Operating Systems Types of Operating System Real-Time A real-time operating system is a multitasking operating system that aims at executing real-time applications. Responds to input instantly.

Operating Systems Types of Operating System Multi-user vs. Single user A multi-user operating system allows multiple users to access a computer system concurrently. Time-sharing system can be classified as multi-user systems as they enable a multiple user access to a computer through the sharing of time. Single-user operating systems, as opposed to a multi-user operating system, are usable by a single user at a time.

Operating Systems Types of Operating System Multi-tasking vs. Single-tasking When a single program is allowed to run at a time, the system is grouped under a singletasking While system in case the operating allows system execution of the multiple tasks classified as a multi-tasking at one operating time, it system. is

Operating Systems Types of Operating System Distributed A distributed operating system manages a group of independent computers and makes them appear to be a single computer. The development of networked computers that could be linked and communicate with each other, gave rise to distributed computing.

Operating Systems Types of Operating System Embedded Embedded operating systems are designed to be used in embedded computer systems. They are designedto operateon small machines like PDAs with less autonomy. They are able to operate with a limited number of resources.
