- 1what is the the purpose of an NIC?To allow a node (computer) to connect to and send data across a network.
- 2what is a Hub?A device that connects Nodes together
- 3What is a Switch?A device that connects Nodes together
- 4What is a Router?It works by sending data between networks (e.g. over the internet).If the lan is to connect to the internet, a router is needed.
- 5Network Interface Card?An intelligent device that can send data to the Nodes that the data is intended for.
- 6what is a computer network?Two or more computers connected together to share information and resources
- 7what is a LAN?A LAN is a local area network and each device is called a node.(e.g.computer,printer,etc)
- 8what is a WAN?A wan is a large cover of geographical are.it uses cables,telephone lines,satellites and radio waves.
- 9What are the advantages of a computer network?Advantages of computer networking. There are several distinct advantages to networking, including: ... Resource sharing – using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money.
- 10What are the disadvantages of a computer network?Disadvantages. Purchasing the network cabling and file servers can be expensive. Managing a large network is complicated, requires training and a network manager usually needs to be employed. ... Viruses can spread to other computers throughout a computer network.
- 11What devices are needed to produce a LAN?You will need an interface card,a hub, switch,router.
- 12What 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.

- 15What are the three different network typologies?There are really three basic types of typologies. They are Star, Bus, and Ring
- 16What are the advantages / disadvantages of a Star topology?If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in network communication. More expensive than linear bus topology because of the cost of the connecting devices (network switches).
- 17What are the advantages / disadvantages of a Bus topology?Disadvantages of bus topology. Difficult to identify the problems if the whole network goes down. It can be hard to troubleshoot individual device issues. Terminators are required for both ends of the main cable
- 18What 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.
- 19What is the purpose of a router?The main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks.
- 20what 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. The hub contains multiple ports.
- 21what is a 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.

- 24what is then purpose of a modem?A modem converts digital signals generated by the computer into analogue signals which can be transmitted over a telephone or cable line and transforms incoming analogue signals into their digital equivalents.
- 25what is an IP address?A unique string of numbers separated by full stops that identifies each computer using the Internet Protocol to communicate over a network.
- 26what does HTTP stand for?HTTP stands for Hypertext Transfer Protocol Secure, and instead of acting as its own application layer protocol.
