Document Summary

The internet connects uniquely numbered computing devices that relay information from point to point using internet protocol (ip) which is a protocol that uses a set of rules to send and receive messages at the internet address level. The most common protocol is transmission control protocol (tcp) which is a protocol that uses a set of rules to exchange messages with other internet points at data packet level. The computers were able to communicate with any other computer on the network using an ip address which is a method of addressing every physical device on the internet to enable any device to communicate with any other device. An ip address consists of four 8-bit segments of data. People could not remember the ip addresses of all devices to they created a domain name system which was a method of translating names into ip addresses.
