Optical fibers are the most secure of all the cable media. Installation and maintenance are difficult and costly. Fiber optic cables have greater transmission speed, high bandwidth, and the signal can travel longer distances when compared to coaxial and twisted pair cables.
Which transmission media is fastest?
Answer: Fiber optics is the fastest of the given data transmission techniques.
What is the most widely used transmission media?
(i) Twisted Pair Cable –
They are the most widely used Transmission Media.
Which guided transmission media is the best and why?
Longer distances: The fibre optic cable carries the data at a longer distance as compared to copper cable. Better reliability: The fibre optic cable is more reliable than the copper cable as it is immune to any temperature changes while it can cause obstruct in the connectivity of copper cable.
Which is better guided or unguided media?
In the unguided media, the signal energy propagates through a wireless medium. The wireless media is used for radio broadcasting in all directions.
|S.No.||Guided Media||Unguided Media|
|1.||The signal energy propagates through wires in guided media.||The signal energy propagates through air in unguided media.|
Which transmission media is least expensive?
The least expensive and most widely used guided transmission medium is twisted pair.
Why guided media is more reliable?
The major advantage of the guided media is that they have got the higher bandwidth range than the unguided media. In the case of the guided media if accidentally a part of the cable gets broken down then it doesn’t affect the whole network system.
Is coaxial cable more expensive than fiber optic cable?
Generally more expensive to install and operate than coaxial cable, fiber offers distinct advantages for businesses with high-volume, digital data networking needs. Fiber networks can provide dedicated access to the Internet with synchronous transfer, meaning that you will get the same speed for uploads or downloads.
Which medium is preferred for transmission?
The most common conductor in use for transmission today is aluminum conductor steel reinforced (ACSR). Also seeing much use is all-aluminum-alloy conductor (AAAC). Aluminum is used because it has about half the weight and lower cost of a comparable resistance copper cable.
Which transmission media are widely used in the backbone of network?
Coaxial cable has, in the past, been used to provide network backbone cable segments. Coaxial cable has largely been replaced in computer networks by optical fibre and twisted pair cable, with fibre used in the network backbone, and twisted pair used to connect workstations to network hubs and switches.
Which wired cable supports the highest frequency?
Coaxial cables are high-frequency transmission cables made up of a single solid copper core that transfers data electrically over the inner conductor. Coax has 80X more transmission capacity than twisted-pair cables.
What radiated media?
Radiated media, or wireless media, do not use physical wires to transmit data. With radiated media, the signal is radiated through the air, water and vacuum of space.
Is satellite communication is a type of guided media?
Answer: Hence, it is true. Explanation: because satellite is a combination type of guided media.
What are the disadvantages of unguided media?
Disadvantages of Microwave transmission:
- Eavesdropping: An eavesdropping creates insecure communication. …
- Out of phase signal: A signal can be moved out of phase by using microwave transmission.
- Susceptible to weather condition: A microwave transmission is susceptible to weather condition.
Is guided media faster than unguided media?
Explanation: Guided media has lesser noise and obstacles in comparison to unguided media, this causes guided media to give a faster rate of data transmission than unguided media.
Is fiber optics and unguided media?
Guided − In guided media, transmitted data travels through cabling system that has a fixed path. For example, copper wires, fibre optic wires, etc. Unguided − In unguided media, transmitted data travels through free space in form of electromagnetic signal. For example, radio waves, lasers, etc.
