The file was encoded, damaged in items and sent by e-mail; the receiver needed to reassemble and decode it later, and it was the only approach for folks dwelling overseas to obtain items corresponding to the sooner Linux versions using the sluggish dial-up connections available at the time.

Kahn had meant that the TCP protocol help a variety of transport companies, from the completely reliable sequenced supply of data (virtual circuit mannequin) to a datagram service by which the application made direct use of the underlying community service, which could indicate occasional lost, corrupted or reordered packets.
