How an Ethernet Worked?
The operation of Ethernet can be explained in simple terms as follows:
Each computer on the Ethernet Network, also called as a node, operates independently of all other nodes. All nodes attached to an Ethernet are linked to a shared medium over which the Ethernet signals travel serially, one data bit at a time.
To send data a station first listens to the channel and when the channel is idle the station transmits its information in the form of an Ethernet frame, or packet. The Ethernet rules (protocol) are explained in such a way that each node gets a fair amount of frame transmission opportunity.
When the signal hits to each other, collision accord.
What are the key elements of protocols? The key elements of protocols are a. Syntax It refers to the structure or format of the data that is the order in which they a

What is WDM? WDM is conceptually the similar as FDM, except that the multiplexing and demultiplexing includes light signals transmitted by fiber optics channel.
Q. Multimode for transmitting optical signals? - Multiple beams from light source travel through core at different paths - Multimode step-index fiber Density remains
Source to Destination Data Transfer - Datagram approach - Each packet is treated independently. - Every pkt will take its own path to reach the destination. - There i
What can be done to fix signal attenuation problems? A common way of dealing with like problem is to use repeaters and hub, because it will help regenerate the signal and thus
