Data centers – where would we be without them?

1 Reply Christopher Roberts

It is hardly a controversial opinion to suggest that data centers are an indispensable part of modern life – it really is impossible to envisage a world without the vast capacity and power that data centers grant the business and information technology sectors – where would we all be without Google, eBay and Facebook? But what exactly are the advantages of a data center that their absence would remove? Let’s take a look…

Firstly, the cost to enterprises of running an in-house own data center is increasingly prohibitive, given the growing size requirements of such facilities. As more and more information is transmitted online and more transactions take place online – just as computing power continues to grow – then a data center needs exponentially more power and more hard disk space. Server racks just keep on getting longer and even keeping them cool enough becomes uneconomically costly for most small, medium or even large-sized enterprises.

Server RoomSecurity is the second big issue – in a world where cyber-crime and espionage is constantly growing, there needs to be a very robust response to security. Most enterprises just don’t have the time and resources to police their IT operations to the level required, and a good data center can give them the reassurances they need. Technicians can be on hand throughout the 24-hour cycle, not just to ensure that the server racks keep on functioning perfectly and that any problems are swiftly dealt with, but also to ensure that information is kept safe and secure and that hacking or phishing attempts are roundly thwarted.

So, where would we be without data centers? The answer is that we would have a vastly more limited cyber-world, with businesses forced to keep their computer operations artificially scaled back due to cost considerations, with the knock-on effect of a hobbled e-commerce sector. Social networks would be slow, unsafe and prone to disastrous infiltration, while search engines would also be grindingly slow and frustrating to use – welcome back to the late 1990s.

It’s safe to say that data centers are not only here to stay, but will keep getting bigger and better so long as the computer world leads the way.

How to share a mobile broadband connection

2 Replies Joe Linford

With the increase in mobile broadband technology, many people are increasingly turning to mobile dongles (like the ones here) at home instead of traditional connections, which cuts out the need for a fixed-line. However, with mobile broadband there are certain problems that can arise, the most obvious being that of sharing your internet connection with another device.

However, that needn’t be something that you become overly concerned with, as these days there are a variety of ways to share your mobile connection.

Most of the top providers are now offering technology to allow you to do this, such as 3 Mobile’s MiFi. With this you simply purchase the 3 MiFi and you’re away. It works pretty much the same way as a dongle, with one difference.

With a dongle you have to plug it into the machine, with MiFi you don’t, and can therefore connect to multiple devices at the same time. The devices themselves are small and easily portable; however, as is often the case with mobile broadband, internet speeds can be a little slower than hardwiring or even traditional Wi-Fi.

This doesn’t just mean you can connect to another Wi-Fi enabled laptops, games consoles or mobile devices, but also other Wi-Fi enabled devices including cameras, such as the Nikon Coolpix and the Kindle, so with MiFi and similar technologies, you can connect any combination of these, up to five devices. You can follow this link for more information on 3’s MiFi device.

A portable Wi-Fi router is another option for sharing the net. These are now relatively inexpensive and quite straightforward to use. You simply connect to a mobile network and share with other devices. However, do shop around before choosing one, as some are better than others.

Internet connection sharing is another option. By connecting a laptop or PC to the internet, you can then share its connection with other devices. For example if you’re running windows 7 this can be done through the network and Sharing Centre, but can be quite complicated  to carry out so is really only useful for advanced users or those who have the time and patience to hit the forums and get step by step instructions.

With different operating systems it works slightly differently so you may have to look up how to do this on yours too, this can be something of a headache.

If you have a 3G enabled phone, you can connect to the 3G broadband connection and then share with other devices. So as long as you have a signal, you can connect to your laptop or another device. However, download speeds are often reduced and quite often you can’t get unlimited data, so if you are sharing a connection you could quickly reach your limit.

The new iPad will allow you to do the same thing, however, despite the device being initially offered as 4G, this technology isn’t yet available in the UK. 4G uses the old terrestrial TV signal waves and widens the spectrum for mobile broadband.

However, Ofcom will be auctioning off the spectrum later in the year and this should be available in 2013 with the top mobile operators and will give even more options for mobile broadband.

Ads online – you have a choice

2 Replies Christopher Roberts

The internet is full of ads. There is no escaping that fact that despite it being a free web, the word ‘free’ probably means you will have to put up with an awful lot of adverts. People who work online have to make a living, and ads is one of the most popular ways to do so – fair enough.

Sometimes you have to accept that we need ads to help keep so many free services on the internet running; information on blogs, free emails, forums and search engines just to name a few.

Many people believe that the ads are there, and that is the way it is going to stay. Useless information will get in your way when you are looking for useful content, but that is not entirely correct.

Advertisers advertise, ultimately because they want to boost their or their business or organisations income. Advertisements may drive sales, increase donations, raise awareness, promote a brand, offer freebies, or do a whole number of other things.

Most consumers (that’s people like you and me) think that adverts are an inconvenience, but need they be?

Advertisers are now getting clever, cookies are being used to track what you look at online, and are then used to present you with ads that are relevant to you, which you might actually find interesting.

Many people may find that a daunting prospect. Advertisers are collecting information about me in order to try to ‘improve my ad experience’ and at the end of the day get me to spend more money. Is that right?

Enter AdChoices.

The AdChoices IconThe Digital Advertising Alliance have founded a site called Your AdChoices, which gives you information about the choices you have about the adverts that you see whilst browsing the internet.

Would you rather the ads that you see online were relevant to you, or random? Now, for the first time, you have the ability to choose.

Hundreds of advertising hosts now use AdChoices, to let you personalise the way you view the web. Google, AOL, Adobe, Disney, Kraft, Microsoft, News Corp and Yahoo are just some of the big names that participate in the AdChoices scheme.

Here is an extract from the AdChoices website:

“The Advertising Option Icon gives you transparency and control for
interest-based ads:

  • Find out when information about your online interests is being gathered or used to customize the Web ads you see.
  • Choose whether to continue to allow this type of advertising.”

Still not understanding the concept? See if watching this video helps.

So you have a choice. You can choose to receive personalised ads, which could potentially improve your browsing experience, or you could choose to opt out. Your choice.

For more information, or to opt out, head over to YourAdChoices.com.

Sometimes, Technology Bloggers writers will choose to display an AdSense Ad in there articles. These all have the AdChoices button on them. I rarely add one, but for your interest, look below. Can you see the ‘i’?


What will you do, opt out or stay in? Do you think it is good that we are now offered personalised ads, or is it an invasion of privacy?

With regard to personalised ads I am undecided, but am slowly warming to the idea.
