Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

Question

Calculate the effective bandwidth for the following cases. For
(a) and (b) assume there is a steady supply of data to send; for
(c) simply calculate the average over 12 hours.
(a) 100-Mbps Ethernet through three store-and-forward
switches as in Exercise 16(b). Switches can send on one link
while receiving on the other.
(b) Same as (a) but with the sender having to wait for a 50-byte
acknowledgment packet after sending each 12,000-bit data
packet.
(c) Overnight (12-hour) shipment of 100 DVDs that hold 4.7 GB
each.

Suppose a file of 10,000 bytes is to be sent over a line at 2400 bps. A. Calculate the overhead in bits and time in using asynchronous communication. Assume one start bit and a stop element of length one bit, and 8 bits to send the byte itself for each character. The 8-bit character consists of all data bits, with no parity bit. B. Calculate the overhead in bits and time using synchronous communication. Assume that the data are sent in frames. Each frame consists of 1000 characters = 8000 bits and an overhead of 48 control bits per frame. C. What would the answers to parts (a) and (b) be for a file of 100,000 characters?
