Multiple-choice questions may continue on the next column or page find all choices before answering. The due time is Central time. Homework 10 001 (part 1 of 1) 10 points A serial port is configured to run at a baud rate of 4800 bits / sec. The protocol is 8 bit data, 1 stop, and no parity. What is the bandwidth of this port in bytes/sec? Correct answer: 480 bytes / sec. Explanation: Each frame has 1 start bit, 8 data bits, and 1 stop bit. Since there is one byte trans- mitted for each 10 bits, the bandwidth is 4800 bits / sec divided by 10 bits/byte, which equals 480 bytes / sec. 002 (part 1 of 1) 0 points A serial port can be configured to run at any of the standard baud rates of 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 bits/sec. The protocol is 8 bit data, 1 stop, and no parity. The specifications require that the system be able to transmit data with a bandwidth up to 1800 bytes / sec. In order to be able to pass information at this rate, you have to initialize the serial channel to operate at a bandwidth faster than 1800 bytes / sec. What is the slowest allowable baud rate for this serial port in bits/sec?...
