TCBT The Computer Based Training
The Computer-based training (TCBT) services are where a student learns by
executing special training programs on a computer relating to their occupation.
TCBT is especially effective for training people to use computer applications
because the TCBT program can be integrated with the applications so that
students can practice using the application as they learn. Historically, TCBTs
growth has been hampered by the enormous resources required: human resources to
create a TCBT program, and hardware resources needed to run it. However, the
increase in PC computing power, and especially the growing prevalence of
computers equipped with CD-ROMs, is making TCBT a more viable option for
corporations and individuals alike. Many PC applications now come with some
modest form of TCBT, often called a tutorial. Web-based training (WBT) is a type
of training that is similar to TCBT; however, it is delivered over the Internet
using a web browser. Web-based training frequently includes interactive methods,
such as bulletin boards, chat rooms, instant messaging, videoconferencing, and
discussion threads. WBT is usually a self-paced learning medium though some
systems allow for online testing and evaluation at specific times.
A videoconference (also known as a videoteleconference) is a set of interactive
telecommunication technologies which allow two or more locations to interact via
two-way video and audio transmissions simultaneously. It has also been called
visual collaboration and is a type of groupware. It differs from videophone in
that it is designed to serve a conference rather than individuals.
Video conferencing uses telecommunications of audio and video to bring people at
different sites together for a meeting. This can be as simple as a conversation
between two people in private offices (point-to-point) or involve several sites
(multi-point) with more than one person in large rooms at different sites.
Besides the audio and visual transmission of people, video conferencing can be
used to share documents, computer-displayed information, and whiteboards.
Simple analog videoconferences could be established as early as the invention of
the television. Such videoconferencing systems consisted of two closed-circuit
television systems connected via cable. During the first manned space flights,
NASA used two radiofrequency (UHF or VHF) links, one in each direction. TV
channels routinely use this kind of videoconferencing when reporting from
distant locations, for instance. Then mobile links to satellites using special
trucks became rather common.
Videoconferencing first demonstrated in 1968
Videoconferencing first demonstrated in 1968
This technique was very expensive, though, and could not be used for more
mundane applications, such as telemedicine, distance education, business
meetings, and so on, particularly in long-distance applications. Attempts at
using normal telephony networks to transmit slow-scan video, such as the first
systems developed by AT&T, failed mostly due to the poor picture quality and the
lack of efficient video compression techniques. The greater 1 MHz bandwidth and
6 Mbit/s bit rate of Picturephone in the 1970s also did not cause the service to
prosper.
It was only in the 1980s that digital telephony transmission networks became
possible, such as ISDN, assuring a minimum bit rate (usually 128 kilobits/s) for
compressed video and audio transmission. The first dedicated systems, such as
those manufactured by pioneering VTC firms, like PictureTel, started to appear
in the market as ISDN networks were expanding throughout the world. Video
teleconference systems throughout the 1990s rapidly evolved from highly
expensive proprietary equipment, software and network requirements to standards
based technology that is readily available to the general public at a reasonable
cost. Finally, in the 1990s, IP (Internet Protocol) based videoconferencing
became possible, and more efficient video compression technologies were
developed, permitting desktop, or personal computer (PC)-based
videoconferencing. In 1992 CU-SeeMe was developed at Cornell by Tim Dorcey et
al., IVS was designed at INRIA, VTC arrived to the masses and free services, web
plugins and software, such as NetMeeting, MSN Messenger, Yahoo Messenger,
SightSpeed, Skype and others brought cheap, albeit low-quality, VTC.

display a 2nd 'far site' in a multipoint call.
The core technology used in a videoteleconference (VTC) system is digital
compression of audio and video streams in real time. The hardware or software
that performs compression is called a codec (coder/decoder). Compression rates
of up to 1:500 can be achieved. The resulting digital stream of 1's and 0's is
subdivided into labelled packets, which are then transmitted through a digital
network of some kind (usually ISDN or IP). The use of audio modems in the
transmission line allow for the use of POTS, or the Plain Old Telephone System,
in some low-speed applications, such as videotelephony, because they convert the
digital pulses to/from analog waves in the audio spectrum range.
