What is TCP/IP?
Transmission Control Protocol or TCP ensures your data is transferred correctly between computers, such as when you send a request to see a web page on the Internet or when you send email to a co-worker on your company's computer network. Internet Protocol or IP is responsible for moving that data between computers. TCP/IP work together to help you communicate effectively and efficiently online, so in order to make that happen you must first set it up on your computer.
What is an IP address?
An Internet Protocol address or IP is the set of numbers that identify your computer to other computers, such as a network printer at your job, or any computer connected to the Internet. IP version 4 (IPv4) is represented by four groups of numbers separated by periods, such as 123.53.789.10. Since IPv4 addresses are running out, IP version 6 (IPv6) was developed. IPv6 is represented by eight groups of four hexadecimal digits separated by colons.
