What is transmission medium?
The transmission medium can be defined as a pathway that can transmit information from a sender to a receiver. Transmission media are located below the physical layer and are controlled by the physical layer. Transmission media are also called communication channels. Transmission media are of two types −. Guided Transmission Medium.

What is the difference between coax and unshielded twisted pair?
Coax is another common means of transmission (known to many friends as “coax” and pronounced “coax”). It offers better protection and higher bandwidth than unshielded twisted pairs, allowing it to travel longer distances at higher speeds.
Why are wires twisted?
The wires are twisted in a spiral, like a DNA molecule. Twisting is performed because two parallel cables constitute a thin antenna. When the cables are twisted, the waves of different turns are canceled and the cable radiates less efficiently. As a rule, the signal is transmitted as a voltage difference between two wires of a pair.
Why are twisted pairs used?
Twisted pairs can be used to transmit analog or digital information. The bandwidth depends on the thickness of the cable and the distance traveled, but in many cases, it can reach several megabits per second for several kilometers. Because of their adequate performance and low cost, twisted pairs are widely used and will likely remain so for many years.
What is the role of the physical layer in a computer?
Guided Transmission Media – The role of the physical layer is to transfer bits from one computer to another through the channel. Different physical media can be used for the actual transfer. Each of them has its place in terms of throughput, time, cost and ease of installation and maintenance. Operators are grouped roughly in managed environments, such as copper and fiber optic cables, and in unmanaged environments, such as global wireless networks, satellites, and live lasers.
What is the optical transmission system?
The optical transmission system has three key components: the light source, the transmission medium, and the detector. As a general rule, a light pulse indicates bit 1 and the absence of light indicates bit 0. Ultra-thin fiberglass is the transmission medium. The detector generates an electrical pulse when the light hits it.
What type of cable is used for digital transmission?
Two types of coaxial cables are widely used. One type, a 50-ohm cable, is typically used when it is designed for digital transmission from the start. The other type, a 75-ohm cable, is commonly used for analog transmission and cable television.
What is coaxial cable?
The coaxial cable consists of a hard copper wire surrounded by an insulating material. The insulation is covered with a cylindrical conductor, often similar to a dense woven mesh.
What is the core of a WDM?
The core is surrounded by a less dense glass or plastic covering called the cladding. It is used for the transmission of large volumes of data. The cable can be unidirectional or bidirectional. The WDM (Wavelength Division Multiplexer) supports two modes, namely unidirectional and bidirectional mode.
What is twisted pair cable?
Twisted Pair is of two types: Unshielded Twisted Pair (UTP): This type of cable has the ability to block interference and does not depend on a physical shield for this purpose. It is used for telephonic applications.

What are the factors that affect transmission?
Some factors need to be considered for designing the transmission media: 1 Bandwidth: All the factors are remaining constant, the greater the bandwidth of a medium, the higher the data transmission rate of a signal. 2 Transmission impairment: When the received signal is not identical to the transmitted one due to the transmission impairment. The quality of the signals will get destroyed due to transmission impairment. 3 Interference: An interference is defined as the process of disrupting a signal when it travels over a communication medium on the addition of some unwanted signal.

The characteristics and quality of data transmission are determined by the characteristics of medium and signal.
What is distortion in a signal?
Distortion: Distortion occurs when there is a change in the shape of the signal. This type of distortion is examined from different signals having different frequencies. Each frequency component has its own propagation speed, so they reach at a different time which leads to the delay distortion.
