Desktop Computers Destined for the Scrapheap?

The IBM Personal Computer (PC) was thirty years old last Friday, and according to those in the know, it might not be around for much longer. A blog post by Dr Mark Dean, one of IBM’s longest serving and most respected computer designers (who helped build the classic IBM 5150) has been making big waves across the technology sector after he claimed that the PC was heading in the same direction as vinyl records and the typewriter, light bulbs and the vacuum tube.

Dr Dean points out that PC’s and cheap laptops have had their time and place but that now they have helped to create a world which needs a new type of device depending on use and form.

Claiming that he himself has moved beyond the PC and only works on a tablet, he notes that PC’s will still be around a while longer but that “they’re no longer at the leading edge of computing.”

He goes on to say that it will not only be tablets and phones that cause the demise of PC’s but also a change of mindset about the place of computing in society and the progress of man. Instead of being about computing they are now a way of facilitating innovation not on the devices themselves, but “in the social spaces between them, where people and ideas meet and interact.”

When IBM released the 5150 in 1981 it soon set the standard for how PC’s were to look and operate. The computer, which had a massive 16k of ram and cost more than $1,500 was one of the computers that began the ‘PC Era’, that revolutionized the way we work and live.

According to Dean, such a revolution is also underway once again. He is not alone – in another blog about the 30th anniversary of the PC, Microsoft’s Frank Shaw argued that the proliferation of tablets, phones and other such devices was the beginning of a new ‘PC Plus Era’, if not necessarily an indication of the end of the PC and traditional computer devices.

So what do you think? Are you ready to ditch that PC just yet?

All about cloud computing

What is cloud computing?

Cloud computing is the management and provision of data and applications via the internet. In non technical jargon that basically means is that it is the storing your programs and documents on the internet, rather than on your computer.


What is an example of cloud computing?

If you watch the tv, you will probably have seen those adverts that promote laptops and phones which allow you to work anywhere because of the ability to store your data in the cloud.

This basically means that your device merely holds the operating system and sometimes the software. The date you access is stored on a server somewhere. This means that you can access your data from almost anywhere with multiple devices.

The good and the bad…

As with most things in life, cloud computing has positives and (you guessed it) negatives. Here is a list of the pros and the cons of cloud computing:

The Pros

  • Less hard disk space needed
  • Your computer runs much faster – like the Chromebooks are meant to (this is dependant on your internet connection)
  • You can access your data from anywhere at anytime
  • Most providers of cloud services, regularly backup your data, meaning if you loose some data or if they loose some, it shouldn’t be too hard to recover
  • Avoid costly hardware (and to some extent software) upgrades

The Cons

  • If your internet dies, you can’t access your data, and in the case of a Chromebook, you can’t even access your programs
  • Some security risks are removed (like if your PC is stolen, someone may steel your data too) but loads of new threats from corrupt employees, hackers etc. are born
  • The services (initially) probably won’t be as reliable as you would like them to be
  • Big brother is watching you! – every move you make online or in a cloud based application can be monitored by your provider
  • You need a really fast internet connection, both download and upload, to really feel the benefit of it – the problem is, most peoples download speed is really fast, but their upload speed is rubbish!

Where is cloud computing data stored?

Good question – presumably not in the clouds! Applications, data etc. would be stored in server farms. Server farms are massive, usually very cool (air conditioned to increase machine performance and to prevent overheating) areas, full of loads of server towers.

Google, Facebook and similar massive sites generally have their own server farms, which they often store underground, and they make sure that they are very well connected!

What’s your opinion on cloud computing? Is it the way of the future, or will it do more harm than good?
