbar isn't without its faults. During use, we've noticed a handful of shortcomings. Firstly,

    it isn't possible to pin multiple associated items separately onto the Taskbar. Secondly,

    multiple instances of an open application or window are automatically grouped together on

    the Taskbar, irrespective of whether the Taskbar is viewed with or without labels.

    Figure 20:Windows

    Take, for example, the tooltips for minimize, maximize and close. For some unknown reason,

    they appear in the old Windows XP style, with a cream-colored background and a square box

    (pictured above, right).

    Windows Aero, take two

    Aero, the graphical user interface introduced in Windows Vista, has been given a significant

    overhaul in 7. What was once seen as little more than superfluous eye-candy has been

    transformed into a tool designed to improve productivity.

    Snap it, shake it, aero flip it

    Arguably our favourite new feature in terms of everyday productivity is Aero Snap. Allowing

    multiple sources of content to be viewed side-by-side with ease, it snaps windows to the left

    or right sides of the screen and resizes them to 50 per cent of the desktop real estate.

    Figure 23 :Windows

    When used with big-screen displays, it's a feature you soon find yourself unable to live

    without. Aero Snap can be used by dragging a window to either the left or right edges, or via

    keyboard shortcuts (Windows key + left/right arrow). Similarly, dragging a window to the

    top will maximize it, whilst pulling it away will restore down. Simple, but mighty effective.

    The first thing you'll notice is that 7's Explorer is in keeping with the rest of the operating

    system; it's cleaner and looks more refined. The file menu takes on a subtle shade of blue and

    consequently almost goes. Users are free to create as many libraries as they wish, and it's a

    feature that even at this first stage looks increasingly impressive. For example, the

    Documents library can be arranged by folder, author, date modified, tag, type and name.

    Any other Advantages

    For those making use of multiple displays, a new keyboard shortcut (Windows Key + P)

    simplifies the task of switching between display modes.

    Figure 26:New Keyboard shortcuts

    Available options include computer only, duplicate (mirror), extend and projector (or external

    display) only.

    Gadgets, another feature that first debuted in Windows Vista, has also been revamped for 7.

    PROCESS CONTROL MANAGEMENT

    PROCESS

    It is a plan in killing that progress in a sequential manner. It is a constituent of work alongside

    exceptional procedure identification. It needs resources like recollection, CPU period and

    files to finish its task. The working arrangement creates and deletes user and arrangement

    processes. A running procedure can perhaps come to be Blocked, Prepared or Terminated. A

    Running procedure becomes Blocked after the procedure itself cannot present because it is

    staying for an I/O procedure to finish, or after it is staying for a little external event to

    happen.

    PROCESS CONTROL BLOCK (PCB)

    A procedure in a working arrangement is embodied by a data construction recognized as a

    procedure manipulation block (PCB) or procedure descriptor. The PCB is a precise store that

    permits to find key data concerning a process. Thus, the PCB is the data construction that

    defines a procedure to the working systems.

    ASIA PACIFIC UNIVERSITY Page 29

    PROCESS SCHEDULING

    As procedures go in the arrangement, they are locale on the job queue. A new procedure is

    locale on the prepared queue. The procedure waits till it is selected for killing (or dispatched)

    and given CPU resources. After the CPU is allocated and the procedure is running the

    procedure might subject an I/O appeal and be allocated on a mechanism queue, the procedure

    might craft a new sub-process, the procedure might be forcibly removed.

    CONCURRENT PROCESS

    Concurrent procedures can be autonomous or cooperating processes. Autonomous procedures

    are procedures that do not demand to interact alongside supplementary processes.

    Cooperating procedures are procedures that work alongside every single supplementary, and

    can alter or be altered by one more process.

    Why ought to a working arrangement permit for cooperating processes? Data allocating and

    to permit admission to resources employing the PCB. Rise computation speed.

    THREAD

    A mini handy procedure that can present independently of supplementary portions of the

    process. Two kinds of threads: user procedures and arrangement processes. Conception of a

    new procedure (child) from the older one (parent) is shouted spawning or forking.

