In the 21st century society is more dependant on technology than its ever been, an individual's smart phone plays a significant role in how about people go about their daily lives. The smart phone has evolved from being a very linear single purpose communication device into a device which functions much like a computer which can perform various tasks at the same time.
It can be argued that the emergence of mobile devices has caused a decline in the demand for desktop PCs as the concept of having a mobile device is more appealing to the majority of people.
One of the most significant technologies of the 21st century must be the world wide web. The world wide web is a platform in which people can share knowledge and it can be argued that you find information on almost anything on the web which in the pre-digital age you would normally need to look in a library for. As most digital devices have access to the web this enables people to have access to this huge database of information as well as access to live streaming information.
Social networking sites are very significant as for some people sites such as Facebook and Twitter consume most of their time online. Social networking sites act as platform in which you can communicate with a virtual community created by the user, it can also be used as a platform in which to communicate with people the other side of the world which wouldn't of been possible otherwise.
It can be argued that we have almost become cyborgs in which our reliance on technology is so great that its believed that having access to the internet is an optimal human state as you have access to a whole host of useful information and communication tools.
