Study Notes
High-Level Languages
- High-level languages offer a user-friendly programming environment, abstracting hardware specifics.
- Each programming language has a unique syntax and keywords tailored for specific purposes.
- Examples include Java, Python, PHP, and Ruby, all emphasizing programming logic over hardware components.
- High-level languages necessitate interpretation into machine language for execution by the CPU.
Compilers and Translators
- Computer programming languages can be classified as low-level or high-level based on abstraction.
- Linkers combine multiple object files into a single, executable file.
- Compilers translate high-level language to low-level language, while interpreters process it line by line.
- Assemblers convert assembly language into machine language.
Processor Components
- The Control Unit (CU) manages and regulates the operation of the processor, including data movement and instruction control.
- The Arithmetic Logic Unit (ALU) performs arithmetic operations and logic assertions based on control unit commands.
- Register sets provide temporary storage for data and are crucial for fast data access.
Data Operations in Processors
- Fetch instruction: Processors read instructions from memory.
- Interpret instruction: Instructions are decoded to ascertain necessary actions.
- Fetch data: Data may be read from memory or I/O modules during instruction execution.
Number Systems
- A bit is the smallest data unit, representing either 0 or 1, while a byte consists of eight bits.
- Positional number systems define value based on digit placement; hence, the value is affected by position.
- The hexadecimal number system (base-16) groups four binary bits for compact representation and encompasses digits 0-9 and letters A-F.
- In 2's complement, the most significant bit indicates the sign (0 for positive, 1 for negative).
