What does the term 'token' refer to in the context of lexical analysis?

Step 1: Understand that lexical analysis is the first phase of compiling a programming language.
Step 2: Know that during this phase, the source code is read and processed.
Step 3: Recognize that a 'token' is a group of characters that has a specific meaning.
Step 4: Identify that tokens can represent keywords, operators, identifiers, or symbols in the code.
Step 5: Conclude that tokens are the building blocks that help the compiler understand the structure of the code.

Token – A token is a meaningful sequence of characters that represents a basic element of the programming language, such as keywords, operators, identifiers, or literals.
Lexical Analysis – Lexical analysis is the process of converting a sequence of characters (source code) into a sequence of tokens for further processing in a compiler or interpreter.
