Cable lines means electronic cable, conduit and their appurtenances which distribute television signals or telephone or internet connections. A cable is a thick wire, or a group of wires inside a rubber or plastic covering, which is used to carry electricity or electronic signals. Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types.
An electrical cable is of two or more wires, or conductors, that form a single cable assembly from the wires being twisted, bonded or braided together. With these cables, stranding the wires can produce a more flexible product. This is when twisting or braiding is used within an assembly. Cables can be classified into various categories, depending on their different uses and structures. Some types are coaxial cables, twisted pairs, optical fibers, patch cables, power cables, data cables, etc.
Electrical cables are used to connect two or more devices, enabling the transfer of electrical signals or power from one device to the other. Long-distance communication takes place over undersea communication cables. The term cable derives from the time when the medium for such communications was telegraphs travelling along international submarine communications cables, though over time they have progressed into other formats and pathways.
