TECH NEWS:
After IC, development goals became more clear: shrink the size of circuits andelectrical components. LSI can load hundreds of components in a chip. In 1980 the Very Large ScaleIntergration (VLSI) memuay thousands of components in a single chip. Ultra-LargeScale Intergration (ULSI) increase that number into millions. The ability to put up such a lot of components in a chip that was reduced in half the pieces of coin pushing fall in the price and the size of the computer. It also increases the power of work, efficiency and keterandalan the computer. The 4004 chip intl made in 1971 brought advances in IC with channel put the components of a computer, memory and control in a very small chip.
Previously, IC created to work on a specific task-specific. Now a microprocessor can be in production and then programmed to meet the entire needs of the desired. Soon every household devices such as microwave ovens, televisions and cars with electronic fuel injection equipped with microprocessor. Such developments allow people unable to use a computer.
Consumers on a home computer that is more sophisticated and can be programmed.In 1981, IBM introduced the use of (PC) for use in the home, Office, and school. The number of PCS used jumped from 2 million units in 1981 became the 5.5 million units in the year 1982. Ten years later, 65 million PCS in use.
The computer continue its evolution towards smaller sizes, than on a computer that is on the table, to become computer that can be inserted into bag (laptop), or even a computer that can be handheld (palmtop).
Its fourth-generation computer cri has:
1. Using a Large Scale Intergration (LSI). LSI can load hundreds of component in a chip.
2. Using a microprocessor and semi conductor who shaped chips for computer memory
3. efficient use of labor resources and the constraints of the computer increases
4. the computer can be used to control
equipment-other apparatus, for example: air conditioning, refrigerators, automobiles, and so on
5. connect the computers on the network-a network of local and internet network
That included a fourth-generation computer is IBM370, Apple2, IBM PC/XT, IBM PS/2, IBM PC, IBM PC/386/486, PENTIUM, PENTIUM3, PENTIUM4, Their, AMDk6, and AMDAthlon.
