COMPUTER FUNDAMENTALS

Detailed explanation-1: -Programming languages are formal languages that have been designed to express computations. Formal languages tend to have strict rules about syntax. For example, 3+3=6 is a syntactically correct mathematical statement, but 3=+6$ is not.

Detailed explanation-2: -A programming language is a formal language comprising a set of strings that produce various kinds of machine code output. Programming languages are one kind of computer language, and are used in computer programming to implement algorithms. Most programming languages consist of instructions for computers.

Detailed explanation-3: -Formal language is characterized by the use of standard English, more complex sentence structures, infrequent use of personal pronouns, and lack of colloquial or slang terms. Informal language allows the use of nonstandard English forms, colloquial vocabulary and typically shorter sentence structures.

Detailed explanation-4: -A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language.

Detailed explanation-5: -In automata theory, a formal language is a set of strings of symbols drawn from a finite alphabet. A formal language can be specified either by a set of rules (such as regular expressions or a context-free grammar) that generates the language, or by a formal machine that accepts (recognizes) the language.
