    Q1.Which cable is considered a broadband communication channel?
    Ans:-
    a.coaxial cable
    b.Fiber optics cable
    c.Microwave circuits


    Q2.What are the categories of Transmission media?
    Ans:-
    A.Guided media
    i.Twisted pair cable
    1) shielded TP
    2) Unshielded TP
    ii.Coaxial Cable
    iii.Fiber optic cable
    B.Unguided Media
    i.Terrestrial microwave
    ii.satellite communication


    Q3.What is cladding?
    Ans:-
    A layer of a glass surrounding the centre fiber of glass inside a fiber optic cable.


    Q4.Which transmission media has the highest transmission speed in a network?
    Ans:-
    Optical fiber transmission media has the highest transmission speed in a network.


    Q5.what is difference between Step Index Fiber and Graded Index Fiber?
    Ans:-
    Step Index Fiber is a fiber in which the core is of a uniform refractive index and there is a decrease in the index of refraction athe the cladding.
    Graded Index Fiber is a type of fiber where the refractive index of the core is lower toward the outside of the fiber.It bends the rays inward and also allows them to travel faster in the lower index of refraction region.This thpe of fiber provides high bandwidth capabilities.


    Q6.What are the types of wireless transmission? Also mention it's range
    Ans:-
    a.Radio Wave
    -range of about 3KHz to 1GHz
    b.Microwave Transmission
    -range of about 1GHz to 300GHz
    c.Infrared
    -range of about 300GHz to 400THz



    Q7.what are the three modes of propagation of electromagnetic waves?
    Ans:-
    1)Ground Propagation:
    The low frequency waves travel through the atmosphere closest to the earth's surface.
    2)Sky propagation:
    The high frequency waves travel upwards into the ionosphere and are reflected back.
    3)Line-of-sight Propagation:
    This signals are very high frequency waves and are transmitted in a straight line from the source antenna to the receiving antenna.



    Q8.what is straight through cable and crossover cable?
    Ans:-

    Straight through cable:
    A straight through cable is a type of twisted pair cable that is used in local area network to connect a computer to a network hub such as a router.

    Crossover Cable:
    A crossover cable is a type of cable installation that is used for the interconnection of two similar devices.
