Permissions refer to the rights or privileges granted to users or systems to access or modify resources. These resources can include files, folders, applications, or databases. Permissions help ensure that only authorized individuals can perform specific actions, such as reading, writing, or executing a file. This is crucial for maintaining security and protecting sensitive information. In computing, permissions are often managed through user accounts and roles. For example, in a computer operating system, a user may have different permissions compared to an administrator. Properly setting permissions helps prevent unauthorized access and ensures that users can only interact with the resources they are allowed to use.
