      Hard Disk Partitions

      A hard disk partition is a defined storage space on a hard drive. Most operating systems allow users to divide a hard disk into multiple partitions, in effect making one physical hard disk into several smaller logical hard disks. Reasons to Use Hard Disk Partitions A user may decide to split a hard disk into

      How to Format a Hard Drive

      Formatting a hard drive often becomes necessary when Trojans or viruses that are difficult to remove infect it or when there are bad sectors on it. A hard drive should be divided into small partitions to utilize the space effectively. A hard drive can also be formatted in order to reorganize the space available. Remember,

    • ATX Power Connector

      ATX Power Connector

      ATX (Advanced Technology xTended) is a specification for motherboards created by Intel in 1995. It has replaced the AT standard and it is now incorporated into a wide variety of computer systems as the default motherboard layout. Although ATX is still very popular today, the microATX, FlexATX, and mini-ITX motherboard specifications have replaced it. The

      How an Uninterruptible Power Supply Works

      An Uninterruptible Power Supply (UPS) is a device connected between the power source and a computer to ensure that electrical flow is not interrupted. UPS devices use batteries to keep the computer running for a period of time after a power failure. It is not to be confused with standby generators which do not provide

      SIMD (Single Instruction Multiple Data)

      SIMD (Single Instruction Multiple Data) is a computer science method of combining multiple operations into a single computer instruction. The total number of operations combined is normally a factor of the power of two. The employment of SIMD results in significant savings in speed for algorithms designed to work in parallel. The technology is used
