World of Computer Networking Your CCNA start - Throughput in Transmission Control Protocol/Internet Protocol (TCP/IP)

The video tutorial covers key network parameters such as bandwidth, throughput, and latency. It explains bandwidth as a physical layer parameter measured in bits per second, with examples of fiber and copper cables. Throughput is defined as the actual data transmitted over a link, and its calculation is detailed for different layers of the TCP model, considering additional headers. The tutorial also discusses throughput in network devices like switches, highlighting that real throughput is often lower than theoretical bandwidth. Finally, latency is introduced as another important network parameter.
