Fiber Optic Cable
A fiber optic cable is made of glass or plastic and transmits signals in the form of light pulses. An optical fiber is a thin flexible medium conducts pulses of light with each pulse representing a bit. A single optical fiber can support tremendous bit rates up to tens or even hundred of gigabits per second.
A thin glass fiber is encased in a plastic jacket which allows the fiber to bend without breaking. A transmitter at one end uses light emitting diode ( LED) or laser to send pulses of light down the fiber which are detected at the other end by a light sensitive transistor. Fibe optic cabling consists of a canter core surrounded by several layers of protective materials.
It transmits light rather than electronic signals eliminating teh problem of electrical interference. This make it ideal for certain environments that contain a large amount of electrical interference. It has also made it the standard for connecting networks between buildings due to its immunity to the effects of moisture and lighting
Fiber optic cable has the ability to transmit signals over much longer distances than coaxial and twisted pair. It also has the capability to carry information at vastly greater speeds. This capacity broadens communication possibilities to include services such as video conferencing and interactive services. The cost of fiber optic cabling is similar to copper cabling. However it is more difficult to install and modify.
Retransmission of packets The disadvantage of thronging away a correctly received packet is that the subsequent retransmission of the packet might be lost or garbled and

So for this project, we’re going to make a game. This game will make use of a server to join two clients together for a modified game of Blackjack.
Question: Consider that you have to configure a small WLAN of 8 computers using Wired Equivalent Privacy (WEP) and that you have to best make use of its available security f
introduction
What do you mean by OSI? The Open System Interconnection (OSI) reference model explains how information from a software application in one computer moves by a network medium to
10Base2 an Ethernet term meaning a maximum transmitting rate of 10 Megabits per second that uses baseband signaling, with a contiguous cable segment length of 200 meters (185mts).
When the signal hits to each other, collision accord.
Hardware difficulty It refers to the price of hardware logic like connectors, wires, switches, arbiter etc. that are required for execution of interconnection network.
