Which of the following components of the computer is referred to as the administrative section ?

A computer system is often compared to an organisation in which different parts play different roles. The input unit brings data and instructions in, the output unit presents results, and the memory unit stores data and programs for use.

The Central Processing Unit is described as the administrative or managerial section because, like a manager, it directs and controls the activities of every other component. Its control unit issues the signals that tell the input unit when to bring in data, the memory unit when to store or release it, and the output unit when to display results, while its arithmetic and logic unit carries out the actual processing decisions. This coordinating and decision-making role is exactly what an administrative section does in any organisation.

Associate the Central Processing Unit with control and coordination whenever a question uses organisational language such as "administrative", "managerial", or "the brain" of the computer.
