Difference between Time-Sharing and Distributed Operating SystemIn this article, you will learn the difference between time-sharing and distributed operating systems. But before discussing the differences, you must know about time-sharing and distributed operating systems with their advantages and disadvantages. What is Time Sharing Operating System?A time-shared operating system enables numerous users to share computers at the same time. Each action or order reduces the size of the shared system, using only a little amount of CPU time for each user. As the system often switches from one user to another, every user has the impression that the entire system is dedicated to their use, despite numerous users sharing the system. A time-sharing OS uses CPU scheduling and multi-programming to give each user a small part of a shared machine at the same time. In memory, each user has at least one different program. When a program is loaded into memory and executed, it runs for a brief time, either before or after input/output is completed. It is usually in the range of 10 to 100 ms. This short amount of time during which the user has the CPU's attention is referred to as a time slice, time slot, and quantum. It is more complex than multiprogramming OS. Multiple jobs must be held in memory at the same time in both cases. Hence the system must have memory management and security. The jobs may have to swap in and out of disc from the main memory to ensure a good response time, which now functions as a backup store for the main memory. A common method of accomplishing this is virtual memory, which is a mechanism that allows you to perform a task that may not be entirely in memory. Advantages and disadvantages of Time-Sharing Operating SystemThere are various advantages and disadvantages of a time-sharing operating system. These are as follows: Advantages

What is Distributed Operating System?A distributed operating system is a concept in which distributed applications run on several linked systems via communications. A distributed OS is a network OS modification that enables more communication and integration amongst network computers. It uses a single communication channel to connect several machines. Additionally, each of these systems is equipped with a processor and memory. These CPUs may also communicate across high-speed buses or telephone lines. Individual systems communicating over a single channel are considered to be separate entities. They're also known as loosely coupled systems. It consists of several computers, nodes, and sites that are linked together through LAN/WAN lines. It enables the distribution of whole systems on a couple of center processors and supports a wide set of real-time products and users. Distributed operating systems may share computer resources and input/output files while also giving virtual machine abstraction to users. Advantages and Disadvantages of Distributed Operating SystemThere are various advantages and disadvantages of the distributed operating system. These are as follows: Advantages
