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
(1) Sort a list of distinct numbers in ascending order, using the following divide- and-conquer strategy (Quicksort): divide the list of numbers into two lists: one that contains a
Q. Explain the insertion sort with a proper algorithm. What is the complication of insertion sort in the worst case?
(i) Consider a system using flooding with hop counter. Suppose that the hop counter is originally set to the "diameter" (number of hops in the longest path without traversing any
Ask question #MWhich of the following is not a characteristic of good algorithm? inimum 100 words accepted#
In internal sorting, all of the data to be sorted is obtainable in the high speed main memory of the computer. We will learn the methods of internal sorting which are following:
Djikstra's algorithm (named after it is discovered by Dutch computer scientist E.W. Dijkstra) resolves the problem of finding the shortest path through a point in a graph (the sour
Q. What is the need of using asymptotic notation in the study of algorithm? Describe the commonly used asymptotic notations and also give their significance.
