Network latency can be primarily attributed to which measurement?

Network latency is primarily attributed to DNS lookup time. This is because DNS (Domain Name System) is responsible for translating human-readable domain names into IP addresses that computers use to identify each other on the network. When you make a request to a server, the initial step often involves a DNS lookup, which can introduce significant latency if the DNS server is slow to respond or if there are issues in the resolution process.

Although other factors contribute to the overall response time of an application, such as application cache time, request time, and OnLoad time, they do not directly correspond to the network latency that occurs during the initial stages of establishing a connection and sending requests over the network. Each of these factors may impact the perceived performance of an application, but they do not specifically represent the inherent delays caused by the time taken to resolve a DNS query.
