The Inner Workings of the Internet
When a link is clicked on a flow of information is created. The information is then sent and “packaged” by the IP. The packages are known as packets which have a limited size. It then must be decided on how to divide in the information and how to package it. Each packet will get a label that contains information. Packets that are going out across the internet get a special address for the proxy server.
The packet then gets latched onto your local area network (LAN). The LAN is used to connect everything on the network together to exchange information within the physical walls of the building. The traffic of information that goes across the LAN is uncontrolled place because there are all sorts of different packets going across the LAN.
The router is a device that essentially plucks certain packets off the highway of information and places them on a different network. The router will identify which packets go where by the address that is on each packet. As the packets leave the router they head into the corporate internet and head for the router switch. The router switch is a bit more efficient than the router and routes the packets on their way.
The packets are sent to be picked up by the proxy. The proxy works like a middle man for companies to lessen the load of their internet connection and for security reasons. The proxy opens the packets and looks for the web address(URL). If the package is acceptable the packet is then sent to the internet.
The next thing the packets go through a firewall. The firewall serves two primary purposes. The first purpose is to prevent packets from coming through that are carrying malicious things intended to hurt the company. The second thing the firewall does is prevent sensitive company information from being sent out across the internet. Once the packets get past the firewall, a router then picks them up on places them on a “road” known as bandwidth. The packet is then sent out across the internet.
The internet is a web on networks that are all connected that span the entire globe. The internet isn’t very regulated and because of that many ideas go out across the internet. The lack of regulation also increases the level of danger that is out there on the internet such as the “ping of death.”
After the packet travels across the internet and reaches its destination it will encounter another firewall which will decide if the packets can pass are not. If the packet doesn’t meet the right criteria then the packet is destroyed.
After making it past the firewall. The packets are then eventually taken up to the web server. One by one the packets are received, opened and unpacked. The information they contain is then sent to the web server application. The packet then gets recycled and is ready to get recycled and refilled with information that you have requested.
