Introduction to Computer Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices. The various generations of computers an listed below: In there was no 'best' way of storing instructions and data in a computer memory. There were four competing technologies for providing computer memory:
Write a note on all five generations of computers discussing their characteristics. Also give examples of computers belonging to each generation.
First Generation Computers The first generation computers used thermionic values vacuum tubes and machine language was used for giving instructions. The computers of this generation were very large size and their programming was a difficult task.
Some computers of this generation are being given below: Eckert and Mauchly at the University of Pennsylvania in U. This computer, called Electronic Numerical Integrated And Calculator, used high speed vacuum tube switching devices.
It has a very small memory and it was used for calculating the trajectories of missiles. It took microseconds for addition and about microseconds for multiplication. With this the operation became faster since the computer could rapidly access both the program and data.
Wilkes at Cambridge University in and used mercury delayed lines for storage. This allowed easy implementation of program loops. This computer also used vacuum tubes. Initial applications of computers those days were in science and engineering but with the advent of UNIVAC I, the prospects of commercial application were perceived.
Though the first generation computers were welcomed by Govt. Further researches in this line aimed at removal of these limitations. Second Generation Computers A big revolution in electronics took place with the invention of transistors by Bardeen, Brattain and Shockley in Transistors were highly reliable compared to tubes.
Another major event during this period was the invention of magnetic core and development of magnetic disk for storage. These are tiny ferrite rings 0. The two directions represent 0 and 1.
Magnetic cores were used to construct large random access memories.Nov 13, · Q5. Write a note on all five generations of computers discussing their characteristics.
