What is cabling? Cabling is the foundation of your network, it is the medium that connects all your computers and servers together and is probably one of the most important and often overlooked items in business networks. The process begins by installing a twisted pair cable made up of twisted wires surrounded by a protective jacket to connect data lines to a computer or other network component. The cables are run through ceilings and walls, out of sight, and link a data/phone drop to a patch panel, or other termination block often installed within a rack in a server room or telecom closet. Simply put, cabling is used to link together computers so they may form a common network and communicate...

> Electrical power can be one of life's requirements within the modern day world. In Great Britain and also worldwide most of us count heavily on the know-how of electric personnel. Electrical certification can lead on to numerous positions, conditional upon an individual's study or knowledge. In the order of three percent of the UK's GNP may be related to the power sector. If it's time to bring about some occupational changes, learning to develop into a domestic electrician is undoubtedly a great approach. The two pertinent trade accreditation bodies within the UK will most certainly be EAL together with C&G (City & Guilds). And of course, young people engaging in City & Guilds exams available at...

NTP servers (Network Time Protocol) are devices that can synchronise a computer network to an authoritative UTC time source. UTC (Coordinated Universal Time) is a global time scale used throughout the world and provided by atomic clocks. NTP servers can receive UTC time either across the Internet from places such as nist.gov or windows.time. However, it must be noted that Internet based timing references can't be authenticated and may leave a network vulnerable to malicious attacks such as DDoS (Distributed Denial of Service - normally caused by malware that floods a server with traffic) that blocks access. Fortunately dedicated NTP servers can receive an authenticated timing reference through...

The RJ-11 is currently the most widely used phone jack. These connectors are utilized to terminate phone lines and are generally installed with single line Plain Old Telephone Service (POTS) jacks. Among all the registered jacks, they are the most common ones where virtually all of the telephone jacks in offices and houses in North America as well as other countries use this form of connector. Another feature of such connectors is they are often encased in plastic and designed modularly. The modular pattern implies that the components such as connector and telephone jack can be plugged with one another instead of being hard-wired. The RJ-11 connector applies the use of six position and four contacts...

Network media is what is used to connect Point A to Point B. Most people think of media as cables, but air is also media for wireless devices. I will explain several different types of media - Coaxial cable, Unshielded Twisted Pair cable, fiber optic cable, and wireless media (air). Coaxial Cable Coaxial cable, also known as "coax", utilizes one wire. There is a copper wire in the middle of the cable that is used for data transmission. Around it, there is an insulator that prevents the copper cable from touching the braided shield layer. If the copper core touched the shield layer, the signal would get scrambled or there could be an electrical short, so the insulator prevents that. The braided metal...

Ethernet cable is one of the most common and important elements in modern computing and home entertainment set ups. Typically an Ethernet cable is used to connect a device, such as a computer or a games console to the internet and to networks, allowing for online usage, downloading and streaming. Fortunately, Ethernet cables are so widespread that it is not difficult for amateurs to find a suitable item for their needs. One of the first things to remember however is that not all Ethernet cable is exactly the same, there are a variety of categories that vary in terms of quality; that quality determining the amount of data a specific cable can handle. Cat 3 cable is usually used for voice...

:: The Definition of Backbone Cabling Backbone cabling may be within one building or between buildings on a campus. All wiring between telecommunication rooms is called as backbone cabling. In many cases, backbone cabling is actually between wiring closets on the same floor of a building, but the more typical case is the floor to floor wiring in a multi-floor building. Many call it vertical cabling in contrast to horizontal cabling. :: How are backbone wiring implemented? Typically all hubs, concentrators and switches are placed in the telecom rooms which serve all workstations on that same floor. Backbone wiring then connects the hubs, on to another on different floors.o Daisy Chain wiring. In a...

Put simply Ethernet cables are used the world over to connect computers together. They can also be used to connect computers ton other devices such as scanners and printers.

There are many business owners and staff that are unaware of how much they are damaging their business - by not doing the 'little things' that add value to their product or service. Seemingly simple or even trivial things can make the difference between an unhappy customer and a raving one. But there's a warning here. Adding value, or going the extra mile doesn't usually mean you have to walk over hot coals for your customers. And it doesn't mean you have to give away profit either. In most situations it's the opposite. All you have to do is the little things - the 'little things' that make a big difference to the CUSTOMER. So don't worry about giving away a lot of product, or a lot of times to 'add...

