- 1What is a computer network?Two or more computers connected together to share information and resources.
- 2Describe A LAN?Local Area Network. Relatively small
- 3Describe a WAN?Wide Area Network. Cover a large geographical area.
- 4What are the advantages of a computer network?Resource sharing – using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money.
- 5What are the disadvantages of a computer network?Buying the computer cable and servers can be very expensive.
Viruses can spread to other computers throughout a computer network.
People can hack your computer.It encourages people to become dependent on computers.It comes with the risk of security issues. - 6What devices are needed to produce a LAN?Network Adapter. A computer needs a network adapter to connect to a network. Network Medium. Wired networks need cable.Cable Connectors.Power Supply.Router.Network Software.
- 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). A network interface card is also known as a network interface controller, network adapter, or Local Area Network (LAN) adapter.
- 8What is the purpose of a Router?The main purpose of a router is to connect multiple networks.
- 9What is the purpose of a Hub?It is a connection point for devices in a network.
- 10What is the purpose of a Switch?An intelligent device that sends the nodes across the the network.
- 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?A switch sends nodes to the network. A hub connects nodes together.
- 13What is the Internet?oun
a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols - 14What is the World Wide Web?The world wide web is a collection of webpages found on this network of computers (internet)
- 15What is the purpose of a Modem?It converts the digital signals produced by your computer into analogue signals which can be used in the telephone network
- 16What is the purpose of an ISP?An Internet service provider (ISP) is 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.
- 18What does HTTP stand for?HTTP means HyperText Transfer Protocol.
- 19What is a URL?The address of a World Wide Web page
- 20How is a URL constructed?A URL can be thought of as the "address" of a web page and is sometimes referred to informally as a "web address." ... A URL is made up of several parts. The first part is the protocol, which tells the web browser what sort of server it will be talking to in order to fetch the URL. In this example, the protocol is http.
- 21What are the three different network topologies?Bus Topology. ...
Ring Topology. ...
Star Topology. - 22What are the advantages / disadvantages of a Star topology?Disadvantages of a Star Topology. Requires more cable length than a linear topology. If the hub, switch, or concentrator fails, nodes attached are disabled. More expensive than linear bus topologies because of the cost of the hubs, etc.
- 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. The entire network will be impacted if one workstation shuts down.
- 24What are the advantages / disadvantages of a Bus topology?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. The following sections contain both the advantages and disadvantages of using a bus topology with your device
- 25List examples of data that need to be kept secureBanking details, Passwords,
- 26What is HTTPS and what is it used for?HTTP is the underlying protocol used by the World Wide Web and this protocol defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.
- 27What is encryption?The process of converting information or data into a code, especially to prevent unauthorised access.
- 28What is decryption?Decryption is the process of transforming data.
