Here are 15 multiple choice questions at the university level about a comprehensive overview of computer networks, introducing network protocols and standards, physical media, topologies, network devices, and communication infrastructure:
General
1. What is a computer network?
o (A) Two or more computers and devices connected to share resources and communicate with each other.
o (B) A set of rules and procedures that govern how computers communicate with each other.
o (C) A device that connects two or more computers to each other.
o (D) None of the above.
2. What are the two main types of computer networks?
o (A) Local area networks (LANs) and wide area networks (WANs).
o (B) Peer-to-peer networks and client-server networks.
o (C) Wired networks and wireless networks.
o (D) All of the above.
3. What is the difference between a protocol and a standard?
o (A) A protocol is a set of rules and procedures that govern how computers communicate with each other, while a standard is a set of specifications that define the physical characteristics of a network.
o (B) A protocol is software-based, while a standard is hardware-based.
o (C) A protocol is open and freely available, while a standard is proprietary and owned by a company or organization.
o (D) All of the above.
Network Protocols and Standards
4. What is the TCP/IP protocol suite?
o (A) A set of protocols that are used to communicate over the internet.
o (B) A set of protocols that are used to communicate over local area networks (LANs).
o (C) A set of protocols that are used to communicate over wide area networks (WANs).
o (D) All of the above.
5. What is the difference between IPv4 and IPv6?
o (A) IPv4 is the older version of the internet protocol, while IPv6 is the newer version.
o (B) IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses.
o (C) IPv4 is for wired networks, while IPv6 is for wireless networks.
o (D) None of the above.
Physical Media
6. What are the different types of physical media that can be used in computer networks?
o (A) Copper wire, coaxial cable, fiber optic cable, and wireless media.
o (B) Twisted pair cable, coaxial cable, fiber optic cable, and radio waves.
o (C) Ethernet cable, USB cable, HDMI cable, and Bluetooth.
o (D) None of the above.
7. What are the advantages and disadvantages of using copper wire in computer networks?
o (A) Copper wire is inexpensive and easy to install, but it is susceptible to interference and has a limited bandwidth.
o (B) Copper wire is expensive and difficult to install, but it is resistant to interference and has a high bandwidth.
o (C) Copper wire is only suitable for short-distance networks.
o (D) None of the above.
Network Topologies
8. What are the different types of network topologies?
o (A) Bus, star, ring, and mesh.
o (B) Physical, logical, and hybrid.
o (C) Client-server, peer-to-peer, and distributed.
o (D) None of the above.
9. What are the advantages and disadvantages of using a bus topology?
o (A) Bus topologies are simple to install and maintain, but they are prone to failure if a single cable breaks.
o (B) Bus topologies are more expensive to install and maintain than other topologies, but they are more reliable.
o (C) Bus topologies are only suitable for small networks.
o (D) None of the above.
Network Devices
10.What are some of the most common types of network devices?
o (A) Hubs, switches, routers, and firewalls.
o (B) Modems, bridges, and gateways.
o (C) Access points, repeaters, and antennas.
o (D) All of the above.
11.What is the function of a hub?
o (A) To connect multiple devices to a single network cable.
o (B) To forward data packets to their intended destinations.
o (C) To filter traffic and
