Su, Andy – Homework 10 – Due: Nov 27 2007, 11:00 pm – Inst: Valvano 1 This print-out should have 7 questions. Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. The due time is Central time. Homework 10 001 (part 1 oF 1) 10 points A serial port is confgured 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 confgured 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 specifcations 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? Correct answer: 19200 bits / sec.
