      CPU (Central Processing Unit)

      CPU is an acronym that stands for central processing unit. The central processing unit is responsible for performing all of the mathematical calculations that are required for a computer to function properly. Because a computer cannot function without the CPU (which may also be referred to as the central processor or just the processor), it

    • DASD (Direct Access Storage Disk)

      DASD (Direct Access Storage Disk)

      A DASD, or Direct Access Storage Disk, is a type of storage device that is connected directly to a user’s computer rather than being connected to the network. Because many types of storage device connect directly to a user’s computer, the term “DASD” may apply to a variety of different devices; however, a DASD is

    • Dielectric Grease

      Dielectric Grease

      Dielectric grease is a translucent substance used to seal electrical conductors in order to prevent dirt, dust, sand, and other foreign materials from sticking to the conductor and preventing it from transferring a current between the two contact points. Dielectric grease also blocks moisture, thereby preventing corrosion. How Dielectric Grease Works Dielectric grease is a

    • iSCSI vs NAS

      iSCSI vs NAS

      iSCSI (Internet Small Computer System Interface) is an IP-based storage networking standard that allows users to access data stored on a remote server from a number of computers within a specific network by linking computers over the Internet. It transfers data over local area networks, wide area networks, and the Internet. iSCSI places a shortcut

    • USB to Ethernet Adapter

      USB to Ethernet Adapter

      USB (Universal Serial Bus) is a hardware specification that allows a connection to be established between a source device and a peripheral device. Most modern electronic devices include at least one built-in USB port and can use USB technology to connect to other devices, such as keyboards, mice, cameras, flash drives, external hard drives, printers,

    • Fingerprint Scanners

      Fingerprint Scanners

      Fingerprint scanners are biometric security systems designed to use the distinct features of an individual's fingerprints to provide security. Fingerprint scanners are now being used in police stations, security-intensive industries and, most recently, on computer shops as a peripheral device for computers. Biology of a Fingerprint Every person has marks on his fingers. These marks

      SDIO (Secure Digital Input/Output)

      The Secure Digital Input/Output card standard expands upon the original Secure Digital card standard, extending the functionality of many devices with SD card slots. The Secure Digital Input/Output card standard is based on the Secure Digital standard. The SD flash memory format was designed purely for portable storage; many cell phones, cameras, GPS receivers and

      How Do Quad Core Processors Work?

      A quad core processor is a piece of hardware made up of three components. The first is the core, which in this case, there are four of them. Then these are bundled up and fit inside a die. The die is the silver tab you might see on your processor. Finally, this is added to

    • Blu-Ray

      Blu-Ray

      Blu-ray is an optical storage format developed by Sony and Phillips. It was created to store large amounts of high definition video and sound. Blu-ray’s name came from the type of laser it uses to read and write data. The laser is a hue of blue-violet. A blue-violet laser has a shorter wavelength than the

    • The Difference between Bit Rate and Baud Rate

      The Difference between Bit Rate and Baud Rate

      The difference between Bit and Baud rate is complicated and intertwining. Both are dependent and inter-related. But the simplest explanation is that a Bit Rate is how many data bits are transmitted per second. A baud Rate is the number of times per second a signal in a communications channel changes. Bit rates measure the
