The dawn of the net The dawn of the net video is a video which explains how email and the internet works. In th is video , the w orkings of accessing the internet is described, the devices which the information uses in the form of packaged data, and how this came to be. This video explains in detail the process of sending and receiving email s, how the emails are routed, the way the internet is used, and the security of encryption whether using the internet or not. When someone enter s a web address on a web browser, this address is to be considered as a package in which all the information is contained . P ress ing the enter button , the pack age d data travels to the local area network , or " LAN ", where the pack ag ed data is sent through to the router or intelligent switch. A router is a device which transfers data from one network to another. Then the data is sent to the n etwork in terface. From the network interface , the pack ag ed data is then sent to the proxy which serves the purpose of sending the data to the internet . This data package looks for a URL and transmitted the respective server that is the destination . Once there, data then comes upon a firewall which performs the main purpose of blocking unsecured data let ting through the desired data allowing it to reach the designated port. A nother router or switch receives the packaged data and moves it over to the band width , which performs the purpose of transferring data from one place to another . Finally , the pack ag ed data continues out to the internet or world wide web. Once it travels and reaches its destination, the data package is re - opened and the reverse process ensues. This requires a response that is sent back to the original location from where the data package was sent. The info rmation in the se packages contain information the sender was emailing to a recipient. The response is then verified after reaching security protocols, unencrypted and the email can be opened and read by the recipient. This process is used each time an email is sent and received by anyone and done over and over again .
