Question 3. How is a minicomputer different from a mainframe?

Answer:

A minicomputer is a medium-sized, multiuser, multiprocessor computer. It is also known as a mid-range server. But mainframes are huge computers that usually take up entire rooms or floors. It is very expensive.

Question 4. What is a supercomputer?

Answer:

The fastest type of computer. Supercomputers are very expensive and are used for special applications that require huge mathematical calculations. For example, you need a supercomputer to predict the weather. Other applications for supercomputers include motion graphics, fluid dynamics, nuclear power research, and oil exploration.

Question 5. What is the difference between input and output devices?

Answer:

Input devices are used to enter into a computer. However, output devices are used to get the result from the computer. Examples of input devices are keyboard, mouse, scanner, digital camera, and so on, while output devices include a monitor, printer, projector, etc.

b) Chipset
c) BIOS

Question 8. What is the difference between serial and parallel interfaces?

Answer:

Serial port and parallel port are used to transfer data to / from a computer. When transmitted via the serial interface, only 1 bit is transmitted. Most of the PC’s serial ports conform to RS-232C or RS-422 standards. Parallel interface for connecting an external device, eg. B. printer. On personal computers, the parallel port uses a 25-pin (DB-25 type) connector and is used to connect printers, computers, and other peripheral devices that require relatively high bandwidth. It uses parallel data transmission.

Question 9. What is an interface?

Answer:

This is a communication channel through which your computer can communicate with various devices.
