Physical Layer
Q2.
What is the maximum number of characters (7 bits + parity) that can be transmitted in a second on a 19.2 Kbps line. This asynchronous transmission requires 1 start bit and 1 stop bit.Q4.
In the Ethernet, which field is actually added at the physical layer and is not part of the frame.Q5.
By using an eight bit optical encoder the degree of resolution that can be obtained is (approximately)Q7.
Assume that each character code consists of 8 bits. The number of characters that can be transmitted per second through an asynchronous serial line at 2400 baud rate, and with two stop bits isQ9.
If there are n devices (nodes) in a network, what is the number of cable links required for a fully connected mesh and a star topology respectivelyQ10.
Data is transmitted continuously at 2.048 Mbps rate for 10 hours and received 512 bits errors. What is the bit error rate?
