Fiber optic cable has bandwidth more than 2 gbps (Gigabytes per Second) Characteristics Of Fiber Optic Cable: Expensive Very hard to install Capable of extremely high speed Extremely low attenuation No EMI interference Advantages Of Fiber Optic Cable: Fast Low attenuation No EMI interference Disadvantages Fiber Optics: Very costly Hard to install IP address An identifier for a computer or device on a TCP/IP network . Networks using the TCP/IP protocol route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address. Within an isolated network, you can assign IP addresses at random as long as each one is unique. However, connecting a private network to the Internet requires using registered IP addresses (called Internet addresses ) to avoid duplicates. The four numbers in an IP address are used in different ways to identify a particular network and a host on that network. Four regional Internet registries -- ARIN , RIPE NCC , LACNIC and APNIC -- assign Internet addresses from the following three classes. Class A - supports 16 million hosts on each of 126 networks Class B - supports 65,000 hosts on each of 16,000 networks Class C - supports 254 hosts on each of 2 million networks The number of unassigned Internet addresses is running out, so a new classless scheme called CIDR is gradually replacing the system based on classes A, B, and C and is tied to adoption of IPv6 .

MAC address Short for Media Access Control address, a hardware address that uniquely identifies each node of a network . In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sub-layers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium. Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address. How to Find a MAC Address To display your MAC address on a Windows NT/2000/2003/XP/Visa computer : Click START Go to ACCESSORIES Select Command Prompt Type: (no quotes) "ipconfig /all" In the "ipconfig /all" results look for the adapter you want to find the MAC address of. The MAC address is the number located next to "Physical Address" in the list. See "What Is a MAC Address?" in Webopedia's Quick Reference section to learn how to find a MAC address, identifying unknown devices and more. Also see a breakdown of the seven OSI layers in the Quick Reference section of Webopedia.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