The other components required for a VTC system include:
* Video input : video camera or webcam
* Video output: computer monitor , television or projector
* Audio input: microphones
* Audio output: usually loudspeakers associated with the display device or
telephone
* Data transfer: analog or digital telephone network, LAN or Internet
There are basically two kinds of VTC systems:
1. Dedicated systems have all required components packaged into a single piece
of equipment, usually a console with a high quality remote controlled video
camera. These cameras can be controlled at a distance to pan left and right,
tilt up and down, and zoom. They became known as PTZ cameras. The console
contains all electrical interfaces, the control computer, and the software or
hardware-based codec. Omnidirectional microphones are connected to the console,
as well as a TV monitor with loudspeakers and/or a video projector. There are
several types of dedicated VTC devices:
1. Large group VTC are non-portable, large, more expensive devices used for
large rooms and auditoriums.
2. Small group VTC are non-portable or portable, smaller, less expensive devices
used for small meeting rooms.
3. Individual VTC are usually portable devices, meant for single users, have
fixed cameras, microphones and loudspeakers integrated into the console.
2. Desktop systems are add-ons (hardware boards, usually) to normal PC's,
transforming them into VTC devices. A range of different cameras and microphones
can be used with the board, which contains the necessary codec and transmission
interfaces. Most of the desktops systems work with the H.323 standard. Video
conferences carried out via dispersed PCs are also known as e-meetings.
Echo cancellation
A fundamental feature of professional VTC systems is acoustic echo cancellation
(AEC). AEC is an algorithm which is able to detect when sounds or utterences
reenter the audio input of the VTC codec, which came from the audio output of
the same system, after some time delay. If unchecked, this can lead to several
problems including 1) the remote party hearing their own voice coming back at
them (usually significantly delayed) 2) strong reverberation, rendering the
voice channel useless as it becomes hard to understand and 3) howling created by
feedback. Echo cancellation is a processor-intensive task that usually works
over a narrow range of sound delays.
Multipoint videoconferencing
Simultaneous videoconferencing among three or more remote points is possible by
means of a Multipoint Control Unit (MCU). This is a bridge that interconnects
calls from several sources (in a similar way to the audio conference call). All
parties call the MCU unit, or the MCU unit can also call the parties which are
going to participate, in sequence. There are MCU bridges for IP and ISDN-based
videoconferencing. There are MCUs which are pure software, and others which are
a combination of hardware and software. An MCU is characterised according to the
number of simultaneous calls it can handle, its ability to conduct transposing
of data rates and protocols, and features such as Continuous Presence, in which
multiple parties can be seen onscreen at once.
MCUs can be stand-alone hardware devices, or they can be embedded into dedicated
VTC units.
Some systems are capable of multipoint conferencing with no MCU, stand-alone,
embedded or otherwise. These use a standards-based H.323 technique known as
"decentralized multipoint", where each station in a multipoint call exchanges
video and audio directly with the other stations with no central "manager" or
other bottleneck. The advantages of this technique are that the video and audio
will generally be of higher quality because they don't have to be relayed
through a central point. Also, users can make ad-hoc multipoint calls without
any concern for the availability or control of an MCU. This added convenience
and quality comes at the expense of some increased network bandwidth, because
every station must transmit to every other station directly.
Issues
Some observers argue that two outstanding issues are preventing
videoconferencing from becoming a standard form of communication, despite the
ubiquity of videoconferencing-capable systems. These issues are:
1. Eye Contact: It is known that eye contact plays a large role in
conversational turn-taking, perceived attention and intent, and other aspects of
group communication. While traditional telephone conversations give no eye
contact cues, videoconferencing systems are arguably worse in that they provide
an incorrect impression that the remote interlocutor is avoiding eye contact.
This issue is being addressed through research that generates a synthetic image
with eye contact using stereo reconstruction.
