- 1DESCRIPTION OF PACKET SWITCHINGThis is the process of data being broken down into 'packets' before before being sent through a network and then reassembled at the other end.
- 2ADVANTAGES OF PACKET SWITCHINGThey are:
- Sends data across a network efficiently.
- It means big files which would otherwise clog up the network, can be sent whole.
- Allows efficient movement of data through a network because small packets can choose different routes through the network.
there is a security benefit because if a a packet is intercepted, the hacker will only have one part of the whole file. - 3DISADVANTAGES OF PACKET SWITCHINGThey are:
- If one or more packets are lost or corrupted during the transmission the file will no t be received correctly.
- Requires a large amount of RAM (Random Access Memory) to handle large amount of data communication in packets. - 4CODECSVoIP uses CODECS at either end to encode or decode data. The sender's computer records a message using a webcam and microphone.
