Clear PC Cache

If you have a broadband (very fast) connection, the time you save using a cache might be pretty small. The idea of a Web cache goes back to the days not so long ago when most of us used dial-up access to the Internet. At 56 Kbps (dial-up/modem speed) or slower, shaving off some time to get a few graphics files was significant. Dial-up is still around today, and in these cases it's still a factor, but to most of us, the time-saving benefits of a browser cache are negligible.
In this article, we'll show you how to clear your cache so your PC will run faster and safer, while showing you the latest versions of the pages you are viewing.

Cache contents can interfere with Web viewing
Consider the case where a page has been updated since you last loaded it. Sites that update frequently, such as news sites, usually but not always contain special code that forces the browser to check for updated pages. If the browser doesn't check first, the outdated version in the cache will load instead of the fresh content.
Cached material can also be a security risk
Many Web sites are designed to prevent any sensitive information you enter, such as banking data or passwords, from being stored in your cache. Unfortunately, you have no way of knowing if this is the case, which can leave your computer vulnerable to a hacker's attack. Usernames and other sensitive information are also often used in the contents of the address bar, which provides another route into the browser cache.
It's easy to manually clear your browser cache
