who really wants to be the perfect computer and understanding of this Article, "Parties are to come in 'gently guide you from the basics of computers, the use of complex software in the system. Before the program starts in the system, he or she wants to understand the system components and their use. And so I want you to know the importance of computers and computer probably generations.
Defining aComputer System
The computer specialist is defined in so many ways by so many people in their field. A computer is a set of interconnected devices and interactive, with precision electronic components used to perform a default operation. But in general, a computer system can be simply defined as data to an electronic device that can accept input data, process, data is stored and provide a result with an output in a readableto form. The four basic components of a computer are a monitor keyboard, mouse and system unit.
A brief history of computing
computer history and development is always planning to go back to Charles Babbage, the father of the computer and Lady Ada Lovelace, the mother. The computer problems have now come to work without stress and was not invented much perfect stage, but we saw the way through a series of processes e. There are fiveGenerations of computers, as described briefly below:
The first-generation computer (technology Vacuum Tube)
This generation of computer developed consists of computers between 1944 and 1959. ENIAC (Electronic Numerical Integrator and Calculator), EDSAC (Electronic Delay Storage Automatic Computer) and UNIVAC 1 and 11 first-generation computer. This generation of computers were bulky, distracted a lot of heat, some have been very heavy, weighing up to 200 tons.Due to the heat, they needed special cooling system. The characteristic of this generation technique was the use of vacuum tubes as the basic elements for the logic of the computer. In terms of speed, they were very slow with the computer by successive generations in comparison.
The second generation of computers (the transistor technology)
The technology, which has the characteristics of second generation computer, was the transistor technology. Althoughdeveloped this instrument in 1948 at Bell Telephone Laboratories, was and has been widely used in the electronic world, it was not until 1959 that was introduced in the manufacture of computers. These transistors replace bulky tubes. Besides doing everything to do with the vacuum tube could be the transistor so with greater reliability, lower power consumption generates less heat, less expensive to produce and are much smaller. The computer developed between 1959and in 1964 the second generation of computers are known. Examples: IBM 7030, 7070, 7090, 7094, Communities of Series 200, UNIVAC III, Honeywell 800, etc. The development of higher programming languages like COBOL and FORTRAN computer was another innovation of the second generation were collected and 10 times faster than the first.
The third generation of computer technology (integrated circuits)
Between 1964 and 1971 the third generation of computers were developed. It 'was the technologyICs, which opened its doors to third-generation computer. In fact, we can say that the chip technology truly revolutionized information technology in itself. The chips are mounted on a small piece of silicon chips. This cam technology gradually from Small Scale Integration (SSI), which is about twenty transistors and diodes connected including through medium-scale integration (MSI), which had over a hundred transistors interconnected onSingle-chip, large-scale integration (LSI) of more than tens of thousands of transistors and diodes on a single chip. The success of the integrated circuit technology has led to faster, more reliable, cheaper computers and smaller, and their multiple responsibilities from those of previous generations. In fact it was this generation of computers for the creation of mini-computer, the power of the operations was more than the older generation, increased reliability and speed, but was much less in terms of size andCosts. You might could do a hundred times as many calculations per second and a hundred times faster than their counterparts in the second generation. Examples: IBM 31360-31370 series, CDC 6600, 7600, B5000 Municipalities and PDP-II series.
The fourth-generation computer (VLSIC Micro Technology
The large-scale integrated circuit (VLSIC), made possible by micro-technology of the period 1971-1982 has launched the fourth generation of computers. Target has VLSIC 5000-50000(Transistor), built on micro-processors. The effect of this technology is always smaller, but more and more trivialized powerful computers, the speed and reliability than previous generations. This was also produced micro-computer that could be the subject of the first-generation mainframe computer to do a thousand times faster speed and affordable to individuals. This generation has also produced a number of software packages such as word processing packagesGraphics, games, software spreadsheet and database management systems. network capacity has been strengthened in this period. Examples of the fourth generation of computers include IBM 3033, HP 3000 Mini-computer, Apple II, municipalities B7700.
Fifth Generation Computer (It was artificial intelligence)
The technology of this generation of computers features Super Large Scale Integration (ULSI), Ultra Large Scale Integration (ULSI), parallel processing, artificialIntelligence, natural language processing, pattern recognition and expert system. The characteristics of this generation of computers have their enormous speed and power. The continuing miniaturization of computers is the need of the moment, newest, smallest, most powerful computers are seen every day. powerful microcomputers have now exceeded the performance of the mainframe days of age. Mother Pentium II with clock speeds exceeding 300 MHz and memory on the hard drive more than 20Gigabyte with incredible abilities are now accessible to low income. Networking, local and wide area Internet are the common characteristics of this generation of computers and reduces the whole world into a global village.
