TTL—

Transistor-Transistor Logic. A form of digital switching that utilizes

bipolar transistors to sense “high” and “low” logic levels (1 and 0,
respectively).

Transmission Latency—

Time required to send a single packet of data to the

receiving end of the circuit. This value will depend on the baud rate and
number of bytes in the sequence.