2. Appearance Consciousness: A second problem with videoconferencing is that one
is literally on camera, with the video stream possibly even being recorded. The
burden of presenting an acceptable on-screen appearance is not present in
audio-only communication. Early studies by Alphonse Chapanis found that the
addition of video actually impaired communication, possibly because of the
consciousness of being on camera.
The issue of eye-contact may be solved with advancing technology, and presumably
the issue of appearance consciousness will fade as people become accustomed to
videoconferencing.
Standards
The International Telecommunications Union (ITU) (formerly: Consultative
Committee on International Telegraphy and Telephony (CCITT)) has three umbrellas
of standards for VTC.
1. ITU H.320 is known as the standard for public switched telephone networks (PSTN)
or VTC over integrated services digital networks (ISDN) basic rate interface (BRI)
or primary rate interface (PRI). H.320 is also used on dedicated networks such
as T1 and satellite-based networks;
2. ITU H.323 is known as a standard for transporting multimedia applications
over LANs. This same standard also applies to older implementations of voice
over IP VoIP. In recent years, the IETF's Session Initiation Protocol (SIP) has
gained considerable momentum in practice for these two services.);
3. ITU H.324 is the standard for transmission over POTS, or audio telephony
networks.
In recent years, IP based videoconferencing has emerged as a common
communications interface and standard provided by VTC manufacturers in their
traditional ISDN-based systems. Business, government and military organizations
still predominantly use H.320 and ISDN VTC. Though, due to the price point and
proliferation of the Internet, and broadband in particular, there has been a
strong spurt of growth and use of H.323, IP VTC. H.323 has the advantage that it
is accessible to anyone with a high speed Internet connection, such as DSL.
In addition, an attractive factor for IP VTC is that it is easier to set-up for
use with a live VTC call along with web conferencing for use in data
collaboration. These combined technologies enable users to have a much richer
multimedia environment for live meetings, collaboration and presentations.
Impact on the general public
High speed Internet connectivity has become more widely available at a
reasonable cost and the cost of video capture and display technology has
decreased. Consequently personal video teleconference systems based on a webcam,
personal computer system, software compression and broadband Internet
connectivity have become affordable for the general public. Also, the hardware
used for this technology has continued to improve in quality, and prices have
dropped dramatically. The availability of freeware (often as part of chat
programs) has made software based videoconferencing accessible to many.
For many years, futurists have envisioned a future where telephone conversations
will take place as actual face-to-face encounters with video as well as audio.
Sometimes it's just not possible or practical to have a face-to-face meeting
with two or more people. Sometimes a telephone conversation or conference call
is adequate. Other times, an email exchange is adequate.
Video conferencing adds another possible alternative. Consider video
conferencing when: ? a live conversation is needed; ? visual information is an
important component of the conversation; ? the parties of the conversation can't
physically come to the same location; or ? the expense or time of travel is a
consideration.
Deaf and hard of hearing individuals have a particular interest in the
development of affordable high-quality videoconferencing as a means of
communicating with each other in sign language. Unlike Video Relay Service,
which is intended to support communication between a caller using sign language
and another party using spoken language, videoconferencing can be used between
two signers.
Impact on education
Videoconferencing provides students with the opportunity to learn by
participating in a 2-way communication platform. Furthermore, teachers and
lecturers from all over the world can be brought to classes in remote or
otherwise isolated places. Students from diverse communities and backgrounds can
come together to learn about one another. Students are able to explore,
communicate, analyze and share information and ideas with one another. Through
video conferencing students can visit another part of the world to speak with
others, visit a zoo, a museum and so on, to learn. These "virtual field trips"
(see history of virtual learning environments) can bring opportunities to
children, especially those in geographically isolated or the economically
disadvantaged. Small schools can use this technology to pool resources and teach
courses (such as foreign languages) which otherwise couldn't be offered.
