Definition - What does Computer mean?
A computer is a machine or device that performs processes, calculations and operations based on instructions provided by a software or hardware program. It is designed to execute applications and provides a variety of solutions by combining integrated hardware and software components.


Explain
A computer is made up of multiple parts and components that facilitate user functionality. A computer has two primary categories:
  • Hardware: Physical structure that houses a computer's processor, memory, storage, communication ports and peripheral devices
  • Software: Includes operating system (OS) and software applications
A computer works with software programs that are sent to its underlying hardware architecture for reading, interpretation and execution. Computers are classified according to computing power, capacity, size, mobility and other factors, as personal computers (PC), desktop computers, laptop computers, minicomputers, handheld computers and devices, mainframes or supercomputers.

The user has between five and 15 minutes to shut down a system normally or bring an auxiliary power source online to restore the power supply. In addition, most UPS systems also work to address power source electrical surges, sag voltage, voltage spikes, frequency instability, noise interference or harmonic distortion from the ideal sinusoidal wave form. #Explains  :- A UPS is not limited by equipment type and ensures uninterruptible power to computers, data centers or other electrically powered equipment during an unexpected power failure. UPS units vary depending on the protected equipment size, which can range ...
