Question

2. What is network topology?

3
What are network communication channels?
4.
Name the different types of wireless transmission media.​

Answer 1

Answer:

Network topology is the arrangement of the elements of a communication network.

• A channel is a communication medium, the path that data takes from source to destination. A channel can be comprised of so many different things: wires, free space, and entire networks. Signals can be routed from one type of network to another network with completely different characteristics.
• Types of wireless transmission media used in communications include infrared, broadcast radio, cellular radio, microwaves, and communications satellites.

Answer 2

Answer:

2. Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. ... A wide variety of physical topologies have been used in LANs, including ring, bus, mesh and star. Conversely, mapping the data flow between the components determines the logical topology of the network.

3. A communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. ... Cable or wire line media use physical wires of cables to transmit data and information.

4. There are two types of transmission media, namely guided and unguided. Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables. Unguided transmission media are wireless, such as infrared, radio waves, and microwaves.
