22. TYPES OF
COMPUTERS

23. A computer or array of computers that act as one collective
machine capable of processing enormous amounts of
data. A supercomputer could be made up of 10, 100, 1000,
or more computers, all working together.

26. USES OF SUPERCOMPUTER

27. USES OF SUPERCOMPUTER

28. As of 2016, the largest supercomputer is the Sunway TaihuLight
in China. It consists of 40,960 RISC processors, each with 256 cores,
totaling 10,649,600 cores. The Sunway TaihuLight is capable of 93
petaflops of processing power and uses a custom operating system, called
Sunway RaiseOS.

29. TYPES OF COMPUTER
An ultra high-performance computer made for high-volume,
processor-intensive computing. A data processing system
employed mainly in large organizations for various applications.

30. USES OF MAINFRAME
Bulk data processing, process control, industry and
consumer statistics, enterprise resource planning, and
financial transaction processing.

31. Computer that is smaller, less expensive, and less powerful than
a mainframe or supercomputer, but more expensive and more
powerful than a personal computer.

32. USES OF MINICOMPUTER
Minicomputers are used for scientific and engineering
computations, business-transaction processing, file handling,

49. CALCULATOR
Is a device that performs arithmetic operations on numbers. The
simplest calculatorscan do only addition, subtraction,
multiplication, and division. More sophisticated calculators can
handle exponent ial operations, roots, logarithm s,
trigonometric functions, and hyperbolic functions.

50. SOUND & NAVIGATION
Vehicle audio is equipment installed in a car or other vehicle to
provide in-car entertainment and information for the vehicle
occupants. Once controlled from the dashboard with a few
