      Difference Between SD & SDHC Memory Cards

      The Secure Digital (SD) memory card format was developed for portable devices across a wide range of product categories and is the unofficial industry standard for memory card format. SDHC is the high capacity variant of the memory card format. It has a slightly different communication protocol from the SD type and does not necessarily

      How to Measure Sound Quality

      There are many ways to measure sound quality. Many measurements have been created to specifically measure and rate the quality of sound. Here are a few of the most common types of measurements used for sound quality. THD THD stands for Total Harmonic Distortion. It is a measurement taken to view the total amount of

      USB Device Not Recognized

      A common problem that arises for computer users is dealing with the USB Device not recognized error. This error is thrown after an electronic device is connected to the computer or USB hub but is not automatically detected. When the error occurs, the Windows Device Manager may also list the component as an “unknown device”

      This Device Cannot Start – Code 10

      When someone receives the Windows error, “This device cannot start. Code 10 in audio driver,” it means that he/she has a bad, missing, or incompatible driver for his/her sound card. The very technical and confusing explanation for this message, according to Microsoft, is this: “If the device has a FailReasonString value in its hardware key,

    • CMOS RAM

      CMOS RAM

      When the computer boots up, certain amounts of information are needed to ensure that the computer boots properly. This includes hard disk types, keyboard and display type, chip set and the time and data. For example, the hard drive booting properly means that the operating system boots properly. This is important to understand because it

      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

      SPDIF

      SPDIF, or the Sony/Philips Digital Interconnect Format) is used to carry or transport digital audio signals in consumer electronic equipment such as CD and DVD players, PC audio cards, and car audio systems over short distances. The digital signal can be carried over fiber optic (TOSLINK connectors) or coaxial cable (RCA connectors) and is also

      AMD64

      AMD64 is a set of 64-bit extensions to AMD x86-compatible microprocessors. AMD64 extends the industry-standard x86 instruction set architecture while maintaining full compatibility with existing x86 applications. The 64-bit architecture of AMD64 enables applications to utilize up to 256 terabytes of memory, overcoming the 4 gigabytes limitation of 32-bit processors. AMD64 doubles the number of

    • Unbuffered Memory

      Unbuffered Memory

      Unbuffered memory, or unregistered memory, is memory in which no hardware register exists between a RAM chip and a memory controller. Unbuffered memory is not as stable as buffered memory, but is faster and cheaper to implement. While buffered memory may be necessary in some computer systems, such as high-end corporate servers and workstations, where
