Explanation

Explanation 1. UNIVAC stands for Universal Automatic Computer.It was the first computer for commercial purpose which was produced in United States. It was made by John Mauchly and J. Presper Eckert.

Explanation 2. CD - ROM is an example of Secondary Memory. It stands for Compact Disc- Read Only Memory. It is a kind of optical disc containing data.

Explanation 3. The basic operations performed by a computer are Logical Operation, Arithmetic operation and storage. The ALU and CU of computer perform these tasks respectively.

Explanation 4. The small piece of semiconductor material usually made of silicon on which the IC is embedded is known as chip.Primary memory chip and microprocessor chip are the main two chips of computer.

Explanation 5. For the fourth generation of computer, the Microprocessors are used as the Switching Devices. Very Large Scale Integrated or VLSI circuits are used in this computer.

Explanation 6. The Hybrid Computer resembles both digital and analog computer.The digital part normally provides the numerical and logical operations, while the analog part solves the differential equations and complex mathematical equations.

Explanation 7. Supercomputers are focused to execute few programs as fast as possible while mainframe executes less amount of data. The mainframe computer is not very powerful like super computer. This is the main difference between two of them.

Explanation 8. ICs are related to third generation of the computer. The third generation was made in the time period from 1965 to 1971. The third generation computers used the Integrated Circuits (ICs) instead of transistors.

Explanation 9. The storage capacity of magnetic disc depends on the Bits per inch of the track, Tracks per inch of the surface and Disc pack in disc surface.

Explanation 10. The ALU of a computer responds to commands coming from the Control Section. ALU stands for Arithmetic Logic Unit (ALU) which performs the arithmetical and logical operations. It is one of the fundamental blocks of the CPU of the computer.

Explanation 11. The main memory of a computer is also called the Primary Memory. It is of two types- RAM (Random Access Memory) and ROM (Read Only Memory).

Explanation 12. Vacuum Tubes and Valves are the chief component of the first generation computer. It uses the vacuum tubes for the circuitry and the magnetic drums for the purpose of memory. It was very large in size.

Explanation 13. Plotter is needed to to produce high quality graphics in colour. It is the kind of the printers used for the computers. These use vector graphics to print on the paper of very large size.

Explanation 14. Keyboard and Screen are the Dumb Terminals. It is an output device which accepts the data from CPU but has no processing capabilities.

Explanation 15. ASCII stands for American Standard Code for Information Interchange. Computers can understand only numbers. The ASCII code is a numerical representation of characters like "a" or "@".
