Which type of computer would a small business most likely use for everyday tasks?

Computers are classified by size, processing power, and typical use. Microcomputers are the small, relatively low-cost, single-user machines such as desktop computers and laptops that are designed for everyday tasks like word processing, record keeping, and communication.

Mainframe computers and supercomputers are built for organisations that need to process enormous volumes of data or perform extremely intensive calculations, such as national banks, large research institutions, or government agencies; they are expensive, physically large, and far beyond what everyday business tasks require. Minicomputers sit between these categories and were historically used by medium-sized organisations for tasks larger than a single desktop machine could handle, but they are still more than a small business needs for routine daily operations. A small business handling ordinary tasks such as invoicing, correspondence, and simple record keeping is best served by microcomputers, which are affordable, easy to maintain, and sized for a small number of users.

Examination reminder: match the scale of the computer to the scale of the task; "everyday tasks" and "small business" point to microcomputers, while "massive data processing" points to mainframes or supercomputers.
