Maximum Transmission Unit

Maximum Transmission Unit (MTU) is the largest size of data packet that a network can handle in a single transmission without fragmentation. Think of it as the maximum size of a parcel you can send through a specific mailing service. If your data packet exceeds this size, it may need to be broken into smaller pieces to travel efficiently or successfully across the network. Knowing the MTU helps ensure smooth, efficient data transfer and can prevent problems like delays or failed communication between devices. It varies depending on the type of network or connection used.
