# Difference between serial search and binary search

Dictionary analogy is better for me Basically, each time we search for the target and miss, we can eliminate half of the remaining items. Searching starts with the first difference between serial search and binary search and then moves to each item in turn until either a match is found or the search reaches the end of the data set with no match found. Binary Search finds the middle element of the array. Please read the appropriate sections in your course material which, has hopefully, been selected and prepared by your instructor s.

But for binary search the values must be in sorted order. If not you will be jumping all over the oceans without finding the value: This gives us a nice O log n time complexity. Computers are now very powerful and so checking potentially every element in the list for difference between serial search and binary search match may not be an issue with lists of moderate length. This results in O n performance on a given list.

In complexity terms this is an O n search - the time taken to search the list gets bigger at the same difference between serial search and binary search as the list does. Searching starts with the first item and then moves to each item in turn until either a match is found or the search reaches the end of the data set with no match found. Also you can see visualized information about Linear and Binary Search here: A binary search comes with the prerequisite that the data must be sorted.

This results in O n performance on a given list. Checks that middle value is greater or lower than the search value. So if an item is inserted or deleted, the computer will need to re-order the list before that algorithm can be applied.

But for binary search the values must be in sorted order. So always do the sorting. Repeat this until the desired item is found.

So if an item is inserted or deleted, the computer will need to re-order the list before that algorithm can be applied. Ask yourself, should this person be to the left or to the right. The binary search would ask: May 4 '09 at In this we check the middle element.

Revision resources include exam question practice and coursework guides. A linear search works by looking at each element in a list of data until it either difference between serial search and binary search the target or reaches the end. A binary search, on the other hand, is when you open the book usually in the middlelook at the name on top of the page, and decide if the name you're looking for is bigger or smaller than the one you're looking for. The overhead of doing this may actually mean that serial searching performs better than other methods.

Ask yourself, should this person be to the left or to the right. This gives us a nice O log n time complexity. Its easy but work needed is in proportion to the amount of data to be searched.
