FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Mainframes are data servers designed to process up to 1 trillion web transactions daily with the highest levels of security and reliability. At their core, mainframes are high-performance computers with large amounts of memory and processors that process billions of simple calculations and transactions in real time.

Detailed explanation-2: -A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.

Detailed explanation-3: -A mainframe is the central data repository, or hub, in a corporation’s data processing center, linked to users through less powerful devices such as workstations or terminals. The presence of a mainframe often implies a centralized form of computing, as opposed to a distributed form of computing.

Detailed explanation-4: -Mainframe hardware: Processing units. Early mainframes had a single processor, which was known as the central processing unit (CPU). Today’s IBM® mainframes have a central processor complex (CPC), which may contain several different types of z/Architecture® processors that can be used for slightly different purposes.

Detailed explanation-5: -Supercomputers: Supercomputers are the largest in size and the most costly computers in the world.
