The presentation discusses the fundamentals of computers, including definitions, types (supercomputers, mainframes, mini-computers, and personal computers), and their components (hardware and software). It outlines key hardware parts like input devices, output devices, and storage devices, as well as the role of software in executing tasks. Additionally, it touches on computer networks and network topology, emphasizing the interconnection of devices for data communication.

4. Computer is automatic problem solving
machine whose main purpose is data
processing or processing information and
which is represent electrically.

5. •Supercomputers...are used to process very
large amounts of information including
processing information to predict hurricanes,
satellite images and navigation, and process
military war scenarios.
•Mainframes...are used by government and
businesses to process very large amounts of
information.
•Mini-Computers...they are used by business
and government to process large amounts of
information.
•Personal Computers 12/23/2018 5
Types of Computer

6.  Personal Computers...also known as
PC’s...are smaller and less powerful than
the others. They are used in homes,
schools, and small businesses.

Personal Computer
There are 3 main types of PCs
Desktop
Portable (Notebook/Laptop)
Hand-Held

Parts of Computer
There are two basic parts that make up
a computer...
Hardwar
e
Software

8. •Hardware is basically anything that you can
touch with your fingers. Example: Computer
Case, CPU (central processing unit), Monitor,
Keyboard & Mouse

Hardware
There are three types of hardware --
1. Input Devices
2. Output Devices
3. Storage Devices

Input Devices
Input devices used to put data into the
computer.• Keyboard
• Mouse
• Trackball
• Touch Pad
• Light Pen
• Laser
Scanner
• Pointing
Stick
• Touch
Screen
• Scanner
Keyboard Mouse
Touch PadScanner

Output basically means getting data out of the
computer.
Output Devices
Monitor Printer Speakers
Modem Fax
Headphones

12. 12/23/2018 12
Storage devices are both input and output
devices in one. A storage device is a place to
keep data that can be used later time when
needed.
Storage Devices
Some example are given
below,
Hard Disk
Floppy Disk
CD’s, DVD’s
Magnetic Tape
Flash Memory, Jump Drive

 Software is the programs and applications
that tell the computer what to do and how
to look.
 Computer programmers write the
codes/instructions that make-up software
applications/programs.
Software
There are two main types of
software,
 Operating System Software Application Software

15. 12/23/2018 15
Computer Network
It is the interconnection of multiple devices,
generally termed as Hosts connected using
multiple paths for the purpose of
sending/receiving data or media.
There are also multiple devices or mediums
which helps in the communication between
two different devices which are known
as Network devices.
Example: Router, Switch, Hub, Bridge.

16. 12/23/2018 16
The layout pattern using which devices are
interconnected is called as network topology.
Such as Bus, Star, Tree, Ring, Chain etc.
Network Topology
