Examples of programs that you can use to defragment your computer include the following: Spooling is a process in which data is temporarily held to be used and executed by a device, program or the system. <>/Font<>>>>> A mainframe computer uses multiple computer terminals that are connected to the main computer. e.Which application do you use to find out how the computer is using its resources? For example, in printer spooling, the documents/ files that are sent to the printer are first stored in the memory or printer spooler. While these cores are contained in one physical unit, they are actually individual processors. An example of this is exporting a file from Microsoft Word (.doc) to a PDF reader (.pdf). 5. When this happens, it is known as fragmentation. Finally, we will look at some of the factors that may decrease a computers performance, as well as some potential solutions.
