When using a multiple-user operating system, it is important to make sure that you balance the requirements of each user so that the resources of the main computer are shared among the users. If you feel that you will need additional protection, Chapter 6 has some recommendations on which programs to buy. To prevent this problem, many CPUs now have a small, high-speed cache built into the CPU, where it can temporarily store the data it needs. This allows you to quickly load those images from your computer when you visit the page again, rather than to wait to have them load over a slow internet connection. One of the most important tasks of the operating system is to help the computer manage hundreds of processes that run at the same time. This includes checking for updates, looking for and downloading messages and emails, and making sure you are connected to an internet-enabled network. Importing and exporting can also be used to manage files and documents on your computer or smartphone. This will ensure that the document is in the correct folder and, therefore, can be found with more ease. 2.Choose a term or concept from Column B that matches the description in Column A.
