Study Notes
High-Level Languages
- High-level programming languages are user-friendly and abstracted from hardware architecture.
- Designed to focus on programming logic rather than hardware specifics.
- Easier to understand and implement compared to low-level languages.
- Must be interpreted or compiled into machine language for execution.
- Examples include Java, Python, PHP, and Ruby.
Low-Level Languages
- Low-level languages interact directly with computer hardware and require detailed management of operational semantics.
- Often represented in binary (zeros and ones) with minimal abstraction.
- Programs can execute directly on hardware without further translation.
- Assembly language is a key type of low-level language using mnemonic codes to represent machine instructions, requiring knowledge of computer architecture.
Compilers
- Compilers translate high-level source code to low-level instructions executable by the CPU.
- Compilation output is known as object code or object module.
- The term "compiler" was introduced by Grace Hopper in the 1950s.
Compiler Phases
- Scanning: Reads source code characters and groups them to form collective meanings.
- Lexical Analysis: Converts character groups into tokens; uses regular expressions with a symbol table for recognition.
- Syntactic Analysis: Checks the arrangement of tokens based on source code grammar, ensuring correct syntax for desired results.
