FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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. The mainframe is critical to commercial databases, transaction servers, and applications that require high resiliency, security and agility.

Detailed explanation-2: -Mainframes are designed to handle many transactions per second, providing fast and reliable access to data. Servers are known to support fewer users. They are designed to handle a smaller workload but can be scaled up to support more users if necessary.

Detailed explanation-3: -The clients are computers that depend on the server for data and software. In a mainframe system, all the processing is done by a single, very powerful computer. Individual terminals are used to access the mainframe computer but don’t run any applications themselves.

Detailed explanation-4: -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.
