# Programming
### 1. The Boot Process (How it all starts)

- **BIOS (Basic Input/Output System) / UEFI:** This is the first firmware that runs when you turn on the computer. It is stored directly on the motherboard.
    
- **POST (Power-On Self-Test):** The BIOS checks if all critical hardware components (CPU, RAM, storage) are working properly.
    
- **Booting:** If everything is fine, the BIOS finds the bootloader on the hard drive and loads the **Operating System (OS)** into the main memory (RAM).
    

### 2. Operating Systems (OS)

- **Definition:** The OS is the most important software running on a computer. It manages the computer's memory, processes, and all of its software and hardware. It acts as a bridge between the user and the hardware.
    
- **Windows:** The most popular OS for personal computers and gaming. It is closed-source and owned by Microsoft.
    
- **macOS:** Apple's operating system. It is built on a Unix foundation, which makes it highly stable and very popular among developers and creative professionals.
    
- **Linux:** An open-source operating system. It comes in many different distributions (like Fedora, Ubuntu, or Debian). It is the absolute industry standard for hosting web applications, databases, and running servers.

- **Browsers:** Used to access the World Wide Web (Google Chrome, Firefox).
    
- **Text Editors & Word Processors:** Used for writing unformatted plain text (Notepad) or formatted documents (Microsoft Word).
    
- **Spreadsheets:** Used for data analysis and calculations (Microsoft Excel).
    
- **Databases:** Systems for storing and managing large amounts of structured data (PostgreSQL, MySQL).
    
- **Graphical Programs:** Used for editing bitmaps or vectors (Adobe Photoshop, Figma).
    

### 4. IDE & The "Favorite Program" (Your ultimate time-killer)

Tady to úplně stáhni na sebe a svoji praxi. Komise chce slyšet, že máš k něčemu reálný vztah.

- **IDE (Integrated Development Environment):** It is a software application that provides comprehensive facilities to computer programmers for software development.
    
- **Key features of an IDE:** It usually contains a source code editor, build automation tools, a terminal, and a debugger.
    
- **My Favorite Program (Talk about your setup):** * Pick your IDE (e.g., Visual Studio Code, IntelliJ IDEA, or WebStorm).
    
    - Tell them _why_ it's your favorite: _"My favourite program is my IDE because I use it every day to build fullstack web applications. I love it because I can write my frontend in Next.js, test my Spring Boot backend, and manage my Git repositories all in one window without leaving the program."_
        

**Speaking Strategy for the Exam:**

Odpíchni se od BIOSu, to zní skvěle. Pak jednoduše popiš tři hlavní OS. Můžeš to krásně oživit tím, že zmíníš, proč na běžnou práci a kódění preferuješ třeba macOS nebo customizovaný Linux, ale když deployuješ produkční server, automaticky sáhneš po Linuxu bez grafického rozhraní. A zbytek času zabij popisem svého oblíbeného vývojářského prostředí a toho, jak ti šetří čas při psaní e-shopů a APIček.
