What Does Response Time Mean?
Response time, in the context of computer technology, is the elapsed time between an inquiry on a system and the response to that inquiry. Used as a measurement of system performance, response time may refer to service requests in a variety of technologies. Low response times may be critical to successful computing.
Techopedia Explains Response Time
Accounting for time demands made on a computer system can take many different forms. In computer networking, for instance, response times between two systems can be measured and viewed using such commands as ping or traceroute (“tracert” from the Windows command prompt). These diagnostic tools make use of the Internet Control Message Protocol (ICMP).
