What are the latest technologies used as transmission media?
fibre optics cables are used as transmission medium.
Why is selection of suitable transmission medium important in data transmission?
It will determine the speed, reliability and relative security of the transmission.
Mention types of transmitions media that the world today uses?
Electric current is a transmission medium which can be used to transfer data across a wire for example ( copper wires). Radio waves is a transmission medium which can be used to carry data through the air. The above mention mediums are known as data transmission media.
What is the wireless transmission medium that carries data via beams of light through the air?
microwave
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 is defined as the amount of data that can be transmitted across a transmission medium in a certain amount of time?
bandwidth
Which transmission medium should be used to transfer data across two continents at very high speed?
sattelite
What is the difference between data transmission speed and propagation speed?
Data Transmission speed is the number of bits per second that can be transmitted. Propagation speed is the speed at which a signal moves through a medium. Gateway Technical College, Elkhorn WI
What is the means through which data is transmitted and received?
Transmission MediaIt's sent through a network client (Microsoft Client) through a transmission medium (wire or wireless) that travels through the appropriate adapter.
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.
Define transmission medium?
the substance that energy is transfered through. For example when you hear a sound the transmission medium is air.
What transmission is data sent in a constant stream of frames?
synchronous transmission. In a asynchronous transmission, data is sent as individual data bytes
