Listing 10 of 18 questions
Tick the most accurate statement referring to the use of compilers and interpreters. ✓ An interpreter creates a single executable file that runs directly on the CPU It is easier to debug compiled code rather than interpreted code With a compiler it is harder to protect intellectual property as machine code is easy to understand It is more difficult for hackers to modify compiled code Tick the most accurate statement referring to the use of disk formatting. ✓ Disk formatting increases the number of fragments in a hard disk Disk formatting never removes viruses from a hard disk Disk formatting increases the storage capacity of a blank disk Disk formatting is used to fully prepare a hard disk for initial use

Tick the statement which most accurately refers to the results of using utility software. ü Lossless compression reduces the number of bits by increasing redundant data Some information is lost in lossless compression Lossy compression reduces the number of bits by identifying unnecessary information and removing it Disk defragmentation organises the contents of the disk into the largest number of contiguous regions Tick the statement which most accurately refers to the properties of a hard disk. ü Data access is faster on a hard disk with fragmented files than on a defragmented hard disk Disk formatting prepares a data storage device for initial use The first stage of formatting is high-level formatting followed by low-level formatting Disk partitioning makes the data storage device invisible to an operating system A type of utility software enables files to be deleted. Explain how the delete utility works and how files can be recovered even after they appear to have been deleted.
