Assume a five-layer TCP/IP model as shown in the class notes. The initial data at the application layer is 600 bytes. A 25-byte header is added at each of the transport, network, and data link layers. There is a 4-byte trailer added at the data link layer a) Sketch headers/trailers being added at each level (similar. to Chapter 2 notes slide 14, but show 2. the number of bytes in each section of the message) (5 pts) b) How many total bytes are sent to the hardware? (2 pts) c)What percentage of the bytes sent to the hardware is the original application layer data? (2 pts) d) What percentage of the bytes sent to thie hardware is overhead? (2 pts) 3. (8pts) Discuss Eight computer terms listed below as related to computer network a. Logical topology vs physical topology b. Electromagnetic interference (EMI) c. Bandwidth d. Single mode fiber (SMF) vs Multimode fiber (MMF) e. Polyvinyl chloride (PVC) vs Plenum cable f IEEE 80213 vs IEEE 802.11 g. Structured cabling h. Telecommunication room vs attenuation i Cable certifier j Optical time domain reflectometer (OTDR)
