(Select all that apply) Ethemet is a protocol that operates on the data-link layer The data-link layer assigns unique ie addresses to individual computers The data-link layer has two sub-layers, the lower sub-layer is called Logical Link Control layer, and is responsible for coordination with the physical layer The data-link layer uniquely identifies each Computer using its ARP address The data-link Layer has two sub-layers, the lower sub-layer is called Medium Access Control layer, and is responsible for coordination with the physical layer Which of the following statements are accurate for the Media Access Control Address (MAC Address)? (Select all that apply) MAC Address uniquely identifies the Network interface Card in a computer The first 24 bits of a MAC address is called an OUI MAC address is witten in hexadecimal notation The last 3 bytes of MAC address if used to identify the networkinterface card manufacturer MAC address is 6 byte long The TCPIIP model differs from the OSI model in the fact that (Select all that apply): TCPP model has 5 layers and OSI model has 7 layers Only the OSi model is a conceptual models of networking. TCP /P model is only used when network manufacturers manufacture network devices. TCPAP model describes the network whereas the OSI model describes the Operating System Interface Layers 1 - 4 in both the TCPIP model and the OSI model largely match up. The TCPIIP model focuses on packet switching networks while the OSI model focuses on circuit switching The TCP A model is used in real. life whereas the 051 model is great for teaching
