Computer System

A computer is an electronic device that stores and processes data.
It includes both hardware and software.
Hardware refers to the physical parts of the computer.
Software provides instructions that control the behavior of hardware and direct it to perform specific tasks.

Programming Language

A programming language is a set of words, symbols, and codes that enable programmers to communicate instructions to a computer.
Languages are tailored for specific purposes such as scientific applications, business solutions, or web development.
Two types of programming languages exist:
- Low-level
- High-level

Low-level Language

A low-level language is closer to machine code and hardware instructions, making it more difficult for humans to use but more efficient for computer execution.
It is machine dependent.
Each instruction in a low-level language corresponds to a single machine instruction.
There are two types of low-level languages:
- Machine Languages
- Assembly Languages

Machine Language vs. Assembly Language

Machine language uses a series of binary digits (1s and 0s) to represent instructions. Assembly language uses symbolic instruction codes, providing more human-readable instructions.
Machine language is directly understood by the computer, while assembly language needs an assembler to translate it into machine code.
Machine language uses numbers and letters to represent binary digits, while assembly language uses meaningful names for variables, making it more understandable.

High-level Language

A high-level language is closer to human languages and further from machine code.
It is designed to be easy to read, write, and understand, allowing programmers to focus on problem-solving and algorithms.
Numerous high-level languages exist, including:
- Java
- C
- C++
- Python
- PHP
- Perl
- Ruby

High-level Language Characteristics

High-level languages are machine independent, capable of running on various computer types and operating systems.
They are also considered procedural languages.
Procedural languages provide instructions on what to accomplish and how to do it.
They use English-like words for instructions.
The code is called the source program.
Each high-level language instruction equates to multiple machine instructions.

Translators

Due to the human-readable nature of high-level languages, translators are needed to convert code into an executable form for the computer.
These translators include:
- Assembler
- Interpreter
- Compiler

Assembler

An assembler is a translator that translates assembly language source code into target machine code.

Compiler

A compiler is a specialized software tool that translates code written in a high-level language into machine code or an intermediate form for execution by a computer's processor.
It translates the entire source code before program execution.
Once compiled, the resulting executable file can be run multiple times without further translation.
Compilers check the source program for errors.

Interpreter

An interpreter translates and executes code line by line at runtime.
Execution occurs immediately, without a separate compilation step.
Interpreters are useful for scripting languages and rapid development due to their ability to allow quick testing and debugging.

Compiler vs. Interpreter

Aspect	Compiler	Interpreter
Translation	Translates the entire source code into machine code before execution.	Translates and executes one statement at a time (statement by statement).
Execution	Produces an executable file that can be run multiple times without further translation.	Executes code directly, without creating a separate executable file.
Performance	Generally faster execution since the code is translated and optimized beforehand.	Generally slower execution due to line-by-line translation.
Error Detection	Errors are detected after the entire code is compiled.	Errors are detected as the code is executed, which can make debugging easier for specific lines but harder for overall logic.
Examples	C, C++, Rust	Python, JavaScript, Ruby

Exercises

Compare interpreters and compilers.
Compare high-level and low-level languages.
Compare machine and assembly languages.
