How is weight used in linear layout?

Why do we use linear layout?
LinearLayout also supports assigning a weight to individual children with the android:layout_weight attribute. This attribute assigns an “importance” value to a view in terms of how much space it should occupy on the screen. A larger weight value allows it to expand to fill any remaining space in the parent view.
