 What is components of computer?
 The periferial parts of the computer which can be connected or can connect to
the computer to perform some operation or to do some basic function.
 For example:
 Mouse
 Keyboard
 C.P.U

 Components of computer are divided into two main parts :
I. Hardware :
 Computer hardware is the collection of physical parts of a computer system.
 This includes the computer case, monitor, keyboard, and mouse.
 It also includes all the parts inside the computer case, such as the hard disk
drive, motherboard, video card, and many others. Computer hardware which
you can physically touch.
 EX:- Monitor
Keyboard
Mouse. etc

ii. Software: It is a collection of instruction that enable the user to interact with
a computer. Without software, most computers would be useless. For example,
without your Internet browser software, you could not surf the Internet or read this
page. Without an operating system, the browser could not run on your computer. The
picture to the right shows a Microsoft Excel box, an example of a spreadsheet software
program.
 Example:
 Antivirus
 Programming language
 Presentation. etc

 What is central processing unit (CPU)?
 CPU is known as Central processing unit. It is the unit which performs most of the processing
inside a computer.
 It is also called as microprocessor or processor. It is the brain that runs the show inside the
Computer.
 CPU consist of transistors, that receives inputs and produces output. Transistors perform logical
operations which is called processing.

 Parts of Central processing unit (CPU):
 Arithmetic Logic Unit (ALU):
 It is the part of computer processor (CPU) used to perform arithmetic
and logic operations.
 The Arithmetic and Logic Unit which performs all the arithmetic and
logical operations such as addition, subtraction, etc.

9. COMPONENTS OF COMPUTER, CPU 9
 Control Unit (CU):
 A control unit (CU) handles all processor control signals.
 It directs all input and output flow, fetches code for instructions from microprograms
and directs other units and models by providing control and timing signals.
 A CU component is considered the processor brain because it issues orders to just
about everything and ensures correct instruction execution.

10. COMPONENTS OF COMPUTER, CPU 10
 Memory Units (MU):
 A memory is just like a human brain. The computer memory is a temporary storage
area.
 It holds the data and instructions that the Central Processing Unit (CPU) needs. Before
a program can be run, the program is loaded from some storage medium into the
memory.
 This allows the CPU direct access to the program. Memory is needed in all computers.

11. COMPONENTS OF COMPUTER, CPU 11
Conclusion:
 Thus from these presentation I got to know about
components of computer system.
 Different between Hardware and Software.
 Detail about central processing units (CPU).
