Each programming language needs a mechanism of translating source code into code understood by the computer, i.e., machine code or assembly. This is done by a compiler. A compiler is thus a fundamental tool for software development. Lexical analysis, as the f...

Lexical analysis, or scanning, is one of the most time-consuming components of the compilation process. There- fore, care must be taken when writing the lexer or the resulting compiler/assembler will be slower than it needs to be. One way to speed up software, of course, is to write ...

for a parser (that eats a series of tokens and assigns meaning to it). So yep, lexical analysis is part of any compiler (or interpreter for that matter). Sometimes there is no strict distinction between the lexical analysis and the parsing, but I think in most larger systems it is made...
