The Internet represents a fundamental revolution in the way the global community thinks, lives, shops, gathers information and conducts business. Since the telecommunication industry provides the infrastructure for the Internet, the two are inextricably linked. In fact, the public switched telephone network (PSTN) connects tens of millions of computers on the Internet, providing most of the transport over which the Internet protocol (IP) and related application services such as the World Wide Web are carried. In addition, the PSTN provides dial-up access to the Internet for millions of users.
The explosive growth of the Internet, and other IP-based networks, and with it the ever increasing demand for higher bandwidth/capacity, has network operators and manufacturers alike reconsidering their services, network structures, products, etc. Information technology and the use of IP-based networks and applications (e.g. e-commerce) have become critical factors in the development of telecommunication networks.
Data traffic is growing at more than ten times the rate of voice traffic and it is estimated that in the near future data will account for 80 per cent of all traffic carried by telecommunication networks. Therefore, with this rapid change, the past concept of telephone networks that also carry data will be replaced by the concept of data networks that also carry voice. In this regard, seamless interworking between IP-based networks and telecommunication networks and interoperability of their respective applications/services is essential to meet the burgeoning business requirements placed on modern communications networks.
Another important trend in telecommunication networks is the emergence of mobile networks and a significant increase in the number of customers subscribing to them. The work on the third generation mobile networks performed by ITU under the name of IMT-2000 has, as its main features, an increased data speed of 384 kbit/s up to 2 Mbit/s, a global roaming capability and the virtual home environment (enabling users to move seamlessly between fixed and mobile networks). These features will provide an additional infrastructure for the IP-based network services with fast, ubiquitous access through the global roaming capability.
Interoperability of networks and of applications is becoming an increasingly important aspect. The interaction of IP-based networks and telecommunication networks for the purpose of gaining access to the Internet, or other IP-network applications, and the need for the interoperability of IP-based services and telecommunication services means providing real time Internet or other
IP-based multimedia services with the speed, capacity, ease of use, reliability and integrity of the public telephone networks in use around the world. These are aspects of telecommunication network standardization in which ITU-T has an excellent track record.
Not only are we facing major changes in the telecommunication network, but also these changes are developing at ever shorter time intervals, with reduced development intervals and corresponding shorter life-cycles for services and products. Standards bodies must be able to change their focus and work direction to produce necessary standards at much shorter intervals.
In short, business directions are changing across the telecommunication industry. Consequently, standards organizations, forums and consortia are facing new challenges in terms of work direction and focus. We are also seeing the emergence of new bodies to address related areas.
The ultimate value of IP and telecommunication network interactions is the building of an integrated network through which people will have increased opportunities to interconnect and exchange ideas. It is a major challenge for ITU-T to meet and it is necessary, if the vision is to become reality, for ITU-T to leverage its knowledge, experience and competence in developing global standards for communications networks.
This variable is part of a study made by the International Telecommunication Union on the Internet Technology.
While the development of the Internet in developed countries has been widely documented, its diffusion in developing nations has generally not been well researched. The ITU is carrying out a series of case studies on the diffusion of the Internet in countries at different stages of development. The aim of the project will be to seek to understand the factors, which accelerate or retard the development of the Internet in different environments and, through comparative analysis, to advise policy makers and regulatory agencies on appropriate courses of action. A particular focus will be on the spread of the Internet in different sectors of the economy such as health, education and commerce as well as government.

The data is only aggregated if at least 75 % of the observations are available (i.e. % of population
or % of GDP or % of countries) on an annual basis.
The value "-9999" corresponds to "No Data".
Several values are calculated by extrapolations and interpolations; they are exclusively used for
the regional/subregional and global aggregations.

Personal computers are self-contained computers designed to be used by a single individual.
The estimates of personal computers are derived from an annual questionnaire, supplemented by
other sources. In many countries mainframe computers are used extensively, and thousands of
users can be connected to a single mainframe computer; thus the number of personal computers
understates the total use of computers.
