    • Mirroring


      Mirroring is the automated process of writing data to two drives simultaneously. Mirroring is used to provide redundancy, backup, multiple concurrent accesses and uninterrupted accessibility. If one drive fails, the redundant drive will continue to store the data and provide access to it. The failed drive can then be replaced and the drive set can

    • DMA (Direct Memory Access)

      DMA (Direct Memory Access)

      DMA stands for Direct Memory Access, a capability in modern computers that allows peripheral devices to send data to the motherboard’s memory without intervention from the CPU. The DMA controllers are special hardware – now embedded into the chip in modern integrated processors – that manage the data transfers and arbitrate access to the system

    • Random Access Memory

      Random Access Memory

      Random-access memory is a type of data storage for computers. Commonly known as the acronym RAM or simply memory, random-access memory details the speed in which data that is stored can be accessed at random. This means that the strength of the RAM determines, at random, how fast a piece of data can be pulled

      What is a Hydrophone?

      A hydrophone is a type of microphone that is specifically designed to be used under water. Hydrophones depend on piezoelectric transducers to detect sound waves and other pressure waves coming from underwater vehicles, animals, and natural structures. Hydrophones were widely used in World War I, and II to detect U-boats (German submarines) and are still

      How to Setup Dual Monitors

      Using dual monitors refers to using two physical display devices to increase the viewing space running on a single computer. Microsoft Windows Operating Systems and Mac OS X now support dual and multiple monitor configurations. Setting up dual monitors is easy. However, it requires the user to add a second video card or install a

      What is a Biometric Coprocessor?

      A biometric coprocessor is a device that is capable of scanning a user’s physical attributes in order to allow access to a building or computer network. A biometric coprocessor is essentially a fingerprint reader, but may also include sensors that analyze the user’s eyes, voice, or even breath. The term “biometric coprocessor” comes from the

      How to Reset an IBM ThinkPad BIOS Password

      An IBM ThinkPad laptop can have three hardware password sets: Power-On Password Hard Disk Password Supervisor Password Power-On Password RT/CMOS RAM has 8 bytes reserved for the power-on password and the check character. The 8 bytes are initialized to hex 00. The microprocessor can access these bytes only during POST. After POST is completed, if

      Flash Memory

      Flash memory is a nonvolatile memory type that is constantly-powered. It has the capability to be reprogrammed or erased in various units of memory referred to as blocks. The technology is based on EEPROM (erasable programmable read-only memory) that is written and erased at the byte level which operates at a much slower rate than
