Transmission Control Protocol (TCP)
Transmission Control Protocol (TCP) is the protocol that is responsible for the reliable delivery of messages on the internet. It is imperative to have a general understanding of how the transport layer creates and maintains a connection between two networked systems and how the exchange between the two systems occurs.

Sliding Windows
Data to be transmitted on a network is broken down into smaller packets. These packets are then sent to the destination one packet at a time. Due to the nature of internet routing, some packets may take a different route to the destination. Thus, the receiving system may receive the packets out of order or could even lose some packets.
Sliding windows is the concept of how these packets are sent to the network. The sender doesn’t just send one packet and wait for confirmation of receipt before sending the next packet. Instead, the sender will continuously send packets up to the window size (the amount of data that can be “packed” into a packet before being sent), while also watching for the confirmation message to come in.
