Explain how a CRC can detect more error than a parity bit? Network A is wireless LAN technology that connects devices in a small area. Figure1 shows how the connections made. By referring to this figure, answers the following questions. M S P Master Slave Park a. What is network A? b. Describe TWO (2) main architecture in network A shown in Figure 1. Explain three types of mobility in a wireless LAN. There are five kinds of connecting devices in networks. These devices can operate in different OSI layers. Identify the correct devices below according to their OSI layer. Application Transport Network Data-link Physical P&Q R & S T Figure 2 According to Figure 2, name the devices P, Q, R, S, and T correctly. Application Transport Network Data-link Physical A backbone network allows several LANs to be connected. One of the common backbones is backbone X. This backbone is normally used as a distribution backbone to connect different buildings in an organization. Each multiple-floor building has a backbone that connects each LAN on a floor. A backbone X can be used to interconnect these LANS and backbones. a. What is backbone X? b. Based on your answer in (a), draw a diagram to show how backbone X can connect four LANs using appropriate connecting devices
