2. BRIEF DESCRIPTION
1.) Coaxial cable is an electrical cable consisting of a round conducting wire, surrounded by an insulating spacer, surrounded by a cylindrical conducting sheath, usually surrounded by a final insulating layer.

3. COAXIAL CABLE

4. 2.) Coaxial cabling is the primary type of cabling used by the cable television industry and is also widely used for computer networks; Such as Ethernet.
3.) Coaxial cables may be rigid or flexible. Rigid types have a solid sheath, while flexible types have a braided sheath, both usually of thin copper wire. The inner insulator, also called the dielectric, has a significant effect on the cable's properties, such as its characteristic impedance and its attenuation. The dielectric may be solid or perforated with air spaces.

5. FEATURE OF DATA TRANSMISSION
1.) The transmission of energy in the line occurs totally through the dielectric inside the cable between the conductors.
2.) Coaxial lines can therefore be bent and twisted (subject to limits) without negative effects, and they can be strapped to conductive supports without inducing unwanted currents in them.

6. ADVANTAGES & DISADVANTAGES
a.) low noise.
b.) high-frequency transmission line.
c.) has much higher bandwidth.
d.) offers greater protection from noise and interference.
e.) has the capacity to transmit information 80 times faster.

7. Disadvantages;
a.) Low security.
b.) Limited range.
c.) High cost of installation.
d.) Coaxial cable is difficult to work with than twisted pair cable.
e.) Rigid.
