What harddrive has more space and/or speed: Gigabytes or Terrabytes? What is biggest Gigabytes Terrabytes.?

What the advantages and disadvantages between the Gigabytes and Terrabytes?

What processor is the fastest and the best motherboard?

I would just like to use a the fastest computer with more memory and cache, ets term which I'm not familiar with; because, I am not a computer wizard/technician or programmer not a Computer Engineer.or Information Technology Graduate. I am retired public elementary school teacher who is planning to make my home a business center on line with any products available in the world wide web of the internet.

You don't need 'the best' or 'the fastest' to make a business center out of your house. You'll want a desktop with anywhere from 300 or more gigabytes of hard disk space (terabytes are bigger than gigabytes, and you don't need a terabyte hard drive). You'll want a processor which is at least 2.2gigaherz (not to be confused with gigabytes, gigahertz refers to the number operations your computer can do per second, whereas gigabytes refers to the amount of space you have on your computer). However if the computer you're looking at has a 'duo' core, it basically has two processors built in, so if it's only say 1.7gigahertz, that's fine.
You'll want at least two gigabytes of RAM, more than three or four would just be silly.
You shouldn't need anything more than the default graphics card unless you're planning on playing video games, which it doesn't sound like you'll be doing much of, so that's fine.

I personally really like HP and Compaq computers, so I would suggest buying a midline computer from either of them.

Now, all that said, this has nothing to do with having an online business. You'll obviously need a computer, but completely separate from that you'll need to hire someone to build, maintain, and manage your website for you.

And here begins the shameless plug: Luckily enough, I have been building websites professionally for about three years now, and if you're interested, you're welcome to visit my website, DigitalGemstones.com, check out some of my past and present work on the clients page, and send me an email, I would be happy to build and maintain a website for you.

bits
bytes
kilobytes
megabytes
gigabytes
terabytes
petabytes

Terra bytes is defiantly the bigger one...

I would say the Fastest Processor at the moment is the
Intel Core 2 Quad
as it has 4 processor cores to it.. so its like 4 of them in 1
Try finding a computer with that processor as that's the way there heading for processors...
yeah you should probably just buy a business computer from someone like gateway.

Gigabytes are 1 Billion bytes, Terabytes are a 1024 Gigabytes.

Problem with Terabytes? How to back them up?

Intel processor??? Probably the latest quad core QX9750 or so.

You don't need a fast computer unless you are doing games or rendering graphics or serving many users.

I would suggest you buy a business computer from Dell or HP to start if you want a reliable machine.
