​Supercomputer

Is the fastest and most powerful computer in terms of performance and data processing. It uses its power to run one program at a time.

​

​

Mainframe computer

Is not as powerful as the Supercomputer. It is designed to run multiple programs concurrently.

Minicomputer

Also known as “Midrange” computer fill the space between the mainframe and microcomputer. It is smaller than Supercomputer or Mainframe computer but bigger and more powerful than the microcomputer. They are generally used as mid-range servers.

Microcomputer

Is the most widely used computer – desktop, laptops, tablets, and smartphones. It is the cheapest among the different classes of computers. This computer is design for general usage such as entertainment, education and work purposes.

​Elements of Computer System

• ​Hardware

• ​Software

• ​Peopleware

​Hardware

Refers to the physical, tangible computer equipment and devices which provides support for major functions such as input, process, output and storage.

​Components of Computer Hardware

• ​Input Device

• ​Output Device

• ​Process Device

• ​Storage Device

​Input Device

Are composed of a device that accepts data and instructions from the user or from another computer system.

​OUTPUT DEVICE

Is any piece of computer hardware that displays results after the computer has processed the input data that has been entered.​

​PROCESS DEVICE

Is the computer’s circuitry in the system unit. It plays an important role in processing operations. It is used to process data, using instructions from the program.

STORAGE DEVICE

​Software

This term refers to the collection of electronic instructions that tells the computer what to do. It is a computer program that is installed in your computer. The diagram below shows the classification of software.​

Kinds of Software

• ​System Software

• ​Application Software

​System Software

Coordinates the activities and functions of hardware and software. It controls the operations of computer hardware and provides an environment or platform for all the other types of software to work in. It is the most basic type of software in any computer system, which is essential for other programs, applications and the whole computer system to function.

​Application Software

Is a computer program that performs a specific task.
