13. **HTML (Hypertext Markup Language):** HTML is the standard markup language for creating web pages. It defines the structure and layout of web content using tags and elements.

14. **CSS (Cascading Style Sheets):** CSS is a stylesheet language used to describe the presentation and design of HTML documents. It controls how web pages are displayed, including fonts, colors, and layout.

15. **HTTP (Hypertext Transfer Protocol):** HTTP is a protocol used for transmitting and receiving web page data on the World Wide Web.

16. **HTTPS (Hypertext Transfer Protocol Secure):** HTTPS is a secure version of HTTP that encrypts data exchanged between a web server and a user's web browser, enhancing security and privacy.

17. **PDF (Portable Document Format):** PDF is a file format developed by Adobe that preserves the formatting of documents and images, making them platform-independent and suitable for sharing.

18. **JPEG (Joint Photographic Experts Group):** JPEG is a commonly used image compression format for photographs and images, balancing file size and image quality.

19. **PNG (Portable Network Graphics):** PNG is a lossless image format known for its support of transparent backgrounds and high-quality graphics.

20. **DNS (Domain Name System):** DNS is a system that translates human-readable domain names (e.g., example.com) into IP addresses, allowing computers to locate resources on the internet.

21. **FTP (File Transfer Protocol):** FTP is a protocol used for transferring files between computers on a network, often used for website maintenance and data sharing.

22. **API (Application Programming Interface):** An API defines how software components should interact, enabling the integration of different software systems or services.

23. **GUI (Graphical User Interface):** A GUI is a user interface that uses graphical elements like icons, buttons, and windows to interact with a computer, making it more user-friendly.

24. **OS (Operating System):** An OS is system software that manages hardware resources and provides services to software applications, enabling the operation of a computer.

25. **ASCII (American Standard Code for Information Interchange):** ASCII is a character encoding standard that represents text characters using numeric codes, enabling computers to handle and display text.

26. **HTML5 (Hypertext Markup Language, version 5):** HTML5 is the latest version of HTML, introducing new features like multimedia support and improved semantics for web content.

27. **CSS3 (Cascading Style Sheets, version 3):** CSS3 is the latest version of CSS, offering advanced styling capabilities for web designers and developers.

28. **JSON (JavaScript Object Notation):** JSON is a lightweight data interchange format used for structuring and transmitting data between a server and a web application.

29. **MPEG (Moving Picture Experts Group):** MPEG is a family of video and audio compression standards used for digital video and audio encoding.

30. **Bluetooth:** Bluetooth is a wireless technology standard for short-range communication between devices, commonly used for connecting wireless headphones, speakers, and peripherals.

31. **Wi-Fi (Wireless Fidelity):** Wi-Fi is a wireless networking technology that allows devices to connect to the internet and local networks without the need for physical cables.
