...Step 1: Mounting the power supply to the computer case A fairly simple step to get your started. Before messing with the motherboard, RAM, and CPU, I mounted the power supply to the computer case. Simply slide the power supply into the computer from the INSIDE. I’ve heard horror stories of people trying to jam the power supply through the back. Once you get the power supply into the case, the mounting holes should line up like so… Simply tighten down the screws that were provided and TADA, you have taken the first step in building your own computer! Congratulations! Step 2: The Motherboard Adding the processor (CPU) The CPU is considered the “brains” of the computer. This little piece of metal and silicon is involved in 100% of your daily computing activities whether it’s something as simple as clicking your mouse or something as complex as editing the video you just took of a recent vacation. Because of its importance, you should handle this piece with EXTREME care. Once you have located your CPU socket, the area that will house your CPU, you are ready to mount the CPU to the motherboard. Unpackage your CPU and any other parts that came with it (likely a heat sink and maybe some thermal compound). Typically, new CPUs will come with a heat sink and thermal compound applied to it already but if not, you WILL need to apply thermal compound to it. Processors can easily reach 100 degrees Celsius otherwise known as the boiling point for liquids…not a good thing! ...

...Assignment 3.3 When terminating a twisted pair cable with an RJ45 connectors there are essentially 3 tools that you need to complete this task. There are many methods and connectors on the market to terminate an RJ45 cable but the steps are all very similar. The first tool that you will need is a “wire cutter” tool. The cutter tool is used to cut through the entire cable at both ends once final length is determined. The cutting tool is similar to a pair of typical wire cutters or scissors in method of how it works. The next tool is a “cable wire stripper”. It has an adjustable blade that is used to score the outer casing on the cable and enable you to strip it away. Once the cable has been cut with the wire cutters to length, the wire strippers are used to cut back about an inch from the end to remove the outer casing of the cable. This will free up the twisted pair wires and they can now be threaded in to the RJ45 connector. The last tool that is used is the “crimping tool”. After the twisted pairs are exposed and threaded into the RJ45 connector, the entire connector is inserted into the crimping tool and is compressed closed to allow all the connector blades to pierce through the outer case of the individual twisted pair wires.

...Unit 4 Assignment 1 Copper vs. Fiber Pape The two most common and widely used cabling types today for the means of communication all over the world are copper and fiber. They both do the same thing, transmit information from point A to point B but both have their strengths and weaknesses and therefore, a person installing cabling may be reluctant to choose one over the other. Copper cabling is less expensive to install. Copper wiring is flexible when installing so incase a technician has to bend it around a wall or at a certain angle to reach it to an end point, the cable can handle it. Also equipment to support copper wiring is relatively inexpensive to run. The weaknesses to copper wiring would be that it is susceptible to electromagnetic inference (EMI) from outside forces and also has a higher rate of corrosion over time by oxidation. Fiber optic cabling is a more expensive option for communications. Fiber optic cabling is immune to EMI and other noise interferences and therefore the chance of signal loss is greatly reduced. One drawback on this type of cabling is that just like its copper; fiber optic cabling is very durable and tough making it harder to work with when it comes to installing it. A technician will have to be very well trained in handling it to get the most out of it for the customer. But fiber optic cabling has a much higher bandwidth over copper so it can handle much more traffic as well as at higher speeds than copper wiring. In the real world, one...

...Connector Installations * Strip the cable of its protective outside jacket about 3-6 inches from the end. This can be done with the cabling scissors by applying pressure from the scissors to the cable and rotating the scissors around the cable. After you have punctured the cables jacket, you should be able pull the jacket off easily leaving exposed wires. * Expose the wire a little further. Stripping the cable can cut and damage the wires at the area that we cut the cable so we want to expose about 6 more inches of fresh wires. Most twisted pair cables have a small string inside the cable to assist with this. * If your cable has the small string. Cut the string after you have enough exposed cable. * Untwist the wires completely to the jacket. Place the wires into the appropriate color slot on the jack. Make sure to place the wires as tightly as possible in the slots in regards to the jacket. There should be as little exposed and untwisted wire as possible to keep the signal strength as high as possible. Make sure to place the White/Blue in the White/Blue spot and not the solid Blue spot. The White/Color wire is not the same as the solid color. * Terminate each wire. After all the wires are in the correct spot and double checked to make sure as little amount of exposed wires will be left as possible, use the punch down tool with the 110 blade and terminate each wire individually. The 110 blade will fully cover the wire connector on the jack. Push down until...

