Fourth Generation (1976 – 1985) : Macintosh 128k
Fifth Generation (1986 - till date) : Super computer
The attributes of computers that have made them so amazing and all around valuable are speed, exactness, persistence, flexibility and capacity limit. Allow us to examine them quickly.
Speed
Computers work at an amazing velocity. An incredible computer is equipped for performing around 3-4 million basic guidelines for every second.
Precision
Notwithstanding being quick, computers are additionally precise. Mistakes that may happen can quite often be ascribed to human blunder (erroneous information, ineffectively planned framework or defective directions/programs composed by the software engineer)
Industriousness
In contrast to individuals, computers are exceptionally predictable. They don't experience the ill effects of human qualities of fatigue and sleepiness bringing about absence of focus. Computers, in this manner, are superior to people in performing voluminous and redundant positions.
Flexibility
Computers are flexible machines and are fit for playing out any undertaking as long as it very well may be separated into a progression of legitimate advances. The presence of computers can be seen in pretty much every circle – Railway/Air reservation, Banks, Hotels, Weather estimating and some more.
Capacity
The present computers can store huge volumes of information. A snippet of data once recorded (or put away) in the computer, can never be failed to remember and can be recovered promptly.
