Local area network scheme
A local area network (LAN) is a computer network covering a small geographic area, like a home, office, or group of buildings. The defining characteristics of LANs, in contrast to Wide Area Networks (WANs), include their much higher data transfer rates, smaller geographic range, and lack of a need for leased telecommunication lines.

Ethernet over unshielded twisted pair cabling, and Wi-Fi are the two most common technologies currently, but ARCNET, Token Ring and many others have been used in the past.
History
In the days before personal computers, a site might have just one central computer, with users accessing this via computer terminals over simple low-speed cabling. Networks such as IBM's SNA (Systems Network Architecture) were aimed at linking terminals or other mainframes at remote sites over leased lines—hence these were wide area networks.

The first LANs were created in the late 1970s and used to create high-speed links between several large central computers at one site. Of many competing systems created at this time, Ethernet and ARCNET were the most popular.

The development and proliferation of CP/M and then DOS-based personal computers meant that a single site began to have dozens or even hundreds of computers. The initial attraction of networking these was generally to share disk space and laser printers, which were both very expensive at the time. There was much enthusiasm for the concept and for several years, from about 1983 onward, computer industry pundits would regularly declare the coming year to be “the year of the LAN”.

In reality, the concept was marred by proliferation of incompatible physical layer and network protocol implementations, and confusion over how best to share resources. Typically, each vendor would have its own type of network card, cabling, protocol, and network operating system. A solution appeared with the advent of Novell NetWare which provided even-handed support for the 40 or so competing card/cable types, and a much more sophisticated operating system than most of its competitors. Netware dominated[1] the personal computer LAN business from early after its introduction in 1983 until the mid 1990s when Microsoft introduced Windows NT Advanced Server and Windows for Workgroups.

Of the competitors to NetWare, only Banyan Vines had comparable technical strengths, but Banyan never gained a secure base. Microsoft and 3Com worked together to create a simple network operating system which formed the base of 3Com's 3+Share, Microsoft's LAN Manager and IBM's LAN Server. None of these were particularly successful.

In this same timeframe, Unix computer workstations from vendors such as Sun Microsystems, Hewlett-Packard, Silicon Graphics, Intergraph, NeXT and Apollo were using TCP/IP based networking. Although this market segment is now much reduced, the technologies developed in this area continue to be influential on the Internet and in both Linux and Apple Mac OS X networking—and the TCP/IP protocol has now almost completely replaced IPX, AppleTalk, NBF and other protocols used by the early PC LANs.
Technical aspects
Although switched Ethernet is now the most common data link layer protocol and IP as a network layer protocol, many different options have been used, and some continue to be popular in niche areas. Smaller LANs generally consist of a one or more switches linked to each other - often with one connected to a router, cable modem, or DSL modem for Internet access.

Larger LANs are characterized by their use of redundant links with switches using the spanning tree protocol to prevent loops, their ability to manage differing traffic types via quality of service, and to segregate traffic via VLANing.

LANs may have connections with other LANs via leased lines, leased services, or by 'tunneling' across the Internet using VPN technologies.

Wide Area Network (WAN) is a computer network that covers a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries [1]). Or, less formally, a network that uses routers and public communications links [1]. Contrast with personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively. The largest and most well-known example of a WAN is the Internet.

WANs are used to connect LANs and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private. Others, built by Internet service providers, provide connections from an organization's LAN to the Internet. WANs are often built using leased lines. At each end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. Network protocols including TCP/IP deliver transport and addressing functions. Protocols including Packet over SONET/SDH, MPLS, ATM and Frame relay are often used by service providers to deliver the links that are used in WANs. X.25 was an important early WANSACHMO protocol, and is often considered to be the "grandfather" of Frame Relay as many of the underlying protocols and functions of X.25 are still in use today (with upgrades) by Frame Relay.

Academic research into wide area networks can be broken down into three areas: Mathematical models, network emulation and network simulation.

Performance improvements are sometimes delivered via WAFS or WAN Optimization.

