Computers as Brains :P

Being that the last post I made was in April and it is now nearly July, those of you that know me might be willing to bet that I didn't wait this long to start building this computer. Alright, so this monster is complete and I haven't been willing to pull myself away from the fun of tweaking and toying with it long enough to put together a coherent post. So I figure there's no better time to make the attempt than today!

A computer needs at least:

1. A CPU (Central Processing Unit) - As the proverbial 'Brains' of the computer, the CPU performs a great many number of calculations in a very short period of time. Click HERE for a better collection of info and explanation that I can give. 
2. RAM (Random Access Memory) - It can be thought of as the short-term memory of the machine. As the CPU rips through its calculations it needs a place to store the new information, especially if it will be needed again soon for other calculations. Information comes and goes from the 'short-term' memory much faster than it would to commit it to the 'long-term' memory making it ideal to keep up with the speedy CPU. Click HERE for the wiki.
3. Hard Drive (Storage) - This would be the long-term storage. Information written to the Hard Drive won't be lost if the computer is powered down like it would be in the RAM. However, relative to CPU speeds, it seems the equivalent of FOREVER to write information to the Hard Drive, which means that only information worth remembering is committed to the 'long-term' storage. Click HERE to learn about the basic idea, and HERE to learn about Solid State Drives (same but different).
4. Video Card/Controller - If we are going to stick to my analogy, this component would be the computers' Visual Cortex. At its most basic function, it will take information from the CPU and translate it into a video signal for a monitor or TV. The Video Card/Controller is responsible for rendering 3D objects and displaying them. Click HERE to read the Video Card wiki.
5. Sound Card/Controller - Best described as the Primary Auditory Cortex, this component will take information from the CPU and translate it into a sound signal for speakers or a receiver. Basically it is the sound equivalent of the video card. It also handles translating an analog sound signal from a microphone to digital information that can be stored. Read about it HERE.
6. Motherboard - Well, I may be grasping at straws but I'm thinking that this might be analogous to a collection of Neural Pathways. In the same way that Neural Pathways connect one part of the brain to another, the motherboard connects shuttles information from one component to another. The CPU, RAM, hard drive, video card, and sound card are all directly connected to the motherboard. For example, the motherboard could move information such as that contained in a video file from the hard drive to the CPU, then from the CPU to and from the RAM, then from the CPU to the video and sound cards.

7. Power Supply - Alright, we're moving away from the brain! The power supply would be the heart of the computer body. While it takes no part in processing information, it provides (pumps) electricity (BLOOD!!!) to the CPU (Brain) and other components (Other brain parts!) in order to allow them to function and process information. Detailed Power Suppy info is HERE.
8. Computer Case - The brain and its supporting components are a fragile lump of tissues that need protection that only a skull can provide. Like a cranium, the computer case provides a protective home for all the components. Computer case info HERE.

So without further adieu (French for delay?...) I'll sum up the details of the starter pack I put together over weeks of my researching and learning. 

1. CPU - The AMD FX-8120
2. RAM - Corsair 'Vengance' 16gb 1600Mhz
3. Hard Disk - Seagate 1tb Hard Drive, Patriot 60gb SSD
4. Video Card - Sapphire 6850 - 100315L
5. Sound Controller - Onboard 7.1 HD Audio (incl. on motherboard)
6. Motherboard - Gigabyte GA-990FX-UD3
7. Power Supply - PC Power & Cooling 750W powersupply
8. Case - Raidmax Blade-White case

In retrospect, the easiest part of building a computer is putting it together. I find that researching components and planning a design with components that makes sense for the applications to be the brunt of the work. However, putting it together is easily the most fun! In my next post, I'll share some pictures of the cool computer parts as they are placed together in their skull.
