Final answer:
TCP is a protocol used for reliable data transmission between devices. It divides data into chunks, adds a TCP header, and ensures error-free transmission.
Step-by-step explanation:
TCP, which stands for Transmission Control Protocol, is a protocol used for reliable data transmission between devices. It ensures that data is sent properly by establishing a connection between the client and server and acknowledging the receipt of all data. When sending data, TCP divides it into chunks and adds a TCP header, creating a TCP segment or packet. This process allows for efficient and error-free data transmission.
For example, imagine you are sending a large file over the internet. TCP would break the file into smaller chunks, add a TCP header to each chunk, and transmit them one by one. The receiver would acknowledge the receipt of each chunk, ensuring that all data is successfully transferred.
