Computer Generations
SECOND GENERATION (1959-1964)
TRANSISTOR COMPATIBILITY LIMITED
The invention of the transistor made possible a new generation of computers, faster, smaller and with less need for ventilation. However, the cost was still a significant portion of the budget of a company. The second generation computers also used magnetic core networks instead of rotating drums for primary storage. These nuclei containing small rings of magnetic material, linked together, in which data and instructions could be stored.
Computer programs also improved. The COBOL developed during the 1st generation was already commercially available. Programs written for posicionamiento buscadores cordoba one computer could be transferred to another with minimal effort. Writing a program is no longer required to fully understand the computer hardware.
The 2nd Generation computers were substantially smaller and faster than the bulbs, and were used for new applications such as reservation systems for airlines, air traffic control simulations for posicionamiento web cordoba general use. Companies began to apply computers to record keeping tasks such as inventory management, payroll and accounting.
Navy E.U. used computers in the Second Generation to create the first flight simulator. (Whirlwind I). HoneyWell was placed as the first contestant in the second generation of computers. Burroughs, Univac, NCR, CDC, free magazine wordpress themes Honeywell, IBM’s biggest competitors in the 60s became known as the BUNCH group.
THIRD GENERATION (1964-1971)
INTEGRATED CIRCUIT, COMPUTER SUPPORT MAYOR, recruitment jobs australia multiprogramming, minicomputer:
The computers of the third generation emerged with the development of integrated circuits (silicon chips) which are placed in thousands of electronic components in best poker bonus a miniature integration. Computers became smaller again, faster, gave off less heat and were more energy efficient.
Before the advent of integrated circuits, computers were designed for math or business employment service australia applications, but not both. Integrated circuits enabled computer manufacturers to increase the flexibility of the programs, and standardize their models.
The IBM 360 one of the first commercial computer that used integrated circuits, numerical analysis was performed either as administration or processing of files. Customers could scale their posicionamiento buscadores cordoba systems IBM 360 to the larger models and could still run your existing programs. The computers work so fast that provided the ability to run more than one program simultaneously (multiprogramming).
For example the computer could be calculating payroll and taking orders at the same time. Minicomputers, with the introduction of the IBM 360 model captured 70% of the market to avoid competing directly with IBM Digital Equipment Corporation DEC redirected its efforts toward small computers. Much less expensive to buy and operate than mainframe, news mini computers were developed during the second generation but reached its peak between 1960 and 1970.
FOURTH GENERATION (1971 TO DATE)
Microprocessor, how to get rid of acne, memory chips, micro-miniaturization:
Two improvements in computer technology marks the beginning of the fourth generation: the replacement of magnetic core memories with, for the silicon chip and the placement of many more posicionamiento web en buscadores components on a chip: a product of micro-miniaturization of electronic circuits . The small size of the microprocessor chip made possible the creation of personal computers (PC Personal Computer).
Today LSI technology (large scale integration) and VLSI (very large scale integration) allow hundreds of thousands of electronic components are stored on a chip. Using VLSI, a manufacturer melbourne can make a small computer with a computer rival of the first generation that occupied an entire room.
