Understanding the Mechanics of the Internet: Coursera Quiz Answers

What is the Internet?

At its core, the internet is a vast network of interconnected computers that communicate with each other using a standardized set of protocols. These protocols allow different devices to share information and resources in a secure and efficient way.

One of the most important protocols on the internet is the Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP is responsible for breaking data into small packets, sending those packets across the network, and reassembling them at their destination. This process ensures that data is delivered accurately and in a timely manner.
