How to Clear Your Browser Cache and Cookies
Why you should consider deleting these little tidbits of digital info
In computer terms, cookies don’t come in flavors, and you can’t spend cache (pronounced cash), but they’re both things you want to get rid of on a regular basis.
Whenever you open a program or a webpage, little bits of information go into a section of your computer’s memory—this is called cache. The basic purpose of cache memory is to store frequently used program instructions so they can be quickly accessed to make using programs and browsing the internet easier and faster.
Cookies are also saved on your hard drive, which represent the settings selected by you. For example, if you select the “remember me” option on a website login, the cookie will store your login information on your computer so you don’t have to fill it out every time you visit the website. Any time a website asks you to fill in a form or select preferences, chances are, you are creating a cookie.
So why is it sometimes a problem to keep the cache and cookies around?
The most important reason is privacy. Cache and cookies can give hackers access to personal information, such as the passwords and credit card information you entered in an online shopping cart. The second issue is memory; saving these bits of information takes up space on your hard drive. Finally, if cache isn’t cleared, it could cause problems calling up websites.
Developers change and update websites over time. When a site is updated, the files saved in the cache might conflict with what’s actually coded into the current website.
The drawback to clearing this information is that your saved usernames and passwords will also be deleted so you will have to re-enter them the next time you visit that website. However, this minor inconvenience is outweighed by keeping your personal information secure.
