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...

15. Calculate the total number of bits transferred if 200 pages of ASCIIl data are sent using asynchronous serial data transfer. Assume a data size of 8 bits, I stop bit, and no parity. Assume each page has 80x25 of text characters. 16. In Problem 15, how long will the data transfer take if the baud rate is 9.600?

A common measure of transmission for digital data is the baud rate, defined as the number of bits transmitted per second. Generally, packet transmission consists of a start bit, a byte of information, and a stop bit. How long would it take to transmit a 5"x7" picture with a resolution of 300 pixels/inch with 256 levels per pixel and a compression ratio of 2.625 using a: 1. 2. 3. 4. 9.6K baud modem-released in 1984? 56K baud modem - released...

Suppose an 802.11b station is configured to always reserve the channel with the RTS/CTS sequence. We assume a frame without data is 35 bytes long, and the transmission rate is 10 Mbps. Suppose this station suddenly wants to transmit 500 bytes of data, and all other stations are idle at this time. As a function of SIFS and DIFS, and ignoring propagation delay and assuming no bit errors, calculate the time required to transmit the frame and receive the acknowledgement....
