- 1What is a computer network?A computer network is a digital telecommunications network for sharing resources between nodes, which are computing devices that use a common telecommunications technology.
- 2Describe a LANA local-area networscAN) Wis a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.5
- 3Describe a WANA computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the telephone system.
- 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. Sharing a single internet connection – it is cost-efficient and can help protect your systems if you properly secure the 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.
If the file server breaks down the files on the file server become inaccessible. - 6What devices are needed to produce a LAN?To set up a LAN, you will need: A network switch - or a router. An ethernet cable, plus extra ones for every device you want to connect via cable. A computer.
- 7What is the purpose of a Router?A router is a switching device for networks, which is able to route network packets, based on their addresses, to other networks or devices. ... In the OSI layer model, the switching of data packets through the router is based on the address on the network layer
- 8What 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. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
- 9What is the purpose of a Switch?A switch may refer to one of many different things. For example, it may refer to part of the physical circuit components that control the flow of signals. It can be a button or lever to turn a device on or off. .

In computer networking, a wireless access point (WAP), or more generally just access point (AP), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network - 11What is the purpose of a web browser?Search Results
Featured snippet from the web
Web Browser. A web browser, or simply "browser," is an application used to access and view websites. Common web browsers include Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, and Apple Safari. - 12What is the difference between a Hub and a Switch?What Is the Difference? A hub works on the physical layer (Layer 1) of OSI model while Switch works on the data link layer (Layer 2). Switch is more efficient than the hub. A switch can join multiple computers within one LAN, and a hub just connects multiple Ethernet devices together as a single segment.
- 13What is the Internet?The internet is a global network of computers that works much like the postal system, only at sub-second speeds. ... For that to work, they use a common 'language' called TCP/IP (Transmission Control Protocol/Internet Protocol).
- 14What is the World Wide Web?The internet is a huge network of computers all connected together. The world wide web (‘www’ or ‘web’ for short) is a collection of webpages found on this network of computers. Your web browser uses the internet to access the web.
- 15What is the purpose of an ISP?An ISP provides you with Internet access, usually for a fee. Connecting to the Internet requires specific telecommunications, networking, and routing equipment. ISPs allow users access to networks that contain the required equipment, enabling users to establish Internet connectivity.
