Iastor.sys (iaStor.sys) or Intel Matrix Storage Manager is a storage file for accessing the drivers, hardware, and software of RAID devices. RAID (Redundant Array of Independent Disks) is a type of hard drive arrangement in which the same data is copied onto multiple hard drives in order to backup files. Iastor.sys runs on Windows XP, Windows Vista, and Windows 7 and can be found in the Drivers subfolder of the primary hard drive’s System32 folder.   How Iastor.sys Works Iastor.sys manages and controls RAID devices in order to maintain file Read More

SRAM, or Static Random Access Memory, is a type of memory device that stores accessed files and commands in a semi-permanent chip that only empties itself of stored data when it is no longer being powered, i.e. when the computer is unplugged or turned off. SRAM differs from DRAM, or Dynamic Random Access Memory, which stores data even when the computer is unplugged, but must be refreshed regularly to empty old data. While SRAM is highly efficient and very convenient for quick access, it is mostly only used to store Read More

Radiometric dating is a process of identifying the age of a material based on known half-lives of decaying radioactive materials found in both organic and inorganic objects. Radiometric dating is often used to determine the age of rocks, bones, and ancient artifacts. In fact, radiometric dating can be used to determine the age of the Earth, (5.54 billion years old) other planets, and celestial objects. Radiometric dating is often referred to as “radioactive dating” and “carbon dating,” though many different types of isotopes can be used to identify an object’s Read More

The Boltzmann Constant (Boltzmann’s Constant) is a fundamental physics constant that plays a pivotal role in almost every single statistical formulation in both quantum and classical physics. It is named after Austrian physicist, Ludwig Boltzmann (1844 – 1906), who made significant contributions to the foundation and development of a particular branch of theoretical physics known as statistical mechanics. Definition The Boltzmann Constant, symbolized by k or kB, is the relationship between absolute temperature and kinetic energy in each molecule of an ideal gas. It is equal to the ratio of Read More

The Sarbanes-Oxley Act was signed into law on July 30, 2002 by President Bush, and was approved by the House by a vote of 423-3 and by the Senate 99-0. Sarbanes-Oxley is considered the most significant change to federal securities laws in the United States since the New Deal. Officially titled the Public Company Accounting Reform and Investor Protection Act of 2002, and commonly called SOX and Sarbox, it was named after sponsors Senator Paul Sarbanes (D-MD) and Representative Michael G. Oxley (R-OH) and came as result of a series Read More

Microsoft Publisher is a Microsoft Office product that allows users to create brochures, flyers, calendars, newsletters, and more. Microsoft Publisher saves time and money by allowing the user to design professional products without graphical design experience. In addition to inserting text, uploading pictures, and sizing content, Microsoft Publisher includes templates that allow the user to automatically generate professional documents that are already laid out with sample text and images.   What is Microsoft Word? Microsoft Word is a Microsoft Office product that allows users to create tables, charts, and documents Read More

The term image rollover refers to the technique of changing an image display on a web page when the end-user mouses over a picture or image embedded on a web page. When you program a web page to contain a rollover image, two pictures are commonly used for the effect. One of the images is displayed when the web page is loaded in the user's web browser, and the second image is displayed when the mouse is positioned over the image. The JavaScript method “onMouseOver” is invoked when the mouse Read More

DMADV is one of two major methodologies of the Six Sigma system. The Six Sigma system is a way to improve processes in work and manufacturing and its main goal is to eliminate defects. The Six Sigma methodology has been widely used by many Fortune 500 corporations with amazing results and can be used in small groups to achieve goals or on a corporate level affecting tens of thousands of workers. The short definition of the Six Sigma system is a set of practices that improve efficiency and remove defects. Read More

The RG-59 cable is a type of coaxial cable that is used to generate low-power video connections. The cable works on two conductors that are based on a single common axis. It is also used for RF signal connections. The RG-59 cable conducts video and radio frequencies at an impedance of around 75 ohms. The RG-59 cable is used for generating short-distance communication. The cable can be used at baseband video frequencies, which is measured from the lowest count of zero and continues to the highest signal frequency. Baseband refers Read More
