TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of communication protocols used for interconnecting network devices on the internet. It provides a standardized way for data to be transmitted over networks and ensures that data is transmitted accurately and efficiently.
TCP manages the transmission of data by dividing it into packets, creating a connection between two devices, sending packets in a reliable manner, and retransmitting any lost packets. IP manages the routing of data packets between network devices by assigning unique IP addresses to each device and directing the packets to their destination.
Other protocols in the TCP/IP suite include HTTP (Hypertext Transfer Protocol), which is used for transmitting web pages, FTP (File Transfer Protocol), which is used for transferring files, and SMTP (Simple Mail Transfer Protocol), which is used for sending email messages.
