In this blog, we will discuss two types of operating systems - Clustered Operating Systems and Handheld System Operating Systems. Clustered Operating Systems:           A clustered operating system is an operating system that is designed to manage a group of interconnected computers, called a cluster, as a single system. I…

Introduction:           A network operating system (NOS) is an operating system that manages network resources and allows multiple computers to communicate with each other over a network. In this blog, we will discuss network operating systems in detail, including their history, design, and uses. History of Network Operating Systems…

Introduction:           A distributed operating system is a type of operating system that manages a group of independent computers and makes them appear as a single system. In a distributed operating system, the individual computers communicate and coordinate their activities through a network. In this blog, we will discuss distribu…

Introduction:           A multiprocessor operating system is a type of operating system that is designed to run on multiple processors or cores. It is responsible for managing the allocation of system resources, such as CPU time, memory, and input/output (I/O) devices, among multiple processors. In this blog, we will discuss multipr…

Introduction:           A desktop operating system (OS) is the software that manages the hardware and software resources of a desktop computer. It provides a graphical user interface (GUI) that allows users to interact with their computer and run applications.   In this blog, we will take a closer look at desktop operating systems, …

Introduction:           Mainframes are large, powerful computers that have been used for critical business applications since the 1950s. They are known for their reliability, security, and scalability, and have been used in industries such as finance, healthcare, and government.  In this blog, we will take a closer look at mainframe…

Introduction:           Operating systems have been an essential part of modern computing since the earliest days of computers.
