Computer can not do anything without a Program.
In computing, a program is a specific set of ordered operations for a computer to perform. In the modern computer that John von Neumann outlined in 1945, the program contains a one-at-a-time sequence of instructions that the computer follows. Typically, the program is put into a storage area accessible to the computer.
A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function. A computer program is usually written by a computer programmer in a programming language.
Program is a common computer term that can be used as both a noun and a verb. A program (noun) is executable software that runs on a computer. ... When "program" is used as verb, it means to create a software program. For example, programmers create programs by writing code that instructs the computer what to do.