Here are a few examples of how video conferencing can benefit people around
campus:
* faculty member keeps in touch with class while gone for a week at a conference
* guest lecturer brought into a class from another institution
* researcher collaborates with colleagues at other institutions on a regular
basis without loss of time due to travel
* faculty member participates in a thesis defense at another institution
* administrators on tight schedules collaborate on a budget preparation from
different parts of campus
* faculty committee auditions a scholarship candidate
* researcher answers questions about a grant proposal from an agency or review
committee
* student interviews with an employer in another city
* Teleseminar
Impact on medicine and health
Videoconferencing is a very useful technology for telemedicine and telenursing
applications, such as diagnosis, consulting, transmission of medical images,
etc., in real time. Using VTC, patients may contact nurses and physicians in
emergency or routine situations, physicians and other paramedical professionals
can discuss cases across large distances. Rural areas can use this technology
for diagnostic purposes, thus saving lives and making more efficient use of
health care money.
Special peripherals such as microscopes fitted with digital cameras,
videoendoscopes, medical ultrasound imaging devices, otoscopes, etc., can be
used in conjunction with VTC equipment to transmit data about a patient.
Impact on business
Videoconferencing can enable individuals in faraway places to have meetings on
short notice. Time and money that used to be spent in traveling can be used to
have short meetings. Technology such as VOIP can be used in conjunction with
desktop videoconferencing to enable low-cost face-to-face business meetings
without leaving the desk, especially for businesses with wide-spread offices.
The technology is also used for telecommuting, in which employees work from
home.
Telepresence videoconferencing, where participants are able to see each other in
reasonable life-like sizes and little delay in video transmissions, has started
to make an impact on business meetings. Some good business cases have been built
on substitution of international travel with telepresence conferencing.
Videoconferencing is now being introduced to online networking websites, in
order to help businesses form profitable relationships quickly and efficiently
without leaving their place of work.
Computer Based Learning, sometimes abbreviated CBL, refers to the use of
computers as a key component of the educational environment. While this can
refer to the use of computers in a classroom, the term more broadly refers to a
structured environment in which computers are used for teaching purposes. The
concept is generally seen as being distinct from the use of computers in ways
where learning is at least a peripheral element of the experience (e.g. computer
games and web browsing).
Electronic learning or eLearning is a general term used to refer to
computer-enhanced learning. It is used interchangeably in so many contexts that
it is critical to be clear what one means when one speaks of 'eLearning'. In
many respects, it is commonly associated with the field of advanced learning
technology (ALT), which deals with both the technologies and associated
methodologies in learning using networked and/or multimedia technologies.
The worldwide e-learning industry is estimated to be worth over 38 billion euros
according to conservative estimates, although in the European Union only about
20% of e-learning products are produced within the common market. Developments
in internet and multimedia technologies are the basic enabler of e-learning,
with content, technologies and services being identified as the three key
sectors of the e-learning industry.
Growth of e-learning
By 2005, more than 4 million students were participating in on-line learning at
institutions of higher education in the United States. Many higher education,
for-profit institutions, now offer on-line classes. By contrast, only about half
of private, non-profit schools offer them. The Sloan report, based on a poll of
academic leaders, says that students generally appear to be at least as
satisfied with their on-line classes as they are with traditional ones. Private
Institutions may become more involved with on-line presentations as the cost of
instituting such a system decreases. Properly trained staff must also be hired
to work with students on-line. These staff members must be able to not only
understand the content area, but also be highly trained in the use of the
computer and Internet. Online education is increasing.
Technology
Many technologies can be, and are, used in eLearning, including:
* screencasts
* ePortfolios
* electronic performance support system
* PDA's
* MP3 Players with multimedia capabilities
* web-based teaching materials
* hypermedia in general
* multimedia CD-ROMs
* web sites and web 2.0 communities
* discussion boards
* collaborative software
* e-mail
* blogs
* wiki
* text chat
* computer aided assessment
* educational animation
* simulations
* games
* learning management software
* electronic voting systems
* virtual classrooms
* podcasts
Most eLearning situations use combination of the above techniques.
An example of this is moodle which use: discussion board threading, wiki and
real time textual chat. However, moodle is referred to a CMS, this is because
course material if often video, mp3, text documents, scanned images or links to
other web sites.
