Week 3 HW 1. Identify the different types of network media? Twisted-Pair Cable (UTP Cable, STP Cable, RJ-45 Connectors) Coaxial Cable (BNC Connectors) Fiber-Optic Cable Wireless / Air or Free Space 2. Describe the different IEEE standards? IEEE 802.1: Standards related to network management. IEEE 802.2: General standard for the data link layer in the OSI Reference Model. The IEEE divides this layer into two sublayers -- the logical link control (LLC) layer and the media access control (MAC) layer IEEE 802.3: Defines the MAC layer for bus networks that use CSMA/CD IEEE 802.4: Defines the MAC layer for bus networks that use a token bus networks. IEEE 802.5: Defines the MAC layer for token-ring networks. IEEE 802.6: Standard for Metropolitan Area Networks 3. Define the following and identify. a. Twisted Pair Cable - A type of cable that consists of two independently insulated wires twisted around one another. They are twisted together to maintain balance to reduce crosstalk and noise.

Unformatted text preview: b. Coaxial Cable- wire that consists of a center wire wrapped in insulation, then a grounded shield of braided wire. The shield minimizes frequency interference, but because of high attenuation, more repeaters are needed. c. Fiber-Optic – Glass or plastic coated cable that transmits data in the form of light. Requires less repeaters because of less attenuation. 2. Explain the concept of unguided media. This type of media sends/carries signals through the air and can be received by anyone with the appropriate device. The first type of travel is ground propagation, where low frequency signals travel low and parallel to the ground and can lose power depending on how far away the receiver is. Sky propagation is where high frequency signals are sent towards the dense atmosphere and are reflected back to us to be received. In line of sight propagation, the highest-frequencied signals are sent back and forth through antennas in a straight line....

    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.
