RTT is the acronym for Round Trip Time, a metric used to measure the time it takes for a data packet to travel from a server to a client and back again. It is an essential component of network latency and can have a significant impact on internet speed and application performance. Synonyms for RTT include latency, response time, ping, and round-trip delay. These terms are all used interchangeably to refer to the time it takes for data to be transmitted between two points over a network. Knowing the RTT of a network connection is crucial for network administrators and technicians to ensure smooth operation and optimal performance.
