Electrical supply to a car is really important because it provides power to the starting motor and the on-board computer. Without car alternators, starter motors as well as batteries the car would have to be manually jump-started, and we would be back in the stone age as far as conveniences. The first cars had a magneto that created spark to the plugs once the engine was going. Eventually that evolved to a generator that sent electrical charge to a battery, and this system is now known as the self-charging electrical system.

Typical drivers find it intimidating when shop mechanics explain the sophisticated system during repairs. Nevertheless, the self-charging electrical system stays alike in concept, and many of the more worthy improvements are in the area of overall performance. Now, car alternators hold charge in car batteries, as well as provide electricity for conveniences and the computers. Nevertheless, reliability remains an issue with the electrical components and replacing a battery or alternator are things one can anticipate over the course of owning a vehicle.

As long as a car has an electrical source to provide spark, the engine will continue to run. This is achieved by a 12-volt car battery, however, without an alternator to maintain charge, the drain on the battery will be substantial and the system will run out of juice in a short time. Conversely, an alternator provides ample electrical to run the systems, but the engine cannot start without power from a battery. For this reason, every car owner should keep an eye on the car battery and keep it in tip top condition.

When car batteries lose their charge, some of the symptoms include slow engine cranking, slower turn signals, dim headlights and even overheating. It is easy to check a battery, this should be the first thing one should do at the first signs of a diminished electrical supply. Car alternators are also important to the system and shouldn’t be disregarded. A extensive check will determine whether the battery has simply outgrown its life span, or the alternator no longer has sufficient output to maintain a proper charge in the battery.

Today it is imperative for any business to purchase IT equipment simply to market their goods and services on the Internet. This investment is attributable not solely to the costs associated by buying the equipment, but also because these units need frequent updates, maintenance, and repairs, which often needs to be carried out by an IT professional. Then there’s the loss in profit caused by that down-time and hassle. Second-hand hardware can cut costs significantly and appeals especially to new businesses and professionals working by themselves. Therefore, purchasing used servers and used external hard drives is very attractive. They can purchase these items at a small fraction of the price and they usually run every bit as well as new hardware.

An additional advantage to choosing second-hand computer hardware is availability. However getting your hands on second hand equipment that will fulfill your requirements can look to be a herculean task, specially when you know you need a refurbished Nortel for example. If you’re using providers that actually feature used servers and second hand information storage, they will do most of the work on your behalf. Normally you can find equipment with specific features, a particular manufacturer, and some IT asset disposal services have even more choices available.

Many of the problems with new technologies are not evident until the hardware has already been introduced. As a result people who get these items just after they come out usually have to upgrade or patch the systems. Expectably, some early adopters have found it necessary to bite the bullet and replace their new system completely as a bad idea.

Naturally established equipment has been tried and tested thoroughly. You will not need to spend your valuable time resolving the issues associated with the most recently launched networking equipment. Quality need not concern you either as every item is refurbished prior to being delivered.

The key to sourcing the right second-hand hardware is choosing the right IT asset disposal services. Do some research and find a company with a good track record. This ensures the units you buy are fit for their purpose. And just in case, do ensure your items are supported by a warranty. The evidence shows that the advantages of investing in second-hand hardware are more than simply monetary. So why not save yourself time and money by straightaway buying reconditioned IT equipment and even leveraging some great IT financing options that are certain to be available?

Located in British Columbia, Canada, Icron® anticipated and improved upon the utilization of USBs (Universal Serial Bus’s) for the modern day. USB range was once limited to just around sixteen feet, a restriction that Icron has surpassed to around 1.24 miles. Together with other big software system and computer hardware giants, Icron is a member of the USB Implementers Forum. Of all the products judged by that group, only Icron’s ExtremeUSB extension technology fulfilled the requirements necessary for them to endorse their approval. Because of the name value of many of the Implementers Forum’s members, such a favorable reception is synonymous with brilliance.

For over ten years, Icron has been furnishing many areas of the computer market. Icron’s industry partners (including Accurate Technologies and Netbotz) are all utilizing Icron’s ExtremeUSB extension technology, demonstrating the true utility of the product.

