- 1What is a computer network?A computer network, or data network, is a digital telecommunications network which allows nodes to share resources.
- 2Describe a LANa computer network that spans a relatively small area.
- 3Describe a WANA computer network that spans a relatively large geographical area.
- 4What are the advantages of a computer network?advantages of computing network
- 5What are the disadvantages of a computer network?* 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. - 6What devices are needed to produce a LAN?Apart from the computers, and other devices like printers and faxes, a LAN has to have six essential components to function.
- 7What is the purpose of a NIC?The NIC contains the electronic circuitry required to communicate using a wired connection (e.g., Ethernet) or a wireless connection (e.g., WiFi).
- 8What 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.
- 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 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?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.
- 13What is the Internet?The internet is a global network of computers that works much like the postal system, only at sub-second speeds.
- 14What is the World Wide Web?The World Wide Web is an information space where documents and other web resources are identified by Uniform Resource Locators, interlinked by hypertext links, and can be accessed via the Internet
- 15What is the purpose of a Modem?A modem converts digital signals generated by the computer into analog signals which can be transmitted over a telephone or cable line and transforms incoming analog signals into their digital equivalents.
- 16What is the purpose of an ISP?an organisation that provides services accessing and using the Internet. Internet service providers may be organised in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.
- 17What 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.

- 20How is a URL constructed?"address" of a web page and is sometimes referred to informally as a "web address." ... A URL is made up of several parts.
- 21What are the three different network topologies?* Star Topology
* Bus Topology
* Ring Topology - 22What are the advantages / disadvantages of a Star topology?Advantages of Star Topology
In star topology new nodes can be added easily without affecting rest of the network. Similarly components can also be removed easily.
Disadvantages of Star Topology
Too much dependency on central device has its own drawbacks. - 23What are the advantages / disadvantages of a Ring topology?Advantages of Ring Topology
Each computer has equal access to resources.
Disadvantages of Ring Topology
Network is highly dependent on the wire which connects different components. - 24What are the advantages / disadvantages of a Bus topology?Advantages OF Bus Topology
It is easy to set-up and extend bus network.
Disadvantages of Bus Topology
