What is a Compiler? Explain the compiler design phases?

A compiler is a plan or a presentation in computer that converts the the origin of the rules and principles transcripts in a the form of a system of symbols and and rules that are used for communication with or between computers. The highly usual and conventional purpose for expecting the alteration of the origin of the rules and laws is to produce a feasible yet workable system of services and opportunities.

Its inclined to fulfill either a few or the entire list of functions that include a study or interpretation related to lexicon to perform preliminary processing on the data, to examine the information closely, interpretation according to the science of semantics, a series of rules of conduct or procedure and the process used to make a system of rules and laws.

In order to reduce the complexity of the plan of a compiler and the system of formation, the compiler is carried out in several stages. Furthermore, it might also contain stages that are as effective and functional as possible in order to make effective and successfully designed plans or systems.
