Features of a computer are properties of a computer that makes it stand-out. Some of the features include:

  1. Speed
  2. Accuracy
  3. Consistency and Repetitiveness
  4. Storage
  5. Processing
  6. Automatic
  7. Versatility
  8. Non-intelligent
  • Speed:

A computer processes data at a very fast rate. It takes only a few seconds to perform a task that would be completed in hours. Most computers work in micro and nanoseconds. The speed is measured in MegaHertz (MHz) and GigaHertz (GHz).

  • Accuracy:

The correctness of the job performed by the computer depends solely on the data and programs given to the computer. The accuracy of a computer system depends on the programmer because it (the computer) will always do exactly what it is instructed to do i.e. GIGO- Garbage In Garbage Out. The errors in the computer are due to human error.

  • Consistency and Repetitiveness:

A computer will always give the same result when presented with the same set of data repeatedly using the same program and data

  • Storage:

In recent times, the storage devices of a computer have a very large capacity in terms of Terabytes, which is used for storage of data for future use. Data on computer storage devices can be easily edited, retrieved when needed, more so they can be deleted. Some measurements are listed below:

4 bit = 1 Nibble

8 bit or 2 Nibble = 1 Byte

1024 Byte = 1 KiloByte (1 KB)

*1024 KB = 1 MegaByte (1 MB)

1024 MB = 1 GigaByte (1 GB)

1024 GB = 1 TeraByte (1 TB)

  • Processing:

A computer can process at great speed a large amount of data. During processing, different operations occur such as input and output operation, text manipulation operation, etc.

  • Versatility:

Versatility is the capacity of a computer performing multiple tasks at the same time i.e. multitasking; and therefore, performing different types of work completely.

  • Automatic:

A computer is an automatic machine that works without the intervention of the user but the user is required to feed the data and make use of the result (output).
