Flowchart and pseudocode are the ways to represent the control flow through the statements of the program, algorithm, process, etc. The significant difference between the flowchart and pseudocode is how they represent the control flow. The flowchart is a graphical representation of an algorithm. However, the pseudocode is the text-based representation of the algorithm. Well, we can use these concepts together to design software, or we can even use them independently. In this section, we … [Read more...]

Servlet and JSP (Java Server Page) are the programs that run on java-enabled web servers or application servers. Though both of them extend the functionalities of the web server or application server but, they do differ in many ways. Servlets are simple java programs that developers design to handle the request from the web browser and generate a dynamic response for the same. On the other hand, JSP is a successor of the servlet, as it is also used to generate a dynamic response for the request … [Read more...]

Actual and formal parameters are two different forms of parameters that we use while declaring, defining and invoking a function. The actual parameter is the one that we pass to a function when we invoke it. On the other hand, a formal parameter is one that we pass to a function when we declare and define it. Actual parameters are the genuine values that a function has to work on. However, the formal parameters are just variables defined to accept the real values on which the function will … [Read more...]

The LISP and Prolog are the programming languages intended to serve for the different purpose, where LISP is a functional programming language while Prolog is a completely logic programming language. LISP was considered as the model of computation which is founded on the theory of the recursive functions. Prolog, on the other hand, contains a group of specifications in formal logic which uses first-order predicate calculus. LISP is faster than Prolog as it easily interpreted by … [Read more...]

The black box and white box testing are the type of testing methods, which can be differentiated according to the approaches used for testing. Black box testing does not contain any information about the internal structure of the software but the functional specifications of the software are used to design the test cases. Conversely, the white box testing needs entire information about the internal structure of the software to construct the test cases. Software testing is the method of … [Read more...]

Interfaces used to enable several distinct classes to share a probable group of properties and methods. The Interface is useful for abstracting a class where it specifies the operation performed by the class but does not reveal the background working or how it is going to do it. While inheritance assists the creation of specialized subclasses by base class and this is helpful in reusing the code. More generally inheritance is used to extend the class functionality. However, both are the … [Read more...]

Prim's and Kruskal's algorithms are designed for finding the minimum spanning tree of a graph. These algorithms use a different approach to solve the same problem. Prim's algorithm works by selecting the root vertex in the beginning and then spanning from vertex to vertex adjacently, while in Kruskal's algorithm the lowest cost edges which do not form any cycle are selected for generating the MST. These algorithms are designed for the undirected graph. The Minimum Spanning Tree (MST) is a … [Read more...]

To solve the optimization problem in computing the two methods namely greedy and dynamic programming are used. The solutions produced by the greedy algorithms are more effective than the dynamic programming solutions. The primary difference between the greedy method and dynamic programming is that greedy method just generates only one decision sequence. As against, dynamic programming can produce many decision sequences. Content: Greedy Method Vs Dynamic Programming Comparison … [Read more...]

The Virtualization enables one computer to carry out the job of multiple computers, with the help of sharing resources of single hardware across several environs. The full virtualization and paravirtualization are categorized under CPU virtualization. These are mainly distinguished by the fact that in full virtualization the unmodified OS is not awared about the virtualization and it uses binary translation to trap the OS calls at the run time. Conversely, in paravirtualization, the hypercalls … [Read more...]

Aggregation is a particular type of Association, not a standalone concept. The terms are used for setting up a relationship between the objects and classes. The aggregation and association can be distinguished by the fact that if the relationship between the two objects is part-whole type, it is an aggregation. In contrast, if the linked objects can be considered as independent, then this is known as an association. These concepts are very useful in class modelling, where an intuitive graphic … [Read more...]
