A supercomputer is a computer with a high level of performance compared to a general-purpose computer. Performance of a supercomputer is measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).

Traditionally, supercomputers have been used for scientific and engineering applications that must handle very large databases or do a great amount of computation (or both).

Primary storage is the component of the computer that holds data. It is a part of the CPU, programs and instructions that are currently in use. Primary storage is located on the motherboard . As a result, data can be read from and written to primary storage extremely quickly.

A computer program is a sequence of instructions for performing a task designed to solve specific problems. Each program instruction is designed to be executable by a computer; computers require the capacity to execute programs in order to function.

A process which copy's data from a memory location of the computer system is termed as Reading. It is an action executed by the computer system. This process helps to acquire data from a source field and then place the data into their volatile memory for further processing.

When referring to data or storage device, writing is taking information and moving it to an alternate location.
