Why very low frequencies are not used for data transmission in computer network?

Waves of very low frequency are not used for data transmission in computer networks because they may attenuate and fail to transmit data. However, sometimes such low frequency waves may be used if repeaters are installed along the transmission route.

∙ 15y agoLow frequency radio signals can be used for data transmission, but only at a very low baud rate. That makes them "too slow" to be really effective. For instance, at 30 MHz, the fastest baud rate that can be used is about 300 baud. If a higher baud rate is used, some of the pulses of the RF signal can be seen by the receiver as data bits (and they are not). That will cause a CRC error. In the second place, low frequency transmitters are more complicated to design than VHF or UHF transmitters. A 433.92 MHz transmitter can handle baud rates of up to 9600 baud and can be manufactured on a very small PCB.

What is encoding or scrambling data for transmission across a network called?
Encryption
What controls the flow of data between the computer and network cable?
The Network Interface Card (NIC) or modem (Dial-up) controls the flow of data between your computer and the cable.
Personal computer vs network computer?
Personal Computer is the computer that is not connected unto any other computer. Network Computer are computers that are inter-connected with each others. Network Computer can access any other computers files/data from one another.
What is a network standard that specifies no central computer or device on the network should control when data can be transmitted?
Ethernet.
What hardware inisde a personal computer provides the ability to acess data transmitted over a network?
To access a network, some type of network card must be installed in the computer.
Why low frequencies are not used for data transmission in computer networks?
Low frequencies are avoided for data transmission in computer networks to prevent data loss due to attenuation of the signal. Also, low frequencies are incapable of transferring data at the speeds of higher frequencies.
What is computer networks frame?
a frame in computer network, is a digital data transmission unit.
What is transmission bandwidth?
The frequencies which are used to transmit data.
What is mutlicast?
Perhaps you mean multicast? Multicast refers to computer networking, and is the simultaneous transmission of data to several destinations on a network.
What is Computer network Polling?
Computer network Polling is where a client server or Network Hub polls each computer for data. Data can only be sent when the particular computer is polled. If the computer has data to send but is not polled at that time, the data has to be stored until it can be sent. ^_^ JunkCollector ^_^
What is transmission network?
Transmission media is a device which is used to transfer the data between one computer to another computer.There are two types of Transmission media: 1. Guided Media 2. Unguided Media
What is the purpose of electronic data exchange?
Large corporations uses electronic data exchange (EDI) for the transmission of data between different computer networks. For example, an online purchase is made and the order then goes through the computer network for complete processing.
What has the author Tracey Ho written?

What is network terminal?
A computer that is used to access data on a network
A computer on a network that acts as the central storage location for programs and data used on the network is what?
A computer on a network that acts as the central storage location for programs and data used on a network is a server.
What is the Computer on a network that acts as a central storage location for programs and data used on the network?
