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.
