Solution

The correct option is C 12,000 bytes
Number of bits neededto send 1 byte of data =8+1+1+2=12 bits

Baud rate = 9600 bps = 800 char/sec
Hence, 800 bytes are sent in 1 sec.
$in 15 sec = 15 \times 800 = 12, 000 b y t e s$
Note : In given Question I start bit is miss which is always present in asynchronous transmission mode.

Q. How many 8-bit characters can be transmitted per second over a 9600 baud serial communication link using asynchronous mode of transmission with one start bit, eight data bits, and one parity bit and two stop bits?

Q. A serial transmission T1 uses 8 information bits, 2 start bits, 1 stop bit and 1 parity bit for each character. A synchronous transmission T2 uses 3 eight-bit sync characters followed by 30 eight-bit information characters. If the bit rate is 1200 bits/second in both cases, what are the transfer rates of T1 and T2 ?

Q. Consider a parity check code with three data bits and four parity check bits. Three of the code words are 0101011, 1001101 and 1110001.

Which of the following are also code words?

Q. Consider three networks A,B and C. Host

H_{A}

in network A sends messages each containing 180 bytes of application data to a host

H_{C}

in network C. The TCP layer prefixes a 20 byte header to the message. This passes through an intermediate network B. The maximum packet size, including 20 byte IP header, in each network is
A: 1000 bytes
B: 100 bytes
C: 1000 bytes
The network A and B are connected through a 1 Mbps link, while B and C are connected by a 512 Kbps link (bps=bits per second)

Assuming that the packets are correctly delivered, how many bytes, including headers, are delivered to the IP layer at the destination for one application message, in the best case? Consider only data packets.
