Computer cables are confusing to most users. You may also refer to this guide for ideas on how to hook different devices using commonly available connectors and converters. You can use USB cables to connect most new devices to your computer including flash memory sticks, portable media players, internet modems and digital cameras.
DE is the most accurate common nomenclature under the D-sub specifications: an "E" size D-sub connector, with 15 pins in three rows. In both its modern and original variants, VGA utilizes multiple scan rates , so attached devices such as monitors are multisync by necessity. The VGA interface includes no affordances for hot swapping , the ability to connect or disconnect the output device during operation, although in practice this can be done and usually does not cause damage to the hardware or other problems. Some pins on the connector were also different: pin 9 was keyed by plugging the female connector hole, and four pins carried the monitor ID. There are no standards defining the quality required for each resolution, but higher-quality cables typically contain coaxial wiring and insulation that make them thicker.

Identify Types of Network Cables and Connectors. BRIEF You're expected to know the basic concepts of networking as well as the different types of cabling that can be used. For the latter, you should be able to identify connectors and cables from figures even if those figures are crude line art think shadows appearing in pop-up boxes.
There are three specific types network cables, and the connectors associated with each, that you must know for this exam: fiber, twisted pair, and coaxial. Fiber is the most expensive of the three and can run the longest distance. Twisted pair is commonly used in office settings to connect workstations to hubs or switches. Two common wiring standards are TA and TB. Coaxial cabling is not as popular as it once was, but it's still used with cable television and some legacy networks.
The two most regularly used connectors are F-connectors television cabling and BNC 10Base2, and so on. Fiber-optic cabling is the most expensive type of those discussed for this exam. Although it's an excellent medium, it's often not used because of the cost of implementing it. It has a glass core within a rubber outer coating and uses beams of light rather than electrical signals to relay data. Because light doesn't diminish over distance the way electrical signals do, this cabling can run for distances measured in kilometers with transmission speeds from Mbps up to 1 Gbps higher.
ST is a barrel-shaped connector, whereas SC is squared and easier to connect in small spaces. The LC connector looks similar to SC but adds a flange on the top much like an RJ connector to keep it securely connected. FC connectors may also be used but are not as common. MT-RJ is a popular connector for two fibers in a small form factor. In both cases, the cabling is made up of pairs of wires twisted around each other. UTP offers no shielding hence the name and is the network cabling type most prone to outside interference.
The interference can be from a fluorescent light ballast, electrical motor, or other such source known as electromagnetic interference [EMI] or from wires being too close together and signals jumping across them known as crosstalk , STP adds a foil shield around the twisted wires to protect against EMI. While you need to know STP for the exam, you are not required to have any knowledge of the connectors associated with it.
You must, however, know that most UTP cable uses RJ connectors, which look like telephone connectors RJ but have eight wires instead of four. The number refers to the order in which the wires within the Category 5 cable are terminated and attached to the connector. The signal is identical for both. TA was the first standard, released in Ten years later, in , TB was released. Pin numbers are read left to right, with the connector tab facing down.
Notice that the pin-outs stay the same, and the only difference is in the color coding of the wiring. Note : Mixing cables can cause communication problems on the network. Before installing a network or adding a new component to it, make sure the cable being used is in the correct wiring standard.
Coax is built around a center conductor or core that is used to carry data from point to point. The center conductor has an insulator wrapped around it, a shield over the insulator, and a nonconductive sheath around the shielding. This construction, allows the conducting core to be relatively free from outside interference. The shielding also prevents the conducting core from emanating signals externally from the cable.
Note : Before you read any further, accept the fact that the odds are incredibly slim that you will ever need to know about coax for a new installation in the real world with the possible exception of RG-6, which is used from the wall to cable modem. If you do come across it, it will be in an existing installation and one of the first things you'll recommend is that it be changed. Be the first to comment! All Rights Reserved.

Rely on our step-by-step guide to take you through your project. Using a Crimping Tool , trim the end of the cable you're terminating, to ensure that the ends of the conducting wires are even. Being careful not to damage the inner conducting wires, strip off approximately 1 inch of the cable's jacket, using a modular crimping tool or a UTP cable stripper. Separate the 4 twisted wire pairs from each other, and then unwind each pair, so that you end up with 8 individual wires. Flatten the wires out as much as possible, since they'll need to be very straight for proper insertion into the connector. Holding the cable with the wire ends facing away from you. Holding the RJ45 connector so that its pins are facing away from you and the plug-clip side is facing down, carefully insert the flattened, arranged wires into the connector, pushing through until the wire ends emerge from the pins.
Cables for this standard have connectors with. 6 pins. 2 wires are used for the power supply and. 4 wires for the data transfer. Besides the 6-pin connector there is.
A Computerr Port is an interface or a point of connection between the computer and its peripheral devices. Some of the common peripherals are mouse, keyboard, monitor or display unit, printer, speaker, flash drive etc. The main function of a computer port is to act as a point of attachment, where the cable from the peripheral can be plugged in and allows data to flow from and to the device. A computer port is also called as a Communication Port as it is responsible for communication between the computer and its peripheral device. Generally, the female end of the connector is referred to as a port and it usually sits on the motherboard.
