What is Computer ?
An electronic device which is capable of receiving information (data) in a particular form and of performing a sequence of operations in accordance with a predetermined but variable set of procedural instructions (program) to produce a result in the form of information or signals.

8. Five Generations of Computers
First Generation: Vacuum Tubes
Second Generation: Transistors
Third Generation :Integrated Circuits
Fourth Generation :Microprocessors
Fifth Generation :Artificial Intelligence

9. First Generation (1940-1956) Vacuum Tubes

10. The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, the first computers generated a lot of heat, which was often the cause of malfunctions.
First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time, and it could take days or weeks to set-up a new problem. Input was based on punched cards and paper tape, and output was displayed on printouts.
The UNIVAC (Universal Automatic Computer) and ENIAC (Electronic Numerical Integrator and Computer) computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.

11. A UNIVAC computer at the Census Bureau.
The first computer, ENIAC, was developed by Army Ordnance to compute World War II ballistic firing tables. It weighed 30 tons and used 200 kilowatts of electric power.\

12. Second Generation (1956-1963) Transistors
Transistors replace vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.
Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.

14. Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL(Common Business-Oriented Language) and FORTRAN(Formula Translation). These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.