    DEADLOCK MANAGEMENT

    Deadlock is a situation may arise in shared resources whereby two or moreprocesses (also

    called threads) cannot continue because theresources which each process requires are held by

    another process. Deadlocks prevention provides a set of methods for safeguarding that at least

    one of the vital conditions cannot hold. These methods stop deadlocks by constraining how

    demands for resources can be made. Deadlock is also divided into 4 types of conditions,

    which are mutual exclusion, hold and wait, No-preemption and circular wait.

    Resources

    Deadlocks can occur after procedures have been conceded select admission to devices, files

    and so forth. To make the discussion of deadlocks as finished as probable, we will denote to

    the objects conceded as resources. A resource can be a hardware device or a piece of

    information. Resources come in two types: Preemptable and Non-preemptable. A

    Preemptable resource is one that can be seized away from the procedure owning it alongside

    no ill effects.

    Preemptable resources

    A Preemptable resource is one that can be seized away from the procedure owning it

    alongside no ill effects.

    Memory is an example of a Preemptable resource. Consider, for example, an arrangement

    alongside 32 MB of user memory, one printer, and two 32-MB procedures that every single

    desire to print something.

    Process A appeal and gets the printer, next onset to compute the benefits to print. Before it

    has finished alongside the computation, it exceeds its period quantum and is swapped out.

    Process B nowadays runs and tires, ineffectively, to buy the printer. Potentially, we nowadays

    have a deadlock situation, because A has the printer and B has the memory, and neither can

    continue lacking the resource held by the other. Fortunately, it is probable to preempt (take

    away) the recollection from B by swapping it out and swapping A in. Nowadays A can run,

    do its creation, and next discharge the printer. No deadlock occurs.

    Non-preemptable resources

    A Non-preemptable resource, in difference is one that cannot be seized away from its present

    proprietor lacking provoking the computation to fail. An example deed in windows 7, if a

    procedure has begun to burn a CD-ROM, unexpectedly seizing the CD recorder away from it

    and providing it to one more procedure.

    Deadlock Conditions:-

    Mutual exclusion

    This condition happens after a resource that cannot be utilized by extra than one procedure ata period.

    Hold and wait

    Holding at least one procedure and will accord supplementary resources that owned by

    supplementary process.

    No-preemption

    The process that can only release the resource after the procedure has completed.

    Circular wait

    A circular wait happen if the chain of two or extra threads is staying for a resource held by

    the subsequent member in the chain. This wills automatically locale the computer into

    deadlock situation.

    Methods to handle deadlock situation:

    Deadlock Prevention

    Mutual Exclusion- allows resources to allocate among different processes that it

    allows the computer to allocate the resources.

    Hold and Wait- if the process is holding each resource next the supplementary

    resource will not allowed.

    No-Preemption- allow preemption way it allows the resource to pause till the

    procedure to end.

    Circular Wait- the system will try to allow the process present as fast as possible.

    Deadlock Avoidance

    Normally in windows7 there is a Process Control Block (PCB) that will halt the new appeal

    process as one more process is executing.

    Deadlock Detection

    Instead to allow the deadlock happen, the system will detect to notice it after it happened by

    the PCB and it will find a little supplementary methods to resolve it if the PCB does not work

    properly.

    Deadlock Recovery

    Recovery through Preemption - There is only voluntary release of a resource - nobody else

    can make a process give up a resource.

    Roll back - The process of restarting a process from a checkpoint is called rollback. The hope

    is that the resource requests will not interleave again to produce deadlock.

    Killing - The system will kill the process until the dead lock had been terminated by the

    system. Because of some of the programs are important so the system will kill the selectedprograms only.

    Figure 30:Virtual Memory

    For windows 7, virtual memory combines active RAM and inactive memory on DASD [NB

    1] to form a large range of contiguous addresses.

    In computing, virtual memory is a memory management technique developed for

    multitasking kernels. Random-access memory and disk storage, allowing a program to be

    designed as though there is only one kind of memory, "virtual" memory, which behaves like

    directly and contiguous addressable read/write memory.

    Figure 31: Virtual Address

    For windows 7, the virtual address space for a process is the set of virtual memory addresses

    that it can use. The address space for each process is private and cannot be accessed by other

    processes unless it is shared.