Icron believes that the industrial applications of USB will expand if the enabling technology can be made more available. Icron has therefore done everything it can to make its products as obtainable as possible. Take a look at the ExtremeUSB technology and see whether any of its configurations (developer kits or OEM embedded hardware) appeal to you and your business. The Ranger and Rover products can be delivered either under their original name or re-branded. There are different power preferences that allow USB Extension over any media. In recent years, Icron has built upon the capacities of ExtremeUSB — the WiRanger Cable Free USB 2.0 hub.

The majority of devices — a far cry from the WiRanger — do not provide a combined package with cable free capacity and an in-built industrial radio (802.11g). The WiRanger has a maximum reach of over thirty m, a lightening fast connection and gets around the hassle of wires. This makes installation and general use alot easier. Bear in mind that the WiRanger is only the most recent addition in Icron’s USB 1.1/ 2.0 arsenal. The name Icron is analogous with excellence — the technology of USB is now sufficiently advanced for them to function in hitherto rough locations. Most importantly, Icron will continue to develop solutions to problems that might restrict the deployment of USB technology.

To Wire or Not to Wire

Wireless networks are en vogue, but your installation won’t be successful unless you chose the right type of network and set it up properly. Wired networks require that each computer be connected via a wire to a central location, called a switch or hub. This often involves installing cables through walls and ceilings and can present a challenge for anyone.

If the computers in your home or office are all within 500 feet of each other, a wireless network might be for you. A wireless network has no cables. It can connect computers on different floors of a building or even across the street. Aside from the obvious benefit of not having wires, wireless networks are more convenient since the setup, configuration, and reconfiguration can often be done within minutes, without extensive planning.

Wireless networks, however, are not as fast as wired networks. If you play computer games or want to view streaming video or other high-speed multimedia, a wireless network might not have enough capacity. But, if you just want to check e-mail and view web pages, a wireless network is a good choice. To install a wireless network, you need a Wireless Access Point and a wireless network card for each computer. You will need to buy a wireless network card for each desktop computer, although most newer laptops come equipped with one.

Security is not a large concern in a wired network, since someone would have to physically connect to a wired network to break in. In wireless networks, a car parked outside with a laptop could easily connect to your network if you don’t have proper security in place. To prevent this from happening, encrypt your wireless network connections, or set a password to access the network, or do both.

If you decide to use a wired network, consider whether you will install it yourself or hire a professional. If you have a small number of computers that are all situated very close to one another, you may be able to buy pre-assembled network cables and connect them yourself. If you need to wire multiple floors and lay wire through ceilings and walls, you need a professional installation. If you go this route, it is best to begin with a floor plan of your office or home, determine what your current needs are, and consider how the network design can be adapted to future needs. A professional installer should be familiar with EIA/TIA standards, local wiring and electrical codes, and making custom cables. Network cabling professionals are often judged by the neatness of their work, because sloppy cabling is more apt to deteriorate over time, harder to manage, and poses more of a fire risk.

Having a wireless network or a wired network is not mutually exclusive. Many small offices have a wired network in addition to one or more wireless networks, depending on their needs. Wireless networks are continuing to get faster, more secure, and less expensive. Wired networks will continue to coexist with wireless networks, often in the same homes and offices.

The world of computers is constantly changing. It is one of the only industries that is different from month to month. If you’re in the market for a new PC, there are continually new options available. To get the best bang for your buck in computer technology, you may want to consider building your own PC.

Those with a little know how in the computer industry can save themselves tons of money by building their own computers. Companies such as Tiger Direct and mwave.com offer components that can create a top of the line system for a fraction of the cost. These stores offer all of the necessary components that reside in the “case” or main unit of the computer.

These include the motherboard, processor, cooling fans, hard drive, memory, keyboard, mouse, video and sound cards. There are motherboards available with integrated video and sound but not all do.

When you are buying a motherboard, make sure to check whether you will need to buy a separate video and sound card. Also make sure that the motherboard you are buying has extra slots so you can expand your system.

Another key to remember when building your own computer is to make sure all of your components will work together. Manufacturers make specific models to work together, so you may want to buy your parts from just one brand.

