A lot of the problems with advances in technology don’t become evident until the associated hardware has already been launched. This means that companies who invest in these items just after they pushed into the market often have to upgrade or patch the new computer hardware. As a matter of fact it is not unheard of for companies to take the loss and replace the new system completely. Of course older hardware has the advantage of having been tested by a huge number of businesses. You will not have to spend time resolving the bugs frequently found in brand new hardware. In addition, because they’re throroughly tested out prior to sale, you do not need to be worried about the quality.

Using the right suppliers is the key to getting the best deal. Take your time and find a supplier that really has the industry experience to do the job efficiently. This ensures the units you purchase are fit for their purpose. A guarantee also helps, in case something goes wrong.

The evidence shows that the advantages of buying second-hand IT equipment are more than just monetary. Therefore why not save your company time and effort in the long run by buying second hand and, going beyond, making the most of some great IT financing options while the going is good?

BT has announced that it is planning to spend over £1.5 billion in upgrading its fibre optic network, which will offer super fast broadband to its users. In a welcome move, around 10 million homes and offices in UK will be getting ready for fibre-optic installations beginning late 2010. The works are scheduled to be completed by the summer of 2011.

BT is planning to provide two types of upgrades depending on whether the work will deal with fibre-to-the-cabinet or fibre-to-the-premises lines. The fibre-to-the-home technology promises homes a 100 MB download while business supplied with the fibre-to-the-cabinet upgrade can look forward download speeds of up to 40 MB (see business broadband info). The Register, a news website, is confirming that 75 percent of the upgrades will be in the latter sector that is the businesses while 25 percent will be the home consumers. The website has provided a list of 300 locations that may be in the offing for the upgrade. Meanwhile BT has not confirmed which exchanges will receive which technology.

Most of the upgrades will be in built-up and urban areas, with a maximum number of areas slotted in either London or the South East.

Ofcom, the telecommunications watchdog is quick to point out that BT should also consider allowing rivals like TalkTalk and SkyPlayer the use of the fibre-optic upgrades for providing services.

Virgin Media had launched a service called XXL some time back which provides the internet user with a downloading speed of 50 MB. The service entails a 12-month contract. It also provides unlimited downloads throughout the month without any caps. BT has recently announced a new product, called Infinity, which it plans to launch in the market soon and make it available in at least four million homes. The number of homes it will become available in will increase to 10 million within six months of the launch.

When BT compared its new product, Infinity, to XXL’s service and applauded Infinity, Virgin Broadband hit back stating that Infinity is a fibre optic product which provides internet speeds of only 40MB. BT’s service also entails an 18-month contract compared to Virgin Media’s shorter 12-month deal.

According to BT, its users will save up to £7.47 by using Infinity. However, it also provides a 20GB cap on data download per month.

As a counter to BT’s claim, Virgin Media stated via a spokesperson that there is no reason why anyone would want to wait for Infinity to be launched when they could already take advantage of XXL which is a much better service.

Virgin Media has not stopped only at this. It has also stated that it is building a new fast broadband service which will provide the user with a download speed of 200 MB. However, this product is still in the development stage and the date of its launch is also not yet determined. Market conditions have not been very good and Virgin Media wants to keep that in mind before launching its new service.

There’s another conversion that might rear its ugly head on your Cisco exam, though, and that involves hexadecimal numbering.

Newcomers to hexadecimal numbering are often confused as to how a letter of the alphabet can possibly represent a number. Worse, they may be intimidated – after all, there must be some incredibly complicated formula involved with representing the decimal 11 with the letter “b”, right?

Wrong.

The numbering system we use every day, decimal, concerns itself with units of ten. Although we rarely stop to think of it this way, if you read a decimal number from right to left, the number indicates how many units of one, ten, and one hundred we have. That is, the number “15″ is five units of one and one unit of ten. The number “289″ is nine units of one, eight units of ten, and two units of one hundred. Simple enough!

Hex numbers are read much the same way, except the units here are units of 16. The number “15″ in hex is read as having five units of one and one unit of sixteen. The number “289″ in hex is nine units of one, eight units of sixteen, and two units of 256 (16 x 16).

Since hex uses units of sixteen, how can we possibly represent a value of 10, 11, 12, 13, 14, or 15? We do so with letters. The decimal “10″ is represented in hex with the letter “a”; the decimal 11 with “b”; the decimal “12″ with “c”, “13″ with “d”, “14″ with “e”, and finally, “15″ with “f”. (CCNA candidates will remember that a MAC address of “ffff.ffff.ffff” is a Layer 2 broadcast.)

