Understanding T1 in Networking: Latency and Propagation Delay

T1 is the time it takes for a pulse to travel from the transmitter to the receiver. It is also known as the "latency" or "propagation delay". In other words, it is the time it takes for the signal to propagate through the medium.

For example, if you are using a wired Ethernet connection, T1 is the time it takes for the electrical signal to travel from your computer to the router and back. If you are using a wireless network, T1 is the time it takes for the radio wave to travel from your computer to the access point and back.

T1 is an important parameter in networking because it can affect the performance of your network. For example, if T1 is too long, it can cause delays in data transmission, which can lead to poor network performance. On the other hand, if T1 is too short, it can cause packet loss or corruption, which can also lead to poor network performance.

In general, T1 is typically measured in milliseconds (ms) and is usually less than 10 ms for a wired Ethernet connection and less than 50 ms for a wireless network.
