Object-Oriented programming is a common paradigm which is used in software development. The object is an instance of a class which are created by classes. The objects … [Read more...]

Difference Between Tree and Graph

Tree and graph come under the category of non-linear data structure where tree offers a very useful way of representing a relationship between the nodes in a hierarchical structure and graph follows a network model. Tree and graph are differentiated by the fact that a tree structure must be connected and can never have loops while in the graph there are no such restrictions. A non-linear data structure consists of a collection of the elements that are distributed on a plane which means there … [Read more...]

Difference Between Virus, Worm and Trojan Horse

Software that is intentionally inserted into a system for causing damage is known as malicious software. Primarily this software is classified into two categories; in the former category, the software requires a host for its execution.