Along with the terms learning technology and Educational Technology, the term is
generally used to refer to the use of technology in learning in a much broader
sense than the computer-based training or Computer Aided Instruction of the
1980s. It is also broader than the terms On-line Learning or Online Education
which generally refer to purely web-based learning. In cases where mobile
technologies are used, the term M-learning has become more common.
E-learning is naturally suited to distance learning and flexible learning, but
can also be used in conjunction with face-to-face teaching, in which case the
term Blended learning is commonly used.

access to automated tools and content pages.
In higher education especially, the increasing tendency is to create a Virtual
Learning Environment (VLE) (which is sometimes combined with a Management
Information System (MIS) to create a Managed Learning Environment) in which all
aspects of a course are handled through a consistent user interface standard
throughout the institution. A growing number of physical universities, as well
as newer online-only colleges, have begun to offer a select set of academic
degree and certificate programs via the Internet at a wide range of levels and
in a wide range of disciplines. While some programs require students to attend
some campus classes or orientations, many are delivered completely online. In
addition, several universities offer online student support services, such as
online advising and registration, e-counselling, online textbook purchase,
student governments and student newspapers.
e-Learning can also refer to educational web sites such as those offering
learning scenarios, worksheets and interactive exercises for children. The term
is also used extensively in the business sector where it generally refers to
cost-effective online training.
Services
E-learning services have evolved since computers were first used in education.
There is a trend to move toward blended learning services, where computer-based
activities are integrated with practical or classroom-based situations.
Goals of e-learning
E-Learning lessons are generally designed to guide students through information
or to help students perform in specific tasks. Information based e-Learning
content communicates information to the student. Examples include content that
distributes the history or facts related to a service, company, or product. In
information-based content, there is no specific skill to be learned. In
performance-based content, the lessons build off of a procedural skill in which
the student is expected to increase proficiency.
Computer-based learning
Computer Based Learning, sometimes abbreviated CBL, refers to the use of
computers as a key component of the educational environment. While this can
refer to the use of computers in a classroom, the term more broadly refers to a
structured environment in which computers are used for teaching purposes. The
concept is generally seen as being distinct from the use of computers in ways
where learning is at least a peripheral element of the experience (e.g. computer
games and web browsing).

Computer-based training (CBT) services are where a student learns by executing
special training programs on a computer relating to their occupation. CBT is
especially effective for training people to use computer applications because
the CBT program can be integrated with the applications so that students can
practice using the application as they learn. Historically, CBTs growth has been

Web-based training frequently includes interactive methods, such as bulletin
boards, chat rooms, instant messaging, videoconferencing, and discussion
threads. WBT is usually a self-paced learning medium though some systems allow
for online testing and evaluation at specific times.
Pedagogical elements
Pedagogical elements are an attempt to define structures or units of educational
material. For example, this could be a lesson, an assignment, a multiple choice
question, a quiz, a discussion group or a case study. These units should be
format independent, so although it may be implemented in any of the following
methods, pedagogical structures would not include a textbook, a web page, a
video conference or an iPod video.
When beginning to create eLearning content, the pedagogical approaches need to
be evaluated. Simple pedagogical approaches make it easy to create content, but
lack flexibility, richness and downstream functionality. On the other hand,
complex pedagogical approaches can be difficult to set up and slow to develop,
though they have the potential to provide more engaging learning experiences for
students. Somewhere between these extremes is an ideal pedagogy that allows a
particular educator to effectively create educational materials while
simultaneously providing the most engaging educational experiences for students.
Pedagogical approaches or perspectives
It is possible to use various pedagogical approaches for eLearning which
includes:
* instructional design - the traditional pedagogy of instruction which is
curriculum focused, and is developed by a centralized educating group or a
single teacher.
* social-constructivist - this pedagogy is particularly well afforded by the use
of discussion forums, blogs, wiki and on-line collaborative activities. It is a
collaborative approach that opens educational content creation to a wider group
including the students themselves.
