It has is making rapid progress in the development of computers, modern machinery, more efficient, one after another in rapid succession. This is due to the revolutionary changes in the field of electronics. Development can be divided into five phases, which are known to split the generations of hardware.
The product team from 1945 to 1960 with electron tubes. They were of enormous size, produces much heat and unreliable. They used punch cards. UNIVAC I (Universal Automatic Computer), built by Remington Rand in 1951, is a device of the first generation was available in stores.
The invention of the transistor in 1948 radically changed the team-building. Thermionic valves were made with transistors, replacing the computers become smaller and more reliable. The generated heat and electricity is consumed, significantly reduced. This second generation of computers often tape drives for external memory.
The third generation of computers through the use of integrated circuits (IC). They are used primarily medium-and mini-computers between 1965 and 1971.
After 1971, she led in the fourth-generation equipment. Took the large scale integration (LSI) technology. The chips were developed with this technology. The development of the LSI in a very large scale integration (VLSI) today allows) as the computer personal computers, personal computers or personal computers (PCs.
The human brain is the ultimate miracle of nature. He was always the dream of computers work exactly like the human brain. Much of the research is in progress for artificial intelligence (AI) leads to the development of fifth generation computers.
PERFORMANCE Based on the development of any device of the fourth generation of computers, we expect the development of the fifth generation of computers is not too far.
