Flag sequence: In data transmission or processing, a sequence of bits used to delimit, i.e. mark the beginning and end of a frame.
Note 1: An 8-bit sequence is usually used as the flag sequence; for example, the 8-bit flag sequence 01111110.
Note 2: Flag sequences are used in bit-oriented protocols, such as Advanced Data Communication Control Procedures (ADCCP), Synchronous Data Link Control (SDLC), and High-Level Data Link Control (HDLC).
Famous quotes containing the words flag and/or sequence:
“By the rude bridge that arched the flood,
Their flag to April’s breeze unfurled,
Here once the embattled farmers stood
And fired the shot heard round the world.”
—Ralph Waldo Emerson (1803–1882)
“It isn’t that you subordinate your ideas to the force of the facts in autobiography but that you construct a sequence of stories to bind up the facts with a persuasive hypothesis that unravels your history’s meaning.”
—Philip Roth (b. 1933)
