 The various types of operating systems are as follows - (i) Desktop system  (ii) Multiprocessor system (iii) Clustered system (iv) Handheld system  (v) Real-time system  (vi) Multitasking  (vii) Multiprogramming  (viii) Distributed system (i) Desktop system :- Personal computers PCs introduced in the 1970s. During their first decade, the CPUs in PCs lacked the features needed to protect an operating system from use programs. Therefore, PC operating systems were neither multiuser nor multitasking. However, PC operating systems have changed with time; instead of maximizing CPU and peripheral utilization, the systems opt for maximizing user convenience and responsiveness. These systems include PCs running Microsoft Windows and the Apple Macintosh. The MS-DOS operating system from Microsoft has been superseded by multiple flavors of Microsoft Windows, and IBM has upgraded MS-DOS to the OS/2 multitasking system. The Apple Macintosh operating system has been ported to more advanced hardwar
