Cards in this deck (14)
- 1Networka collection of computer and other hardware that has been connected together in order to allow the communication and sharing of resources
- 2Packeta collection of data that is transmitted over a packet-switched network
- 3Routera device that allows communication between a LAN and the Internet. This is the device by which one can access the internet.
- 4Huba device which lots of computer can be connected, usually with Ethernet cables. It allows computers connected to it to communicate with one another.
- 5Switcha device which performs the same function as the hub but it learns the locations of the computer and other devices plugged into it, making the network more efficient.
- 6Network Interface Card (NIC)a device that each computer that is to be added to a network must have. This is where the Ethernet cable would be plugged in, or where the wireless signal would be received.
- 7Protocolan agreed-upon format which allows two devices to communicate
- 8Protocol Stackwhen a programmer takes the rules of a protocol and implements them when creating a program
- 9LAN(Local Area Network)
a network in which the computer systems are all located relatively close to each other
e.g. the same building - 10WAN(Wide Area Network)
a network in which the computer systems are all located relatively distant from each other
e.g. all over a country, different countries - 11Network Topologythe theoretical layout of computer systems on a network
- 12Encryptionthe conversion of data, using an algorithm, into a form called cyphertext that cannot be easily understood by people without the decryption key
- 13Backupthe process of copying data (usually onto a secondary storage medium) so that it can be preserved and restored if the original data is lost
- 14Archivingthe process of storing data which is no longer in current or frequent use
