Networks and communication
Cards in this deck (24)
- 1NetworkA way/method of connecting different computers
- 2LANLocal Area Network is a network of computers that covers a small area, eg a school or college.
- 3WANWide Area Network is a network that spans across a building, buildings or even countries, eg the internet.
- 4WLANA Wireless Local Area Network is a wireless distribution method for two or more devices that use high-frequency radio waves and often include an access point to the Internet
- 5Peer to PeerRelating to networks in which each computer can act as a server for the others, allowing shared access to files and peripherals without the need for a central server
- 6Client-Server NetworkA form of computer networking where the data or web application is hosted on a server and accessed by client computers
- 7NodeA node can be a computer or some other device, such as a printer. Every node has a unique network address
- 8TopologyComputers can be joined together in different ways. Three main network topologies are: bus network, ring network and star network
- 9Bus networkIn a bus network all the workstations, servers and printers are joined to one cable (the bus). At each end of the cable a terminator is fitted to stop signals reflecting back down the bus
- 10Ring networkIn a ring network each device (workstation, server, printer) is connected to other devices, this forms a ring for the signals to travel around. Each packet of data on the network travels in one direction and each device receives each packet in turn until the destination device receives it.
- 11Star networkIn a star network each device on the network has its own cable that connects to a switch or hub. A hub sends every packet of data to every device, whereas a switch only sends a packet of data to the destination device.
- 12SwitchA device for connecting computers and other network capable devices together to form a network
- 13IP(Internet Protocol) addressA 'protocol' is a set of rules for doing something. It is the task of being able to uniquely identify every computer connected to an IP based network
- 14ProtocolIt is a set of rules for doing something
- 15MAC (Media Access Control) addressThis is the unique identifier assigned to a network card or Wi-Fi adapter. The code identifies the card and also the maker of that card
- 16SMTP (Simple Mail Transfer Protocol)Protocol used to send mails
- 17HTTP (Hypertext Transfer Protocol)Protocol used by web pages
- 18PacketThis is a small amount of computer data sent over a network
- 19Domain nameIt is a unique name that identifies a website
- 20DNS (Domain Name System)An Internet service that translates domain names into IP addresses
- 21WWW (World Wide Web)It is a collection of webpages found on this network of computers. Your web browser uses the internet to access the web
- 22Back-upIt is the result of copying or archiving files and folders for the purpose of being able to restore them in case of data loss
- 23MeshIts is a fourth topology,
- 24SwitchIt is a computer networking device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device
