Networking Questions and Answers
Graded A+
Question: What is the primary purpose of a network in computing?
Answer: ✔✔ The primary purpose of a network is to enable the sharing of resources and
information between multiple devices, allowing for communication, data exchange, and resource
utilization across different systems.
Question: What are the main types of networks based on their geographical scope?
Answer: ✔✔ The main types of networks based on geographical scope are Local Area Networks
(LANs), which cover a small area like an office or building, and Wide Area Networks (WANs),
which cover larger geographic areas such as cities or even countries.
Question: What is the key difference between a hub and a switch in a network?
Answer: ✔✔ A hub broadcasts incoming data packets to all devices on the network, regardless
of their destination, while a switch directs data packets only to the specific device they are
intended for, improving network efficiency and reducing traffic.
Question: What is the purpose of the OSI model in networking?
1
, Answer: ✔✔ The OSI (Open Systems Interconnection) model provides a standardized
framework for understanding and designing network protocols and communications. It divides
network communication into seven layers, each with specific functions, to simplify
troubleshooting and development.
Question: What does IP stand for, and what is its role in networking?
Answer: ✔✔ IP stands for Internet Protocol. It is responsible for addressing and routing data
packets between devices on a network, ensuring that they reach their intended destinations.
Question: What is the function of a router in a network?
Answer: ✔✔ A router connects different networks together and directs data packets between
them based on their IP addresses, facilitating communication between devices on separate
networks and managing traffic to optimize performance.
Question: What is the significance of DNS in networking?
Answer: ✔✔ DNS (Domain Name System) translates human-readable domain names (like
www.example.com) into IP addresses that computers use to identify and locate each other on the
network.
