Computing Characteristics: The computation time was in milliseconds.

In this generation, mainly batch processing operating systems were used. The first generation computers could solve one problem at a time. Machine language uses 0s and 1s for coding of the instructions.

Software Technology : The instructions were written in machine language.

The input to the computer was through punched cards, Magnetic tape and paper tapes.

Hardware Technology: The first generation of computers used vacuum tubes for circuitry and magnetic drums for memory.

Computing characteristics (speed, i.e., number of instructions executed per second).įirst Generation (1940 to 1956): Using Vacuum Tubes.

The technology used by them (hardware and software).

In the following subsections, we will discuss the generations of computer in terms of. Currently, there are five generations of computer.

Each generation of computer is designed based on a new technological development, resulting in better, cheaper and smaller computers that are more powerful, faster and efficient than their predecessors. The evolution of computer to the current state is defined in terms of the generations of computer.

GENERATIONS OF COMPUTER The computer has evolved from a large-sized simple calculating machine to a smaller but much more powerful machine.
