Processor: Core i5 2.5 GHz
The processor is like the central nervous system of your computer. The processor interprets and executes commands; Which processor you have essentially defines the card's capabilities. Similar processors come in a variety of speeds.

Installed Memory: 4 GB (DDR3 SDRAM)
Installed memory is also known as installed RAM. RAM, or Random Access Memory, is the place in a computer where the operating system, application programs and data in current use are kept so that they can be quickly reached by the computer's processor. The amount of RAM you have affects how quickly you will experience your computer working.

Hard Drive: 320 GB Serial ATA, 7200 RPM
Hard drive is the computer hardware that contains an optical and/or magnetic disk, which it both writes and reads data on; it stores all electronic information and software programs, making it one of the most important components of a computer. Hard drive capacity is measured in bytes, both megabytes (MB) and gigabytes (GB). 1 GB equals 1,024 megabytes. Standard hard drives range from 40 GB to above 120 GB. 40 GB has become the standard for PC hard drives. Those who DON’T use their PC to manage their day to day activities or download a lot of new software programs, photos or other items that take up space would be fine with a standard capacity hard drive. Those who DO perform all the previously mentioned activities should buy a PC with a greater hard drive capacity.
