An FQDN, or Fully-Qualified Domain Name, is a domain name that specifies the exact location of a webpage. An example of an FQDN, would be “http://www.byteguide.com/”, in which “com” is used to specify the root domain that ByteGuide is hosted on, “www” specifies the hostname, and “http” specifies the transfer protocol. While an FTP or SSH client may be able to recognize the address “byteguide.com”, it may not, depending on the client’s settings. To ensure that a client is able to locate the ByteGuide server, it is wise to always Read More

A quantum is the most basic physical unit that is involved in any type of interaction. For example, a quanta (plural) is the transfer of different energy particles such as photos and bosons when discussing matter. Because of the Latin of the word quantus meaning "how much," it can be concluded that when discussing quantum, it is because of the idea that there is a quantifying of the energy. In other words, a quantum allows for a physical property to be quantified. Because it can be quantified, it means that Read More

Use disk quotas to manage storage growth in distributed environments. Disk quotas allow you to allocate available disk space to users based on the files and folders that they own. Windows 2003 disk quotas track and control disk space usage on a per-user, per-partition basis. Characteristics of Windows 2003 Server Disk Quotas Disk usage is based on file and folder ownership. When a user copies or saves a new file to an NTFS partition or takes ownership of a file on an NTFS partition, windows 2003 changes the disk space Read More

Google Plus, which Google provides, is a social networking service that differs from other social networking services as it provides users with a variety of features that other social networking websites do not. These features include Myspace and Facebook. Google Plus includes a feature known as “Circles” that allows users to place friends in specific categories and only send status updates to friends in each specific category. This allows users to send messages to appropriate contacts such as friends, family members, and co-workers, without allowing those contacts to view inappropriate Read More

A loop antenna is one that is designed to receive radio signals more efficiently than other antennas. Loop antennas are considered more efficient than others because they are mobile, work with a wide range of frequencies, and use less electricity. A loop antenna’s performance is entirely dependent on its construction and placement, although other factors may also play a role. Loop antennas locate areas with ideal signal strength, and improve signal quality and communication. How Loop Antennas Work A loop antenna is made of a loop of copper or another Read More

Audio control software refers to software applications that can play multi-digital formats, giving the user control over the control module’s sound, features, and appearance. Some of the more popular audio control software programs available today are Nullsoft Winamp, SnackAmp, Ecasound, Supercollider, and Microsoft’s Windows Media Player. Nullsoft Winamp Winamp is an audio control software that plays a variety of formats including MP3, MP1, MP2, AAC, WAV, WMA, MIDI, MOD, OGG, Vorbis, FLAC, etc. In addition, Nullsoft’s Winamp plays AVI files including MPEG and NSV (Nullsoft Streaming Video). Besides being able Read More

The earliest forms of access control systems assigned privileges to users. These early access control systems allowed the system administrator to enable defined privileges for users like Bob and Doug. The addition of user groups improved that situation. The system administrator could now assign privileges to groups such as Sales or Accounting and add users into those groups. Role Based Access Control (RBAC) is the next evolutionary step in access control. Role Based Access Control (RBAC) enables privileges to be assigned to arbitrary roles. Those roles can then be assigned Read More

Organic Light-Emitting Diodes (OLED) are considered by many people as the next step in display technology, with the potential of replacing current plasma or LCD large-screen televisions with ultra-slim, ultra-light screens that can be folded when not in use. They are currently being used in small screen displays such as computer monitors, digital cameras and car TV screens. The next stage of development is to create commercially-viable, large TV screens. LED and OLED In order to understand OLED, one needs to start with the light-emitting diodes or LED. Simply put, Read More

A VGA adapter is a component that has a male side and a female side that allows for graphics to be presented on a screen. VGA which stands for video graphics array is a method in which information is presented on a screen. Currently, it is the "lowest common denominator" when it comes to the type of graphics that a computer will have. The base is VGA and then any components added supercede the VGA. History of VGA In 1987, IBM unveiled the display hardware known as VGA. It was Read More

A Capacitor Bank is a group of several capacitors of the same rating that are connected in series or parallel with each other to store electrical energy . The resulting bank is then used to counteract or correct a power factor lag or phase shift in an alternative current (AC) power supply. They can also be used in a direct current (DC) power supply to increase the ripple current capacity of the power supply or to increase the overall amount of stored energy. What Does a Capacitor Bank Work? Capacitor banks Read More
