First Generations Computers (1945-1956)
With the onset of the second world war, governments sought to develop computers to exploit their potential strategic importance. This increased funding for computer development projects hastened technical.American efforts produced a broader achievement Howard H Al ken a Harvard engineer working with IBM, succeeded in producing an all-electronic calculate by 1944. The purpose of the computer was to create ballistic charts for the U.S.Navy. It was called Mark 1 an electronic relay computer.
The features of first generation of modern computers they are:
* Vacuum tubes for internal operations.
* Magnetic drums were used for memory.
* Processing speed is very slow.
* It is very expensive.
* It do not have much memory.
Second Generation Computer (1956-1963)
In 1948, the invention of the transistor greatly changed the computer's development. The transistor was at work in the computer by 1956. Coupled with early advances in magnetic-core memory, transistors led to second generation computers that were smaller, faster, more reliable and more energy-efficient than their predecessors. The first large scale machines to take advantages of this transistors technology were early supercomputers.
The features of second generation of modern computers they are:
* Transistors were used for internal operations.
* Magnetic cores were used for main memory.
* High level language were used.
* Magnetic tapes and disks were used.
* The systems were faster, small in size, cheaper and power full.
Third Generation Computer (1964-1971)
As a result, computer became ever smaller as more components were squeezed on to the chip. The third generation computer was announced in1964 by IBM with its 360 line of computers, which used integrated circuits in the hardware. Another third generation development included the use of an operating system that allows machines to run many different programs at once with a central program that monitor and coordinated the computer's memory.
The features of third generation of modern computers they are:
* Integrated circuits on silicon chips were used for internal operations.
* Minicomputers were introduced.
* Emergence of the software industry.
* Systems were totally used for general purpose.
* The systems were faster, cheaper and power full.
Forth Generation Computer (1971-Present)
Such condensed power allowed every day people to harness to a computer's power. By the mid 1970's computer manufacture sought to bring computer to general consumers. These minicomputers came complete with user friendly software packages that offered even non-technical user an array of applications most popularly word processing and spreadsheet program's In 1981 IBM introduce its Personal Computer to use in the home.
The features of forth generation of modern computers they are:
* Introduction of microprocessor.
* Use of chips for memory.
* Microcomputers and personal computers were used.
* Hardware failures were negligible.
* The systems were faster, cheaper and size is small.
Fifth Generation Computer (Present-Beyond)
Fifth generation computer will incorporate artificial intelligence which will not be far different form that of human intelligence and will store reservoirs and decisions. They will process non numerical information such as pictures and graphs. In these systems intelligence will be greatly improved and when compared to then conventional machine, the man machine interface will be closer to the human system.
The features of fifth generation of modern computers they are:
* Development of storage technology.
* Development of robots.
* Computers are more intelligent.
* Development of supercomputer.
* System are more power full, cheaper and faster.
