Study Notes
Computer Languages
- A computer language is a formal system used for instructing a computer on how to perform tasks.
Types of Programming Languages
- High-level programming languages are closer to natural languages, making them easier for humans to read and write.
- Low-level programming languages directly relate to machine architecture and are often more complex for humans.
Machine Language
- Machine language consists of binary code, using 1s and 0s to represent instructions for the computer's processor.
Writing Programs
- To write programs in specific programming languages, specialized software known as an Integrated Development Environment (IDE) is required.
Role of Interpreters and Compilers
- An interpreter or compiler translates high-level languages into machine language, allowing the program to be executed by a computer.
- Interpreters translate code line by line, while compilers translate the entire program into machine code before execution.
Characteristics of Low-Level and Object-Oriented Languages
- Low-level languages are machine-dependent, meaning that code written for one type of machine may not work on another, making them more difficult to code in.
- Object-oriented programming languages, which focus on objects and classes, are classified as high-level languages designed for easier human comprehension and use.
