An SMPS (Switched-Mode Power Supply) is a device that provides power to motherboards in small electronic devices such as laptops and mobile devices. It is often used in situations that require small or light weight components, where an ATX power supply would not be suitable. An SMPS is also capable of a much more efficient transfer of energy, as it is capable of managing voltage and current levels by switching between on and off at fast speeds, rather than simply dissipating extra voltage like ATX power supplies do.   Applications Read More

Domains and Forests A domain in Active Directory consists of a set of computers and resources that all share a common directory database. Domains contain all the objects that exist in the network and can store a multitude of objects. Each domain contains information on the objects that they contain. A domain is also a security boundary. Domain trees are created by adding child domains to a parent domain. Domains that are grouped into a domain tree have a hierarchical naming structure and also share a contiguous namespace. A forest Read More

Some materials have the ability to produce electricity when subjected to mechanical stress. This is called the piezoelectric effect. This stress can be caused by hitting or twisting the material just enough to deform its crystal lattice without fracturing it. The effect also works in the opposite way, with the material deforming slightly when a small electric current is applied. Piezoelectricity was discovered more than one hundred years ago and has many applications today. It is used in electronic clocks, gas ovens, inkjet printers, and many other appliances. It is Read More

A colorimeter is a computer software that is able to determine the linear scales of perceived colors as they are collected from a camera. Colorimeters can be found on computers and mobile devices alike, but always require filtered photo detectors. Colorimeters can be used to provide accuracy readings for digital imaging applications in order to improve quality and pixel definition. Colorimeters can be used to analyze any color, but are almost always used to analyze red, green, blue, and yellow.   How Colorimeters Work Colorimeters are used in conjunction with Read More

Digital converter boxes receive the digital over-the-air ATSC (signals broadcast by local stations. These boxes have their channel tuners and can include closed-captioning decoding, V-chip 2.0 ratings, program guides, and their own remote control. Like a VCR, the converter box uses your television for the display and sound. Digital converter boxes have a coaxial input which connects to an ATSC-compatible antenna. For output, the converter box will also have a coaxial connector. Many televisions already have coaxial connectors and will require only a cable to connect to the television. Older Read More

Cydoor, also known as Cydoor Desktop Media, is an intrusive ad-supported software that may be downloaded in conjunction with freeware or even shareware. Cydoor has been flagged by numerous sources as a potentially malicious spyware program that does not properly seek the user’s permission to access his/her browser or connect to Cydoor servers in order to download additional advertisements and upload user-related statistics.

One of the biggest reasons that many small businesses fail within the first year is that many entrepreneurs jump into their new small business without any kind of financial management at all. In business, an entrepreneur cannot afford to rely solely on their own mental checkbook to manage their money. That does not, however, mean that an entrepreneur needs to hire an expensive accountant to keep track of his/her finances. With the declining economy at hand, many entrepreneurs are turning to automated accounting software to manage their expenses, losses, and Read More

Persons may want to trace an email address for several reasons. For example, a private investigator may need to trace an email address to find out where a person is located or who their service provider is. A server administrator may wish to trace an email address in order to block abusive users or report them to the authorities. Likewise, an individual may want to trace an email address to learn more about a person who has emailed them or prevent harassment.   How to Trace an Email Address One Read More

The Domain is the core unit of logical structure in Active Directory. All objects that share a common directory database and trust relationship with other domain and security policies are known as Domains. Each domain stores information only about the objects that belong to that domain. All security polices and settings, such as administrative rights, security policies, and Access Control Lists (ACLs), do not cross from one domain to another. Thus, a domain administrator has full rights to set policies only within domain they belong to. Domains provide administrative boundaries Read More
