2. DEFINITION
A computer is a machine or device that
performs processes, calculations and
operations based on instructions
provided by a software or hardware
program. It is designed to execute
applications and provides a variety of
solutions by combining integrated
hardware and software components.
4. TYPES OF COMPUTERS
Mainframe computers. Large, powerful computers that are used for centralized
storage, processing, and management of very large amounts of data.
Microcomputers. ...
Minicomputers. ...
Notebook/laptop. ...
PDA;Personal Digital Assistant. ...
Supercomputers. ...
Netbook. ...
Embedded computer.
5. SUPERCOMPUTER
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).
Inventor: Seymour Cray
6. MAINFRAME COMPUTER
Mainframes (also called "big iron") are powerful computers used for large information processing
jobs. They are mainly used by government institutions and large companies for tasks such as
census, industry and consumeOriginally Answered: What are some examples of mainframe
computers? Currently IBM system z is the primary mainframe. Depending upon the definition, IBM
isystem computers are sometimes considered mainframes. Burroughs, Fujitsu, Hitachi, and
Compaq (DEC) make or made computers considered mainframes.May 21, 2018r statistics,
enterprise resource planning, and financial transaction processing.
7. SEVER COMPUTER
A server is a computer that provides data to other computers. It may serve
data to systems on a local area network (LAN) or a wide area network
(WAN) over the Internet. Many types of servers exist, including web
servers, mail servers, and file servers. Each type runs software specific
to the purpose of the
8. WORKSTATION COMPUTER
A workstation is a special computer
designed for technical or scientific
applications. Intended primarily to be
used by one person at a time, they are
commonly connected to a local area
network and run multi-user operating
systems.
Examples
Unix
cpu
Laptop
gpu
9. BLOCK DIAGRAMS OF COMPU6TER
A block diagram is a diagram of a system in which the principal parts or
functions are represented by blocks connected by lines that show the
relationships of the blocks. They are heavily used in engineering in
hardware design, electronic design, software design, and process
flow diagrams.
10. PC( PERSONAL COMPUTER)
A personal computer (PC) is a multi-purpose computer whose size,
capabilities, and price make it feasible for individual use.[1] Personal
computers are intended to be operated directly by an end user, rather
than by a computer expert or technician. Unlike large costly
minicomputer and mainframes, time-sharing by many people at the
same time is not used with personal computers.
A laptop computer is designed for portability
with "clamshell" design, where the keyboard
and computer components are on one panel,
with a hinged second panel containing a flat
display screen. Closing the laptop protects the
screen and keyboard during transportation.
Laptops generally have a rechargeable battery,
enhancing their portability. To save power,
weight and space, laptop graphics cards are in
many cases integrated into the CPU or chipset
and use system RAM, resulting in reduced
graphics performance when compared to a
desktop machine. For this reason, desktop
computers are usually preferred over laptops
11. DIFFERENCE BETWWEN PC AND LAPTOP
A laptop computer,
sometimes called
a notebook
computer by
manufacturers, is a
battery- or AC-powered
personal computer gen
erally smaller than a
briefcase that can
easily be transported
and conveniently used
in temporary spaces
such as on airplanes, in
libraries, temporary
offices, and at
meetings.

12. COMPUTER AND ITS TYPES
the basic parts of a computer system are:
Monitor.
CPU (Central Processing Unit)
Keyboard.
Mouse.
Speakers.
Printer.
14. HARDWARE AND SOFTWARE
Hardware refers to the
physical elements of
a computer. ...
Examples of
hardware in a
computer are the
keyboard, the
monitor, the mouse
and the processing
unit However, most of
a computer's
hardware cannot be
seen; It's inside the
computer case.
Computer software, also
called software, is a
set of instructions and
its associated
documentations that
tells a computer what
to do or how to
perform a task.
Software includes all
different software
programs on a
computer, such as
applications and the
operating system.