RuneScape has often been one of the top massive online role playing games. It is a unique game. But, with a unique game, comes unique players. Players get bored, and then try to develop cheats....autos or bots that will help them achieve success in their beloved games of Runescape 2.

RuneScape is a virtual world which is divided into two part: Members Areas and Non-Members areas. People who pay to play (p2p), receive access to the special areas. They also have access to the free areas. The members' places are much larger, offer "better" items for the gameplay of rs2, and much, much more. The character that you create when you first start playing runescape, moves around the game on foot; either by running, or walking. Players are challenged to their utmost skills by fighting new monsters, completing difficult quests, and manipulating marketing. As Runescape 2 is an RPG (Role playing game), there is no set path a person must take to play rs. They can choose what to do, and when, whether it be training their money-making skills, or fighting another player. Players usually interact with each other by chatting through public chat, or private chat.Internet Junction For Gamers, Runescape Market and More IJFG.COM IJFG.com was a runescape 2 based site. They have now, however, taken another look....

Of course the king of all game cheating websites is trick the trik (otherwise known as RPG Cheats Site), where you can find cheat forums, mmorpg topsite, arcade games and any mmo game related topics.

The master of massive multiplayer online role-playing games (MMORPG) cheats can be found at Trik.com Trik.com; this site is one of the best today. The forum section, Trik.com forum, originally came from IJFG.com (Internet Junction For Gamers) , which was one of the best websites that discussed various gamers' issues. The full name was Internet Junction For Gamers, Runescape Market and More. This site had Jokes, Pranks, RuneScape and other cool games. RuneScape is set in a medieval fantasy world, similar to "Guild Wars" or "EverQuest," where players control character representations of themselves. As with most MMORPG, there is no overall objective or end to the game. Players explore, form alliances, perform optional tasks, and complete quests for rewards and to build characters' skills.

Trik.com continues IJFG.com's success, but Trik.com has more to offer. Trik Topsite can be found at Trik Topsite; the TopSite is a great addition if you want to find the best MMO RPG site(s) or raise your site in the rankings. Trik.com also has a viciously competitive Arcade. If you want to be the #1 Arcade on Trik, then come prove yourself at Trik.com arcade: Trik arcade.  Trik.com – Trik.com/topsite – Trik.com/forum/arcade.php

With the rising popularity of commercial MMORPG games came the desire from ardent players of these games to run their own servers beside the ones run by the game's creator. Since the original server software is not usually available, the behavior of the server has to be re-engineered. This can be done by analyzing the data stream with the original server, or by disassembling and analyzing the client which is available.

Ultima Online was one of the first large MMORPGs. Due to its openness in implementation, server emulators arose very quickly, even during the beta stage of development. The destination to which the client connects was changeable by simply editing a text file. In beta stage the client-server data stream was not encrypted yet. The term server emulator became known through Ultima Online server reimplementation such as UOX, which was the pioneer. Many forks and reimplementations followed UOX, because its source code was released under the GNU General Public License relatively early. RunUO is today the most widely used UO-server emulator. After RuneScape implemented anti-cheating measures, many gamers left and started their own private servers. The best place to discuss the private server is at Trik- The Master of Private Server.
 

Another useful site is Rune Web ruwb.com . This site is about more serious RuneScape gold trading, account exchange, gold for real life cash and many services. It includes tips on how to avoid getting lured/scammed while using the marketplace. For programming, visual basics, java, C/C++, scar and all other languages such as PHP, HTML, ASP, Delphi. There are also sections for graphics talents, plus many cool videos and fun stuff.

A defining moment in internet gaming history was when a group of gamers called (hygo 7) decided to start an ultimate game forum, which they named hygo.com. It has the best financial backing, the friendliest game community, and the highest quality of information. Currently Hygo.com has entered a new phase...Hygo.com is offering the best private server game. With thousands of members, Hygo.com is your next place to visit, as they have an amazing game with a community and economy. Hygo.com - The Online Adventure Game. is definitely one of the top sites you want to join right now!