    A virtual address does not represent the actual physical location of an object in memory;

    instead, the system maintains a page table for each process, which is an internal data structure

    used to translate virtual addresses into their corresponding physical addresses. Each time a

    thread references an address, the system translates the virtual address to a physical address.

    The virtual address space for 32-bit Windows is 4 gigabytes (GB) in size and divided into

    two partitions: one for use by the process and the other reserved for use by the system.

    Optimal usage of system memory is a constant area of investment. The working set

    comprises all the potentially trimmable and virtual addresses for a given process, session or

    system resource.

    Task Manager

    Windows 7 Task Manager is a task manager application included with Microsoft Windows

    NT family of operating systems that provides detailed information about computer

    performance and running applications, processes and CPU usage, commit charge and

    memory information, network activity and statistics, logged-in users, and system services.

    The Task Manager can also be used to set process priorities, processor affinity, forcibly

    terminate processes, and shut down, restart, hibernate or log off from Windows 7. Windows

    Task Manager was introduced with Windows NT 4.0, previous versions of Windows NT

    included the Task List application.

    SECONDARY DISK SCHEDULING MANAGEMENT

    A hard disk drive is a collection of plates shouted platters. The external of every single platter

    is tear into circular tracks. More extra, every single trail is tear into tinier pieces shoutedsectors. Disk I/O is completed sector by sector. A cluster of tracks that are positioned on top

    of every single supplementary form a cylinder. There is a head related to an arm for every

    single external that grips all I/O operations.

    Disk Association Tool:

    Disk Association is a functional built-in Windows 7 partition manager that makes hard disk

    partitioning quick and simple. Windows 7 Disk Association includes:

    A built-in partition manager

    A graphical user interface (GUI)

    Ability to craft new disk partitions inside Windows 7

    Ability to contract continuing disk partitions

    With Disk Management, you can initialize disks, craft volumes, format volumes alongside

    file arrangements FAT, exFAT, FAT32 or NTFS. You can additionally spread a disk, cut a

    disk, check if a disk is healthy or harmful, craft partitions, delete partitions, or change a drive

    letter. Disk Association enables you to present most disk-related tasks lacking restarting the

    arrangement, and most adjustments seize result immediately.

    Disk Maintenance:

    If you want to reduce the number of unnecessary files on your hard disk to free up disk space

    and help your computer run faster, use Disk Cleanup. It removes temporary files, empties the

    Recycle Bin, and removes a variety of system files and other items that you no longer need.

    Follow these steps:

    1. Open Computer, right click on the drive you wish to clean and selectProperties.

    2. Click theDisk Cleanupbutton on the General tab and Windows will calculate how

    much space it can free up.

    3. Select the items from the list that you wish to delete and click OK.

    Figure 36: Disk Cleanup

    4. When asked Are you sure you want to permanently delete these files, clickDelete

    Files.

    As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk

    performance and sometimes make data writing (such as file saving) difficult or even

    impossible. The Error Checking utility scans the hard drive for bad sectors and scans for file

    system errors to see whether certain files or folders are misplaced. To scan a disk, follow

    these steps:

    1. Open Computer, right click on the drive you wish to check and selectProperties.

    2. Click the Toolstab and then click the Check Nowbutton.

    Fragmentation makes your hard disk do extra work that can slow down your computer.

    Removable storage devices such as USB flash drives can also become fragmented. Disk

    Defragmenter rearranges fragmented data so your disks and drives can work more efficiently.

    Disk Defragmenter runs on a schedule, but you can also 42nalyse and defragment your disks

    and drives manually. To do this, follow these steps:

    CONCLUSION

    This assignment has helped us to have a larger understanding concerning Windows 7.

    Windows 7 has a lot enhancement from the previous version. For example, the processor is

    far faster than the previous version. It provides efficiencies that aid cut the manipulation that

    associations consume after running client computers and helps users become extra existence

    out of their handy computers batteries As well that, the snipping tool that enables the user to

    screenshot selected serving that the user wanted Windows 7. The limitation that we

    confronted after acting this assignment is lack of reference resources. We demand to examine

    the manipulated resources ourselves in order to finish the assignment.