If you are going to use your computer to surf the Internet and play computer games you are going to need extra pieces. At minimum you will need an Ethernet card, CD/DVD drives and a graphics card. You can also benefit from gaming ports for joysticks or other game controllers.

The hardest part about building your own PC is installing the motherboard and the Operating System. This is the first step toward creating the unit. You must physically put the components into the case using screws. Begin with the motherboard and then connect your processor. Add the memory into the memory slots and install any necessary drives.

Once you’ve installed the drives, you can put in the install CDs for your operating system. Most PCs will guide you through the set up process to install the operating system. After making sure the operating system is up and running, put in your other devices one at a time.

Although it may be quicker to install all of your additional hardware at once, you want to test each piece as you go to make sure that piece is in good working order.

Even though building your own PC can give you a better computer for less money, the process is not for everyone. As a compromise, computer companies like Dell and Gateway allow their customers to custom build PCs on their website.

A customer can choose from different options regarding speed, memory and special portals. The additional benefit of buying from a company is that the PC is normally under a guarantee. You can also take advantage of technical support. This may be the best option for someone who has extra money to spend to get the custom components that they want.

One of the latest services that is growing steadily is “email to phone”, whereby you can receive email messages by voice over the phone, or send voice messages as emails from any phone – cell phone, satellite phone or a regular land line.

When I first heard of this, I wondered, “Why would I want to listen to my email instead of reading it?” But I soon learned that there are a great many people who can stay in much better touch receiving email messages by phone. Here is a list of the top ten reasons I have complied to use an email to phone service:

Email to phone for busy people on the run

1. You can pick up a message any time, any where, even if you had not planned to. Have you ever had that eerie feeling there was an urgent email waiting for you? Now you can relieve your curiosity, deal with the email and feel 100% assured that landing the sand trap was not a result of email anxiety.

2. Receiving emails by phone is ideal for a busy person on the run. Between the meetings and the restaurant and the cab, a busy person does not always have the time to sit down in front of a computer. But he always has time for his cell phone (You might have noticed this in restaurants, theatre shows, etc.)

3. International travelers have a great use for email to phone services, as they cannot always foretell the availability of a computer or an Internet connection, nor how much time they might have between flights, meetings, etc. This way, they can keep monitoring all their urgent messages wherever they end up, and delayed flights will no longer mean delayed business.

Email to phone for constant access

4. There are some places where you just can’t plug into your computer (or would not want to). On a boat, for instance. With email to phone messaging, you can receive email while you relax on a boat, far from an Internet connection. And yes, it IS relaxing to know you don’t have to fret about a missed email that could bring down the company or cost you your job.

5. On a hunting or fishing trip, you might often find yourself with no Internet connection. And you certainly won’t have a computer with you (I hope!). But you might have cell phone access. And if one of your hunting buddies does drag along his PC from home, you can tell him to get an email to phone service instead.

6. Check in at the cottage, without lugging a computer around. Need I say more. It is indeed relaxing to know you don’t have to fret about a missed email that cost you your job. It is NOT relaxing to have to open your eyes to look at a computer monitor.

7. There are also many countries where Internet access is not reliable, even in parts of well-traveled countries. Who needs Internet for emails, when you can receive them by phone?

8. Indeed, even in your own country, there might be areas you frequent that are outside of the digital coverage area, where SMS and text messaging are unavailable, such as driving through deserts or mountains. Even with analog coverage or a regular phone line, you can keep monitoring your email.

Special monitoring email by phone

9. Some people need instant alerts, and have to be in touch even while in the lunch room or traveling between meetings. IT support people, who subscribe to a website monitoring service are a perfect example. If a company’s website goes down, the CEO won’t be pleased if 45 minutes later the IT manager says, “Sorry, I was out to lunch.”

10. Some people have the misfortune of having to communicate with high-tech show-offs like me who use email to communicate. For these unfortunate people who might otherwise be forced to adapt to 21st century technology, email to phone messaging rides to the rescue. “Hah! Now I can listen to email messages on my cell phone. And they thought they could force me to adopt modern technology. Hah! I sure fooled them!”

