Study Notes

Computer Program Overview

A computer program consists of a sequence of instructions directing a computer on how to perform specific tasks.
Programs are typically created using computer programming languages and can vary in length from just a few lines to millions of lines.
Instructions in a program are known as program source code, while the act of creating programs is referred to as computer programming or program coding.

Importance of Computer Programs

Computers without programs are ineffective as they lack tasks to execute.
Programs can be classified into systems programs, essential for hardware and software integration, and application programs, designed for user tasks.

Types of Computer Programs

Systems Programs: Ensure smooth operation of hardware/software such as Operating Systems (Linux, Windows, Unix, Solaris, MacOS).
Application Programs: Used for everyday tasks, including word processing (MS Word), gaming, and spreadsheets (MS Excel).

Compiler and Machine Language

Computers operate using machine language, which consists of binary code (ones and zeros).
Compilers translate higher-level programming languages into machine language, enabling computers to execute programs.

Real-World Applications of Computer Programs

Common applications include MS Word, Adobe Photoshop, and web browsers like Chrome.
Programs are crucial in various fields, including graphics and special effects in filmmaking, medical examinations (ultrasounds, X-rays), and communications on mobile phones.

Programming Languages

Programming languages are structured methods for conveying instructions to a computer, each with unique syntax and grammar.
High-level programming languages (e.g., Java, Python) are user-friendly and platform-independent, while low-level assembly languages closely resemble machine code but are easier to program.

Common Programming Languages

Python: Used for AI and Machine Learning.
JavaScript: Rich interactive web development.
Java: Enterprise application development.
C/C++: Operating systems and system tools.
C#: Application and web development using .NET framework.
PHP: Web development.
SQL: Data management.

Computer Programmer Role

A computer programmer is someone skilled in writing computer programs and executing programming tasks.

Types of Programmers

Software Developers: Create applications and systems.
Game Programmers: Focus on game development.
Software Engineers: Apply engineering principles to software design.
Data Developers: Specialize in data-related tasks.
Web Developers: Build and maintain websites.
Network System Administrators: Manage and maintain computer networks.

Categories of Programming Languages

High-level Programming Languages: Abstract and user-friendly, they require compiling into machine instructions (e.g., Java, Python).
Low-level Assembly Language: More accessible than machine languages, allowing programmers to use meaningful names instead of numbers and translating into singular machine instructions.
