Deleting Temporary Internet Files
A cache system is storage of data that is saved to your computer every time you visit a site. When you access a site that the cache has stored data on, the site will be accessed more quickly because you cut out the middle man (the site) and load it directly from your hard drive. This will speed up browsing time, and allow some sites to even be viewed while offline using the cache! While you wouldn’t be able to interact with other users or post things, you could view the entire site while you aren’t even connected to the Internet.
Some people use these cache systems to help out with their P2P (peer-to-peer) transfers. This will store part of the data that needs to be transferred and copied, and will allow it to load much more quickly. The cache will also hold other data that will cause the Internet to be a faster place for users and allow more data to be transferred more quickly.
The cache also comes with some risks too. Anytime identifying data or browsing history is stored on your computer, you will have some sort of privacy issue. The less information you keep about yourself and your browsing habits on your computer and on the Internet, the safer and more anonymity you will enjoy. It is possible that a hacker could gain access to your data by using your IP address to hack into your computer. It is also possible to just steal your computer and get into your cache. It is one thing for your system to be physically stolen, but if a hacker could remotely access your computer and get all sorts of sensitive information and other browsing habits, it could be forever before you found out and tried to stop it, but by then the damage could be irreversible.
