Data Transmission – Large Amounts of Data

In Information technology, units of data that are being transferred over a computer network can be referred to as Packets. When a large amount of data is being sent, the data is split into smaller packets, and when it gets to the receiver (which is the destination address), it is repackaged to its former format.

Routing Facilitates Data transmission

Routing is a process that enables packets of data to be transferred over a network from a source address to a destination address. Identification numbers are allocated to each of the packet. The number allocated is referred to as the IP address, and this number makes it possible for the receiver to put the packets of data back into its original state.  If an error occurs and one of the packets could not be delivered to the correct address, a NAK (negative acknowledgement) is sent to the source address and the message has to be resent. The routing table is a database of information that stores the destination addresses for packets of data moving over a computer network. Routing tables facilitate the delivery of packets over a network.

Compression

Compression is a technique of data representation that is used to optimise and reduce transfer time across a network. The compression techniques may vary depending on specific applications, but all they do is to reduce the file size.

Flow Control

Flow control is a function performed by communication protocols.  A communication protocol helps to control the flow of data from one end to the other. If the receiving device is not ready to receive data from the sending device due to some on-going computer processes, the receiver can communicate with the sender through the communication protocol, instructing the sender to hold on until it is ready to receive the data.
