A computer system comprises hardware and software components, aiming to offer a powerful computational tool. These systems play a crucial role across diverse domains, aiding us in numerous tasks. The prevalence of the internet has significantly bolstered the utilization of computers for information sharing and communication. Computer systems empower us to store, process, display, and transmit information. Even in a basic modern computer system, multiple programs are typically required to carry out various functions effectively.

Language of computer programming

Computer is a problem solving device. When a particular problem is to be solved, it is necessary to design a set of instructions for the computer to perform.

A computer program consists of a series of instructions for the computer to run, plus any necessary data required for performing those instructions, the process of programming consists of defining those instructions and that data.

A programming language (PL) is a set of a symbols and characters, words and grammar rules that permits people to construct instructions in the format that can be interpret by the computer system. The set of instructions in a PL is known as ‘program.’ All PL languages can be divided into three categories:
*High Level Language or Problem Oriented
*Middle Level Language
*Low Level Language or Machine Oriented

The language in which binary code is used to instruct and thus write a program is known as machine language. A typical machine-level language instruction contains essentially two parts:
*Operations part: in which specifies what is to be performed.
*Address part: specifies the location of data to be manipulated.

The machine language and assembly language are examples of low level languages. Program written in these languages are not transferable from one computer to another. High level languages are the third generation languages.

These are procedure –oriented languages and are a machine independent. Programs are written in English-like statements.
