What is a utility software? Can it be used by any kind of users (people)? Also, explain 'data synchronization' utility.

Utility software is system software designed to help analyze, configure, optimize or maintain a computer. It usually focuses on how the computer infrastructure (including the computer hardware, operating system, application software and data storage) operates. Due to the focus on how the computer infrastructure operates, utility software is often technical and targeted at people with an advanced level of computer knowledge. Data synchronization utilities establish consistency among data from a source to target data storage and vice versa. There are branches of this type of utility: File synchronization utilities: They maintain consistency between two sources and may be used to create redundancy or backup copies. These are also used to help users carry their digital music, photos and video in their mobile devices. Revision control utilities: These are intended to deal with situations where more than one user attempts to simultaneously modify the same file.
