Answer:
For one character 8 bits are necessary and 1 stub bit
For one page 80X25 characters are present
Means for one page 80*25 = 2000 characters
For one page
Total no of bits = 2000*8 +2000
=18000 bits
For 200 pages
Total no of bits = 18000*200
=3600000 bits are transferred
Please explain! 15. Calculate the total number of bits transferred if 200 pages of ASCIIl data...
Assume that an asynchronous serial communication protocol is configured to utilize 15-bit data, odd parity, one start bit, one and a half stop bits, and a baud rate of 100kHz. If you were to send 200,000 data frames using the aforementioned protocol, precisely how long should this take, assuming any extraneous communication overhead is negligible?
4. If an asynchronous frame is used to send ASCII characters in the form of bytes (8 bits), what is the shortest time it could take to send 1000 characters if each bit in a frame is 1 msec long? 5. Suppose an asynchronous frame holds 8 bits of data, a parity bit, and two stop bits (it could happen). Calculate the efficiency of the communication system. Suppose a synchronous frame has 16 bits of non-data in the front and...

6. Suppose that an MC68681 is configured to transmit and receive data at 1200 baud, with 7 data bits, odd parity, and 1 stop bit. How long does it take to fully transmit or receive a character? How long would it take to transmit 1024 characters?
Explain with the aid of a diagram how the start, data, parity and stop bits are arranged in a serial word. Should the stop bit be pulled high or low?
1. How many different characters could be encoded using a six-bit code? 2. What is the numerical difference between ASCI a and ASClI 'AN if you treaj them as hexadecimal (hex) numbers? 3. The ASCII codes for the characters 'O' through '9' are what hex numbers? If an asynchronous frame is used to send ASCII characters in the form of bytes (8 bits), what is the shortest time it could take to send 1000 characters if each bit in a...
1. (ch.7) A PCM/TDM system multiplexes 24 voice band channels. Each sample is encoded into 7 bits and a frame consists of one sample from each channel. A framing bit is added to each frame. The sampling rate is 9000 samples/sec. What is the line speed in bits per second? 2. (ch.9) An asynchronous protocol uses 1 start bit, 7 data bits, 2 stop bits and 1 even parity bit for each character. a. How many bits are in a...
Question 3 Link Utilization (15 points) For a Ikm wired link, the data rate is 12Mbits/s and an idle AQR scheme is adopted. 1) If packets are sent in the size of N 2048 bits, calculate the link utilization efficiency where P, 1.1 x 10 2) Assume chanel becomes better resulting in a P, 1 x 10-6. To keep the same link utilization, how can you adjust the data rate, Ri, while keeping the packet length, N, as the same...
help with computer network questions 1. What is the difference between circuit switching and packet switching? 2. What are the different layers in today’s Internet? Why do we create layers? 3. Suppose there is a 10 Mbps microwave link between a geostationary satellite and its base station on Earth. Every minute the satellite takes a digital photo and sends it to the base station. Assume a propagation speed of 2.4 * 10^8 meters/sec. a. What is the propagation delay of...
I NEED HELP WITH DEBUGGING A C PROGRAM! PLEASE HEAR ME
OUT AND READ THIS. I just have to explain a lot so you understand
how the program should work.
In C programming, write a simple program to
take a text file as input and encrypt/decrypt it by reading the
text bit by bit, and swap the bits if it is specified by the first
line of the text file to do so (will explain below, and please let
me...
Please Answer all Questions on Networks, They all involve calculation ( 1-9 Questions) "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second...
