Computer Basics

            When we mention the word "technology" one will instantly think about computers and computer science. The fact is computers are everywhere and in all parts of our lives. Everything from our cars to our pharmacy has very important parts done by microprocessors. I'll, however, just be talking about the personal computer (PC). I'll be talking about the technical parts of a PC, using computers in business, the internet, and gaming. .
             The CPU (central processing unit) is the heart of your system. The CPU is the brain of the PC and oversees everything the PC is doing. The best and most powerful CPU out right now is Intel's Pentium 4 3.06 GHz chip. If you want fast PC processing your going to want a fast CPU. A faster CPU means quicker response times, faster loads, and better multi-tasking. A brand-new P4 3.06 CPU will cost you about 620 dollars.
             Memory is a very fast storage of PC data. It's fast because it has a direct connection to the CPU. Memory is extremely useful as things can buffer into the memory instead of streaming off of the hard drives. The more memory the more data can stream in and the faster the PC will run. There are several different types of memory and all serve different purposes. Random-access memory (RAM) is used to temporarily store information the PC is currently working with. RAM is emptied out and refreshed every time the PC is rebooted, or through 3rd party cleaning agents such as Memturbo. Read-only memory is permanent storage for information needed by the PC every time it's used, such as your start-up information and your Basic Input/Output System (BIOS) settings. Most BIOS programs use a standard set of beep codes at start-up. A single beep means everything is in order and working as it should. Caching is an extremely fast storage center connected to the CPU. Caching is faster than RAM, but is smaller in capacity. Virtual memory is a temporary space on the hard drive used to store data and switch it out with RAM as needed.