* Laurillard's Conversational Model is also particularly relevant to eLearning,
and Gilly Salmon's Five-Stage Model is a pedagogical approach to the use of
discussion boards .
* Cognitive perspective focuses on the cognitive processes involved in learning
as well as how the brain works.
* Emotional perspective focuses on the emotional aspects of learning, like
motivation, engagement, fun, etc.
* Behavioural perspective focuses on the skills and behavioural outcomes of the
learning process. Role-playing and application to on-the-job settings.
* Contextual perspective focuses on the environmental and social aspects which
can stimulate learning. Interaction with other people, collaborative discovery
and the importance of peer support as well as pressure.
Reusability, standards and learning objects
Much effort has been put into the technical reuse of electronically-based
teaching materials and in particular creating or re-using Learning Objects.
These are self contained units that are properly tagged with keywords, or other
metadata, and often stored in an XML file format. Creating a course requires
putting together a sequence of learning objects. There are both proprietary and
open, non-commercial and commercial, peer-reviewed repositories of learning
objects such as the Merlot repository.
A common standard format for e-learning content is SCORM whilst other
specifications allow for the transporting of "learning objects" (Schools
Interoperability Framework) or categorizing meta-data (LOM).
These standards themselves are early in the maturity process the oldest being 8
years old. They are also relatively vertical specific: SIF is primarily pK-12,
LOM is primarily Corp, Military and Higher Ed, and SCORM is primarily Military
and Corp with some Higher Ed. PESC- the Post-Secondary Education Standards
Council- is also making headway in developing standards and learning objects for
the Higher Ed space, while SIF is beginning to seriously turn towards
Instructional and Curriculum learning objects.
In the US pK12 space there are a host of content standards that are critical as
well- the NCES data standards are a prime example. Each state government's
content standards and achievement benchmarks are critical metadata for linking
e-learning objects in that space.
Communication technologies used in e-learning
Communication technologies are generally categorized as asynchronous or
synchronous. Asynchronous activities use technologies such as blogs, wikis, and
discussion boards. The idea here is that participants may engage in the exchange
of ideas or information without the dependency of other participants involvement
at the same time. Electronic mail (Email) is also asynchronous in that mail can
be sent or received without having both the participants’ involvement at the
same time.
Synchronous activities involve the exchange of ideas and information with one or
more participants during the same period of time. A face to face discussion is
an example of synchronous communications. Synchronous activities occur with all
participants joining in at once, as with an online chat session or a virtual
classroom or meeting.
Virtual classrooms and meetings can often use a mix of communication
technologies.
E-Learning 2.0
The term eLearning 2.0 has been used to refer to the user of social software
such as blogs and wikis.
Parts of this article may be confusing or unclear.
Please help clarify the article. Suggestions may be on the talk page. (February
2007)
In many models, the writing community and the communication channels relate with
the E-learning and the M-learning communities. Both the communities provide a
general overview of the basic learning models and the activities required for
the participants to join the learning sessions across the virtual classroom or
even across standard classrooms enabled by technology. Many activities,
essential for the learners in these environments, require frequent chat sessions
in the form of virtual classrooms and/or blog meetings.
The various blogs that are being used for providing writing approaches are
gaining popularity.
Computer-aided assessment and learning design
Computer-aided Assessment (also but less commonly referred to as E-assessment),
ranging from automated multiple-choice tests to more sophisticated systems is
becoming increasingly common. With some systems, feedback can be geared towards
a student's specific mistakes or the computer can navigate the student through a
series of questions adapting to what the student appears to have learned or not
learned. Most software for this is still very primitive however.
The term learning design has sometimes come to refer to the type of activity
enabled by software such as the open-source system LAMS which supports sequences
of activities that can be both adaptive and collaborative. The IMS Learning
Design specification is intended as a standard format for learning designs, and
IMS LD Level A is supported in LAMS V2.

RuneScape is set in a medieval fantasy world, similar to "Guild Wars" or
"EverQuest", where players control character representations of themselves. As
with most massive multiplayer online roleplaying games (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 character's skills.

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....

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.
