The Domain Name System (DNS) is a structural naming classification for computers, services, or any device connected to the Internet or private network. It basically deciphers human understandable domain names into binary identifiers associated with networking components, in order to successfully locate and address the components. In simple terms, DNS deciphers computer hostnames into IP addresses, and vice versa. This helps Internet users to easily recollect web site names instead of IP addresses. The DNS handles the task of allocating domain names and associating them with IP addresses by assigning Read More

LGA-775 is a 775-contact CPU socket used by some Intel Celeron D, Pentium D, Pentium Extreme Edition, Pentium 4, and Pentium 4 Extreme Edition processors. LGA stands for “Land Grid Array”. In English, this means that the pins in an LGA socket are built into the socket — not into the CPU. This total reversal of earlier designs gives better power distribution, which enables Front Side Bus speeds up to 266MHz. Moving the fragile pins from the CPU to the motherboard also means that if you break a pin, you Read More

The FLAC (Free Lossless Audio Codec) is an open source file format designed for the storage and playback of audio content. Unfortunately, the format is not supported on a number of music playback devices. The WAV (Waveform Audio File Format) is designed by Microsoft and IBM for both audio playback in uncompressed form. A common task for end-users is to convert FLAC files to WAV format. Steps to Convert FLAC Files to WAV Using WAV MP3 Converter Step 1 – Download and install the WAV MP3 Conversion application. Step 2 Read More

802.11i is a draft IEEE standard for 802.11 wireless network security. 802.11i defines several new standards, and also relies heavily on many existing standards. New Protocols in 802.11i 802.11i introduced the RSN (Robust Secure Network) protocol for establishing secure communications. 802.11i also introduced the WRAP (Wireless Robust Authentication Protocol) and CCMP encryption protocols. WRAP and CCMP are both based upon the AES encryption algorithm. 802.11i utilizes EAP (Extensible Authentication Protocol) as the end-to-end transport for authentication methods between the wireless NIC (Network Interface Card) and the WAP (Wireless Access Point).

Water cooling is one of the newer cooling systems available for computers with high-end cards and chips. This cooling system rests on the principle that water is a much better conductor of heat because of its high thermal conductivity and high specific heat. Water cooling systems for computers works much like the cooling system in a car where heat is dissipated by passing water over the engine and transferring this to the radiator where heat is released to the air. Traditional PC Cooling Systems Computer components generate heat through the Read More

Ray tracing is a process that involves tracing the path of light rays from the perspective of the beholder. It is one method of creating 3D graphics through the use of light. By making use of the path of light, one can create images with extraordinarily life-like or realistic effects. To render an image through ray tracing, there is a need for a ray tracing program which handles the full range of calculations needed to properly ‘render’ or portray each individual pixel or square of a designated scene. This program Read More

There are many different products and services available, especially via the Internet, that allow users to detect and crack wireless computer networks. The majority of these programs are illegal, extremely complicated to use, or both. The WiFi Scanner, however, is easy to use and allows the user to detect networks that are further away while increasing signal strength for those networks. This article will explore the WiFi Scanner and define what it does. What is WiFi Scanner The WiFi Scanner, unlike other wireless network detection devices, is an external device Read More

A touchpad is a computing interface device that typically mimics the functions of a computer mouse. Instead of having an external peripheral device such as a mouse, the touchpad enables the user to interact with the device through the use of a single or multiple fingers being dragged across relative positions on a sensitive pad. Touchpads are typically found on laptop computers but are increasingly being utilized on devices such as portable mp3 players such as Apple's iPod and PDAs such as HP's iPaq series. Touchpads are generally resilient additions Read More

When DirectX was first introduced, it was marketed to people involved in the gaming industry. Those who develop all types of graphical computer software currently use it. DirectX is “backward compatible” software, allowing the user to install a newer version of DirectX and still be able to play games created for an older version of the software. As an application programming interface, DirectX increases the performance of hardware associated with audio and video animation. Nearly all of the latest video and sound computer hardware devices for PCs are manufactured to Read More
