Although many users like this new feature, it requires additional memory and can slow down computer operations if Read More

Widescreen usually refers to the aspect ratio of an image. In general terms, most images are considered to be in widescreen format when they have an aspect ratio larger than 4:3. When talking about widescreen, generally, most people are referring to the aspect ratio or shape of their TV set, monitor or digital image. One of the best ways to understand widescreen is to compare it with the most common type of aspect ration, 4:3 which is the aspect ratio or shape of a standard TV set. A standard TV Read More

VDSL2 is an acronym which stands for Very High Bit Rate Digital Subscriber Line Generation 2. This is based on of the original Very High Bit Rate Digital Subscriber Line (VDSL) but runs on a different frequency (30 MHz) over 7 different bands to produce extremely high bandwidth capabilities. The service for VDSL2 is available in many different parts of the world and can be accessed through the copper wire phone lines that are already in place. This makes it extremely easy to get a fast connection which is available Read More

Decision engines refer to software that can be programmed to make decisions based on a number of indentifiable factors. They have been around since at least 1965 when the IBM 360 and other, more powerful computer systems made it possible and practical to develop large-scale Management Information Systems which processed data (usually from accounting and transaction systems) and provided managers with periodic, structured reports that were useful for planning and decision-making. By the late 1960s, mathematical modeling of decision support systems (DSS) or management decision systems became practical. In 1971, Read More

The Lsass.exe System Error is a problem that may affect a computer system running Windows XP.

Most people characterize an entertainment system as both audio and video components that can play a variety of media. While many people might think of a home theater system as an entertainment system, you don't necessarily need all home theater components to produce quality entertainment. Audio Entertainment System An entertainment system might be defined by some as components that can reproduce audio media such as a receiver, CD player and speakers. You can purchase these audio components separately or purchase them as an integrated audio system. Many boom boxes or Read More

A thermostat is a device that allows users to input a specific temperature into an air conditioner. Thermostats are often included in virtually every type of air conditioner including home air conditioning units, industrial air conditioners, and automotive air conditioners. Thermostats can also be used in cooling or heating units where an extreme temperature must be maintained at all times. Thermostats are relatively simple in design and are generally highly user-friendly. Mercury Switch A mercury switch consists of a glass vial of mercury connected to three separate wires and is Read More

IVR software enables companies to build custom Interactive Voice Response (IVR) systems, which can be used to provide automated self-service to inbound callers. IVR enables callers to interact more intuitively with automated phone systems, while at the same time providing significant cost reductions over human operators. IVR Call Flows A sample IVR call flow might sound like this: IVR: Hello, and thank you for calling the NRA. Would you like to Join the NRA, Contribute to the NRA, or Locate your Election Volunteer Coordinator? Caller: Election Volunteer Coordinator IVR: Thank Read More

VSWR (Voltage Standing Wave Ratio) is a metric commonly used with antenna systems for ham or shortwave radio communication. VSWR is normally defined as a ratio with a 1:1 VSWR, indicating that there is an exact or perfect match between all antenna system elements. The VSWR can also be expressed by comparing Vmax with Vmin in a ratio. Why does VSWR Exist? In order to obtain maximum power from a load, the load and generator impedance must match. If there is any mismatch or difference, then maximum power transfer does Read More
