It covers important topics such as online privacy, strong passwords, cyberbullying, phishing, malware, and identity theft. Students learn safe internet practices, digital etiquette, and the importance of respecting others online. The section also explains cyber laws, copyright rules, and ethical behavior while using digital content and social media platforms. This unit helps students become responsible digital citizens by promoting awareness, safety, and ethical conduct in the online world.

Section 10: Digital Communication introduces students to the methods and tools used to exchange information electronically. It explains various forms of digital communication such as email, instant messaging, video conferencing, social media, and online collaboration platforms. Students learn the basics of composing emails, using attachments, maintaining communication etiquette, and understanding the advantages of digital communication like speed, cost-effectiveness, and global connectivity. The section also highlights safe and responsible communication practices online. This unit builds essential skills for effective communication in academic, professional, and everyday digital environments.

Section 11: Introduction to Programming Concepts introduces students to the fundamentals of coding and logical problem-solving. It explains what programming is, how computers follow instructions, and the role of programming languages. Students learn basic concepts such as algorithms, flowcharts, variables, data types, operators, and control structures (sequence, selection, iteration). The section may also include simple program examples to build logical thinking and computational skills. This unit lays the foundation for learning advanced programming languages and helps students develop structured thinking for real-world problem solving.

Section 12: HTML and Web Designing introduces students to the basics of creating web pages using HTML (HyperText Markup Language). It explains the structure of an HTML document and the use of common tags for formatting text, inserting images, adding links, and creating lists and tables. Students learn how web pages are designed, displayed in web browsers, and organized into websites. The section also covers basic page layout and simple formatting techniques.
