9. 2.1. Mainframe Computer
1. Main frame computers are known as “Colloquially” means big iron.
2. Mainframe systems are some of the most important aspects of many major businesses.
3. Not only can they process massive amounts of information, but they can do so relatively
quickly.
4. For that reason, many of the largest sectors invest in the technology as a way to easily
process billions of transactions a week.
5. Mainframe computers are utilized by large industries because they are some of the only

culture of business derived from
the information gathering and
analysis capabilities of first the
mainframe and then the PC

13. 2.2. Super Computer
1. The most powerful computers in terms of performance and data processing are the
Supercomputers.
2. These are specialized and task specific computers used by large organizations.
3. These computers are used for research and exploration purposes, like NASA uses
supercomputers for launching space shuttles, controlling them and for space exploration
purpose.
4. The supercomputers are very expensive and very large in size.
5. It can be accommodated in large air-conditioned rooms; some super computers can span
an entire building.

14. 2.2.1. Uses of Super Computer
1. Space Exploration
Supercomputers are used to study the origin of the universe, the dark-matters. For these
studies scientist use IBM’s powerful supercomputer “Roadrunner” at National Laboratory
Los Alamos.
2. ​Earthquake Studies
​Supercomputers are used to study the Earthquakes phenomenon. Besides that
supercomputers are used for natural resources exploration, like natural gas, petroleum,
coal, etc.
3. ​Weather Forecasting
Supercomputers are used for weather forecasting, and to study the nature and extent of
Hurricanes, Rainfalls, windstorms, etc.
4. Nuclear Weapons Testing
Supercomputers are used to run weapon simulation that can test the Range, accuracy &
impact of Nuclear weapons.
In Pakistan Supercomputers are used by Educational Institutes like NUST for research
purposes. Pakistan Atomic Energy commission & Heavy Industry Taxila uses supercomputers
for Research purposes.

15. Your brain is a supercomputer
and your self talk is the program
it will run
Jim Kwik

16. 2.3. Mini Computer
1. Minicomputers are used by small businesses & firms.
2. Minicomputers are also called as “Midrange Computers”.
3. These are small machines and can be accommodated on a disk with not as processing
and data storage capabilities as super-computers & Mainframes.
4. These computers are not designed for a single user.
5. Individual departments of a large company or organizations use Mini-computers for
specific purposes.
6. For example, a production department can use Mini-computers for monitoring certain
production process.

17. 2.3.1 Popular Mini Computer
1. K-202
2. ​Texas Instrument TI-990
3. ​SDS-92
4. ​IBM Midrange computers

18. 2.4. Micro Computer
 PC is an abbreviation for a Personal Computer, it is also known as a Microcomputer.
 Its physical characteristics and low cost are appealing and useful for its users.
 The capabilities of a personal computer have changed greatly since the introduction of
electronic computers.
 Today a personal computer is an all-around device that can be used as a productivity tool,
a media server and a gaming machine.
 The modular construction of the personal computer allows components to be easily
swapped out when broken or upgrading.

20. 2.4. Micro Computer
• Desktop computers, laptops, personal digital assistant (PDA), tablets & smartphones are
all types of microcomputers.
• The micro-computers are widely used & the fastest growing computers.
• These computers are the cheapest among the other three types of computers.
• The Micro-computers are specially designed for general usage like entertainment,
education and work purposes. Well known manufacturers of Micro-computer are Dell,
Apple, Samsung, Sony & Toshiba.
• Desktop computers, Gaming consoles, Sound & Navigation system of a car, Netbooks,
Notebooks, PDA’s, Tablet PC’s, Smartphones, Calculators are all type of Microcomputers.

21. “Being in the microcomputer business is like going
55 miles an hour 3 feet from a cliff.
George Morrow

22. 3. LATEST COMPUTERS

23. 3.1. Workstations
 Workstations are high-end, expensive computers that are made for more
complex procedures and are intended for one user at a time.
 Some of the complex procedures consist of science, math and engineering
calculations and are useful for computer design and manufacturing.
 Workstations are sometimes improperly named for marketing reasons.
 Real workstations are not usually sold in retail, but this is starting to change;
Apple's Mac Pro would be considered a workstation.
 The movie Toy Story was made on a set of Sun (Sparc) workstations [1]
 Personal Computer or PC

24. 3.2. Smartphones
 Do you own a smartphone?
 Your smart phone is a computer! Most smartphones run iOS or Android.
 Android is an operating system that is based on Linux. Smartphones are becoming
exponentially faster and also have an exponentially increasing data capacity.
 These two devices have many limitations such as processing power, memory, energy usage
and screen size.
 They also have different input methods such as (1) numeric keypad (2)small QWERTY
keypad with navigation keys or touch gestures, (3) an onscreen and (4) voice input

Embedded Computers
 Embedded computers can be compared to "computers on a
chip".
 All in one so to speak. You will find them in all kind of
apparels that surround us.
 Washing machines, ticket machines at the subway, camera's,
cars, motors, sewing machines, clocks.
 Everywhere needing something to regulate, control of check
something.
 Historically, embedded computing is associated with self
contained preprogrammed computing.
 Meaning there are mostly no connections outside the
environment where that particular type of computing takes
(physically) place and influences the working of that
embedded computing device.

27. • Infographic Style
• Infographic Style
Cloud Computers
 Cloud computing is the delivery of on-demand computing
services -- from applications to storage and processing power
-- typically over the internet and on a pay-as-you-go basis.
• Rather than owning their own computing infrastructure or data
centers, companies can rent access to anything from
applications to storage from a cloud service provider.
• One benefit of using cloud computing services is that firms can
avoid the upfront cost and complexity of owning and
maintaining their own IT infrastructure, and instead simply pay
for what they use, when they use it.

28. According to size Computer is divided into
how many types?
The Computer is classified into 4 tyes
According to size:
Mainframe Computer, Super Computer,
Mini Computer and Micro Computer

29. Can you differentiate the super Computer
and Mainframe Computer?
 Complex Problems vs Large Storage
 Speed: BIPS vs MIPS
 Size: Larger vs smaller
 Cost: expensive vs less expansive
 Operating System (O.S) : Linux vs multi operating System
 Built :Specific vs general purpose

30. What is the advantage of using Cloud
Computing?
