Four Types of Computers
Since the advent of the first computer dissimilar types and sizes of computers are contribution
different services.Types of Computers can be as big as occupy a big structure and as little as a laptop
or else a microcontroller in mobile & embedded systems.
The four basic types of computers are:
• Mainframe Computer
These computers are used for research and exploration purposes, like NASA
uses supercomputers for launched space shuttles, controlling them and for space exploration
The supercomputers are extremely costly and extremely big in size. It can be accommodate in
huge air-conditioned rooms; some super computers can extent an entire building.
On 29th July, 2015, leader of the United States, Barack Obama, permitted the growth of an
Exascale Super Computer. The Exascale Super computer will be 30 times quicker and extra
commanding than today’s fastest Super Computers. The need to expand such a elevated
presentation Supercomputer comes subsequent to China’s rush in high presentation
computing. However, the US motionless tops the list of Supercomputers with 233 high
presentation equipment. China has 37 Supercomputers but they direct the list of the mainly
influential and elevated presentation supercomputers as June 2013.
The Tianhe – 2 can achieve 100 Petaflops, i.e quadrillions of balanced point operations per
The subsequent table shows listing of top five most powerful Supercomputers in the world. You
know how to moreover view complete list of Top 500 Supercomputers in the world.
In Pakistan Supercomputers are old by Educational Institutes like NUST for research
purposes. Pakistan Atomic power payment & deep business Taxila uses supercomputers for
Supercomputers are used to revise the source of the universe, the dark-matters. For these
studies scientist use IBM’s influential supercomputer “Roadrunner” at National Laboratory Los
Supercomputers are used to revise the Earthquakes event. Besides that supercomputers are
used for natural assets detection, like natural gas, petroleum, coal, etc.
Supercomputers are used for environment forecasting, and to revise the nature and coverage
of Hurricanes, Rainfalls, windstorms, etc.
Nuclear Missiles Testing
Supercomputers are used to run weapon reproduction that can test the Range, exactness &
crash of Nuclear missiles.
• IBM’s Sequoia, in United States
• Fujitsu’s K Computer in Japan
• IBM’s Mira in United States
• IBM’s SuperMUC in Germany
• NUDT Tianhe-1A in China
The Mainframe computers can be accommodate in large airconditioned rooms because of its size. Super-computers are the fastest computers with large data storage capability, Mainframes can also process & store large amount of data. Banks
educational institutions & insurance companies use mainframe computers to store up data about their customers, students & assurance policy holders.
Popular Mainframe Computers
• Fujitsu’s ICL VME
• Hitachi’s Z800
Minicomputers are used by small business & firms. Minicomputers are moreover called as
“Midrange Computers”. These are small machines and can be accommodate on a disk with
not as processing and data storage capabilities as super-computers & Mainframes. These
computers are not designed for a particular user. Individual departments of a big company or
organizations use Mini-computers for specific purposes. For example, a produce department
can use Mini-computers for monitoring certain creation process.
• Texas Instrument TI-990
• IBM Midrange computers
Desktop computers, laptops, individual digital assistant (PDA), tablets & smartphones are all
types of microcomputers. The micro-computers are extensively used & the fastest growing
computers. These computers are the cheapest between the other three types of computers.
The Micro-computers are specially designed for general handling like entertainment, education
and work purposes. Well standard manufacturer of Micro-computer are Dell, Apple, Samsung,
Sony & Toshiba.
Desktop computers, Gaming console, Sound & direction-finding deal of a Netbooks,
Notebooks, PDA’s, Tablet PC’s, Smartphones, Calculators are all type of Microcomputers.
