• Binary Search requires the data to be sorted before searching.
• It repeatedly divides the data into two halves to find the target value.
• This makes it much faster than Linear Search on large datasets.
• If the data is not sorted, Binary Search cannot work correctly.
• It follows the divide-and-conquer technique.
