To fully understand this, you need to read up on logic gates, boolean algebra, CPU and bus architecture. I'll try to keep it simple. The base language of a computer is machine code. The part of the computer that actually "understands" and executes machine code is the CPU. Machine codes consist of numbers: opcodes and arguments. For example "254" is a x86 instruction meaning "decrease by 1". The CPU itself consists of a complex network of logic gates (basic digital devices that combine and manipulate bits of data). When the CPU reads an opcode of 254, it sees it as a binary bit-pattern: 11111110. Each of those bits is sent down its own wire (bus) into a logic-gate network (instruction decoder) which is connected in such a way that an input of 254 would activate the "decrease by 1" mechanism; an input of, say, 14 would activate the "multiply by" mechanism, etc. In short, the CPU is hardwired to respond to specific patterns of bits which we call machine code. If you ever take a digital circuit course, you will likely build a basic 4-bit CPU for your final project. It's hard to clarify this to someone who's had small experience with digital logic circuits. To fully be with you this, you need to read up on logic gates, boolean algebra, CPU and bus architecture.

probally multiple servers

your hardware would not be located at your house

it would be rented in a datacenter…

visit hostway for a better thought

but you still need the programming to run the engine not just the server

NVidia's been having some trouble lately, and AMD has been doing an amazing job with their Linux drivers. Even better, AMD's moving ATi to an open source model (they're just working out licensing) so I'd recommend an ATi video card. The latest drivers from AMD even support redirected rendering for 3D on a 3D surface (like the cube), and Ubuntu Lucid Lynx, due out in April of next year, will have DRI2 (again, redirected rendering) working on the open source Radeon driver. 2. Your biggest issue will be a printer. HP and Epson are both very well supported. For other brands, check before you buy. Personally, I love my Epson. 3. Wireless shouldn't be too much of a problem. Just find what chipset the wireless is using, and you should be OK. Ralink, Atheros, Intel, and Broadcom are the most common, and should work fine. 4. TV Tuners, IR receivers, and Bluetooth devices will be your odder ones to find. That said, it's about as difficult getting ones with good Windows support. If you are looking for one of those components, I'd recommend asking a specific question. Good Luck, and have fun with Linux! I know I do every day, and the best part: It has so far run just fine on every computer I've stuck it on! Even the Bluetooth on this Netbook, and the RaLink wireless on my MSI, the weird Radeon with dual-DVI on my Dad's desktop, and the totally random WiFi card in my friend's desktop. Just about any hardware will work fine, but I can give you some tips.

2. Your largest issue will be a laser printer. HP and Epson are both very well supported. For other brands, check before you buy. Personally, I like my Epson.

3. Wireless shouldn't be too much of a problem. Just find what chipset the wireless is using, and you should be OK. Ralink, Atheros, Intel, and Broadcom are the most common, and should work fine.

4. TV Tuners, IR receivers, and Bluetooth devices will be your odder ones to find. That said, it's about as hard getting ones with excellent Windows support. If you are looking for one of those components, I'd recommend asking a point question.

Excellent Luck, and have fun with Linux! I know I do each day, and the best part: It has so far run just fine on each computer I've stuck it on! Even the Bluetooth on this Netbook, and the RaLink wireless on my MSI, the weird Radeon with dual-DVI on my Dad's desktop, and the really random WiFi card in my friend's desktop.
