      What is an LPAR?

      LPAR (Logical Partitioning) is a way of subdividing all of a computer’s resources, including the memory, storage, and processors, and splitting them up into smaller logical units that can each be run as a separate part of the operating system (OS). In order for LPAR to be implemented, it requires the computer to have specialized

    • CMOS Checksum Bad Error

      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

    • LCoS (Light Crystal over Silicon)

      LCoS (Light Crystal over Silicon)

      LCoS (Light Crystal over Silicon) is a technology used in display systems. LCoS shares some elements with LCD and DLP (Digital Light Processing) displays. As such, LCOS systems are not exactly new though it was only recently that commercial manufacture became viable. The best way to understand LCoS television is to understand the process. How

      How to Format an SD Card

      Secure Digital (SD) memory cards are very simple to format. There are 3 main options to format the SD cards to the format needed. To successfully format an SD card, the write protection lock on the side of the card must be in the “unlock” position. SD mini and micro SD cards must be used

    • Hard Disk Partitions

      Hard Disk Partitions

      A hard disk partition is a defined storage space on a hard drive. Most operating systems allow users to divide a hard disk into multiple partitions, in effect making one physical hard disk into several smaller logical hard disks. Reasons to Use Hard Disk Partitions A user may decide to split a hard disk into

    • 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

    • Lossy Compression

      Lossy Compression

      Lossy compression is a type of compression that removes unnecessary components of a file to reduce the file’s size. Lossy compression is often used in multimedia files, such as still images and audio files that hold a significant amount of redundant information. Lossy compression results in a reduction of quality of the file that is

      L1 Cache

      The L1 cache refers to the first tier in a computer processor’s memory cache system that increases the speed at which the processor delivers results to the user. The L1 cache sits between the processor and the computer’s RAM (Random Access Memory) and stores the user’s most accessed data in order for the processor to
