Data Packet
A data packet is a unit of data transmitted over a network, typically consisting of a header and a payload, which contains the actual data being sent. The header includes control information such as source and destination addresses, Sequence number, and Error-checking data. Data packets are used in various Network protocols, including Internet Protocol (IP) and Transmission Control Protocol (TCP), to ensure reliable and efficient data transfer. The process of dividing data into packets is known as Packetization, and it allows for efficient transmission of data over networks, including the Internet. Routers and Switches play a crucial role in directing data packets to their destination. Understanding data packets is essential for Computer networking and Cybersecurity.
