Data Communication and Networks MCQs Set 2

This networking MCQs set includes 25 communication and networks MCQs covers the topics such as network topology mcqs, different types of network topology, mcqs on communication devices of computer, internet protocol mcqs, dsl meaning, lan network and ISDN. This network MCQ set may help you in all UGC NET computer science exams, PPSC lecturer computer science tests, and all other computer-related jobs exams.

What is Network Topology

The physical or logical arrangement of a network is referred to as network topology. It specifies how nodes are connected to one another and where they are situated. Network topology, on the other hand, may define how data is transported between these nodes.

Types of Network Topology

Physical and logical network topologies are the two types of network topologies. Physical network topology refers to the physical signal transmission medium, whereas logical network topology describes how data flows via the network between devices, regardless of their physical link.

Network Topology Examples

Physical network topologies include star topology, mesh topology, tree topology, ring topology, point-to-point, circular, hybrid, and bus topology, which all have different node and connection configurations.
Twisted pair Ethernet, which is classified as a logical bus topology, and token ring, which is classified as a logical ring topology, are two examples of logical network topologies. Below is the network toplogy diagram which contains all topologies diagrams.
