![]() RAID 1 - Mirroring and duplexing: This level is also known as disk mirroring and is considered the simplest way to implement fault tolerance.RAID 0 - Non-redundant striping: This level is used to increase the performance of the server.Nowadays, RAID is available in various schemes or RAID level as given below: It also increases the storage capacity of the system and its main purpose is to achieve data redundancy to reduce data loss. It is used to improve the overall performance and reliability of data storage. It simply balances data protection, system performance, storage space, etc. RAID (Redundant Arrays of Independent Disks) is a method used to store data on Multiple hard disks therefore it is considered as data storage virtualization technology that combines multiple hard disks. What is RAID structure in OS? What are the different levels of RAID configuration? Some of the important functions of OS are given below:Ĥ. It acts as an intermediary among users of computer and computer hardware. An OS is responsible for managing, handling, and coordinating overall activities and sharing of computer resources. The first OS was introduced in the early 1950s known as GMOs. Operating System (OS) is basically a software program that manages and handles all resources of a computer such as hardware and software. What do you mean by an operating system? What are its basic functions? What is a deadlock in OS? What are the necessary conditions for a deadlock? What are various sections of the process? What is difference between process and thread? What is difference between Kernel and OS? Write difference between micro kernel and monolithic kernel? What is Kernel and write its main functions? What do you mean by Semaphore in OS? Why is it used? ![]() What do you mean by cascading termination? What is the difference between multitasking and multiprocessing OS? What do you mean by asymmetric clustering? What is the main objective of multiprogramming? What is the difference between paging and segmentation? What is a Scheduling Algorithm? Name different types of scheduling algorithms. What is a process? What are the different states of a process? What is different between main memory and secondary memory. What is IPC? What are the different IPC mechanisms? ![]() What do you mean by process synchronization? What are the different kinds of operations that are possible on semaphore? What are the benefits of a multiprocessor system? What's the main purpose of an OS? What are the different types of OS?
