Computer System

computing machine System Introduction &038 Definitions information processing system is an electronic blind that is use to solve various problems according to a set of book of instructions given to it A computing machine is a classmable machine that receives gossip, stores and manipulates data, and provides output in a useful format Brief History of information processing system The prototypical use of the word calculator was recorded in 1613, referring to a soulfulness who carried out calculations, or computations, and word continued to be used in that sense until middle of 20th light speed From end of 19th century onwards though, word began to take on its to a greater extent familiar meaning, describing a machine that carries out computations The history of computer development is often referred to in reference to different generations of computing devices Each generation of computer is characterized by a major technological development that fundamentally changed w ay computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and tried devices Computer multiplications First Generation (1940-1956 ) The first computers used vanity pipings for circuitry and agnetic overreachs for storehouse, and were often enormous, winning up entire rooms They were very expensive to operate and in addition to using a great deal of electricity, generated a assign of light, which was often the cause of malfunctions First generation computers relied on machine language, lowest-level program language understood by computers, to perform operations, and they could only solve peerless problem at a time Computer Generations First Generation (1940-1956 ) Input was establish on punched cards and paper tape, and output was displayed on printouts The UNIVAC and ENIAC computers ar examples of firstgeneration computing devices The UNIVAC was the first commercial computer delivered to a melodic line client, the U. S. Cens us Bureau in 1951 Computer Generations Second Generation (1956-1963 ) Transistors replaced vacuum tubes and ushered in the second generation of computers The junction transistor was invented in 1947 but did non see widespread use in computers until the late 1950s The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energyefficient and more reliable than their first-generation predecessors Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube Computer Generations Second Generation (1956-1963 ) Second-generation computers still relied on punched cards for input and printouts for output Second-generation computers move from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words High-level programming languages were as well as be developed at this time, su ch as early versions of COBOL and FORTRAN These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology. Computer Generations Third Generation (1964 -1971) The development of the co-ordinated circuit was the hallmark of the trinity generation of computers Transistors were miniaturized and placed on ti chips, called semiconductors, which drastically increased the speed and efficiency of computers Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system which allowed the device to run some(prenominal) different applications at one time with a central program that monitored the memory Computers for the first time became accessible to a mass reference because they were smaller and cheaper than their predecessors. Computer Generations Fourth Generation (1971-Present) The micro unconscious proces sor brought fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip What in the first generation filled an entire room could now turmoil in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer from the central processing nit and memory to input/output controls on a single chip In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh Computer Generations Fourth Generation (1971-Present) Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors. As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the meshwork Fourth generation computers also saw the development of GUIs, the mouse and take hold devicesComputer Generations Fifth Generation (Present and Beyond ) Fifth generation computing devices, based on artificial intelligence, are still in development, though thither are some applications, such as voice recognition, that are being used today The use of parallel processing and superconductors is helping to crop artificial intelligence a reality Quantum computation and molecular and nanotechnology provide radically change the face of computers in years to come The determination of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization miscellanea &038 Types of Computer Supercomputer s are used to process very large amounts of information including processing information to predict hurricanes, air images and navigation, and process military war scenarios Classification &038 Types of Computer Mainframes are used by government and businesses to process very large amounts of information Classification &038 Types of Computer Mini -Comput ers are similar to mainframes they are used by business and government to process large amounts of information Classification &038 Types of Computer Personal Computers (PC) are smaller and less owerful than the others. They are used in homes, schools, and small businesses. There are 3 main types of PCs Desktop take-away (Notebook/Laptop) Hand -Held ( Mobile devices/ cellphone, PDAs) Classification &038 Types of Computer Desktop Classification &038 Types of Computer Portable Classification &038 Types of Computer Hand -Held Computer Hardware These are physical parts of computer These are things that can be seen &038 affected System unit, Mouse, Keyboard, Monitor Computer Software A set of computer instructions given to computer to solve problems Stored inside computer memory Can not be touched or seen
