How do i go online without having it visible in history on computer

Well the shortest explanation I can give is for you to download Google Chrome, and click the wrench in the upper right corner. In the menu that pops up, click New Incognito Window. When you're in the Incognito mode, not a single kilobyte of information will be stored on your computer what so ever (unless you download something).No history will be kept or anything.
