Answer: (b)

Mainframes are a type of computer that generally are known for their large size, amount of storage, processing power and high level of reliability. They are primarily used by large organizations for mission-critical applications requiring high volumes of data processing.

In general, there are a few characteristics of mainframes that are common among all mainframe vendors: Nearly all mainframes have the ability to run (or host) multiple operating systems. Mainframes can add or hot swap system capacity without disruption.

Mainframes are designed to handle very high volume input and output (I/O) and emphasize throughput computing. A single mainframe can replace dozens or even hundreds of smaller servers.

Answer: (d)

Analyzing the data or information is NOT one of the four major data processing functions of a computer.

Answer: (c)

Answer: (d)

Answer: (a)

An Analog computer works on the supply of Continuous electrical pulses.

An Analog computer works by measuring voltages and currents rather than by the process of counting. An Analog computer works on the supply of continuous electrical signals and displays output continuously. Side rule is an example Analog device in which numbers as expressed as distances.

A computer that operates with numbers represented by directly measurable quantities (such as voltages or rotations) — compare to a digital computer, a hybrid computer. This contrasts with an Analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.
