In 1994, an incredibly forward-thinking man named Rasmus Lerdorf developed a set of tools that used a parsing engine to interpret a few macros here and there. They were not extravagant: a guest book, a counter, and some other "home page" elements that were cool when the Web was in its infancy. He eventually combined these tools with a form interpretation (FI) package he had written, added some database support, and released what was known as PHP/FI.Then, in the spiri....

One of the most widely used network topologies (and the one most often used in medium to large Local Area Networks) is the bus network. A bus network uses a cable to which are attached all the network devices, either directly or through a junction box of some sort. Each device uses a transceiver to connect to the backbone. The manner of attachment depends on the type of bus network, the protocol in use, and the speed of the network. The main cable that is used to connect all t....

The File Transfer Protocol (FTP) is one protocol in the TCP/IP family used to transfer files between machines running TCP/IP (FTP-like programs are also available for some other protocols). The File Transfer Protocol enables you to transfer files back and forth and manage directories. FTP is not designed to give you access to another machine to execute programs, but it is the best utility for file manipulation. To use FTP, both ends of a connection must be running a program th....

The type of cabling used in a network is called the network medium. Today, networks use many types of cables, although only a few types are in common usage. Some of the more exotic types of cables are very expensive. The type of cabling can have an influence on the speed of the network, although for most small- to medium-sized local area networks this is not a major issue. Twisted pair cabling is one of the most commonly used network mediums because it is cheap and easy to wor....

A Nokia mobile phone works with either the GSM network or the CDMA network. You need to choose the right model to match your wireless operator.Not all Nokia smartphones work with all wireless operators everywhere in the world. Wireless operators build their networks using different technologies, and a given phone typically works with only one of the network technologies.If you got your Nokia smartphone directly from the wireless....
