Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

Q3.Unless specified otherwise, use the free space propagation speed of light 3x108 m/s to calculate the propagation delay. For numerical calculations, the results must show the appropriate unit. Show me a complete solution NOT THE AI SOLUTION. Consider a digital multimedia transmission system. Separate audio and video coders are used to encode these signals. Audio and video bits are packed in packets together and transmitted over a transmission link. Each packet is 2,000 bytes long, which includes a 48-byte header. The system generates one packet every 40 ms. Calculate the following values:a. The minimum data transmission rate required to support the above system.b. The minimum signal-to-noise ratio (SNR) in dB required to transmit the above audio and video information. Assume a 400-kHz transmission channel bandwidth is used.c.

Data communication systems. The solution time of the problem is 10 minutes. In an FDMA-based multiple access system, each user is assigned an 80 kHz channel for full-duplex communication. There are 1000 channels in total in the system.Depending on the information given above, if the initial frequency of the frequency spectrum used by the FMDA system in one direction is 1000 Mhz, the carrier frequency of the channel belonging to the first user is 1.000.040 KHz.A) False B) True
QUESTION 25 A microwave data link has been designed to operate at 110,000 symbols per second while encoding 14 bits per symbol. The receiving equipment requires at least a 50 dB signal to noise ratio in order to operate without significant error. At least 55 kHz of bandwidth on the transmission channel are required for the attempted system. The data rate of the designed link will be 1.54 Mbps. If the actual signal to noise ratio is 100 dB, the system could support encoding as many as 17 bits per symbol. There is not enough information given to determine the minimum transmission power needed to make sure an acceptable power level arrives at the receiver. Exactly 16,348 different symbols would be needed to support 17 bits per symbol. If the background noise at the receiver is -50 dBm, the receive power will need to be at least 1 dBm.
