Backing up Active Directory is essential to maintaining an Active Directory database. Users can back up Active Directory with the Graphical User Interface (GUI) and command-line tools that the Windows Server 2003 family provides. Users should frequently backup the system state data on domain controllers so that they can restore the most current data. By establishing a regular backup schedule, there is a better chance of recovering data when necessary. To ensure a good backup includes at least the system state data and contents of the system disk, the user Read More

As technology has advanced over the past few decades, so has computer science. Because of this, there are now many different ways in which information can be transferred from one device to another. Servers, cables, modems, and computers all often work together in order to process and transfer data. A relatively new source of data transfer, however, has been presented and widely distributed in the form of USB. This article will define flash memory and USB while also explaining how USB works, listing the advantages of USB, and introducing USB Read More

Left handedness is a person's preference in using the left hand over the right hand which, when considering the number of people, is relatively rare. It is believed that anywhere from seven to ten percent of the adult population is left handed. The rest are predominately right handed. The fundamental problem when discussing left handedness is determining the cause. Scientists have many theories with a lot of research to back it up, but different theories all have that research. Therefore, there is no single cause of left handedness, but there Read More

If you are wondering how a color television works, you should first understand how a standard TV set works and how the brain perceives TV signals. How a TV works For the most part a TV station broadcasts a television program by converting a television program (sound and video) into a radio frequency which is then transmitted to a broad area. A TV set receives these signals and then turns these signals into sound and video by converting the radio frequency into an image. The image is created by small Read More

MILNET (Military Network) is the traditional part of ARPANET (Advanced Research Project Agency Network) that was assigned to be the backbone for the U.S. Department of Defense’s unclassified Internet email and web traffic. ARPANET referred to the entire network and later evolved to what is known as the Internet today. MILNET split away from ARPANET in 1983 so that additional security protocols could be added to MILNET, which would be used with sensitive but unclassified U.S. Military/government transmissions. ARPANET focused primarily on academic research and evolved into modern day Internet. Read More

The Remote Desktop Web Connection is a Win32-based ActiveX control (COM object) that can be used to run Remote Desktop sessions from within a browser like Internet Explorer. It is a useful alternative to the regular Remote Desktop because it can be used without installing any software on the client machine. Remote Desktop demands the user to install software on the client’s machine, which can be sometimes infeasible. Remote Desktop Web Connection is able to do this because the Remote Desktop runs within a web browser such as Internet Explorer. Read More

A proxy server is one that receives requests intended for another server and that acts on the behalf of the client (as the client proxy) to obtain the requested service. It is often used when the client and the server are incompatible for direct connection. For example, the client may be unable to meet the security authentication requirements of the server but may be required to access some services. It may also be used for screening purposes to enable the administrator to control access to undesirable sites. The proxy server Read More

Windows NT, Me, and Windows XP’s Pre Service Pack 2 users sometimes experience the “Error Performing In-page Operation” error when attempting to copy files from a disk. If a user experiences this error while trying to access a disk that  he/she inserted into the computer’s floppy, CD, or DVD drive, the error is likely related to  the disk having physical issues. Operating system paging operations are not at fault despite the working of the error. This error can also be triggered while accessing data that is stored on a local Read More

A CMOS (Complementary Metal-oxide Semiconductor) inverter is a device that produces logic functions and is the primary component of all integrated circuits. A CMOS inverter is a field-effect transistor that is composed of a metal gate that lies on top of an insulating layer of oxygen, which lies on top of a semiconductor. CMOS inverters are found in most electronic devices and are responsible for producing data within small circuits. How CMOS Inverters Work CMOS inverters work like most other types of field-effect transistors, but depend on a layer of Read More
