The structures of files vary from operating system to operating system. In this unit, we will discuss the fundamentals of file structures with the generic file organisations.
A file may be described as a collection of records. Though, a text file doesn't conform to this definition at the first glance, it is also a set of records and records are words in the file.
Let a file consisting of information regarding students. We may name such a file as Student file. The typical records of such file are illustrated in Figure

A file should always be stored in such a way that the fundamental operations on it can be performed easily. In other terms, queries must be able to be executed without much hassle. We target, in this unit, on the ways of storing the files on external storage devices. Selection of a specific way of storing the file on the device based on factors such as retrieval records, the way the queries can be put onto the file, the total number of keys in each of record etc.
After learning this unit, you must be able to
For splaying, three trees are maintained, the central, left & right sub trees. At first, the central subtree is the complete tree and left and right subtrees are empty. The target
How divide and conquer technique can be applied to binary trees? As the binary tree definition itself separates a binary tree into two smaller structures of the similar type,
The total of time needed by an algorithm to run to its completion is termed as time complexity. The asymptotic running time of an algorithm is given in terms of functions. Th
A spanning tree of any graph is only a subgraph that keeps all the vertices and is a tree (having no cycle). A graph might have many spanning trees. Figure: A Graph
Merging 4 sorted files having 50, 10, 25 and 15 records will take time O (100)
1) The set of the algorithms whose order is O (1) would run in the identical time. True/False 2) Determine the complexity of the following program into big O notation:
Write an algorithm for searching a key from a sorted list using binary search technique 1. if (low > high) 2. return (-1) 3. mid = (low +high)/2; 4 .if ( X
