| Question | Answer |
| what is a computer network? | A computer network is a network wich is full of computers and you can share information with each other. |
| describe a LAN | a LAN is a local area network it is mostly in one building/room. |
| describe a WAN | A computer network that spans a relatively large geographical area. |
| what are the advantages of a computer network ? | Advantages of computer networking. ... Resource sharing – using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money. |
| what 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. |
| what devices are needed to produce a LAN | Cable Connectors. ... Power Supply. ... Hub/Switch/Router. ... Network Software. |
| what is the purpose of a NIC ? | The NIC contains the electronic circuitry required to communicate using a wired connection. |
| what 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. |
| what 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. |
| what 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. |
| hat 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 |
| what is the difference between a hub and a switch ? | A switch is used to connect various network segments. A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). |
| what is the internet ? | a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols. |
| what is the world wide web ? | an information system on the Internet which allows documents to be connected to other documents by hypertext links, enabling the user to search for information by moving from one document to another. |
| what 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 |
| what is the purpose of an ISP ? | Internet service providers may be organised in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned |
| what 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. |
| what does http stand for | HTTPS stands for Hypertext Transfer Protocol Secure, and instead of acting as its own application layer protocol, it uses separate protocols called SSL (Secure Sockets Layer) and TLS (Transport Layer Security) |
| what is a URL ? | the address of a World Wide Web page. |
| how was 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.4 Se |
| What are the three different network typologies? | Mesh Topology. Mesh Topology: In a mesh network, devices are connected with many redundant interconnections between network nodes. ... Star Topology. Star Topology: In a star network devices are connected to a central computer, called a hub. ... Bus Topology. ... Ring Topology. ... Tree Topology. |
| Star Topology: Advantages and Disadvantages. In Star topology, all the components of network are connected to the central device called “hub” which may be a hub, a router or a switch. ... So it can be said that every computer is indirectly connected to every other node by the help of “hub”. |
