How is communication possible without a physical medium?
An unguided transmission transmits the electromagnetic waves without using any physical medium. Therefore it is also known as wireless transmission. In unguided media, air is the media through which the electromagnetic energy can flow easily.
What is the role of transmission medium in a network?
Transmission media is a communication channel that carries the information from the sender to the receiver. Data is transmitted through the electromagnetic signals. The main functionality of the transmission media is to carry the information in the form of bits through LAN(Local Area Network).
What is the most common medium used in homes and businesses?
Class B IP addresses are used for medium and large-sized networks in enterprises and organizations. They support up to 65,000 hosts on 16,000 individual networks. Class C addresses are most common and used in small business and home networks.
What are the different types of transmission medium?
Transmission Media is broadly classified into the following types:
- Guided Media: It is also referred to as Wired or Bounded transmission media.
- (i) Twisted Pair Cable –
- (ii) Coaxial Cable –
- (iii) Optical Fibre Cable –
- (iv) Stripline.
- (v) Microstripline.
- Unguided Media:
- (i) Radiowaves –
Which transmission media is the most expensive?
The optical fibre cable made up of glass is the most expensive one among all the transmission media.
Which transmission media is best and why?
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 type of transmission media is the least expensive to manufacture?
The three guided media commonly used for data transmission are twisted pair, coaxial cable, and optical fiber (Figure 4.2). We examine each of these in turn. The least expensive and most widely used guided transmission medium is twisted pair.
Which cable can carry signals of higher frequency ranges than which cable?

| 43. | ______ cables carry data signals in the form of light. |
|---|---|
| a. | Coaxial |
| b. | Fiber-optic |

| d. | none of the above |
How transmission media is divided into groups?
Transmission media can be divided into two broad categories : Guided and Unguided. Guided media, which are those that provide a conduit from one device to another, include twisted-pair cable, coaxial cable, and fiber-optic cable. Guided Media is also known as Bound Media.
Which transmission media has the largest bandwidth?
Fiber optics—Fiber offers enormous bandwidth, immunity to many types of interference and noise, and improved security. Therefore, fiber provides very clear communications and a relatively noise-free environment.
Which transmission media is more immune to tapping?
Light weight: Fiber-optic cables are much lighter than copper cables. Greater immunity to tapping: Fiber-optic cables are more immune to tapping than copper cables. Copper cables create antenna effects that can easily be tapped. Disadvantages: There are some disadvantages in the use of optical fiber.
Which type of medium is best for a data network?
Coaxial Cable Offering better data rates and less signal attenuation, a coaxial cable consist of a central copper conductor that is surrounded by a foil shield. The foil is covered by yet another shield known as a braided shield. Unlike twisted pairs, coaxial cables only have a single copper conductor.
What is the slowest Internet?
