A computer has become a necessity In modern times due to the following reasons.
(1) To save time and to tmprove performance.
(2) To avold errors/mistakes.

In DOS. pressing the Print Screen key causes the computer to send whatever Images and text are currently on the display screen to the printer Some graphics programs and Windows, use the Print Screen key to obtain Screen Captures.
Tab Key: This key can be used to move forward through options dialog box. Ctrl+Shift + Tab can be used to move backward through the options Ctrl +Tab allows movement from one open window to the next in an application with more than one open window Alt + Tab displays a list of open application windows. Keeping Alt depressed and selecting Tab cycles through the Iist. Releasing selects the highlighted application window.
Caps Lock Key: Locks the keyboard in Capitals mode (only applies to Alpha keys). The Caps Lock key should be used with caution. Using ALL CAPS Is a usability no-no as many have difmculty scanning text that is ALL CAPS. Also, when sending email in all caps, this could be misconstrued as shouting at someone.
Shift Key: The obvious use of this key is to allow selection of capttal letters when depressing characters, or selecting the characters above other non-alpha keys Depressing the Shift key while inserting a CD-ROM will bypass auto play Shit + Delete to permanently delete a selected item, bypasses the Recycle Bin.

It usually has Two or three buttons ustng which the user can select options from the screen. A most commonly use Mouse picture see below.
3. Processor (CPU) Sanl Bat A Central Processing Unit (CPU).or processor. ts the control centre for a computer. it gudes directs and governs tts performance. It is the brain of the compater. Along with Primary Storage and Input/Output facilitles the CPU has two components which are responsle for different functions These two components are iIts Control Unit (CU) and Arlthmetic Loge Unit (ALU).
Basically there are two typical components of CPU are:
6. ALU
7. CU
Arithmetic Logic Unit (ALU) - The ALU performs all four arithmetical (+,-,*,/) and some logical (<,>, <=,>=, <>) operations When two numbers are requtred to be added, these numbers are sent from memory to ALU where addition takes place and the result ts put back in the memory. The same way other Arithmetic operations are performed.
For logical operations also, the numbers to be compared are sent from memory to AlU where the compartson takes place and the result is returned to memory. The result of a lagcal operations is elther TRUE or FALSE.
Control Unit - This controls the flow and manipulation of data and Iinformation. It also controls the owd to memory and from memory to output devices Memory is also bastc part of CPU. Description of the memory is gving further in detail tn the section of Storage Devices.
