Answer these 10 questions in your notebook.
Q1. What is a network?
Answer: A network is a group of computers and devices connected together to share data, resources, and information.
Q2. What is the difference between LAN and WAN?
Answer: LAN covers a small area (like a home or school), while WAN covers a large area (like countries or the whole world — Internet).
Q3. What is a node? Give examples.
Answer: A node is any device connected to a network. Examples: computer, printer, smartphone, server.
Q4. What is the function of a router?
Answer: A router directs data packets between different networks and connects your local network to the Internet.
