5. Data Compression: Data compression techniques can be used to reduce the size of large files before they are transmitted over a network. This helps in saving time and increasing the speed of data transfer.

6. Error Correction Codes: Sometimes, during data transfer, errors may occur due to noise or interference on the network. Error correction codes help in identifying these errors and correcting them, ensuring that the transmitted data is intact and accurate.

7. Quality of Service (QoS): QoS mechanisms prioritize certain types of traffic, such as real-time video conferencing or voice calls, over other types of traffic to ensure that they are given enough bandwidth for smooth communication.

In summary, handling large amounts of data transfer within a network involves several components working together to ensure efficient, reliable, and secure data transfer between systems.
