Utilities software is software designed to assist in research, configure, optimize or maintain a computer. it’s wont to support the pc infrastructure – in contrast to application software, which is aimed toward directly performing tasks that benefit ordinary users. However, utilities often form a part of the appliance systems. for instance, a batch job may run user-written code to update a database and should then include a step that runs a utility to copy the database, or employment may run a utility to compress a disk before copying files.

Those utilities may provide additional facilities to hold out tasks that are beyond the capabilities of the OS.
Many utilities which may affect the whole computing system require the user to possess elevated privileges, while others that operate only on the user’s data don’t.
Computer Utilities & Maintenance
Software maintenance in software engineering is that the modification of a software package after delivery to correct faults, enhance performance, or other attributes.
A common perception of maintenance is that it merely involves fixing defects. However, one study indicated that over 80% of maintenance effort is employed for non-corrective actions. This perception is perpetuated by users submitting problem reports that are functionality enhancements to the system. newer studies put the bug-fixing proportion closer to 21%.
