Answer:
Packets.
Step-by-step explanation:
A data packet is a unit of data carried by a packet-switched network. Data Packets are transmitted along a given network path. Data travels across internet in packets. A packet can carry 1,500 bytes maximum. A packet contains a header and a footer which tells computers what type of data is in the packet, whats the source and destination of the data.
Transmission control protocol and internet protocol is a collection of communication protocols that for sending and receiving date using internet. TCP breaks the data into packets and maintains the network connection and IP deals with the sending and receiving packets from one computer to other using a process called IP Routing which determines the path for the packets to follow from one computer to the other. Once the packets reach their destination, TCP reforms them into their original state.
