A Point of Pr

A Point of Presence (PoP) is an access point in the network where Internet Service Providers (ISPs), telecommunications, and other service providers establish connections to offer services to end users and businesses, acting as a traffic and service distribution node.

What is a PoP?

A PoP is a physical location that:

  • **Connects users" with service providers
