Computer networks Quiz1 9/8/2020 Last Date 12/8/2020 Question 1 Why communication protocols are realized using a layer model? The protocols can be executed faster. Using layers, it is possible to respond faster to changes in requirements (e. g. new hardware, new protocols). The amount of data transferred can be reduced using layered protocols. A complex communication task is solved more easily when split up on multiple layers.
