      How to Repair a Bad Sector

      Occasionally, one or more sectors on an otherwise good hard drive will go bad. When this happens, the data in those sectors may be lost, but the data on the rest of the disk will be unaffected and the disk is still completely usable. Those bad sectors cannot be repaired, but they can be marked

    • 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

      Dual Core

      A dual core processor is part of a category called multi-core processors. These computer processors have more than one independent processor on the chip or package. In the case of a dual core processor, the entire chip has two independent computer processors that can work together to increase total computer performance. For non-technical consumers, dual

      Athlon

      Athlon is a name for AMD’s main line of Intel-compatible CPUs. The Athlon line is designed to complete against the Intel Pentium CPUs. Athlon CPUs feature a L1 cache with 64KB of memory for data and another 64KB of memory for instructions. Athlon CPUs support MMX, 3DNow!, and SSE. Some models of Athlon CPUs also

    • What is a Hypervisor?

      What is a Hypervisor?

      A hypervisor is a virtualization technique that runs multiple operating systems on the device. While non-hypervisor virtualization techniques run multiple operating systems on domestic computers and hand-held devices, hypervisors are used exclusively on devices whose sole task is to run multiple guest operating systems for commercial or industrial purposes. Hypervisors are used in gaming technologies,

      What is a PDA?

      A PDA (Personal Digital Assistant) is a computer that fits in one’s hand. These small computers are sometimes called palmtops and are a great way to store telephone numbers and email addresses, access the Internet, make calculations, keep a digital calendar, and play games. Today’s PDA is very small, fits comfortably in a pocket, and

      How Wireless Speakers Works

      The Need for Wireless Speakers A common complaint against home audio systems has been the cables that interconnect the speakers to the audio receiver, tuner, cd player, or stereo units. As more and more channels are added to modern home audio equipment the problem of connecting the speakers to the audio sources has exacerbated. Running

    • What is a Pressure Transmitter?

      What is a Pressure Transmitter?

      A pressure transmitter or pressure sensor is a device that measures pressure in a liquid, fluid, or gas. Pressure transmitters are commonly used to measure pressure inside of industrial machinery in order to alert the user before a catastrophe occurs. They have many different uses, most of which are industrial or automotive in nature. A

      Stability Problems Caused by File Fragmentation

      File and disk fragmentation usually causes problems in large networked companies where many people simultaneously save, retrieve and delete their work on a company’s servers. In an ideal scenario, people will be ‘lining up’ to use the company’s servers, allowing data management (especially storage and retrieval) to proceed in an orderly, logical, and sequential manner.

      How to Overclock a CPU

      Overclocking is the process making a computer component run at a higher speed than that specified by the manufacturer. The components that can be overclocked include the CPU, the memory and the video cards. Although there may be many different reasons for overclocking, the most common reason is to increase hardware performance. For example the
