Describe each of the following utility programs: (i) compressor; (ii) defragmenter. (4 marks)DICT MOD 1 July 2020

(i) Compressor: A compressor is a utility program that is used to compress files in order to save space on a computer or other storage device. Compressors use algorithms to reduce the size of a file by eliminating redundant data and reducing the resolution of images and other media. This can make it easier to store and transfer large files, and can also save space on the computer’s hard drive or other storage device.

(ii) Defragmenter: A defragmenter is a utility program that is used to optimize the performance of a computer by reorganizing the data on its hard drive. When a computer writes and deletes files, it can leave gaps of unused space on the hard drive. Over time, these gaps can cause the computer to slow down, as it takes longer to access and retrieve data from the hard drive. A defragmenter scans the hard drive and rearranges the data in a more logical and efficient manner, filling in the gaps and making it easier for the computer to access and retrieve data. This can improve the computer’s performance and speed up its operation.
