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...]

List and Tuple in Python are the class of data structure. The prior difference between them is that a list is dynamic, whereas tuple has static characteristics. There are the composite data types which can be used as an array of data in which elements exist in some specific intrinsic ordering, which helps in retrieval of the data. These lists and tuples can hold multiple values, which simplifies the program writing and manages large amounts of data. The lists and tuples are a sequence … [Read more...]

The PHP and JavaScript are programming languages intended for the different purposes where the PHP is mostly used for the backend purpose. On the contrary, JavaScript is used for frontend. In other words, PHP is a server-side scripting language whereas JavaScript is considered as a client-side scripting language. The features provided by PHP are more but the JavaScript is said to be more efficient and fast. PHP provides a wide of variety of functions as compared to JavaScript. Content: PHP … [Read more...]

In PHP there are four types of loops in general, while, do while, for and foreach. In this article, we are going to examine the differences between for and foreach, where the prior difference between them is that for loop uses iterator variable while foreach works only on interator array. Looping in a programming language play a crucial role in any programming construct. The primary function of a loop is to execute the same block of code several times, repeatedly until a certain condition is … [Read more...]

With advances in various disciplines of science and engineering the requirement of the more advanced computational models for solving a problem that need large computational and storage environments. Procedural and nonprocedural languages are the computations models for specifying most programming today. The major difference between these computational models is that the procedural language is command-driven whereas non-procedural language is function oriented. Furthermore, procedural … [Read more...]

The major difference between types of parsing techniques top-down and bottom-up parsing is that the top-down parsing follows method to construct a parse tree for an input string which begins at the root and grow towards the leaves. As against, in bottom-up parsing, a reverse method where the parsing starts from the leaves and directed towards the leaves. Before understanding the types of parsing, we must know what is parsing and why it's done. Parsing is the technique of examining a text … [Read more...]

High-level language and low-level language are the types of programming languages. The prior difference between high level and low-level language is that the high-level language is easily interpreted by programmers but not machines whereas low-level language can be easily understood by machines but not by humans. The low-level language contains machine language and assembly language. Content: High-Level language and Low-Level language Comparison Chart Definition Key … [Read more...]

An algorithm is a sequence of steps which is utilized in order to solve a computational problem whereas pseudocode is nothing but a more simple form of an algorithm which involves some part of natural language to enhance the understandability of the high-level programming constructs or for making it more human-friendly. Computer programming contains an enormous part, of generating unambiguous, sequence-wise procedures for the computer to follow in order to produce particular results. … [Read more...]
