Study Notes

Computer Languages

  • A computer language is a set of instructions that a computer can understand and execute.
  • Enables users to communicate with computers and provide instructions to perform specific tasks.
  • Each language has a specific syntax which is like the grammar of the language.

Compilers and Interpreters

  • Both compilers and interpreters translate human-readable code into machine-readable instructions.
  • A compiler translates the entire program into machine code at once before execution.
  • An interpreter translates the code line by line as it is being executed.

Low-Level Languages

  • Low-level languages are closer to the computer's hardware and are more difficult for humans to understand.
  • Examples of low-level languages include assembly language and machine code.
  • They provide direct control over the computer's hardware.

High-Level Languages

  • High-level languages are designed to be easier for humans to read and write.
  • Examples of high-level languages include Python, Java, and C++.
  • They abstract away the complexities of the hardware, making it easier for developers to focus on the logic of the program.

Communication between User and Computer

  • Computer languages provide a bridge between a user and a computer, allowing the user to give instructions that the computer can understand.
  • It allows users to instruct a computer to perform various tasks, from simple calculations to complex simulations.

Difference Between Low-Level and High-Level Languages

  • Low-level languages are closer to the hardware and are more difficult to learn and use.
  • High-level languages are closer to human language and are easier to understand and program with, but they may be less efficient.

Syntax and Computer Understanding

  • Syntax is the set of rules that defines how the language should be written.
  • The specific syntax of each language enables the compiler or interpreter to correctly translate the code into machine-readable instructions.

Instructions

  • Each language has a set of commands called "instructions" that specify an action for the computer to perform.
  • With a language, a user can provide a sequence of instructions to a computer, guiding its actions according to the desired outcome.
