With the release of Windows 7, the question was raised again on whether you should install the 32-bit version (x86) of the operating system or move up to 64-bit (x64).

The 32 or 64 bit architecture refers to the memory address length that can be referenced by the processor. This also has an impact on the maximum amount of memory that can be utilised, which is 4GB for a 32 bit CPU (but in reality the maximum accessible ram is often closer to 3.4 GB due to other hardware allocations such as graphics card memory).

Having a 64 bit OS doesn’t automatically make all applications faster because much of today’s software is written and optimised for a 32 bit era. You’ll need software specifically optimised for 64 bit processing to take advantage of any speed improvements. Fortunately, many games are already including such enhancements.

You may think that using a 64 bit OS for a 64 bit processer is an obvious decision, but it is not so straightforward. Introducing a new architecture will cause new compatibility and driver problems that wouldn’t exist under the old 32 bit version.

Pros and Cons of a 64 bit system:

  • You can address much more than 4GB of memory, which is ideal for avid gamers, CAD, video editors and heavy multi-taskers. However, any 32 bit software you use will still be restricted to 4GB memory – you need a 64 bit CPU, OS and applications to take full advantage of the extra RAM.
  • 16 bit applications will no longer run. Although this is unlikely to be a problem, if you use very old software (from the Windows 3.1 days!) then it will not work under a 64 bit OS.
  • Existing 32 bit drivers no longer work.If you have older or poorly supported hardware you may find that it can no longer be used. Got a 7 year old scanner that just about works in Vista? You may not be able to get it working in 64 bit Windows 7.
  • Unsigned kernel-mode drivers no longer work. Along with the issue above, the inability to run unsigned kernel mode drivers will cause problems for old hardware. (There is reportedly a way to bypass this check).
  • Running some 32 bit applications on a 64 bit OS could actually be slower. The additional overheads in running 32 bit software in 64 bit mode could cause a slight degradation in performance. It will take some time for 64 bit software to become the norm.

The conclusion? Well, it depends on what you use your system for. If you have a 64 bit capable CPU but use older hardware, it would be safe to stay with a 32 bit version for the time being to ensure that you don’t need extra upgrades.

If you’ve got the latest hardware and drivers are available, then it would be worth while taking the step up to a 64 bit OS. If you regularly work with resource hungry applications that are 64 bit optimised (such as video editing, CAD and image packages) then it would be especially beneficial to be able to work with over 4GB of RAM amongst the other improvements.

In the not too distant future, 64 bit computing will be a common standard – as all hardware from the last couple of years has been designed with this in mind. Until a complete upgrade cycle has passed for the majority of users, there is still a strong case for some users to stick with 32 bit Windows for the time being. Once more 64 bit applications start to appear, it would be a good time to make the switch to the new architecture.

………..Which one to Install..(*86) 32 bit…. or (*64) 64 bit????

This is something that’s been asked since the introduction of consumer-level processors bearing the “x64” nomenclature. It feels like just yesterday that Intel and AMD fanboys were at odds over the Athlon 64. At that time and even as recently as the introduction of Windows Vista, software and drivers for 64-bit setups were slim-pickings.

Analogous to the shift from 16 to 32-bit computing, the jump to 64-bit has been a slow one. Windows XP x64 never took off, though 64-bit versions of Vista did, thankfully. The ride was a bumpy one, but hardware manufacturers and software developers alike have finally widely adopted the 64-bit architecture – and there’s no turning back now.

At this point in time, nearly everyone is on the same page about the transition. If your old video card and printer have yet to receive 64-bit compatible drivers, odds are they won’t be getting any. A boatload of legacy hardware support was dropped with Windows Vista, and Windows 7 certainly won’t pick it back up, regardless of which version you install.


Now, you’re probably wondering why 64-bit operating systems are being phased in and what benefits they deliver over their 32-bit predecessors – both legitimate questions. One of the most commonly cited differences is that the 32-bit architecture has a memory access limit of 4GB (2^32 bytes). This permits you to use about 2.75-3.5GB of RAM after IO reservations are factored in.

On paper, the 64-bit architecture can address 16 exabytes of memory (2^64), or more than 4 billion times that of its precursor. Consumer editions of Windows Vista permit from 8GB to 128GB of physical memory to be accessed, depending on the version. Windows 7 bumps that up to 192GB with the Professional version and above.

Other benefits of running a 64-bit OS include enhanced security with hardware-backed DEP, Kernel Patch Protection and mandatory driver signing.

This is all just scratching the surface, but I suppose the real question should be:

Why shouldn’t you install Windows x64?

The short answer is that you should go with Windows 7 64-bit unless you’re running a system well into its antiquity where driver support is going to become an issue.



Did you know?
Retail versions of Windows 7 will include both 32-bit & 64-bit discs on the box in case you are undecided or prefer to make the jump to the 64-bit version of the OS at a later time.

....and thats I.T for you…

Technology Recap for 2011…

Technology Recap for 2011…

2011 was a huge year for technology! New devices hit the market, social media was used in revolutionary ways & old hats tried their hand at new things. Here’s our recap of the tech highs and lows of 2011…

1) Death of Steve Jobs:

This was certainly no highlight of 2011 but Steve’s untimely death gave everyone in the world a minute to think about his legacy. We re-read his wise words, discussed his demanding management style & daydreamed about Apple’s future without him.

2) Cloud Computing:

The cloud must be one of the most-used phrases of 2011. As more and more of us walk around with powerful computers in our pockets, more companies are finding ways to utilize the power of the cloud to expand their mobile reach.

