In SharePoint, a view is a way of looking at a list or library. It allows you to filter, group, and sort items in a list or library, as well as to add or remove columns from the display. You can create multiple views for a list or library and switch between them to see different subsets of data.
For example, you could create a view that shows only high-priority tasks, or a view that shows only tasks that are overdue. You can also customize the layout of the view, such as by specifying how many items to show on each page or whether to show items in a grid or a list.
