In a singly (one-way) linear linked list, each node is divided into two parts. The first part contains the information of the element. The second part called the linked field or next pointer field contains the address of the next node in the list. A head pointer is used to hold the address of the first element in the list. Also, the last element of the linked list has a NULL value in the next pointer field to mark the end of the list. Declaration of a Linear Linked List Read More

Fiber optic lines, which can be as thin as a piece of human hair, are made of strands of glass that are optically pure. They are used to transmit light signals, and have the ability to carry these signals over long distances. How is Light Transmitted Through Fiber Optics? The process by which light is transmitted through fiber optics can best be described through the use of an analogy. If you want to shine a light through a tunnel, you can do so by pointing a flashlight down the tunnel Read More

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
