      Types of Computer Cases

      A computer case, also termed as computer chassis or cabinet, is a small enclosure or box into which all the major computer components and peripherals are fitted. Computer cases can be broadly classified into 2 different categories. Each of them is briefly discussed below. Desktop Case: Considered the most classical version of computer cases, these

      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

    • Firewire


      Firewire, also known as IEEE 1394 and i.Link, is a high speed serial bus developed by Texas Instruments and Apple computers in the mid 1990s. Firewire is compatible with more than 63 electronic and digital devices, which makes it a great choice for many people. Technically speaking, Firewire is a PC serial bus interface standard

      NAND Drives

      NAND drives are high-capacity, high-speed, solid-state flash memory drives. Thanks to new advances in technology, these drives have been chosen to become the latest drive preference for laptop computers (hopefully in the near future). When comparing the NAND to other types of flash memory, NAND drives have several noteworthy advantages. The term "NAND" refers to

    • 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

    • CAS Latency

      CAS Latency

      CAS latency is short for Column Address Strobe latency. CAS latency is the time (in clock cycles) required to access a column of memory on a DRAM memory module. A CAS3 rated memory module requires 3 clock cycles to address a column of memory, where a CAS2 rated memory module can accomplish the same task

      CMOS Checksum Bad Error

      Computer users frequently encounter CMOS Checksum Bad Error for many reasons. This error may be frustrating, but the good part is that it can be solved easily. There are very few reasons for the CMOS Checksum Bad Error, hence they can be handled effectively. The Error Explained A checksum is computed as an error detecting
