FAQs: Common Questions About Networking Fundamentals
What is a computer network?
A computer network is a group of connected devices that share data and resources using defined communication rules and transmission methods.
What is the difference between LAN and WAN?
A Local Area Network (LAN) covers a small area such as a home or office. A Wide Area Network (WAN) spans larger geographic regions and connects multiple LANs.
Why are network protocols important?
Protocols define how data is formatted, transmitted, and received. Without them, devices would not be able to communicate effectively.
What is IP addressing in simple terms?
IP addressing assigns a unique identifier to each device on a network. This ensures data reaches the correct destination.
How does network security fit into fundamentals?
Network security protects data by ensuring confidentiality, integrity, and availability. It involves controlling access and monitoring traffic.
