Is a 'parser' the same as a 'compiler'?

No. A parser is typically one component *within* a compiler or interpreter. The parser analyses syntax; the compiler translates the whole programme.

Can 'parser' refer to a person?

In standard usage, no. It is a technical term for a program. Informally or humorously, one might call a meticulous linguist a 'human parser', but this is not standard.

What's the difference between 'parsing' and 'lexical analysis'?

Lexical analysis (scanning) breaks input into tokens (like words). Parsing takes these tokens and determines their grammatical structure according to a set of rules.

Is this word used outside of computing?

Extremely rarely. Its roots are in linguistics (parsing sentences), but its common contemporary use is almost exclusively in computer science and data processing.
