What is the transmission delay (the time needed to transmit all of a packet's bits into the link) ?

Transmission delay formula = Data size / bandwidth = (L / B) second

Explanation:

Transmission Delay

Time needed to put a package on the link. In other words, it is simply the time required to put bits of data in the cable / media. It depends on the length of the packet and the bandwidth of the network.

Packet switching is a method of transferring data to a network in the form of packets. To transfer the file quickly and efficiently over the network and minimize transmission latency, the data is divided into small pieces of variable length, called packets. At the destination, all these small parts (packages) must be reassembled, belonging to the same file. A package consists of payload and various control information. No pre configuration or resource reservation is required.
