Wireless LAN standard IEEE 802.11 has evolved throughout the last two and half decades. The security measures, Physical layer and MAC layers have been modified as per the need of the hour. 1.a) What are the MAC layer improvisation took place in the context of hidden node terminal and exposed node terminal since the first standard appeared, explain the problem with appropriate figures. 1.b) Mention at least four latest issues which it (IEEE 802.11) needs to deal with while being incorporated with Internet of Things (IoT). 1.c) Describe CSMA/CA and CSMA/CD? Why CSMA/CD was not preferred over CSMA/CA for WLAN? |

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.

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.

True or False: [ ] In the Ring topology, each computer acts as repeater make error detection and boosts the signal before sending it on. [ ] Ethernet is a LAN so it is placed in the second layer of the OSI reference model. [ ] UDP provides connectionless service and delivers packets quickly. In case of packet loss, UDP does not provide retransmission.
