Advantages of binary search over sequencial search?
Linear search takes linear time with a worst case of O(n) for n items, and an average of O(n/2). Binary search takes logarithmic time, with a worst and average case of O(n log n). Binary search is therefore faster on average.
Which one is faster A binary search of an ordered set of elements in an array or a sequential search of the elements?
There is no such thing as an insertion search. There is only insertion sort, which is a method of sorting an unsorted list. Sequential search (or linear search) is only used with unsorted lists. If the list is sorted, a logarithmic search is quicker, by starting from the middle. If the items is not here, it must be in the lower half or the upper half, thus one half of the list can be discarded. You then repeat by starting in the middle of the remaining half. Thus for a list of 15 items, you end up with a list of 7, then 3, then 1, then 0. Thus it takes 5 comparisons to determine that an item does not exist. With linear search it would take 15 comparisons to determine that an item does not exist. Thus logarithmic search is quicker, but only works with sorted lists.
Random access and sequential access file in vb 6.0?
To access a particular data item in a sequential file, you need to read in all items in the file prior to the item of interest. This works acceptably well for small data files of unstructured data, but for large, structured files, this process is time-consuming and wasteful. Sometimes, we need to access data in non-sequential ways. Files which allow non-sequential access are random access files.
What is binary search and linear search in data structure?
A Binary Search is a technique for quickly locating an item in a sequential list.A Sequential Search is a procedure for searching a table that consists of starting at some table position (usually the beginning) and comparing the file-record key in hand with each table-record key, one at a time, until either a match is found or all sequential positions have been searched.
How you can improve search efficiency of sequential search for a sorted file?
When sequentially searching n items, the best-case is O(1) and the worst-case is O(n). But when the items are sorted, binary search will improve efficiency. The best case is still O(1), but worst case drops to O(log n) where log n is the binary logarithm of n. Binary search starts with the middle element of the set. If the set is empty, the item we're looking for does not exist but if the middle element is the item we are looking for then we are done. If not, a simple comparison will tell us in which half of the set to discard (including the middle element). We repeat the process with the remaining half. If there are no elements remaining, the item does not exist.
What is searching. With the help of illustrative examples describe sequential search and binary search Develop the algorithms for the same.?
Searching of algorithm is finding an item with specified properties among a collection of items. The items may be stored individually as records in a database; or may be elements of a search space defined by a mathematical formula or procedure, such as the roots of an equation with integer variables; or a combination of the two, such as the Hamiltonian circuits of a graph A Binary Search is a technique for quickly locating an item in a sequential list. A Sequential Search is a procedure for searching a table that consists of starting at some table position (usually the beginning) and comparing the file-record key in hand with each table-record key, one at a time, until either a match is found or all sequential positions have been searched.

How many checks on average would it take to search a list of 1000000000 items using a linear search?
It would take a long time
Items that are not suitable for a binary search?
The only items suitable for a binary search are those which are in a sorted order.

I need free items?
use your favorite search engine, for example Google.com and type in the search "free items". I'm sure you can get something from that
What is the use of search engine?
to search for information and other items that are of importance or not so
Write a short note on linear search?
Linear search, also known as sequential search, is a process that checks every element in the list sequentially until the desired element is found. The computational complexity for linear search is O(n), making it generally much less efficient than binary search (O(log n)). But when list items can be arranged in order from greatest to least and the probabilities appear as geometric distribution (f (x)=(1-p) x-1p, x=1,2),then linear search can have the potential to be notably faster than binary search.
