Understanding Computers

Question 1

One of the most brilliant inventions of mankind. Through this, people were able to achieve storage and process huge amounts of data

Answer 1

Computing device

Question 2

Store data in continuous form of physical quantities and perform mathematical operations simultaneously. It uses symbolic numbers to represents results. It is commonly used in industrial and scientific applications like control systems and aircraft.

Answer 2

Analog computers

Question 3

The most commonly used type of computers which use letters and numbers as inputs in processing, displaying the result in monitor and storing output memory. They are suitable for complex computations and has higher processing speed.

Answer 3

Digital computers

Question 4

Combination of analog and digital computer system. It applies the real-time speed of the analog computer and the accuracy of the digital computer in solving problem. It helps user to process both continuous and discrete data.

Answer 4

Hybrid computers

Question 5

Usually used for military purposes. These types of computers are designed to solve a restricted class of problems.

Answer 5

Special-purpose computers

Question 6

Designed to handle a wide range of problems. They are often understood to be large systems and capable of supporting remote terminal, but may also be a smaller computer lime a desktop workstation and laptop.

Answer 6

General-purpose computers

Question 7

Ultra-high-performance computers designed for high speed data processing. It stores huge amounts of data, instructions and information. They are also used as central host computers in distributed data processing system

Answer 7

Mainframe computers

Question 8

Medium-sized computers that are more powerful than microcomputers. These computers are usually designed to serve multiple users simultaneously and more expensive than microcomputers

Answer 8

Mini computers

Question 9

Computers designed to provide services to client machines in a computer network. They are extremely large in size, as they have large processors and multiple hard drives.

Answer 9
