What is program

 What is program?

• A set of instructions that you give to a computer so that it will do a particular task
• कंप्‍यूटर का प्रोग्राम विशिष्‍ट कार्य संपादन के लिए कंप्‍यूटर को दिए गए निर्देश
• 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. The computer gets one instruction and performs it and then gets the next instruction. The storage area or memory can also contain the data that the instruction operates on. Note that a program is also a special kind of data that indicates how to operate on application or user data.
• Computer programs can be characterized as interactive or batch in terms of what drives them and how continuously they run.               1]Interactive programs. These programs receive data from an interactive user or possibly from another program that simulates an interactive user. A command interpreter or a web browser are examples of an interactive program.   

 2]Batch programs. These programs run, do their work and then stop. A batch program can be started directly by a user, or it can be invoked to run by an interactive program. A program that computes and prints out a company payroll is an example of a batch program. Print jobs are also batch programs.                  

•  Programs are created using specific programming languages such as C++, Python, and Ruby. These are high level programming languages that are human-readable and writable. These languages are then translated into low level machine languages by compilers, interpreters, and assemblers within the computer system. Assembly language is type of low level language that is one step above a machine language and technically can be written by a human, although it is usually much more cryptic and difficult to understand.
