I am starting out in IT and am about to complete A+ cert course. I understand that TCP/IP is a foundation element of the internet and is implemented with many other protocols. I would like to know exactly what it’s function is tho. What does it do, how long has it been around, and how it work in tandem with other protocols? I’ve tried researching it but always end up reading a bunch of high level tech jargon.

If you think of the information as a letter being sent the application drafts the letter and then it get’s all packed up and ready to send but you need to know where it is going. TCP/IP is essentially the address and return address information and then DNS allows names to be converted to the numbers etc.
