- 9What is the purpose of a Hub?A hub, also called a network hub, is a common connection point for devices in a network. Hubs are devices commonly used to connect segments of a LAN.
- 10What is the purpose of a Switch?The basic function that any switch is supposed to perform is to receive information from any source connected to it and dispatch that information to the appropriate destination only
- 11What is the purpose of a WAP?A wireless access point (WAP) is a hardware device or configured node on a local area network (LAN) that allows wireless capable devices and wired networks to connect through a wireless standard, including Wi-Fi or Bluetooth.
- 12What is the difference between a Hub and a Switch?Difference between a Ethernet hub, a switch, and a router. ... Ethernet hubs, switches, and routers are all devices that let you connect one or more computers to other computers, networked devices, or even other networks.

Star Topology. Star Topology: In a star network devices are connected to a central computer, called a hub - 22What are the advantages / disadvantages of a Star topology?Star Topology: Advantages and Disadvantages. In Star topology, all the components of network are connected to the central device called “hub” which may be a hub, a router or a switch.
- 23What are the advantages / disadvantages of a Ring topology?Disadvantages of ring topology. All data being transferred over the network must pass through each workstation on the network, which can make it slower than a star topology
- 24What are the advantages / disadvantages of a Bus topology?Alternatively referred to as a line topology, a bus topology is a network setup in which each computer and network device are connected to a single cable or backbone.
- 25List examples of data that need to be kept securepasswords, bank card, personal information
