Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

Coaxial cable has been around since local area networking was in its invented. The original designers of Ethernet picked coaxial cable as their "ether" because the coaxial cable is well it has high bandwidth capabilities and low and is easy to install. Coaxial cables are identified by their RG standard. Coaxial cable can have a or stranded core and impedance of 50, 75, or 92 ohms. The Coaxial has wire that carries the signal surrounded by a layer of and another concentric ; both the shield and the inner conductor run along the same axis. The shield also serves as a ground and should be grounded to be effective. Coaxial cable is still widely used for video applications; in fact, its use is increasing due to the greater demand for However, it is not recommended for data installations and is not recognized by the Standard for such.

a. Assume your university library has a million books. Calculate the number of bytes of data if all of these books were stored online and accessible through a computer network (to the closest order of magnitude). b. How long does it take to transmit the full library of books if the transmission medium's data rate is 10 Mbps, the original Ethernet's speed? If we have a 1 Gbps connection, how long will it take? (The time it takes to download your whole college library is represented by this number.)
