What else can I help you with?
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 amount of data transmitted on a transmission medium over a period of time?
The amount of data transmitted on a transmission medium over a period of time is referred to as bandwidth. It is typically measured in bits per second (bps) and indicates the maximum data transfer rate of that medium. Higher bandwidth allows for more data to be transmitted concurrently, improving the efficiency and speed of communication. Factors such as network congestion, signal quality, and technology used can affect the actual data transmission rate.
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
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as?
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as multiplexing
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
Which is a line of sight communication medium?
Optical fibers are a line of sight communication medium that transmit data using light signals that travel straight along the fiber. They are commonly used in telecommunications and internet services for high-speed data transmission.
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.