...Cabling Pin-Out On the back of each keystone jack is a two-sided connector that is labeled with similar colors. In the keystone jack we're using, the label has sets of colors labeled A and B. This refers to the two main wiring standards used in Ethernet, 568A and 568B. You can use either standard as long as you are consistent with that standard throughout your installation. Using the 568B standard, the left side of our keystone jack is labeled (from top to bottom) blue, white-blue, orange, whiteorange, and the right side is labeled green, white-green, brown, white-brown. Working from the top, place the specified color in the corresponding slots on the top row of slots on connector. Try not to untwist the wire, since the Ethernet standard requires the wires stay twisted down to the last 1/2 inch.

...http://ammtiac.alionscience.com/quarterly Larry X Schneider Pulsed Power Sciences Center Sandia National Laboratories Albuquerque, NM The article entitled “Wired for Success: Ensuring Aircraft Wiring Integrity Requires a Proactive Systems Approach”, which was published in Vol. 8, No. 3 of the AMPTIAC Quarterly (a predecessor to the AMMTIAC Quarterly), established the importance of maintaining wiring integrity, especially in aging aircraft. The article also emphasized the need for nondestructive approaches for evaluating the integrity of wiring systems and components. The current article answers the mail in terms of providing a nondestructive inspection (NDI) method to proactively ensure wiring integrity. – Editor INTRODUCTION Detecting and locating insulation defects in wiring systems is a nontrivial challenge. Ideally, the diagnostic should be nondestructive, capable of detecting a variety of insulation defects, such as cracking, chaffing, and abrasion, and be able to locate the defect accurately to reduce potential inspection and maintenance costs. The diagnostic should also have a low rate of false detection. Complicating this quest is the nature of complex wiring systems. For example, aircraft wiring systems are comprised of harnesses containing periodically bound single wire pairs* which create highly non-uniform impedance characteristics due to the varying distance between wire pairs. Insulation defects may also be physically small, resulting in...

...The i-RAM is a pseudo-solid-state drive produced by Gigabyte and released in June 2005,.[1] It has four DDR RAM DIMM slots. Connection via a SATA port enables a PC sees the i-RAM as a hard drive(which can be made bootable). The i-RAM is bottlenecked by the SATA interface, which limits bandwidth to a maximum sustained throughput of 150 MB/s. This speed limitation is offset by near instant access, with a latency of 0.1 ms. i-RAM Version 1.3 Backup Battery DRAM is volatile, so power loss will cause data loss. The i-RAM is installed in a PCI slot, which powers it while the PC is plugged in (using standby power if the PC is off). It has a backup battery (10 to 16 hours depending on the configuration), which operates when the PC is not connected to AC mains power. The i-RAM supports Unbuffered/Non-ECC DDR 200/266/333/400 MHz RAM modules of different capacities (up to 1 GiB), speeds, and brands for a maximum capacity of 4 GiB. Because of this, cost per GB is high, but the device offers a non-mechanical storage method with higher performance than a traditional hard drive. The I-Ram has the advantages of fast transfer rate and access time, no moving parts, a lower cost than traditionalsolid-state drives, unlimited write cycles compared to flash memory and it doesn't slow down over time. However, it has the disadvantages of high cost compared to traditional hard drives, low capacity (4 GiB maximum), the transfer rate restricted by SATA 150 bus (1.5 Gbit/s), it is not physically compatible...
