The TCP protocolis a (1) layer protocol. Each connection connects two TCPs that may be just one physical network apart or located on opposite sides ofthe globe. In other words, each connection creates a (2) witha length that may be totally different from another path created by another connection. This means that TCP cannot use the same retransmission time for all connections. Selecting afixed retransnussion time for all connections can result in serious consequences. Ifthe retransmission time does not allow enough time for a (3) to reach the destination and an acknowledgment to reach the source, it can result in retransmission of segments that are still on the way. Conversely, if the retransnussion time is longer than necessary for a short path, it may result in delay for the application programs.Even for one single connection, the retransmission time should not be fixed.A connection may be able to send segments and receive (4)faster during nontraffic period than during congested periods. TCP uses the dynamic retransmission time,a transmission time is different for each connection and which may be changed during the same connection. Retransmission time can be made(5)  by basing it on the round-trip time (RTT). Several formulas are used for this purpose.

The "main storage" normally means that part of internal storage into which instructions and other data must be loaded for subsequent execution or processing. In large computing systems, the term "main storage" is(71) to "memory". "Buffer" mainly indicates a special-purpose storage or storage area allowing, through(72) storage, the data transfer between two functional units having different transfer characteristics. A buffer storage is used between non-synchronized devices or where one is(73) and the other is parallel or between those having different trans far rates. "(74) (memory)" is also a special-purpose buffer storage, smaller and faster than main storage, used to hold a copy of instructions and data obtained from main storage and likely to be needed next by the processor. "Register" is commonly composed of a part of internal storage having a specified storage(75) and usually intended for a specific purpose.
