Math.sin (Math.PI) returns

transmission is more complex than wired transmission because it incorporates more detection/correction and security methods 88. distortion creates echoes that blur or smear signal content, increasing the error rate 89. In half-duplex mode after sending a message, the first node signals its intent to cease transmission by sending a special control message called a(n) 90. mode allows the receiver to request retransmitting a message if it detects errors 91 transmission uses only a single transmission line and a return wire. 92. Packet switching, the most common type of TDM, divides messages from all users or applications into small pieces called transmission ensures that sender and receiver clocks are always synchronized by sending 93. continuous data streams. transmission, messages are sent on an as-needed basis 94. In parity, the sender sets the parity bit to O if the count of I-valued data bits is even or to 95. Under 1 if the count of 1-valued data bits is odd. data? manipulated to represent What are the three characteristics of sine waves that can be
