A linear search has a time complexity of $O (n)$ because it checks each element in the list one by one, so the time it takes increases linearly with the size of the list. A binary search, on the other hand, has a time complexity of $O (l o g n)$ because it repeatedly divides the list in half until it finds the target value, so it is much more efficient for large lists. However, binary search requires the list to be sorted, while linear search does not.
