A brief para on different generations of computer(1G, 2G, 3G, 4G) etc.
Answers
Second Generation (1956-1963)
Transistors replaced vacuum tubes for circuitry and magnetic drums by magnetic core technology for memory in this generation. Smaller, faster and more reliable. Second generation computers moved to symbolic, or assembly languages, COBOL and FORTRAN are also developed at these times. It still punch cards for input and printouts for output. IBM 7094, CDC 3600 computers are examples of this generation.
Third Generation (1964-1971)
IC (Integrated Circuit)are used for circuitry which drastically increased the speed and efficiency of computers. The development of Third Generation Computers resulted end of the usage of 1st and 2nd generation computers. These 3rd G Computer generate less heat then its procedure. Users interacted with 3rd G Computers through keyboards and monitors. Computer for the first time became accessible to a public. Floppy Drive (80kb) came into picture invented by IBM eg: PDP-8, CDC6600.
Fourth Generation (1971- Present)
The Microprocessor brought the 4th G of computers, as thousand of IC were built onto a single silicon chip. What in the 1st G filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer - from the CPU (Central Processing Unit) and memory to
input/output controls - on a single chip.
Answer:
First Generation (1940-1956) - It is used vacuum tubes for circuitry and magnetic drums for memory. Very large size, taking up entire rooms and very expensive. It is relied on machine language, low level language, and programming language. Input based on punch cards and paper tape, and output was displayed on printout. UNIVAC and ENIAC computers are example of this generation.
