What does MTU stand for and what does it specify?

Maximum Throughput Unit, maximum data rate
Maximum Transmission Unit, largest packet size without fragmentation
Minimum Transmission Unit, smallest packet size allowed
Minimum Throughput Unit, minimum data transfer rate

The correct answer is: Maximum Transmission Unit, largest packet size without fragmentation

MTU stands for Maximum Transmission Unit and specifies the largest size of a packet that can be sent over a network without the need for fragmentation. When data is transmitted across a network, it is broken down into packets, and if a packet exceeds the MTU value set for the network, it must be fragmented into smaller packets, which can lead to increased overhead and potential delays in transmission. Understanding MTU is crucial for optimizing network performance and ensuring efficient data transfer. By managing MTU settings appropriately, network administrators can reduce the amount of fragmentation and enhance the overall efficiency of the network's data communication.
