16) A. What characteristics do all access points in an ESS share?           B.  How can access points communicate with each other?              17)What is the purpose of the 802.11r standard?

The Open Systems Interconnection (OSI) Reference Model defines seven layers that describe standards from the physical wire all the way up to the application interfaces on computers. Each layer has a specific function, common among all devices, and a specific way of communicating with the layer above and the layer below in the stack. Answer the following questions: Why is it important to wireless networking to understand the layers of the OSI Reference Model? Fully address the questions in this discussion; provide valid rationale for your choices, where applicable; and respond to at least two other students’ views.    use at least two scholarly articles.

Laboratory Exercise Static Routing Objectives: At the end of the exercise, the students should be able to: • Assign IP addresses to PCs and routers; and Check the connectivity of all interfaces using the PING command. Principle: Routing is the basic element of data communication networks in which it is the process of selecting paths on a network along which packets are sent from a source to a destination. Routes are the path information used to guide packet forwarding. Network devices need to forward IP packets from different subnets to their destination IP subnets. Static routes are manually configured by network administrators. This can be an effective method for networks with small and simple structures and reduce the effect of bandwidth and CPU resource consumption that occurs when other protocols are implemented. Example: [Huawei] ip route-static 30.1.1.0 Procedure: PC2 Ethernet 0/0/1 GE 0/0/3 LSW1 PC1 Ethernet 0/0/1 GE 0/0/2 Device AR1 AR2 PC1 PC2 PC3 PC4 GE 0/0/1 GE 0/0/1…

1) Listen What mechanism does 802.16 use to reduce errors? OOFDM WPA OTDD O ARQ

Is it even conceivable that two different network interfaces might have the same MAC address? Is there a rationale for the action that is being taken? It it feasible to utilize the same IP address for two different network interfaces at the same time, is that possible? Is there a rationale for the action that is being taken?

This is a subjective question, hence you have to write your answer in the Text-Field given below. "Ethernet (802.3) and WLAN (802.11) use different Media Access Protocols" - If you agree with this statement, explain those protocols and reasons thereof. If not, identify that common MAC protocol.

What does the IEEE 802.1p standard entail? EXPLAIN HOW IT WORKS SHORTLY.

A & C only

Read the instructions

You need to send a document from one computer to another, and you want it to be encrypted. Because the target computer is on a different network, data must pass via one or more routers. Ethernet is the network technology on your network, while Wi-Fi is the network technology on the target network. Should this document transfer function based on what you've learnt about networking? Why do you think that is? In the italicized sections of this description, which levels of the OSI model are involved?
