I do a lot of answering questions concerning computers and computer hardware online and there is one question that has come up more than once. As such, I figured I would include it here in case any of our visitors have the same question.

The question concerns computer processors and what all those terms mean when you see a processor description. CPUs, or Central Processing Units, technically have 12 specifications, including things like Brand, Type, Series, Socket Type, etc. However, honestly, only 3 specifications really matter when it comes right down to it. They are, Frequency, L2/L3 Cache, and FSB, or Front-Side Bus.

Frequency: CPU frequency, or Clock Rate, is the rate that a processor cycles 'on and off' to process incoming requests. It is the biggest indicator of how fast a processor really is. The higher the frequency, the faster the processor processes.

L2/L3 Cache: L2/L3 Cache are memory locations built into the processor that it uses to store incoming requests until it has the chance to process them. This memory type is extremely fast, much faster than a computers RAM is. The larger the cache the better because it means that the processor does not have to go to the RAM as often to pull requests. The reason for the L2\L3 is because some processors have two such cache locations.

Front-Side Bus, or FSB: FSB is the 'bus' that carries the data from the CPU to the Northbridge chipset. The Northbridge controls the RAM and Video Card processing. So, essentially, the higher the FSB speed, the more bandwidth the system has to transport your requests out to the other components of the computer. These specifications are also per core. So, when you find a processor that is Dual-Core, or Quad-Core, etc, these specifications apply to each core individually.

Computer processors are extremely complex devices and the above descriptions are highly simplified. Entire books have been written concerning CPU specifications but hopefully this simplified explanation helps answer questions you may have had about what these terms mean.

Forget Myers-Briggs. Here are the true archetypes that underlie the IT breed

In the workplace you'll generally meet three kinds of personalities: Type A, Type B, and Type IT. The last are a breed apart from the rest.

We're not sure what it is about technology that draws certain types of people while repelling others. Maybe it's all those electrons spinning through millions of miles of circuitry; maybe it's just the lack of sunlight and human interaction.

In any case we've identified the eight classic personality types you'll find in virtually any reasonably sized IT department. Some are suits who've been exiled to IT against their will or sharks who would happily sell ice to the Inuits once they got done selling sand to the Saudis. Others are of the more typical geek persuasion -- from scary system administrators and angry support drones to those who'd rather blend into the shadows or do their best to shoot down any project that ventures inside their crosshairs.

We bet many -- if not all -- reside in a nearby cubicle at this very moment. Consider this your field guide to the flora and fauna of your work life.
