Windows Xp


Windows:

    Windows is a computer operating system and graphical user interface (GUI), which enables us to work with a wide variety of programs on your computer, often simultaneously. Windows is itself a special computer program that communicates your instructions to the actual computer hardware, and displays the results.

OBJECTIVES:
After going through this lesson, you would be able to:

  • ·        Explain the basics of operating system
  • ·        Describe XP desktop elements
  • ·        Create file or folder in XP
  • ·        Change system settings
  • ·        Work on windows explorer


XP Desktop Elements:

Task Bar:

     When you start the computer system, then start and task bar appears on the bottom of the screen and by default remains visible when Windows is running. Whenever a program is run or a window is opened, an icon representing the program appears on the taskbar. To switch between windows or program, click on the icon representing the window on the task bar. When the program or window is closed, the icon disappears from the task bar.

Start Menu:

     When clicked on the start button, menu as follows appears on the screen giving all the available options to start using the Windows.

The Desktop:

The Desktop

    Desktop gives you access to everything you need in Windows XP. It occupies the entire screen, and unlike a window, it can’t be reduced in size. The desktop consists of a patterned background, containing small pictures called Icons that represent programs or data stores. Double-clicking on an icon opens the corresponding program or file inside a window.

The icons

    Icons are visible on your desktop depend on choices made at installation. In the UCT labs, you will usually see icons for y My Computer (the gateway to your computer’s drives, or data storage areas), Recycle Bin (a temporary “trashcan” that holds files you want to delete).

The Taskbar

     Taskbar lies across the bottom edge of your screen. The Start button on the left provides access to all the programs, data files, and other features available on your computer. When you open a program or file, a corresponding rectangular icon will be displayed on your taskbar even if the program has been minimized and is no longer visible on your screen. To access that program, you just need to click its icon on the taskbar.

The Start menu

     Start menu When you click on the Start button, a set of menu options is displayed. The contents will vary depending on your computer setup and most frequently accessed programs. If you click on the All Programs option, you’ll see a list of all the programs installed on your computer even those that don’t have icons on the desktop. Press the Esc (escape) key to close the menu.


THE CONTROL PANEL:

    In Vista this was known as the Control Panel Home view versus the Classic view. In Windows 7, this view is known as the Category view. This can be change by clicking on the right of the View by category in the upper right corner of the windows.

     The new Control Panel organizes all functions into easy to find categories If you are familiar with previous versions of Windows (XP,2000, Windows Me) and their predecessors, the “Icon View” should be easier to navigate. This is the best way to easily see all components of the Control Panel When you open your Control Panel window, you will notice the many icons that are available for adding, removing and changing.

     We have gone through many of the icons shown above, such as Add/Remove Programs, Date/Time, Display, Fonts, Mouse, Scheduled Tasks and System. Something that you might want to do is to change the sound or music that you hear when the computer speakers are on. See what you can do with the sound by opening Sounds and Audio Devices.

     As we can see, the computer can be set to your pleasure that is why it is called a PC (Personal Computer). You are now looking under the hood of Windows. In this window you can make many changes to your computer. There are some settings that you shouldn't play with until you have gain a better understanding of your machine. We will deal with options that you may want to use.

Characteristics of computers

    Characteristics:        All computers have similar characteristics, which tells how computers are efficient to perform task. Computers have some Limitations also. Speed:     Computer can work very fast. It takes only few seconds for calculations on very large amount of data. Computer can perform millions (1,000,000) of instructions per second.      We measure the speed of computer in terms of microsecond (10-6 part of a second) or nanosecond (10 to the power -9 part of a second).   Accuracy:        The degree of accuracy of computer is very high and every calculation is performed with the same accuracy.  The errors in computer are due to human and inaccurate data.       The calculation done by computer are 100% error free, If we provide accurate input. Diligence:        A computer is free from tiredness, lack of concentration...

DS LAB FOR II YEAR

1.SINGLE LINKED LIST Procedure for creation of single linked list: STEP-1 : Declaring a variable named as “item”.Ie the element what we place in the linkedlist of the new node.         STEP-2 : Read the value   in “item”. Set first=last=null and next=null. STEP-3: Create a new node named as temp and assign the variable item to data part andassign Address of the node temp to null.       temp.data=item;       temp.next=null; STEP-4: Check   the address part of the first node Check if first=null Then assign first=last=temp Other wise Then assign the new node tolast.next=temp          last=temp STEP-6 : Repeat STEP-3 until you read required nodes. Procedure for display the linked list: STEP-1 : Check whether the list having nodes or not i.e Check if first=null        ...

Block diagram of computer

    The basic architecture of computer explained in Blocks is called Block Diagram of computer. This basic architecture of computer finally given by John V on Neumann. Thus it is also called  V on Neumann  architecture. It  is a theoretical design for computer that serves as the basis for almost all modern computers. Input Unit:      We need to input (fed) the data and instructions into the computers to process any task. The input unit consists of one or more input devices.      Keyboard is the one of the most commonly used input device. Other commonly used input devices are the mouse. Output Unit:     The output unit of a computer provides the information and results of a computation to outside world.        Printers, Visual Display Unit (VDU) are the commonly used output devices.   Storage Unit:      The storage unit of the computer holds data and in...
