What is the transmission media on which data instructions or information travels?
communication channel
What is packet oriented data service?
A method of data transmission in which small blocks of data are transmitted rapidly over a channel dedicated to the connection only for the duration of the packet's transmission.
What communications is a transmission media on which data instructions or information travel?
Communication channel
What data transmission speed is needed for one voice channel?
09. A tuned RF amplifier is
What is channel matrix?
A channel state matrix can provide the information needed to determine whether spatial multiplexing is possible for multilayer data transmission. Simple indicators for evaluating the mobile radio channel are derived from the channel matrix
What are key factors that can affect channel capacity?
Channel capacity - It is the rate at which the data can be transmitted over a given path, or channel, under the given conditions. Key factors affecting the channel capacity are- Data rate- speed of data transmission measured in bits per second. Bandwidth – Maximum. Bandwidth, noise, and error rate.
What is the purpose of the transmission?
Transmission is used to send data from one place to the other. It is a means of communication, which uses a transmitter to send out information through a communication channel.
What is the diffrance between source coder and channel coder?
actually the channel coding is used for the security of transmission of any digital data. and it also determines the appropriate channel for the tranmission of your message on internet
What is often meant by the term 'data transmission'?
A transfer of data from point-to-point is simplified as data transmission. Data transmission can be referred to as digital communication but can include analog data transmission as well.
What is data communications and what four items are needed to make it work?
Data Communication is the transmission of data (text, voice, etc) from one computer to another (or to a peripheral device). The four things needed are a sender, a receiver, a channel and a protocol.
Suppose transmission channels become virtually error free.Is the data link layer still needed?
The data link layer is still needed for flow control over the transmission channel and for framing the data. In a multiple access medium such as a LAN, the data link layer is required to coordinate access to the shared medium among the multiple users.
What transmission is data sent in a constant stream of frames?
synchronous transmission. In a asynchronous transmission, data is sent as individual data bytes