You are finally up and running on your wireless network. You designed it and built it and it works! Well, sort of. As you begin to evaluate the wireless network's performance, you find that it is not quite as good as you had planned for or anticipated. What can you do? First, you need to determine if your expectations were grounded. If you expected to get the same throughput and speed of transferring files across your wireless network as you were used to on a wired Ethernet network that was wrong. Wireless speeds are plenty adequate for Internet access but are pitifully slow compared to the wired Gigabit throughput of your hardwire connection. Let's assume it is not an issue of expectation but there...

Electronic imaging consumes large amounts of bandwidth and data. Current connections to the home consist primarily of modems running at 33.6 Kpbs or 56 Kpbs. For those users who deal with still images and video, these speeds are not acceptable. The home needs fatter pipes in order to proliferate any kind of imaging services or if someone is trying to sell different types of imaging appliances that intend to use the Internet infrastructure. The home user has to contract with an ISP for a flat-rate monthly fee. The ISP usually provides a dial-up line that the consumer uses with s standard modem. The cost of a dial-up line is usually under $20 a month. Many new technologies have been developed with the...

A lot of people have probably heard about 4G wireless broadband technology and how it is changing the way we use our mobile phones. 4G is a wireless broadband internet standard that would seek to increase the rates of wireless data transfer. That would mean mobile phones or smartphones with the 4G technology would benefit in terms of faster download and upload speeds. So watching and downloading videos would be a cinch and there would be no more need to wait for webpages and videos to buffer on the phone's browser. 4G is not just proprietary to mobile phones, even laptop and desktop computers can benefit from 4G wireless internet technology through the use of USB sticks or dongles, which basically...

telephone companies have extensive networks all over the world, so also do power companies. There’s a key difference here — power companies have lines in many more places than phone companies can install fiber optic cables. Therefore, it is obvious that power lines can be used to bring the Internet to places where fiber optics cannot reach. Back to basics. Power lines are just one part of an entire network consisting of power grids. Apart from the lines, the power grids make use of various other items of equipment and infrastructure such as substations, generators, transformers etc. that transmit the electricity from the power plant right to your wall socket. Power from the power plant...

If you are anything like me, I look at the back of my PC and am intimidated to even guess what the purpose for all those cables are. I rarely dare to go behind my computer and try to figure out how each one does what it needs to do. There are blue ones and black ones, short ones and long ones, thin ones and wide ones. I have my speaker cables, monitor, keyboard and mouse cables. I understand those but what about all the other ones? How are they able to work so seamlessly when I turn on the computer and yet look so chaotic behind it? The computer cabling that is the most confusing for me is the ones to make the Ethernet work. How can one (fairly small) cable connect a whole home network to use the...

p>We all have job titles. And job descriptions. These are often so clichéd that when others ask us what we do, we have grown accustomed to responding with these generic automated answers that lack real impact. Listeners find out little about what we really do or what sets us apart from competing businesses. There are ways to distinguish yourself when making introductions in those crucial networking situations. Whether you're a cashier in a retail store or a pet groomer at a local animal salon, you can creatively affect someone's first impression of you by considering the words that you use. Most people take a basic approach when introducing themselves. They offer the one or two word...

Multimeter. The multimeter needed to do these tests is an inexpensive ($10) handheld analog one having a needle-deflection readout, and run by an AA-battery. Although multimeters can make several electronic measurements, the only two needed here will be the 150-VAC (volts alternating current) and the resistance (ohms) ones. Otherwise, a multimeter is kept in the off setting to save the battery. For mini-lights, a multimeter can be used to test the following issues. 1. The circuitry voltage (120-VAC) while plugged into an outlet. These two wires work independently from the bulb wire attached to them in a three-wire string. 2. The continuity of the two 3-amp buss fuses in the male plug if the...

Tunneling is used to alter the placement of electrons in the floating gate. An electrical charge, usually 10 to 13 volts, is applied to the floating gate. The charge comes from the column, or bitline, enters the floating gate and drains to a ground. This charge causes the floating-gate transistor to act like an electron gun. The excited electrons are pushed through and trapped on other side of the thin oxide layer, giving it a negative charge. These negatively charged electrons act as a barrier between the control gate and the floating gate. A special device called a cell sensor monitors the level of the charge passing through the floating gate. If the flow through the gate is greater than 50...
