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 is a powerful computer that connects to multiple end clients so that users can access apps concurrently. A mainframe is defined as a large, powerful computer typically used for complex calculations and data processing tasks.

Detailed explanation-3: -The mainframe computer’s storage capacity of 1 million bytes (1 MB), with some 600, 000 bytes of RAM, appeared “virtually unlimited” in 1971. Today this figure appears rather modest, with nearly every smartphone providing hundred thousand times that capacity.

Detailed explanation-4: -Examples of mainframe computers include the universal automatic computer from UNIVAC series and the ZSeries mainframe computer from IBM. Another example is a system named Non-Stop by the manufacturers of Hewlett Packard.

Detailed explanation-5: -The term mainframe was derived from the large cabinet, called a main frame, that housed the central processing unit and main memory of early computers. Later, the term mainframe was used to distinguish high-end commercial computers from less powerful machines.
