Random Access Memory – RAM. Where information is stored temporarily when a program is run. Information is automatically pulled into memory‚ we cannot control this. RAM is cleared automatically when the computer is shutdown or rebooted. RAM is volatile (non-permanent). b. Read Only Memory – ROM. More permanent than RAM. Data stored in these chips is nonvolatile -- it is not lost when power is removed. Data stored in these chips is either unchangeable or requires a special operation to change

How it’s made: Computer LCD Monitors Today‚ computer monitors are a vital part of a person’s life. It is a part of your basic desktop bundle‚ and without it‚ you wouldn’t be able to use your computer‚ unless‚ of course‚ you use your T.V as a monitor. Computer monitors are tremendously made as liquid crystal displays. They are used because they are thinner and lighter and use much less power than cathode ray tube monitors. LCD computer monitors are made in a specific and special type of way.

4. Computer Hardware Image Gallery Graphics cards take data from the CPU and turn it into pictures. See more computer hardware pictures. The images you see on your monitor are made of tiny dots called pixels. At most common resolution settings‚ a screen displays over a million pixels‚ and the computer has to decide what to do with every one in order to create an image. To do this‚ it needs a translator -- something to take binary data from the CPU and turn it into a picture you can see. Unless
