Throughout the world, from Shanghai to New York, we cannot enter a café or walk down the street without seeing someone chatting, texting, or surfing the Internet by their mobile phones, laptops or tablet PCs. Information Technology (IT) has appear everywhere and is changing every aspect of how we live and work. 

  Modern advances in our capability to communicate and process information in digital form are reshaping the economies and societies of many countries around the world.

  IT is a key factor in the process of globalization. Developments in the early 1990s in computer hardware, software, and telecommunications greatly increased people’s ability to access information and economic potential. While advancements in Internet-based tools over the past five to ten years, such as social networking websites, twitter, are changing the way people use and share information for personal and commercial purposes. These developments have accelerated efficiency gains in all sectors of the economy. IT drives the innovative use of resources to promote new products and ideas across nations and cultures, regardless of geographic location. Creating efficient and effective channels to exchange information, IT has been the catalyst for global integration.

  Information technology is used in nearly every aspect of life in contemporary industrial societies. The spread of IT and its applications has been amazingly rapid. Just 30 years ago, for example, the use of desktop personal computers was still limited to a fairly small number of technologically advanced people. The overwhelming majority of people still type documents with typewriters, which allowed no management of text and offered no storage. Twenty years ago, big and heavy mobile telephones were carried only by a small number of users in just a few U.S. cities. Now, there were cell phone in almost all over the world. In some developing countries, mobile phones are used by more people than the fixed line telephone network.

  Just fifteen years ago, only scientists were using (or had even heard about) the Internet, the World Wide Web was not up and running, and the browsers that help users navigate the Web had not even been invented yet. Today, of course, the Internet and the Web have transformed commerce, creating entirely new ways for retailers and their customers to make transactions, for businesses to manage the flow of production inputs and market products, and for job seekers and job recruiters to find one another. According to ITU World Report 2013, the total amount of users reached more than 2.7 billion (39 percent of the world’s population) by 2013.

  The news industry was dramatically transformed by the emergence of numerous Internet-enabled news-gathering and dissemination outlets. Websites, blogs, instant messaging systems, e-mail, social networking sites and other Internet-based communication systems have made it much easier for people with common interests to to connect, exchange information, and collaborate with each other. Education at all levels is continually transforming thanks to innovations in communication, education, and presentation software. Websites now serve as a primary source of information and analysis for the masses.

  Globalization accelerates the change of technology. Every day it seems that a new technological innovation is being created. The pace of change occurs so rapidly many people are always playing catch up, trying to purchase or update their new devices.  Technology is now the forefront of the modern world creating new jobs, innovations, and networking sites to allow individuals to connect globally.
