Study Notes
Introduction to Computers & Programming
- A computer system consists of hardware (CPU, memory, hard disk, input/output devices) and software.
- Software, or computer programs, provide instructions to the computer.
- Computers cannot understand human languages, requiring the use of computer languages for communication.
Software
- Application programs perform specific tasks for users, such as word processors, spreadsheets, and games.
- System programs control the computer, including operating systems (e.g., Windows, Linux, macOS) and programs that support the execution and development of other programs.
Operating Systems
- The operating system (OS) manages and controls a computer's activities.
- Application programs require an operating system to function.
Computer Programs
- Computer programs solve problems using a set of step-by-step procedures called algorithms.
- Algorithms process inputs and produce outputs.
- Programming languages implement algorithms.
Programming Languages
- Programming languages use precise notations (syntax and semantics) to express computations unambiguously.
- Programs are often referred to as computer code.
- Coding involves writing an algorithm in a programming language.
Types of Programming Languages
- Machine language is a set of primitive instructions built into every computer, using binary code.
- Assembly language was developed to simplify programming, using mnemonics for instructions and requiring an assembler to convert it to machine code.
- High-level languages are English-like and easier to learn, but require a translator (compiler or interpreter) to convert them to machine code.
Popular High-Level Languages
- Python is widely used in web development, data science, and artificial intelligence.
- JavaScript is essential for web development, both front-end and increasingly back-end with Node.js.
- Java is used in web development, mobile apps (especially Android), and enterprise systems.
- PHP is used for server-side scripting in web development to create dynamic web pages.
Translation Process
- A compiler translates a high-level language program (source code) into machine code that the computer can directly execute.
- An interpreter simulates a computer that understands a high-level language, executing the source code instruction by instruction.
Writing Programs
- Program writing requires developing a plan (algorithm) to solve a problem and learning a programming language.
- Developing a plan involves breaking down the problem into simpler parts and describing steps to solve them.
- This can be done using flowcharts or textual descriptions (pseudocode).
Setting Up Python Development Environment
- Different setup instructions are available for Windows, Linux, and MacOS.
- Videos provide step-by-step guidance.
Testing Your Setup
- The traditional way to test programming setup is to write a program that displays "Hello World" on the screen.
