The document provides an overview of computer hardware, software, and networking, detailing components like CPUs, monitors, and input devices, as well as describing the functionality of various computer types, such as microcomputers, minicomputers, and supercomputers. It also explains the significance of input/output operations and the roles of systems and application software in operating computers. Additionally, it touches on the importance of the operating system and the distinction between command line and graphical user interfaces.

3. • Computer hardware is made up of the
equipment used to make up you computer
unit. These parts include your monitor,
central processing unit (CPU), keyboard,
mouse, printer, and modem. The computer is
an electronic machine that performs the
following four general operations: Input.

4. MONITOR
MOUSE
KEYBOARD
CPU
Computer is an electronic
device that is designed to
work with Information. The
term computer is derived
from the Latin
term ‘computer’, this
means
to calculate or programma
ble machine. Computer
can not do anything
without a Program. It
represents the decimal

5. Computer Organization

8. Computers are used daily in
schools, hospitals, banks,
government offices and many other
businesses. In addition, individuals
use computers daily to
communicate by means of social
media.

17. A supercomputer is a computer
that performs at or near the
currently highest operational rate
for computers. Traditionally,
supercomputers have been used
for scientific and engineering
applications that must handle
very large databases or do a great
amount of computation (or
both). Although advances
like multi-core
processors and GPGPUs (general-
purpose graphics processing
units) have enabled powerful
machines for personal use

18. A data processing system employed
mainly in large organizations for
various applications, including bulk
data processing, process control,
industry and consumer statistics,
enterprise resource planning, and
financial transaction processing.
Mainframes use proprietary operating
systems, most of which are based on
Unix, and a growing number on Linux.
Over the years they have evolved
from being room-sized to networked
configurations of workstations and
servers that are an extremely

19. A minicomputer fills the space
between the mainframe and
microcomputer, and is smaller
than the former but larger than
the latter. Minicomputers are
mainly used as small or
midrange servers operating
business and scientific
applications. However, the use of
the term minicomputer has
diminished and has merged with
servers.

20. A microcomputer is a complete computer on a
smaller scale and is generally a synonym for the
more common term, personal computer or PC , a
computer designed for an individual. A
microcomputer contains a microprocessor (a
central processing unit on
a microchip ), memory in the form of read-only
memory and random access
memory , I/O ports and a bus
or system of interconnecting
wires, housed in a unit that is
usually called a motherboard .

21. Our computers are on a network here at school...Look
under the table and see the blue wires that connect
your computer to the network.
The computers are connected together using copper
phone wires, fiber optic cables, or radio waves.
The internet is many networks around the world that
are all connected together to make 1 huge network.
A network is a group of computers that share
information and hardware.

24. Computer hardware is made up of the
equipment used to make up you computer
unit. These parts include your monitor, central
processing unit (CPU), keyboard, mouse,
printer, and modem. The computer is an
electronic machine that performs the
following four general operations:
Input
Storage
Control Processing Unit
Output.

25. this is the process of entering data and
programs into the computer system.
The primary devices used are the keyboard and
mouse.
Keyboard - The keyboard looks like the typewriter.
A numeric keypad is located to the right of the
keyboard. Numeric keys have the same placement as a
10-key calculator, which allow the operator to enter
data rapidly.
Mouse - A computer mouse is an input device that is most often used
with a personal computer. Moving a mouse along
a flat surface can move the on-screen cursor to
different items on the screen. Items can be
moved or selected by pressing the mouse buttons
(called clicking).

26. MOUSE

27. KEYBOARD

28. INPUT DEVICES

29. Storage devices are both input and
output devices in one. A storage device
is a place to keep data that has been
processed so that it can be retrieved at a
later time to be used again.
Hard Disk
Floppy Disk
CD’s, DVD’s
Magnetic Tape
Flash Memory, Jump Drive

31. The process of input, output, processing and
storage is performed under the supervision of a
unit called 'Central Unit'. It decides when to
start receiving data, when to stop it, where to
store data, etc. It takes care of step -by-step
processing of all operations in side the
computer.

32. Processing Unit

33. This is the process of producing results from
the data for getting useful information. The
ALU and the CU of a computer system are
jointly known as the central processing unit
(CPU). You may call CPU as the brain of any
computer system.
Example: Visual Dis play Unit (VDU), Printer,
Plotter, Floppy Disk Drive, Magnetic Disk Drive,
Speaker, Pen Drive, etc.

34. OUTPUT DEVICES

35. 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.
HTML is a type of computer programming
language that allows programmers to make web
pages.
The next 2 slides show what HTML codes look like
and the web page the codes produce.

37. 1.APPLICATION SOFTWARE
2.SYSTEM SOFTWARE

38. Application software is a program or group of
programs designed for end users. These programs are
divided into two classes: system software and
application software. While system software consists
of low-level programs that interact with computers at
a basic level, application software resides above
system software and includes database programs,
word processors, spreadsheets, etc. Application
software may be grouped along with system software
or published alone.
Application software may simply be referred to as an
application.

40.  Application Suite: Has multiple applications bundled together.
Related functions, features and user interfaces interact with each
other.
 Enterprise Software: Addresses an organization's needs and data
flow in a huge distributed environment.
 Enterprise Infrastructure Software: Provides capabilities required
to support enterprise software systems.
 Information Worker Software: Addresses individual needs required
to manage and create information for individual projects within
departments.
 Content Access Software: Used to access contents and addresses a
desire for published digital content and entertainment.
 Educational Software: Holds contents adopted for use by students.
 Media Development Software: Addresses individual needs to
generate and print electronic media for others to consume.

41. Systems software includes the programs that are
dedicated to managing the computer itself, such as
the operating system, file management utilities, and
disk operating system (or DOS). The operating system
manages the computer hardware resources in addition
to applications and data. Without systems software
installed in our computers we would have to type the
instructions for everything we wanted the computer to
do!

42. Examples would be:
DOS, Windows 95, 98, ME, NT, XP,
Vista, Windows 7
Unix, Linux,
MAC system OS 6,7,8,9,10

43. Command Line Operating Systems
DOS is an example of a command line operating
system.
On the next slide, Notice that there are no:
Icons (pictures)
Colors
Mouse Pointer
Buttons
You have to memorize commands in order to use
this text based operating system.

44. Operating Systems: GUI
GUI stands for Graphical User Interface
Uses pictures (icons) to represent files, folders,
disk drives, modems, printers, etc.
GUI’s were created to make using a computer
easier, more interesting, non-threatening to
inexperienced users.
A mouse allows users to point at something and
click to make it work. With command line you
have to have all of the commands to make your
programs work. Here is an example of a GUI
