Components Of A Computer System
BASIC COMPONENTS OF COMPUTER SYSTEM:
here is the representation of basic components of any computer system:
COMPUTER SYSTEM
A system is a group of related components that make up a body to perform a specific
function. Therefore, computer system is defined as:
“The computer along with various units and software
that perform different activities in data processing
is collectively known as computer system”
PARTS OF COMPUTER SYSTEM
Any computer system can be divided into two basic components:
1. Hardware Components
2. Software Components
HARDWARE COMPONENTS
Computer Hardware can be defined as:
“Electronic and mechanical devices that make up the computer
are called the hardware”
Computer hardware refers to all the physical, tangible components related to computers.
We can say that the “computer hardware”
is the structural study of computers. All the
physical items like Printers, Monitors, Keyboard, Mouse, Disks, Chips and Circuits etc. are
included in the computer hardware.
“The physical and permanent components
of a computer are called hardware”
So, hardware components are the physical and tangible parts of computer system without
which computer system can not be complete.
TYPES OF HARDWARE
Hardware can be divided into three basic types:
1. Input/output devices
2. Central Processing Unit (CPU)
3. Memory
SOFTWARE COMPONENTS
“A set of electronic instructions consisting of complex codes, or
programs, that makes up the computer are called the software”
Computer software refers to the instructions to operate the hardware.
We can say that
“computer software” is the functional study of computers. Computer software includes
applications and programs like Word processor, Spreadsheets, Databases, Graphical
programs, Multimedia programs etc. So, softwares are the non-physical and in-tangible
parts of computer system without which computer system can not be complete.
TYPES OF SOFTWARE
Software can be divided into two basic types:
1. System Software
2. Application Software
