The internet as we know it today uses a huge variety of different processes to carry out its functions. Many examples can be pointed to, but the two that dictate information flow on the internet are downloading and uploading. Downloading is the taking of, or copying of a file from a server onto your computer. Uploading is basically the reverse of this, and together these two processes make it possible to have a flow of information.

We all use these mechanisms to share data, often without realizing it. The act of simply visiting a web page will initiate a download of some kind, possibly multiple downloads of temporary files. In order to understand the processes the internet uses you have to first recognize how it is built. Things become more clear when you look at it as a structure (or network) of connected computers and servers that are able to transfer data with each other from anywhere in the world.

Due to these processes of interconnected servers and systems, it is always important to have strong security and a set of rules in place for the transferring of information. Hackers and crackers abuse the fact that the internet operates in the way that it does, and it pays to be careful about security when it relates to your online activity.
