Unit 4 Assignment 4 Physical Layer Network Concepts Jorge Santana IT22 Network Standards And Protocols Leno Jr, Henry R May 3, 2013 1. You have created a simple electrical circuit with a battery, wires, and a light bulb. Which of the following is true about this circuit? (Choose two.) a.
d. The amplitude is 1 volt. 3. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. Which of the following tasks is a function done by the transmitter? (Choose two answers.)
Unit 8: Assignment 1 There are 3 main factors to consider when you’re about to splice a fiber-optic cable on loss of performance. The first is that optical fibers are not perfect and variations between Optical fibers can affect splice performance. These variations are referred to as intrinsic factors. The performance of a splice can also be affected by alignment and optical fiber mating issues that have nothing to do with the optical fiber. The factors that affect the alignment and/or mating of the optical fibers are referred to as extrinsic factors.
11. Cable Toner12. Continuity Tester- an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made 13. Category 5e/6 cable- is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards 14. Binder Groups- Cable pairs are typically arranged under the cable sheath in binder groups 15.
(Choose two answers.) a,c 3. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. Which of the following tasks is a function done by the transmitter? (Choose two answers.)
Answer: The TCP/IP protocols were initially developed as part of the research network developed by the United States Defense Advanced Research Projects Agency it was created for a number of different protocols but had many flaws and was adapted for more of a business and house hold use Lab 3.2 1 How does the abstraction of the physical layer facilitate interoperability across networks using different types of physical wires? Answer: It is according to the kind of wire and how it is made up of, E.g. Copper Fiber optics. The physical layer includes electrons. The faster this can move back and forth from one point to another, the faster data is transferred, to have proper connection is just as important as the wire themselves to make a smooth transfer.
Figure 2 shows a circuit with a resistor R = 1.0 × 103 Ω, and a battery with potential difference of VB = 5.0V . (a) Solve the circuit in Figure 2. That is, find all unknown currents, voltages, and resistances. (b) What is the direction of the current? Note: I want the direction of the conventional current.
Answer: Here given, Im = 2.53 mA Dividing Amplitude of voltage Im by √2, 2.53 √2 = 1.8 Comment: Both values were not matching. There have more than 10% discrepancy. Q. 3. Calculate the impedance by the measured values of voltage and current from the oscilloscope.
Jose Flores 6th period 1-27-14 LAB REPORT Introduction: A substance can conduct an electrical current if it is made of positively charged and negatively charged particles that are free to move about and is called a conductor. The purpose is to figure out conductivity of substances and to check which one conducts electricity. The hypothesis is that sucrose would be the only one that could not conduct out of the other six solutions. Materials: The materials used in this lab where six solutions , napkins, 2 pairs of gloves, 2 cups (1 cup with distilled water and 1 cup with solid NaCI) and a conductivity meter. The six solutions are sodium chloride, hydrochloric acid, sodium hydroxide, acetic acid, ammonia and sucrose.
