All PCs store data to the hard drive and the random access memory (RAM). The computer loads active data into the RAM for faster data processing, and saves long-term data, like user files, to the hard drive. The more RAM a computer has, the faster it can perform. The more storage space a hard drive has, the more data it can store. To determine the hard drive’s specifications, use Windows 7’s built-in informational tools. To determine your memory’s specifications, you can go to the Crucial website (www.crucial.com) and use its no-cost system analyzer.
