You pack your house in boxes and put your new address on them.
The moving company picks them up, makes a list of the boxes, and ships them across country along the most efficient route - this may mean putting your dishes and your bedroom furniture on different trucks.
Your belongings arrive at your new address. You consult your list to make sure that everything you shipped has arrived (in good shape), then you unpack your boxes and "reassemble" your house.
TCP/IP is a suite, or family, of protocols that govern the way data is transmitted across networks.
TCP/IP protocols work together to break the data into small pieces that can be efficiently handled by the network, communicate the destination of the data to the network, verify the receipt of the data on the other end of the transmission, and reconstruct the data in its original form.
