- 2—ROUTER
- 3HOW DOES A ROUTER WORK?A ROUTER WORKS BY SENDING DATA BETWEEN NODES
- 4WHAT DO HUBS AND SWITCHES HAVE IN COMMON?THEY SERVE AS A CONNECTION POINT FOR YOUR NETWORK EQUIPMENT
- 5WHAT IS THE DIFFERENCE BETWEEN A WAN AND A LAN?A WAN IS A WIDE AREA CONNECTION POINT AND A LAN IS A LOCAL AREA CONNECTION POINT
- 6what is an advantage of a network?Networks also allow security to be established, ensuring that the network users may only have access to certain files and applications.
- 7what is a disadvantage of a network?Purchasing the network cabling and file servers can be expensive.
- 8what are the 2 main devices that are needed for a network?hub,router,
- 9what does an nic contain?The NIC contains the electronic circuitry required to communicate using a wired connection

- 19what are the 3 different topoligies?bus,ring and star
- 20what are the advantages of a ring topology?All data flows in one direction, reducing the chance of packet collisions. A network server is not needed to control network connectivity between each workstation. Data can transfer between workstations at high speeds.
- 21what are the disadvantages of the 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. The entire network will be impacted if one workstation shuts down.
- 22what are the advantages of a star topology?Easy to connect new nodes or devices. In star topology new nodes can be added easily without affecting rest of the network. Similarly components can also be Failure of one node or link doesn’t affect the rest of network. At the same time its easy to detect the failure and troubleshoot it.
