The main types of computer compilers are single pass compilers, multi pass compilers, cross compilers and optimizing compilers. A compiler takes one computer language, called a source code, and converts it into the target language. It enables a computer to be able to read different source codes. A compiler makes software to faster and use less memory.
Compilers are regarded as specific types of computer translators. They translate source codes from a high-level language into a lower-level language, such as machine codes and assembly code.
A cross compiler is one that can run on a computer’s operating system that is different from the operating system that the program ordinarily uses. It breaks down binary codes, understands them and allows computer programmers to gain access to the codes.
A compiler is a computer program written in implementation language. The first compiler able to compile its own source code was developed in 1962. In the 1990s, free compilers and compiler development tools were massively developed. Modern compilers are of high quality and are written in many types of languages. A compiler program that translates a low level program into a higher level one is referred to as a decompiler.
