Basically Its a transmission system that sends packets of data across a link and then waits until it has received signals back from the recipient to show successful transmission of all data packets in that window (set size of a number of data packets). Any packets that don't receive a successful transmission flag are resent before the window progresses to the next set of data packets.
If we are sending a file in one go and if some error occurred in between the file transfer then the complete file has to be resend which wastes the bandwidth so to prevent this, the file to send is divided in to smaller unit which we call packet, and then send packets 1 by one so that if a packet is lost then we need to send only that particular packet not the complete file.

The basics of how modems work is the same in how a network itself works. When you view a website there is a lot that happens behind the scene. Your computer sends data in packets to your ISP's server which translates the information and pushes your connection to the website you want. The website which is another server puts the packets together and takes that information that you asked of it (say you clicked a link on the website to go to the next page) and sends the information of the next page to your ISP's server then from there back to you. As it transmits in between its in data packets and becomes a file again at the other end.
