A computer that processes analog data is known as an analog computer. Analog computers store information in physical quantities in a continuous format and use measurements to perform computation.

Businesses should expect to upgrade computer equipment on a regular basis; as companies expand, so do their processing and data needs, and hardware continues to evolve at a breakneck pace.

Computers have to be kept in a specific environment to function efficiently. Conditions such as heat, cold, dust and excessive humidity all can damage and lessen the performance of a computer.
