Computer Networks Questions
-
Backup server
-
Dedicated server
-
Non-dedicated server
-
None of these
B
Correct answer
Explanation
A dedicated server is designed to perform a single, specific task, such as print serving or file serving, to optimize performance for that resource.
D
Correct answer
Explanation
In a star topology, all devices are connected to a central hub or switch, which manages the traffic between them.
C
Correct answer
Explanation
In a mesh topology, every device is connected to every other device, providing high redundancy and reliability.
-
A LAN
-
A good network
-
A bus topology
-
A token ring
B
Correct answer
Explanation
The listed characteristics (reliability, scalability, redundancy, security, speed) collectively describe a well-designed network. A LAN is a network size, bus and token ring are specific topologies.
-
Ethernet
-
DSL
-
Fiber optic cable
-
Coaxial cable
C
Correct answer
Explanation
Fiber optic cables transmit data as pulses of light through glass or plastic strands, allowing for very high speeds over long distances.
-
Thin Client
-
Server
-
Node
-
Token
A
Correct answer
Explanation
A thin client is a lightweight computer that relies on a central server for processing and storage, having little or no local storage of its own.
A
Correct answer
Explanation
In token ring networks, a small frame called a token is passed between nodes; only the node holding the token can transmit data, which prevents collisions.

B
Correct answer
Explanation
In a star topology, the central connection point that links all the nodes is typically a hub or a switch.

Token
-
Data collission
-
Communication disruption
-
Terminator
B
Correct answer
Explanation
A data collision occurs when two or more devices attempt to transmit data on the same communication channel simultaneously.
-
Ring
-
Bus
-
Mesh
-
Peer-to-peer
D
Correct answer
Explanation
In a peer-to-peer network, each computer can act as both a client (requesting resources) and a server (sharing resources).
-
Servers
-
Clients
-
Nodes
-
Hubs
A
Correct answer
Explanation
Servers are powerful computers dedicated to managing network resources and providing services to client machines.
C
Correct answer
Explanation
A Wide Area Network (WAN) covers a large geographic area, such as a country or the entire globe, like the Internet.

B
Correct answer
Explanation
A network is defined as a collection of computers and devices connected together to share information and resources.
A
Correct answer
Explanation
A Local Area Network (LAN) is designed for small geographic areas, such as an office, a home, or a single building.

B
Correct answer
Explanation
In a client-server model, computers that request services from a server are referred to as clients.
