Processor Speed

Installed Memory Usually used in reference to the system RAM (Random Access Memory). RAM comes in the form of chips and is used to temporarily store information. It can be written to and read from, and is measured in Megabytes (MB) or Gigabytes (GB). 1 GB = 1024 MB. Common memory technologies in use today are SDRAM, DDR-SDRAM, and DDR2.

Hard Drive Size The Hard Drive is the main storage device. Information is written to a magnetic disk to be retrieved at a later time. The amount of information that can be stored on a hard drive is measured in Gigabytes (GB). The speed of the drive is measured in RPMs (Revolutions per Minute). The higher the RPMs, the faster the hard drive can transfer information.

Processor

Bus Speed How fast data is transmitted from one part of the computer to another. Measured in MHz, megahertz. The higher the speed the faster your applications run.

Cache Size

Processor Speed Processor speed is measured in either MHz or GHz, where 1000MHz is equivalent to 1GHz. It is a measurement of how many cycles the processor can complete in one second and generally the higher the value, the faster it can complete a task.

Processor Class One of the most important components of any computer system, the processor performs the system computations. There are two companies that produce the majority of the processors on the market: Intel and AMD. Each company manufactures a number of different processor series.
