It is inevitable for professionals these days need to do some field work or travel. While it is necessary for engineers and architects to be on the field most of the time, this can also hamper some of their work. That is why it is necessary for them to have a mobile workstation which can help them continue working and using their CAD applications even while they are away from the office. The mobile workstation is an essential replacement for the normal Cad system or workstation. This enables them to carry on with their work even while they are on field work. However, the requirements for such a tool are often overlooked by most businesses. There are less informed professionals who insist on buying the regular laptop without the specifications required to run the CAD software. The repercussions for such buying decisions are often catastrophic and may lead to bigger loss for the business. If you are wondering why it would be catastrophic for any business to make a default decision to buy the usual laptop with ordinary specifications, you must have an idea of the difference in operation between a laptop and a specialized mobile workstation. A laptop is often used in business by sales and marketing professionals who are always out of the office and meeting clients. Sales people often make use of simple applications for typing documents, making presentations or using excel worksheets. They also use these portable computers to browse the internet and check their emails. Such functions do not require a high-powered processor in order to get the work done. However, if you are to run CAD applications on this laptop, you might not be able to be as efficient as you want to be. One of the major reasons why an ordinary laptop will not be able to perform the functions of a specially-designed mobile workstation is that the processor of an ordinary laptop is not as hard-core as that of a CAD workstation. This is why most laptops break down on occasion when they try to run some CAD programs. The processor required in order to efficiently run CAD programs should be dual or multiple core processors. It is also essential to have certified graphic cards in order to get the best out of the CAD application software. A faster and bigger hard drive is also needed to contain all the information in...

Cat5e, Cat6 cables are good choice for the newly network cabling systems. If you are running the two standard cable technologies at home or office, it is very necessary that you terminate the Cat5e, Cat6 cables with the RJ45 keystone jacks for them. In case that some of you are still not so familiar with how to terminate the Cat6 or Cat5e network Ethernet cable with a modular jack, I would like to take readers through all the termination and installation steps and general information that should be used to complete this tedious but important task. RJ45 modular jack RJ45 modular jack is one kind of the keystone jacks that used for networking. The RJ45 modular jack provides an excellent method of bringing network connections into any room and it fit for all the standard keystone jack network faceplate. T568A and T568B are the two wiring standards for an 8-position modular connector, permitted under the TIA/EIA-568-A wiring standards document. The only difference between T568A and T568B is that the pairs two and three (orange and green wire pairs) are interchanged. T568B is very common in the USA. In the RJ45 keystone jacks, both T568A and T568B wiring schemes are labeled. Take the Cat5e Network Ethernet Cable termination steps for example, Cat6 cable follows the same way. Cat5e Cable Termination Steps: 1. Cut the Cat5e cable with a cable stripper. Trim the cable about 3/4 to 1 inch into the jacket, making sure that you hasn’t damaged the conductors inside. Romove the cut jacket by simply pulling it off. 2. Separate the twisted wire pairs from each other; Untangle the scrap piece of jacket downwards on each pair of wires and then fan out all four twisted pairs. 3. Remove the jack’s protective cap. You will see there are wire configurations printed near the termination slots. If you are given a choice between “A” and “B” configurations, choose whichever you are currently using. 4. Match up the colored wires with the corresponding color codes on the keystone jack by placing all 8 wires into the center of the jack 8 wires into the center of the jack. 5. Use a punch down tool to punch the wires down into the blades of the keystone jack. To punch down each wire, press down on the punch down tool until you here a loud click and simultaneous, metallic-sounding “ping”. In this step, it...
