Essay On Advantages And Disadvantages Of Wireless Networking

2) A bus network is a network topology in which nodes are directly connected to a branched half-duplex link called a bus. A star topology is a topology for a Local Area Network in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable, but the benefit is that if a cable fails, only one node will be brought down. Advantages of using a star topology include fast connection speed because each workstation has a dedicated cable, it will not slow down when many users are on-line and new workstations can be added without affecting the other workstations.

3) Advantages of using bus topology includes cheap installation compared to star topology because only one main cable is required,

Wireless networks are not likely to completely replace wired cables due to the reliability and speed issues.

2) Advantages of wireless networking include: users being able to move around freely within the area of the network with their device and get internet connection, the ability to share files and other resources with other devices that are connected to the network without having to be cabled to a port, wireless networks can sometimes handle a larger amount of users due to their being no limitation such as the number of connection ports.

Disadvantages of wireless networking include: extra costs and equipment to set up, setting up a wireless network can sometimes be difficult for people who are not experienced with computers, file-sharing transfer speeds are normally slower with wireless networks than cabled and wireless connections can be obstructed by everyday household items.

3) a) Modern mobile phone networks use cells because radio frequencies are a limited, shared resource. Wi-Fi can be used to connect the mobile to internet
