What are advantages and disadvantages of optical fiber?

Computer Fundamentals, Computer Networking, Data Communications, Definition, Pros & Cons / By / September 23, 2022

Optical Fiber Optical fiber is a type of dielectric (insulating) material, such as glass or plastic, capable of transporting light. High-speed data can be transmitted through optical fibers by total internal reflection of light. The biggest feature of optical fiber is that it transmits light signals instead of electrical signals. Currently available optical fibers have …

Write short note on Bus topology with advantages and disadvantages

Data Communications, Notes, Pros & Cons, Short Note / By / August 29, 2020

Unlike star or mesh topology, a bus topology is a multi-point connection between the nodes or devices on the network. A long cable works as backbone of the network. All the different nodes in the network connects at different points on the main cable. A connection point in the main cable for a node or device is the nearest point for the node.
