Unit 2: D1

Task 5

Clean up tools for removal of cookies: cookies from being on certain websites are used by companies to know information about you e.g. the sites that you regularly visit. When this happens all the data is stored up on the computer and can slow the whole system down. The cleanup tools allow the user to remove these cookies to help to speed up the computer system, so the system can be used more effectively.

Drive formatting: this helps the performance of the computer system and in terms of storage data as the hard drive can be formatted; enabling all data to be erased and a new copy of the operating system can be re-installed back onto the computer, so it runs faster and smoother.

Security virus protection: if your computer has a virus, the operating system will slow down. Installing protection enables the viruses to be removed so the system works at a faster speed. Although time can be wasted when viruses are on your computer, files may be deleted and then need to be replaced. So if the viruses are removed a lot of time is saved. This improves the performance of the computer system, meaning the information on the computer is safe, so you do not have to worry about losing any work or having any of your personal information stolen e.g. passwords to bank accounts etc.