3) Technology & the Arab Spring:

Tunisia, Egypt and Libya saw incredible revolutionary activity in 2011 & technology played a key role in the uprisings. Social media like Facebook & Twitter helped demonstrators organize organically and played an inspiring role in their move towards freedom.

4) Year of the Tablet:

Tablets were the it technology of the year. From the i Pad 2 to the Samsung Galaxy Tab, if you don’t own one by now, it’s likely that you know someone who does. Let’s not forget the Kindle Fire either, which marked a milestone with Amazon’s entry into the tablet wars.

5) Social Media Competition:

The success or failure of Google+ is still to be determined but Google’s attempt to challenge the blue giant was a bold move. By acting as a fusion of Twitter & Facebook, Google tried to draw users away from the latter; many have argued Facebook has too much momentum to face a real threat from G+.

6) Cyber Monday:

Online shopping got its moment in the limelight with Cyber Monday, the Internet’s answer to Black Friday. While not the first year that Cyber Monday has been hyped by online stores, this year it got a real boost & made a name for itself.

7) 3-D Phones:

Making the sci-fi dreams of decades ago a reality, 2011 saw the rise of consumer 3-D mobile phones & televisions. Glasses-free phones like the HTC Evo 3D took the dazzle of modern smart phones one step further, while Toshiba, Sony & Panasonic all manufactured 3-D TVs.

8) HTML 5:

The war between Adobe & Apple over Flash may finally be over, as Flash takes a backseat to HTML 5. Microsoft revealed in 2011 that aspects of Windows 8 wouldn’t support flash & Adobe announced that it would quit supporting flash for mobile devices.

9) SOPA Proposition:

As I write this, Wikipedia & several of my favorite blogs stand blacked-out, in solidarity against the SOPA antipiracy bill which was introduced to Congress in late 2011. This bill would give power to copyright holders to pull the plug on sites that link to copyrighted material (like Wikipedia). Critics say that enforcement of SOPA will be impossible & that the open web and all its resources will be irrevocably harmed if this becomes law.

10) High Profile Hackers:

2011 saw the Playstation network brought down for weeks by hackers, not to mention San Francisco’s BART transit system & Bank of America. Groups like Anonymous & LulzSec were behind some of the hacking; other acts weren’t attributed to particular groups.

With the arrival of 3 sub-marine cables, Kenyans thought that their days of poor internet connections is gone. That has been true to an extent. Only that now the country is experiencing persistent cable cuts affecting business in the country. AccessKenya is the latest victim with its main link cut on Monday and a day later they lost SEACOM backup link.

AccessKenya Group @accesskenyacom

“Kindly note that all our three connections btwn Nrbi & Mombasa have been cut.We suspect sabotage.We will keep you informed.Apologies!”

he company was relying on SEACOM link from Mombasa with the main line through KDN’s underground cable while the backup was through Kenya Power’s overhead lines. Now Access Kenya’s link from Mombasa to Nairobi is completely cut-off. Internet connection in Mombasa is ok.

Orange Kenya has sent out a press release saying that the cut is:

“affecting all internet traffic to Mombasa, GSM, CDMA and PSTN services. Due to traffic congestion customers may also experience interruption while making international calls.

Our technical teams have located the point of break and are on ground undertaking the repairs. Our estimated down time is 2 hrs. We are also currently evaluating alternate routing options aimed at easing the downtime as an interim measure.”

The SEACOM link delivered through the Kenya Power overhead cables was cut after one of the Kenya Power pylons got so weak and fell down while the KDN terrestrial link might have been cut by some contractors who are carrying out road repairs. Now only remaining reliable connection from Mombasa is the national fibre backbone which is owned by the Kenyan government.

Though Access Kenya is saying that its customers in Mombasa are ok, other ISPs are indicating that the cuts might affect the whole country as most of the network monitoring, billing and application systems are sitting in Nairobi and so all might be affected.

EASSy suffered cable cuts on February 17th when a ship dragged its anchor more than 100 metres on the ocean floor, cutting two other cables SEA-ME-WE3 (South-East Asia – Middle East – Western Europe 3) and EIG (Europe India Gateway). The two cables (SEA-ME-WE3 and EIG) does not server Kenya.

Being the largest private shareholder in the TEAMs cable, Safaricom was the most affected then. The company immediately switched to SEACOM and satellite for backup. Airtel Kenya launched its 3G network on 24th February and had to route their traffic through Telkom Kenya’s inland cable.

Safaricom’s Nzioka Waita yesterday indicated that the full repairs of the cut sub-marine cables might be finished by the 24th March. The repairs are carried out by a contractor, eMarine repairs.

With Safaricom serving around 80% of the national internet connection, the country has not felt it much but with now Access Kenya down, we will soon start seeing the effects. Access Kenya serves around 40% of corporate data needs in the country.

Now Safaricom routes its M-Pesa traffic which relies on cloud servers located in UK, through Satellite.

Repairs of terrestrial cables takes just hours meaning that connections might be back by the end of the day. The only problem is with the sub-marine cuts. With two cables affected, a cut on SEACOM’s sub-marine link will be catastrophic. Most ISPs removed all satellite backups.

A fourth cable, LION2 is looking for a landing point at the Coast as the government has issued a directive demanding that future cables should not land at the same point.

UPDATE: Access Kenya is indicating that its link is now back online. I also received information that the vandalism of KDN was carried out at JOMVU. Telkom Kenya’s link affected by excavators.
