Digital divide is an economic and social inequality with regard to access to, use of, or impact of information and communication technologies (ICT). The divide within countries (such as the digital divide in the United States) may refer to inequalities between individuals, households, businesses, or geographic areas, usually at different socioeconomic levels or other demographic categories. The divide between differing countries or regions of the world is referred to as the global digital divideexamining this technological gap between developing and developed countries on an international scale.The infrastructure by which individuals, households, businesses, and communities connect to the Internet address the physical mediums that people use to connect to the Internet such as desktop computers, laptops, basic mobile phones or smart phones.  Traditionally the nature of the divide has been measured in terms of the existing numbers of subscriptions and digital devices.

However, research shows that the digital divide is more than just an access issue and cannot be alleviated merely by providing the necessary equipment. There are at least three factors at play: information accessibility, information utilization and information receptiveness. More than just accessibility, individuals need to know how to make use of the information and communication tools once they exist within a community.

Information professionals have the ability to help bridge the gap by providing reference and information services to help individuals learn and utilize the technologies to which they do have access, regardless of the economic status of the individual seeking help.Internet connectivity can be utilized at a variety of locations such as homes, offices, schools, libraries, public spaces, Internet cafe and others. There are also varying levels of connectivity in rural, suburban, and urban areas. Digital divide may exist for a number of reasons. Obtaining access to ICTs and using them actively has been linked to a number of demographic and socio-economic characteristics: among them income, education, race, gender, geographic location (urban-rural), age, skills, awareness, and political, cultural and psychological attitudes. Most commonly, a digital divide stems from poverty and the economic barriers that limit resources and prevent people from obtaining or otherwise using newer technologies.

Community Informatics (CI) provides a somewhat different approach to addressing the digital divide by focusing on issues of "use" rather than simply "access". CI is concerned with ensuring the opportunity not only for ICT access at the community level. Connecting to the Internet creates another set of means by which to achieve repeated interactions. ICTs and Internet connectivity enable repeated interactions through access to social networks, chat rooms, and gaming sites. Once an individual has access to connectivity, obtains infrastructure by which to connect, and can understand and use the information.

New applications have made it possible for anyone with a computer and an Internet connection to be a creator of content, yet the majority of user generated content available widely on the Internet, like public blogs, is created by a small portion of the Internet using population. Technologies like Facebook, YouTube, Twitter, and Blogs enable users to participate online and create content without having to understand how the technology actually works, leading to an ever increasing digital divide between those who have the skills and understanding to interact more fully with the technology.

The more frequently a person has access to the Internet and the faster the connection, the more opportunities they have to gain the technology skills and the more time they have to be creative that ICTs and connectivity provide, that individual is capable of becoming a "digital citizen.

The global digital divide also contributes to the inequality of access to goods and services available through technology. Computers and the Internet provide users with improved education, which can lead to higher wages; the people living in nations with limited access are therefore disadvantaged.Telephone is often seen as one of the most important components, because having access to a working telephone can lead to higher safety.Computer and Internet use is regarded as being very important to development and success. However, some children are not getting as much technical education as others, because lower socioeconomic areas cannot afford to provide schools with bundles of computers.

Moreover, they say that with the help of modern technology people can artificially create conditions that will allow people to live there on the constant basis. To sum up, I am sure that many amazing changes will be brought by it. Furthermore, I think that with the help of the contemporary technologies people can do many things that were even difficult to imagine a century ago. So, nowadays it is rather difficult and even impossible to imagine all changes that will happen in the next decades.Indeed given us a lot of advantages by making us richer, healthier, and freer to enjoy our lives, it has, in my opinion, not made us wiser. The 21st century has also made our earth dirtier, our people less humane, and our spiritual lives poorer. We should continue to enjoy the benefits of technological advancements because they free us to pursue our interests and goals. However, we must make a concerted effort to preserve our natural environment for future generations. Moreover, we should take the time now to make our lives more meaningful in an increasingly impersonal, computerized world.
