If you want to create a home network and want the greatest flexibility in where to locate various computers and other connected equipment around your house, which transmission media provides the most flexibility and least installation effort.-wireless radio waves -coaxial cable -Telephone line -Fiber optic cable If you want to create a home network and want the greatest flexibility in where to locate various computers and other connected equipment around your house, which transmission media provides the most flexibility and least installation effort.
-wireless radio waves -coaxial cable -Telephone line -Fiber optic cable
-wireless radio waves -coaxial cable -Telephone line -Fiber optic cable
Explanation / Answer
1. Wire is somewhat less secure as it can be tapped without breaking the connection, and can also be monitored without a physical connection (with some effort).
2. Wireless is the least secure since whether it is point-to-point or omni-directional, the signal is easily accessible to many people.
3. Again, this is a high level assessment. There are factors that can increase or reduce the security of each medium, many of those stemming from the implementation of the technology.
4. The following are transmission media.
-wireless radio waves
-coaxial cable
-Telephone line
-Fiber optic cable
A) Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor.
- The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It is not flexible.
B)Coaxial cables are a type of cable that is used by cable TV and that is common for data communications. Taking a a round cross-section of the cable, one would find a single center solid wire symmetrically surrounded by a braided or foil conductor. Between the center wire and foil is a insulating dialectric. It is not flexible for our requirement.
C)A telephone line or telephone circuit (or just line or circuit within the industry) is a single-user circuit on a telephone communication system. This is the physical wire or other signaling medium connecting the user's telephone apparatus to the telecommunications network, and usually also implies a single telephone number for billing purposes reserved for that user. It is not flexible for our requirement.
D)
-An optical fiber cable is a cable containing one or more optical fibers that are used to carry light.
-The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed.
-Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building.
-Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymeror polyimide.
-Therefore it is most flexible transmission media in the network.
