Interact with the os through the user interface the desktop, icons, and menus that let you communicate with your computer: 2. Utility programs a small program that performs many of the general housekeeping tasks for your computer, such as system maintenance and file compression. Every computer has an os (cid:272)a(cid:374)"t fu(cid:374)(cid:272)tio(cid:374) (cid:449)ithout it. Many operating systems are similar (windows, os x, linux, ios, android) tablets/cell phones/laptops have different operating systems than normal computers. Real-time operating systems (rtos) require minimal user interaction used in machinery that performs a repetitive series of specific tasks in an exact amount of time.
