The great mystery of the PC is what takes place inside its circuitry .How can this box of chips, wires, and other parts -most of which don't move- do its work?
A processor's performance -even its capability to function- is dictated by its design, or architecture . A chip's architecture determines where its parts are located and connected, how it with other parts of the computer, and much more. It also determines the path that electricity(in the form of moving electrons)takes as it moves through the processor, turning its transistors on and off. There are many different chip architectures in use today, and each family of PC processors is based on its own unique architecture.
In fact, processors are differentiated by their architecture. The processors of IBM PCs and Macintosh computers have such different architectures, for example, that they cannot even run the same software; operating systems and programs must be written to run on each processor specific architecture, to meet its requirements.
A processor's architecture determines how many transistors it has, and therefore the processor's power. Simply stated, the more transistors on a processor, the more powerful the it is. The earliest microprocessors had a few thousand transistors. The processors in today's PCs contain tens of millions. In the most powerful workstations and server computers, a processors may contain hundreds of millions of transistors. When a computer is configured to use multiple processor, it can ultimately contain billions of transistors.
A processors includes many other features that affect its performance. For example, a processors performance is affected by the number of bits of data it can process at any one of time. Currently, nearly all standard PC processors move data in 32-bit chunks; they are called"32-bit processors". In 2003 American Micro Devices(AMD) released a new generation of desktop PC processor that can handle 64-bits of data .(High-end workstations and many minicomputers systems have used 64-bit processors for about a decade).

Everyone loves digital cameras and the ease of operating without film, but storing all the images can be an issue. At home I like to store them on my laptop and back them up to CDs.
If you are going on vacation for a week and plan on taking lots of pictures, you should know how many images you can you store on your laptop.
Most consumer shoot in compressed JPEG mode, and the images are between 250k bytes and perhaps 1.4M bytes. A 1 GB CF will hold as many as a thousand or more images. If you are like me it is easy these days to shoot a lot of pictures in a very short time. You could buy another CF or transfer the images to your laptop.
Laptops do not hold all that much data. How many gigs of disk capacity do you have left on your personal laptop? The newer ones will come with 40 or even 100 GB drives, but most people don't have ones that new, and many also have a bunch of stuff loaded already. So, check out the size of your HD and see how much space is left for your photos. If your laptop has a CD burner bring extra blank CDs so you can burn the photos. A great little back tool is http://www.secondcopy.com. You could also back them up to your ISPs server.
Another option might be to buy a portable hard drive. You can find them the size of good-sized glasses case. You stick your CF in a slot, turn the gadget on, and dump the CF into the gadget's storage. These range from 20GB to 60GB+ and are $100+.
Stand-alone burners can burn CDs & DVDs, and some will also play DVD movies, audio CDs, etc as well so you can bring your movies and music along while traveling.
If you have a new laptop it might have a fast firewire connection, if not you will need to use the USB connection to transfer the photos.
So, taking a few precautions and planning ahead a little will insure that you get to keep all the photos that you took as a reminder of that wonderful, long ago vacation.

Laptop computers or notebooks are of course used all over the world for business and pleasure. Aren't they so expensive though. You needn't always go on the hunt for a laptop - sometimes you just know a bargain price when you see one.
Lots of high street stores sell them, small shops sell them, friends sell them, almost anyone sells them, but where's the best place to get yourself an excellent laptop?
Where do we start then? My guess is as good as yours I could say. But I'll try not to say that.
If you're fairly new to the laptop world then probably the first thing you need to know before purchasing is how much space (gigabytes) you'll need for your information - you know, stuff you might store, stuff you might write yourself etc.
Then, if you're like me, the next most important thing is price! Quality as well yes, but price is what we all look out for isn't it.
Amazon is a superb place to get your laptop or notebook. You can get them brand new, refurbished or even second hand if you like.
They have a huge selection of laptops at amazing prices. Before you buy, Amazon will give you all the information concerning the laptop that you will need. They also give you feedback from other people which is great because then there's no bias. It really is an excellent way to purchase your laptop for business or pleasure.
Very importantly, you will be able to shop with Amazon using their payment facility with secure encrypted payment, so no need to worry about paying online.
Fear not, buy that superb laptop you want or need and get the best deal available.

If you are looking for a used computer, you can save a lot of money. However, there are some very important factors you should take in to consideration before purchasing the first used computer you see. As with all things, a rash purchase can often lead to regrets down the line.
The best advice anyone can follow when shopping for a used computer is to make sure you have a knowledgeable friend at your side who can tell you what is a good deal and what is not. The computer should be given a complete physical inspection to look for damage and glitches. Make sure that you and your friend check for problems and not a salesperson. You should also make sure that the sale you are about to purchase includes the original operating system software discs and manuals. You should have the manuals, discs and licenses for any and all software applications and fonts on the machine.
Remember that computers depreciate quickly, so find out the value of the computer as it is now and not when it was new. You can check out used computer sales on the Internet to see what people are paying, but keep in mind that there is no real true source to find out what a used computer should cost.
Last but not least, make sure the computer you are purchasing is legal. There are hundreds of “hot” (stolen) computers out there in the hands of thieves that would love to get their hands on your money.

The greatest advantage of laptops is that they are portable, so businesses on the move are their biggest fans. However since laptops are more expensive than desktops, it becomes wiser most of the time to rent them.
Companies rent laptops during trade fairs or seminars, outstation presentations or employee training. Even if a company has its own computers, it is better to rent a laptop as these are wireless devices and can be taken anywhere. Laptops are lighter in weight and use LCD displays. Laptops are also the answer when the need for a computer arises at a short notice, or for a short length of time. Temporary offices that are set up, like during the construction of a building, may be totally conducted from a makeshift office with rental laptops. Laptop rentals are in demand during news coverage at a particular area, such as in the aftermath of a disaster.
Renting companies most of the time take care of the entire setup. Setup includes installing the appropriate software on the laptop and checking for Internet connection. It is better if the renting company is informed in advance of the software needed. Users are required to check the functionality of the laptops. However. some rental companies only ship the equipment leaving the set up to the user.
Renting laptops is a very easy process. There are several online companies that provide rentals. They can be paid for by check or by a company credit card. There is no binding on the rental period. A company may either terminate the rent before the period ends or extend it as per their need. There are penalties for either early termination or extension.
Laptop rentals are also economical as these may be tax deductible. Most laptop companies have warranties on their equipment ranging from 45 to 90 days.
