Detailed explanation-1: –Encoding converts the stream of bits into a format recognizable by the next device in the network path.
Detailed explanation-2: -Throughput is the measure of the transfer of bits across the media over a given period of time. Due to a number of factors, throughput usually does not match the specified bandwidth in Physical layer implementations such as Ethernet.
Detailed explanation-3: -In data transmission, network throughput is the amount of data moved successfully from one place to another in a given time period. Network throughput is typically measured in bits per second (bps), as in megabits per second (Mbps) or gigabits per second (Gbps).
Detailed explanation-4: -Purpose of the Physical Layer The OSI physical layer provides the means to transport the bits that make up a data link layer frame across the network media. This layer accepts a complete frame from the data link layer and encodes it as a series of signals that are transmitted onto the local media.
