A computer system consists of both hardware and software. The hardware are the physical components of the computer like the input devices, output devices, and system unit. The system unit contains the central processing unit and other internal components. Software includes the programs and data used on the computer, and there are two main types - systems software that manages the computer's resources, and application software that allows users to perform tasks. A computer receives data as input, processes it according to programmed instructions, and produces output.

SOFTWARE AND HARDWARE

3. Computer
Systems
• A computer is an electronic device
that receives data as input,
processes it in accordance with a
set of rules, and then generates a
product known as output.
• In today's society, a computer
system is essential for any kind of
demand.
• A computer system is a machine
that can carry out various logical
and mathematical processes and
can be customized to meet specific
needs.

4. Hardware
• Hardware is the physical
components of the computer that
we can we can touch.
• Hardware components are divided
into
-Input devices
-Output devices
-System unit

5. More on
Hardware
• Examples of Input devices are
keyboard, mouse, joystick,
scanner microphone etc
• Examples of Output devices are
printer, monitor, speaker,
headphones, web cam etc
• Examples of System Unit are
CPU, Power supply, hard disk
drive, modem, video card,
sound card etc

7. Software
• Software is the term we use for
all the programs and data that
we use with a computer system.
• Two types of software
-Program is the instructions that
the computer follows
-Data is what the programs process

8. More on software
• It has two types of programs
-Systems Software is a program
designed to organize the
computer and manage
memory. For example:
operating Systems
-Application Software is a
program designed to carry out
manual tasks. For example:
Word processors and
Spreadsheet
