A 2400 baud, 7 bit word length, odd parity, and one stop bit message transmits characters per second. a) 100 b) 240 c) 440 d) 1000
Homework Answers
Given:
2400 baud, 7-bit word length, odd parity, one stop bit
Answer:
Frame diagram with size:
| Start | Data | Parity | Stop |
| 1 bit | 5-9 bits | 1 bit(either 0 or 1) | 1-2 bits |
2400: maximum of 2400 bits can be transferred per second
7-bit word length: data is being sent in blocks of size 7-bit
Odd parity takes a 1-bit size
Parity is set to 1 if the data bits contain an odd number of 1's, else it is set to 0
The stop bit is used to say that it is the end of the frame. It is of 1-bit in size.
total data to be sent = start bit + data bits + parity bit + stop bit = 1 + 7 + 1 + 1 = 10 bits.
Number of 7-bit word length data bits transmitted per second = 2400/10 = 240
Therefore, the correct option is b) 240
Add Answer to:
A 2400 baud, 7 bit word length, odd parity, and one stop bit
message transmits characters...

Assume that a UART is set for 8-bit transmission with 1 bit of parity, 1 stop bit, and 1 start bit. Assume that the transmission speed was set at 2400 baud. A computer is transmitting data to a monitor a message that consists of 1000 ASCII 8-bit characters. What is the total transmission time of this message? Show your work. (25) 1.

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?

Soru 7 The ASCII code has 128 binary-coded characters. If a computer generates 125,000 characters per second, determine the following: a) The number of bits (binary digits) required per character. b) The number of bits per second required to transmit the computer output, and the minimum bandwidth (Nyquist frequency) required to transmit this signal. c) For single error detection capability, an additional bit (called a parity bit) is added to the code for each character.

Note: b denotes bits and B denotes Bytes (1 Byte = 8 bits). When a node transmits a packet, it doesn’t need to wait for the last packet to be propagated along the link. As soon as one packet is transmitted into the link, the node can start transmitting the next packet Part1: For each of the following cases, calculate the latency (from first bit sent to the last bit received). Assume the bandwidth of each link is 2Gbps, and...
