Every computer that is connected to the internet is part of a network, which is provided by an internet service provider (ISP). Large communication companies have points of presence (POP), which is a place where local users can access the company's network. There is no overall controlling network; there are several high-level networks connecting through network access points. Networks depend on network access points, backbones, and routers to communicate. Every machine on the internet has a unique identifying number called an IP address. The domain name system was created so IP addresses would not have to be memorized. All machines on the internet are either servers or clients. Servers have static IP addresses that rarely change.
