Study Notes
Programming Levels
Levels of Programming
-
Machine Level:
- Uses binary code (0s and 1s) that the computer's processor can execute directly.
- Very low-level, specific to a particular type of computer.
- Difficult to program and debug.
-
Assembly Level:
- Uses symbolic representations of machine code instructions.
- One-to-one correspondence with machine code.
- Still low-level, but easier to read and write than machine code.
-
High-Level Language:
- Uses words and symbols that are easier for humans to read and write.
- Compiled or interpreted into machine code.
- Examples: C, C++, Java, Python.
Characteristics of High-Level Languages
- Portability: Can be run on different types of computers with minimal modifications.
- Ease of use: Easier to learn and use than low-level languages.
- Abstraction: Focus on the logic of the program, rather than the details of the computer.
Levels of Abstraction
-
Low-Level Abstraction:
- Close to the machine, with direct access to hardware resources.
- Examples: device drivers, firmware.
-
Medium-Level Abstraction:
- Balances abstraction and control, with access to system resources.
- Examples: operating systems, embedded systems.
-
High-Level Abstraction:
- Focuses on the problem domain, with minimal concern for system resources.
- Examples: web applications, business software.

High-Level Language
- Uses words and symbols that are easier for humans to read and write.
- It is compiled or interpreted into machine code.
- Examples include C, C++, Java, and Python.
Characteristics of High-Level Languages
- High-Level Languages are portable and can be run on different types of computers with minimal modifications.
- They are easy to learn and use compared to low-level languages.
- They provide abstraction, allowing developers to focus on the logic of the program rather than the details of the computer.
