PC Software includes a wide range of programs and tools that can make your computer more effective and efficient, or even enjoyable. Examples include word processors, multimedia and music players video games graphics and design software and online tools for communication such as Skype or Google Hangouts or an even more robust email program. Microsoft products, email clients social media clients editors, PDF readers, and productivity software, such as calculator, calendar, or to-do list are also very popular.
Computer operating systems (OS) are the most widely used type of computer software. OS software typically comes with the graphical user interface (GUI) or, in the case of some OS types, a more complicated command-line interface. These GUIs are the primary interfaces with which a typical computer user interacts with their OS.
System software is usually written in a low-level programming language, which makes it easier to talk to the hardware systems. It also manages many essential functions, such as memory management and task scheduler.
A clean-up program is a godsend if your hard drive has become full of old backups or a massive installation of a program. SpaceSniffer from Uderzo Software, for instance will help you recover space by scanning your hard drive and displaying the results in an easy-to-understand grid. When you’re ready to allow the old files to be thrown out, a powerful undelete program like Recuva, from Piriform (the creators of CCleaner), can bring them back from the dead.
