ARPANET – The Advanced Research Projects Agency Network

So what is Arpanet, why was it developed and what impact does it have on our everyday lives, both personal and in business

Arpanet is a global system of interconnected computer networks that use a standard Internet protocol called TCP/IP, this was finally developed in the 1960s as a working model for the United States Department of Defense and funded by DARPA – the Advanced Research Projects Agency.

ARPANET-1977

The Defense Advanced Research Projects Agency (DARPA) is an agency of the United States Department of Defense responsible for the development of new technologies for use by the military.

This network was developed to share information between agencies across the United States, it was not that long in development when people started to see the commercial aspects of this system, hence the birth of what we use in our everyday lives, a system which we call the Internet, also known as the interwebs.

The internet has had a huge impact in our lives in relation to and how we go about our day-to-day business, shopping and our social communications with one another.

In 2012; as a nation we developed a huge global network infrastructure, consisting of the largest array of systems you could ever imagine, this includes mobiles networks, wired networks, and satellite system networks, all operating to provide us with a way to communicate effectively between large and short distances.

According to the US National Aeronautics and Space Administration (NASA), there are more than 24,500 space objects orbiting Earth. What impact does this really have in the way our planets function?

The largest obstacle to overcome when developing an infrastructure of this size is the security that goes behind such a system. Unfortunately we don’t all live in a harmonious society, people like to deface systems, and show they can manipulate information, it’s for these reasons alone we have t o protect our technology.

There was a time if one required information passed from one place to the next, this could take hours or days, even weeks for this information to be received at the other end. With this new array ‘which has been developed’, means we now have a system to share information almost instantaneous.

Arpanet is the route of how the internet started, and going back to our roots really gives you a better understanding of how networks run. I am fascinated with networks and have been since 1998.
