Optimizing Proxy Server Performance In order to optimize server performance for whatsoever reason, you need to start by monitoring the server. In most cases, before server monitoring commences, it is common practice to establish baseline performance metrics for the specific server. Baseline performance metrics are established by measuring the performance of a particular server under various conditions, at different times of the day, week, and month, and when the hardware and software configuration changes. Based on the baseline metrics which you define for the server, you would need to optimize Read More

A bucky ball is a fullerene molecule which is any molecule that is made up entirely of carbon. Specifically, a bucky ball is a spherical fullerene while the cylindrical fullerene is called a carbon nanotube. They were discovered in 1985 and are referred to, chemically, as C60. When they were discovered, it expanded the number of carbon allotropes–the way the atoms are aligned–which had, before this, been diamond, graphite and soot/charcoal. Now fullerene molecules adds another allotrope to the mix. Because scientists are still working hard on determining what bucky Read More

An impact printer is one that depends on a forceful impact to transfer ink to a material such as a t-shirt, sign, or sheet of paper. Impact printers differ from digital, inkjet, and inkless printers as it actually collides with the material itself. Typewriters, industrial printers, and daisy wheel printers are all forms of impact printers. Impact printers have many uses although they have generally been considered obsolete since the introduction of more modern printing techniques. How Impact Printers Work In a typical impact printer, a mesh, cloth, or ridged Read More

DigiCipher II (DCII) is a Motorola proprietary digital video distribution system. DigiCipher II provides compression, encryption, and authorization. DigiCipher II compression is based upon MPEG-2. DigiCipher II is utilized for some TVRO transmissions. A Motorola 4DTV satellite receiver is required to decode DigiCipher II TVRO channels. DigiCipher II utilizes AC3 audio encoding.

XML Tutorials XML stands for eXtensible Markup Language and it’s designed to store and transport data. Like HTML, it is a markup language that’ designed to carry data, and not to display data. XML is not a replacement for HTML. Basically. it’s just created to structure, and transport information. Just sort of like an information that is wrapped in tags. Below are some of our XML tutorials to know more about it. XML Document Tutorial A tutorial that shows how to create XML Document In an XML file there can Read More

A wireless mesh network relies on radio signals to allow several devices within a coverage area to communicate with each other. Wireless mesh networks are often used in conjunction with other networks in order to give users reliability and stability. This is because wireless mesh networks communicate with each other through any device within the coverage area and automatically restore communication if one device stops working. Wireless mesh networks include everything that other networks do (router/gateway, clients, etc.) but do not necessarily need to connect to the Internet. How Wireless Read More

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

A MagicJack is a VoIP (Voice over Internet Protocol) device that allows users to connect their home telephones to their computer in order to make free calls. A number of influential magazines such as the L.A. Times, CNBC, PC Magazine, and the New York Times strongly recommend MagicJack.

How MagicJack Works A MagicJack has a USB attachment on one 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