Practice Your Conversions For Exam Success

Now that you know where the letters fall into place in the hexadecimal numbering world, you’ll have little trouble converting hex to decimal and decimal to hex – if you practice.

How would you convert the decimal 27 to hex? You can see that there is one unit of 16 in this decimal; that leaves 11 units of one. This is represented in hex with “1b” – one unit of sixteen, 11 units of one.

Converting the decimal 322 to hex is no problem. There is one unit of 256; that leaves 66. There are four units of 16 in 66; that leaves 2, or two units of one. The hex equivalent of the decimal 322 is the hex figure 142 – one unit of 256, four units of 32, and 2 units of 2.

Hex-to-decimal conversions are even simpler. Given the hex number 144, what is the decimal equivalent? We have one unit of 256, four units of 16, and four units of 4. This gives us the decimal figure 324.

What about the hex figure c2? We now know that the letter “c” represents the decimal number “12″. This means we have 12 units of 16, and two units of 2. This gives us the decimal figure 194.

Tips For Exam Day

Practice your binary and hexadecimal conversions over and over again before you take your CCNA exams. Binary math questions come in many different forms; make sure you have practiced all of them before exam day. The number one reason CCNA candidates fail their exam is that they’re not prepared for the different types of binary math questions they’re going to be asked, and that they aren’t ready for hexadecimal questions at all.

You don’t have time to learn how to do in on exam day. You’ve got to be ready before you go into the exam room, and the only way to be ready is a lot of practice.

Finally, make sure you read the question carefully. You’ve got hex, decimal, and binary numbers to concern yourself with on your CCNA exams. Make sure you give Cisco the answer in the format they’re looking for.

The type of Internet hosting service you chose for your business will determine if you fail or are a success as an online business. Planning to venture into the world of Web, the first step for a company will be to have a reliable service for Internet hosting which understands all its needs. Whether it is posting promotional blogs, launching a website or other activity, Internet hosting service is certain. Actually, selection of Internet hosting service counts heavily in the success of any online business. Or one may say that a better website host is the underlying difference between a a successful and failed online business.

Companies working to make their presence on the Internet will find a large number of hosting services. These services are primarily limited to the web such as web hosting service, reseller hosting service, shared web hosting service, dedicated web hosting service, virtual private server, managed hosting service, home servers, collocation web hosting service, etc.

Some companies believe that simply setting up a web page bearing their custom log, a brief account of services and a contact number will be sufficient. But the perception holds true in some cases, not all.

For instance, if a business has a wide range of products to sell, then merely a home page for online business will not do. In such a case, the business should explain all its services and products through customized web pages that give it prominence on the Internet. For accomplishing this task, application hosting service will be the best option since it fulfills all the business requirements.

Normally, people show concerns for other services such as e-mail hosting services, mail list management and DNS hosting services that are associated with web-based applications. Thus, for best results, application hosting services need deep and comprehensive technical expertise and support.

Thus, businesses should hire a professional to run hosting services who not only understands their requirements but also provide appropriate solutions. A business definitely has several other things to consider besides this and all that is dependent on the kind of website and equally on what sort (and magnitude) of presence the business wish to mark online. Selecting a decent web hosting service guarantees that the concerned business is eventually able to get value for money.

However, whatever Internet hosting service a company opts for, the main thing that it should keep in mind is the security of that service. It is a must for every online company to have an appropriate firewall, server spam filter and other security software in place. This will help the company a big deal to avoid various kinds of malicious threats. Rather, the company should be extremely attentive towards this in case financial transactions are taking place via its website. Ensuring the complete safety of the website will also help the company earn a good name among customers as they will feel their transactions safe on their website.

Blackberry and Palm Pre are not as successful as iPhones, as Blackberry accounted for around 12% of the data traffic via mobile broadband while Palm Pre accounted for merely 5% of the same in October, which is 5% lesser than September. Thus, it seems that Apple’s iPhone has conquered the market, though others have not been that successful.

This was found by a mobile advertising company AdMob that did a study on the data traffic via 3G mobiles. The company checked more than fifteen thousand websites that advertise smartphones and looked at the applications for buying these phones in order to find out the popularity of different phones.

In addition to the above conclusions, the study also showed that smartphones using Google’s Android operating system have become very well known, as these phones have contributed for close to three quarter of the data traffic in October 2010, at least in the USA.

This establishes that the real guilt of clogging the network is on iPhones. Most of the other smartphones are not used so much that they can lead to congestion in the network. This congestion has been troubling mobile internet service providers who have been trying to manage the load so that subscribers can get good services.
