&8226;Look at the statements below and the following Computer Types.
&8226;Which type of computer (A, B, C or D) does each statement (1-7) refer to？
&8226;For each statement (1-7), mark one letter (A, B, C or D) on your Answer Sheet.
&8226;You will need to use some of these letters more than once.
A Microcomputer
A microcomputer is a desktop or notebook size computing device that uses a microprocessor as its Central Processing Unit, or CPU. Microcomputers are also called Personal Computers (PCs), home computers, small business computers, and micros. The smallest, most compact are called laptops. When they first appeared, they were considered single user devices, and they were capable of handling only four, eight, or 16 bits of information at one time. More recently the distinction between microcomputers and large, mainframe. computers (as well as the smaller mainframe. type systems called minicomputers) has become blurred, as newer microcomputer models have increased the speed and data handling capabilities of their CPUs into the 256 bit. or even much more bit multi-user range.
B Minicomputer
A minicomputer is a mid-level computer built to perform. complex computations while dealing efficiently with a high level of input and output from users connected via terminals Minicomputers also frequently connect to other minicomputers on a network and distribute processing among all the attached machines. Minicomputers are used heavily in transaction processing applications and as interfaces between mainframe. computer systems and wide area networks.
C Mainframe. Computer
A mainframe. computer is a high level computer designed for the most intensive computational tasks. Mainframe. computers are often shared by multiple users connected to the computer via terminals. The most powerful mainframes, called supercomputers, perform. highly complex and time consuming computations and are used heavily in both pure and applied research by scientists, large businesses, and the military.
D Supercomputer
In computer science, supercomputers are large, extremely fast, and expensive computers used for complex or sophisticated calculations. Typically they are machines capable of pipelining instruction execution and providing vector instructions. A supercomputer can, for example, perform. an enormous number of calculations required to draw and animate a moving spaceship in a motion picture. Supercomputers are also used for weather forecasting, large scale scientific modeling and oil exploration and so on and so like.
They are often used for jobs like engineering design and testing, serious decryption, economic forecasting, etc.
