In this guide, you will find over 50 terms explained simply. ### 1. **Algorithm** A set of step-by-step instructions to solve a problem or perform a task. Think of a recipe: each step leads you to the final result. ### 2. **API (Application Programming Interface)** An interface that allows two programs to communicate with each other. It's like a menu at a restaurant: you choose what you want, and the kitchen (program) prepares the dish. ### 3. **Backend** The "behind the scenes" part of an application or website, which manages data, logic, and operations. It's like a car engine: you don't see it, but it makes everything run. ### 4. **Big Data** Huge amounts of data that require special tools to be analyzed. Imagine having to count all the grains of sand on a beach: it's a massive job! ### 5. **Bit** The smallest unit of information in computing. It can be 0 or 1. It's like a single letter in an alphabet. ### 6. **Bug** An error in a program's code that causes incorrect behavior. It's called a "bug" (insect) because, in the early days of computing, a real insect caused a computer malfunction! ### 7. **Cache** A temporary memory that stores frequently used data to speed up operations. It's like keeping your favorite tools within reach instead of going to the garage every time. ### 8. **Cloud** A system for storing and accessing data via the internet, instead of on your computer's hard drive. It's like having a safe deposit box accessible from anywhere. ### 9. **Cybersecurity** The practice of protecting systems, networks, and programs from digital attacks. It's like locking your house to prevent thieves from entering. ### 10. **Database** An organized collection of data, easily accessible and manageable. Think of it as a gigantic digital filing cabinet. ### 11. **DNS (Domain Name System)** A system that translates domain names (like google.com) into IP addresses that computers can understand. It's like the phone book of the Internet. ### 12. **Framework** A pre-built structure that simplifies software development. It's like having the skeleton of a house: you just have to add walls and furniture. ### 13. **Frontend** The part of an application or website that users interact with. It's what you see and touch on the screen. ### 14. **Git** A version control system used to track changes in code. It's like a time machine for your projects. ### 15. **HTML (HyperText Markup Language)** The language used to create the structure of web pages. It's the skeleton of a website. ### 16. **HTTP/HTTPS** Protocols for transmitting data on the web. HTTPS is the secure version (the padlock you see in the browser). ### 17. **IDE (Integrated Development Environment)** Software that combines tools for writing, testing, and debugging code. It's like a complete workshop for programmers (e.g., VS Code). ### 18. **IP Address** A unique number that identifies a device on a network. It's like a home address, but for computers. ### 19. **JavaScript** A programming language used primarily to make web pages interactive. ### 20. **JSON (JavaScript Object Notation)** A lightweight format for data exchange between systems, easy to read for both humans and machines. ### Other Terms For more detailed guides and insights, visit [docs.highmark.it](https://docs.highmark.it) Guide created by HighMark - All information and contacts on my [official website: Highmark.it](https://highmark.it/)
