The basic components and types of computer systems Essay Example
What are the basic constituents and types of computing machine systems? Supply some descriptions with your illustrations.
The basic constituents of all computing machine systems whether they are personal computers or supercomputer all contain six basic constructing blocks: input. end product. memory. arithmetic/logical unit. control unit and files. A computing machine system needs input devices for come ining informations into the computing machine for processing. The most common input devices are keyboards and mice. Input devices have now expanded to other methods such as voice input. magnetic ink character acknowledgment ( MICR ) . Optical character acknowledgment ( OCR ) . scanning saloon codification label. etc. The end product devices are used to bring forth the consequences of the processing done by the computing machine. The most common end product devices include computing machine screen or proctor. press
...man. or composing end product on Cadmium or DVD. Computer memory or chief memory holds the plan instructions and informations. All information flows are to and from memory.
Arithmetical and Logic Unit consist of improbably little incorporate circuits on a Si bit. It is chiefly responsible for arithmetic map of add-on. minus. generation and division computation. logical comparing and determination. Computer files storage devices sometimes called secondary or backing storage is used to hive away plans and informations when they are non being used. Secondary storage is nonvolatilizable. File devices include difficult disc thrust. magnetic tape thrusts. flash thrusts. and Cadmium or DVD. Control Unit provides the control that enables the computing machine to take advantage of the velocity and capacity of its other constituents. It controls the sequence of direction to be executed. controls the flow of informations. interpret
instructions. and it regulate clocking of processor ( Brown et al. . 2012 ) .
Types of computing machine systems are categorized into personal computers. midrange systems. mainframes and supercomputers. Personal computers are chiefly used for personal computer science or little concern processing. Personal computers cost from $ 200 to $ 4. 000. illustrations of personal computers are smartphones. tablet Personal computer. desktop Personal computers. laptop or notebook. Midrange computing machine systems cost from $ 4. 000 to $ 1. 000. 000 with power runing from 2. 500 to 250. 000 MFLOPS. its primary usage is for departmental computer science. midsized concern general computer science. web waiter. file waiter. LAN server. The major participants in this class are HP. IBM. Fujitsu and Dell. Mainframes have widest scope of applications which can be used for big concern general processing of major corporations and authorities bureaus or big web waiter. Mainframes cost from $ 500. 000 to $ 20. 000. 000. it have a really powerful processor. big sum of chief memory and a immense storage capacity.
Mainframe computing machines are really big powerful computing machine systems that are normally at the bosom of a concern. They are accessed through one or more terminuss. The dominant seller in this class is IBM other participants include Fujitsu and Unisys ( Brown et al. . 2012 ) . “Supercomputers are the true number-crunchers. with MFLOPS evaluation in surplus of 250. 000 and monetary value tickets from $ 1 million to $ 100 million or more” ( Brown et al. . 2012. pg. 34 ) . Supercomputers are used for many different grounds which include weather prediction. simulations on researches generated by
meteorologist. scientists. chemist and physicist ( Brown et al. . 2012 ) . United States is presently the leader in supercomputing states having over half of the top 500 supercomputers in the universe. However. China presently owns the world’s most powerful supercomputer called Tianhe-2 with the velocity of 33. 86 petaflops ( Service. 2013 ) .
