If several inputs or outputs are waiting for transmission, CPU sends blocks in the most-efficient way {message switching} {block switching}.
Binary messages can split into sections and recombine many times, using methods {Data Encryption Standard} (DES) encoded in 56-bit keys. Methods can use three different keys {triple DES}.
Data can separate into small chunks, travel in pieces through different channels, and then reassemble {multiplexing, data}|.
Message can split into parts that take alternate routes and then recombine at delivery {packet switching}|. In modems, packets are strings of 8-bit bytes, each with start and stop bit.
Decimal-number input can convert to binary numbers {packing, data} {data, packing}. Binary numbers can convert to decimal-number output {unpacking}.
Data can travel on carrier frequencies by AM or FM, or data can be in pulses {ultrawideband}| (UWB).
