I would then untwist the wires and put them in the correct color order that I need. Then I would flatten out the wires and in one hand hold my RJ-45 connector and then with the other hand feed the wires into the connector. This is usually pretty simple with the way the connectors are made, and they are also usually clear. After I’m sure that the wires are in the connector all the way, and in the right order, I would use a wire crimper to clamp[ the wires securely in to the connector. Coaxial cable- For the COAXIAL CABLE I would do the same first few steps by getting the correct length of cable that I would need.
After lining up the wires to the standard I then trimmed them so they were even and I made sure the outer jacket was inside the RJ-45 connector. I inserted the wires into the RJ-45 connector so they lined up with the proper pins in the connector. I inserted the cable and the RJ-45 connector into the crimping tool and I ensured that the wires did not slip from the pins. I crimped the RJ-45 connector to the cable and then I repeated these steps for the other end of the cable. The last thing that needed to be done was to test the cable to make sure that the cable worked correctly.
b. All Ethernet user devices can be up to 100 meters away (but no farther), while WLAN devices can typically be farther away than 100 meters. 2. IEEE 802.11 standards define a maximum speed for an individual transmission, with some variables that affect 802.11n speeds. Assuming that 802.11n uses the narrower 20-MHz channel and a single stream, which of the following answers matches a particular standard to its maximum bit rate?
NT1310 Unit 6 Assignment 1: Cable Tester The three cable testers I would choose would be the optical loss test set and test kit, the Time-Domain Reflectometers (TDR), and the tone generators. The Optical Loss Test Sets and Test Kits is a useful tool in a lab or for testing patch cables, two separate devices would be needed to test a permanently installed link because you have to connect the light source to one end of the cable and the power meter to the other. You need both an optical power meter and a light source in order to properly install and troubleshoot a fiber-optic network, and you can usually save a good deal of money and effort by purchasing the two together. You will thus be sure to purchase units that both support the wavelengths and power levels you need and that are calibrated for use together. You can purchase the devices together as a single combination unit called an optical loss test set (OLTS) or as separate units in a fiber-optic test kit.
The 10 original stations would need to be fit with 10/100/1000 Mbps NIC's to allow for the higher bandwidth and the new 5 would need to have wireless 802.11g/n NIC's installed as well. What topology and which type of device can be used in the manufacturing area to solve the cabling difficulties? An extended star topology with a logical switch topology would need to be utilized. The manufacturing floor would need to have a wireless solution in order to remove the issue with lack of installation room for wiring. Case Project 3 – 2: What type of topology should be used in this network?
A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. The transmitter uses a simple encoding scheme that uses a higher amplitude to encode 1 and a lower amplitude to encode 0, sending 1 bit in each bit time. The bit rate is 2000 bits per second (2000 bps). Which of the following is true on this circuit? a.
Making the voltage higher would make the receiver electronics more difficult. Exercise 4.1.3: What are some applications of shielded copper cable? Why is the more expensive shielded cable used in these situations? Use your textbook or Internet research to support your answer. Hospitals, security systems, PA & recording studios.
Which of the following is true about what happens when a PC NIC connects to a switch using 100 BASE-T? 10. With a fiber optic cable, the core of the cable, through which light passes, is made of which of the following? 11. Which of the following is the type of transmitter used on a fiber optic link that provides the longest maximum distances?
Sonographers begin by explaining the procedure to the patient and recording any medical history that may be relevant to the condition being viewed. They then select appropriate equipment settings and direct the patient to move into positions that will provide the best view. To perform the exam, sonographers use a transducer, which transmits sound waves in a cone-shaped or rectangle-shaped beam. Although techniques vary by the area being examined, sonographers spread a special gel on the skin to aid the transmission of sound waves. (Bureau of Labor Statistics, 2010) Viewing the screen during the scan, sonographers look for subtle visual cues that contrast healthy areas with unhealthy ones.