There you have it – my top ten reasons to use email to phone services. Amazing how new ideas can turn even a stone-aged telephone into a technological leap forward. Imagine what they’ll do with boulders next.

In sharp contrast to warranty options on desktop PCs, consider advising your clients to purchase the maximum extended warranty coverage they can with a new notebook PC purchase. Even beyond a potential hard drive failure on a notebook, consider the cost of replacing the LCD screen.

Potential Costs for Replacements

Unlike a conventional PC monitor, notebook PC LCD screens are highly specialized for particular notebooks. If a client needed to replace a standard 17″ or 19″ monitor that’s out of warranty, your client would generally have no problem finding equivalent products at local retail outlets for relatively modest prices of about $200 to $300.

For a notebook PC LCD screen, your clients would almost never find the parts in stock locally. And the LCD screen, related assembly, and cable purchased separately easily could run $1,000 or more.

Ask Questions

As a consultant, you should ask questions of your client and the warranty provider before making any recommendation. For example, ask:

Are the notebook PCs that your major clients own typically used more in the office or in the field?

Can you get a copy of the notebook PC system warranty statement?

How does the notebook PC warranty statement differ from the desktop PC warranty statement?

Does the warranty specifically include or exclude certain hardware components?

Are there any warranty restrictions regarding replacement of the hard drive or LCD panel?

What is the duration of the included warranty coverage?

Is your PC vendor the one selling and honoring the extended warranty policy? If the extended warranty is subordinated to a third party and the third party goes out of business, will your PC vendor still honor the warranty?

The Bottom Line about Notebook PCs

So because of the risks of hard drive and LCD screen failures on a notebook PC, buying an extended service plan becomes a no-brainer for most of your clients. This is also the primary reason extended warranties on notebook PCs cost a lot more than comparable extended warranties on desktop PCs.

Having a notebook or laptop provides the freedom to be truly mobile. You can work in many places and situations. But this brings an annoyance: if you move your notebook between various different networks, you always have to change network settings.

Recently my employer has issued me a brand new notebook. When I came home at the end of the day, I had to disable DHCP, set up an IP-address and DNS configuration. Next morning I needed to reverse my configuration to work at my office. The real headache began when I went to our customer site…

SWITCHING NETWORK SETTINGS ON THE FLY.

There are three ways to switch a notebook between networks with one click. First is to use a built-in windows feature of saving and loading network settings. This way is for experienced users. Second is by using Windows XP “alternate configuration” feature. The third way is to use third-party utilities like Net Profile Switch, IPSwitch etc. Let’s discuss all three.

WINDOWS “NETSH” UTILITY.

Windows 2000 comes with the “netsh” utility that gives you the possibility to “dump” all network settings into a file which you can later use to restore your complete Network settings.

To Save the current Settings use “netsh -c interface dump >netset1.txt”
To Load the Settings again use “netsh -f netset1.txt”

Create a dump file for every Network that you use (e.g.., netset2.txt, etc.) and create a desktop shortcut for every Network.

Pros: -
Cons: hard for inexperienced users, does not deal with switching a proxy server in a web-browser, mapping network drives etc.

WINDOWS XP “ALTERNATE CONFIGURATION” FEATURE

Windows XP contains the “Internet Protocol (TCP/IP) properties” dialog box, which has a tab “Alternate Configuration” in it. You can specify “alternative” settings, which would be used when the “default” settings are not accessible.

Pros: simple
Cons: does not deal with three or more networks, no proxy switching etc.

“NET PROFILE SWITCH” UTILITY

Another way is to use the “Net Profile Switch” utility from Jitbit Software (http://www.jitbit.com/). This tool creates a profile with your configuration settings, and you can easily switch between locations by activating a profile with one click. Net Profile Switch not only switches the TCP/IP protocol settings but also switches the proxy-server settings of your Web Browser (Internet Explorer or Firefox), Windows Firewall settings and maps/unmaps network drives for each location. There a free non-commercial edition of this tool available.

Pros: multiple locations, proxy settings, drive mapping etc.
