Introduction
A computer is a machine that can be programmed to
automatically carry out sequences of arithmetic
or logical operations (computation)

Classification on computer
Computer is classified into several categories
depending on their community ability and
processing speed.these include

1. Micro Computer
2. Mini Computer
3. Mainframe Computer
4. Super Computer

Micro Computer
A microcomputer is a complete computer on a small
scale, designed for use by one person at a time.
An antiquated term, a microcomputer is now
primarily called a personal computer, or a device
based on a single-chip microprocessor. Common
microcomputers include laptops and desktops.
6
Mini Computer
Minicomputer, computer that was smaller, less
expensive, and less powerful than a mainframe or
supercomputer but more expensive and more
powerful than a personal computer. Minicomputers
were used for scientific and engineering
computations, business transaction processing,
file handling, and database management.
7
Mainframe computer
A mainframe computer, informally called a
mainframe or big iron,1 is a computer used
primarily by large organizations for critical
applications like bulk data processing for tasks
such as censuses, industry and consumer
statistics, enterprise resource planning, and
large-scale transaction processing. A mainframe
computer is large but not as large as a
supercomputer and has more processing power than
some other classes of computers, such as
minicomputers, servers, workstations, and
personal computers. Most large-scale
computer-system architectures were established in
the 1960s, but they continue
8
Super Computer
A supercomputer is a type of computer with a high
level of performance as compared to a
general-purpose computer. The performance of a
supercomputer is commonly measured in
floating-point operations per second (FLOPS)
instead of million instructions per second
(MIPS). Since 2017, supercomputers have

Hardware
Computer hardware is a collective term used to
describe any of the physical components of an
analog or digital computer. The term hardware
distinguishes the tangible aspects of a computing
device from software, which consists of written,
machine-readable instructions or programs that
tell physical components what to do and when to
execute the instructions.

Software
System software is software that directly
operates the computer hardware and provides the
basic functionality to the users as well as to
the other software to operate smoothly. Or in
other words, system software basically controls a
computers internal functioning and also controls
hardware devices such as monitors, printers, and
storage devices, etc. It is like an interface
between hardware and user applications, it helps
them to communicate with each other because
hardware understands machine language(i.e. 1 or
0) whereas user applications are work in
human-readable languages like English, Hindi,
German, etc. so system software converts the
human-readable language into machine language and
vice versa.

Input devices
Input device captures information and translates
it into a form that can be processed and used by
other parts of your computer.
12
Output devices
Output devices take information within your
computer and present it to you in a form that you
can understand.
