TTCP stands for Test TCP. It is a program that is used to test the speed of data transfer between two computers connected over a TCP/IP network.
Imagine you have a toy car and you want to see how fast it can go from your room to your friend's room across the hall. You could just time it yourself, but that might not be very accurate. So you decide to use a stopwatch to time it. TTCP is like a stopwatch for measuring the speed of data transfer between two computers.
To use TTCP, you need to have two computers connected to the same network. One computer will be the sender and the other will be the receiver. The sender will send data packets to the receiver, and the receiver will measure how long it takes to receive them.
In our toy car example, one person would be the sender and the other person would be the receiver. The sender would drive the car from their room to the friend's room, while the receiver would use the stopwatch to time how long it took.
TTCP is especially useful for testing the speed of networks, because it allows you to measure how much data can be transferred over a network in a given amount of time. This can be helpful for diagnosing network problems and improving network performance.
In conclusion, TTCP is a program that measures the speed of data transfer between two computers connected over a network. It is like a stopwatch for measuring how fast data can travel from one computer to another.
