This document provides an introduction and history of computers. It defines what a computer is and who a user is. It discusses data and information and how information technology uses computers. It then outlines the history of computers from mechanical computers in the 1600s to modern electronic computers. It describes the four generations of electronic computers from vacuum tubes to microprocessors. It concludes by defining types of computers like analog and digital and classifying computers such as supercomputers, mainframes, workstations, servers, desktops, laptops and palmtops.
A computer is a machine that can be programmed to manipulate symbols. Its principal characteristics are: It responds to a specific set of instructions in a well-defined manner. It can execute a prerecorded list of instructions (a program). It can quickly store and retrieve large amounts of data.

Classification of computers (- Minicomputers) (Microcomputers)Maryam Fida
Classification of computers]
Computers that process analog data are called analog computers. (Analog data is continuous)
The input data is not a number infect a physical quantity like temperature, pressure, speed, velocity.
Computers that accept analog input and provide analog output.
Deal with variables.
It is used for measuring physical quantities.
Special purpose computers.
Computers that accepts digital input and provide
digital output.
The input data is represented by a number (Binary Number System).
These are used for the logical and arithmetic operations.
Measure digital quantities.
Microcomputers are more commonly known as personal computers. The term "PC" is applied to IBM-PCs or compatible computers.
Full-size desktop computers are the most common type of PC.
Notebook (laptop) computers are used by people who need the power of a desktop system, but also portability.
Handheld PCs (such as PDAs, IPADs) lack the power of a desktop or notebook PC, but offer features for users who need limited functions and small size.

Minicomputers are smaller than mainframes but larger than personal computers.
Also called midrange computers.
Powerful Minicomputers usually entertain input output need of hundred of user at a time.
Example HP 3000
Minicomputers may be used as network servers and Internet servers.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. Contents
• What is Computer?
• Who is a User?
• Data & Information
• InformationTechnology (IT)
• History of Computers
• Generations
• Types of Computers
• Classification of Computers
4. What is Computer?
Definitions:
• A computer is normally considered as calculating machine
that can perform arithmetic operation at a very high speed.
• Computers are electronic devices that is programmed to
• accept data (input),
• (process) that data into useful information,
• produce (output), and then
• (store) for later use.
5. Who is a user?
• Someone that communicates with a computer
6. Data & Information
Definitions:
• DATA
A collection of raw facts and figures is called data.
It may consist of numbers, characters, symbols etc
• INFORMATION
Processed data is called information.
It is more meaningful than data.
7. InformationTechnology
• Information is data that is organized,
meaningful, and useful.
• Information technology is the use of systems
(especially computers and telecommunications)
for storing, retrieving, and sending information..
• Computer is a very important component of
information technology
11. First Generation -VacuumTubes
1. From 1946 to 1956
•It can perform 2,000 to 16,000
additions per second
•Had main memory 100 bytes
to 2 kilobytes
2. Used vacuum tubes
3.Very large machines
•special rooms to house them
with air conditioning
•specially trained technicians to
run & maintain
12. Second Generation -Transistors
1. From 1959 to around 1965
2. Smaller, faster, and more reliable
used transistors
6,000 to 3,00,000 operations/s
main memory 6 kilobytes to 1.3 megabytes
3. one-tenth the price of a 1st Generation
4. become common in larger businesses
and universities
13. Third Generation - Integrated Circuits
1. Form 1965 to around 1972
2. Used integrated circuits – many
transistors on one piece of silicon
3. Smaller, faster, more reliable, and lower
in price
• Size of a stove or refrigerator, some can fit
on desktops
• Can do 100,000 to 400,000,000 operations
per second
• Cost about one-tenth the amount of second
generation computers
4. These Computers become very common
in medium to large businesses
14. Fourth Generation - Microprocessors
1. From 1972 until now
2. Used large scale to very large scale integrated circuits
• Put more than one IC on a silicon chip
• Can do more than one function
3. smaller, faster, more reliable, and lower in price
• Size of a television or much smaller
• Can do 500,000 to 1,000,000,000 operations/second
• Cost one-tenth, or less, the amount of third generation
4. very common in homes and business
16. Analog Computers
• An analog computer recognizes data as a
continuous measurement of a physical property.
• It has no state
• Its output is usually displayed on a meter or graphs.
• Examples are Analog clock, speedo-meter of a car,
thermo-meter etc
17. Digital Computers
• It works with numbers
• They breaks all types of information into tiny units and use
numbers to represent those pieces of information.
• Everything is described in two states i.e. either ON (1) or OFF
(0).
• They are very fast and have big memory
20. Supercomputer
• A supercomputer is a computer with a high-level computational
capacity compared to a general-purpose computer.
• It comprised of multiple high performance computers working in
parallel as a single system.
• Super Computers uses thousands of processor at a same time.
• Used for nuclear weapon weather forecasting, Scientific
Simulition, oil and gas exploration or in large companies.
21. Mainframe
• Mainframes are huge computers
that could fill an entire room or
even a whole floor!
• mainframes can run multiple
instances of operating systems at
the same time.
• Mainframe are used primarily by
large organizations for critical
applications, bulk data processing
• It uses for online data storage.
• Mainframe used for transaction
processing in banking, Airlines etc
22. Workstation
• A desktop computer that has a more powerful
processor,
• additional memory (RAM, Hard drive) and
enhanced capabilities for performing a special
group of task, such as 3D Graphics or game
development.
• Multiple users can use single workstation all
together.
23. Server
• A computer that has been optimized to provide
services to other computers over a network.
• Servers usually have powerful processors, lots of
memory and large hard drives.
• Multiple CPU’s & Hard drives
24. DESKTOP
• A PC that is not designed for portability.
• you will set the computer up in a permanent location.
• Most desktops offer more power, storage and
versatility for less cost than portable computers.
25. Laptop
• Also called notebooks.
• Laptop are portable computers that integrate
the display, keyboard, a pointing device or
trackball, processor, memory and hard drive
all in a battery-operated package.
26. Palmtop
• More commonly known as Personal
Digital Assistants (PDAs)
• palmtops are tightly integrated
computers that often use flash memory
instead of a hard drive for storage.
• usually do not have keyboards but rely
on touchscreen technology for user
input.
• A slightly larger and heavier version of
the palmtop is the handheld
computer.
