What Is Forward Engineering? Forward engineering is a method of creating or making an application with the help of a given requirements from a client or consumer. With forward engineering, the program/application is developed from scratch and all approaches and planning is needed to be done before actual development gets started. This type of engineering … Read more
What Is NP Problem? An NP problem, short for Non-deterministic Polynomial time problem, is a class of decision problems in theoretical computer science. The class NP contains problems for which a proposed solution can be verified in polynomial time, meaning that given a solution, there exists a polynomial-time algorithm to check whether the solution is … Read more
What Is Near-Field Communication (NFC)? Near Field Communication (NFC) is a short-range wireless connectivity standard that uses magnetic field induction to enable communication between devices when they’re touched together or brought within a few centimeters of each other. Jointly developed by Philips and Sony, the standard specifies a way for devices to establish a peer-to-peer … Read more
What is Testing? Software testing is the process of evaluating and verifying that a software product or application does what it is supposed to do. In other words, testing is executing a system in order to identify any gaps, errors, or missing requirements in contrary to the actual requirements. The process of software testing aims … Read more
What is a Shallow Copy? A shallow copy of an object is a copy whose properties share the same references (point to the same underlying values) as those of the source object from which the copy was made. In shallow copy, an object is created by simply copying the data of all variables of the original object. This … Read more

What is a Supercomputer? A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The term is commonly applied to the fastest high-performance systems available at any given time. Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computations. Performance of a supercomputer is … Read more
What Is a File? Files are storage units for data. They can take many forms including text documents, audio tracks, movie clips and computer programs. Files can be edited and transferred through the Internet on that particular computer system. Different types of computer files are designed for different purposes. A file may be designed to store an Image, a … Read more
What is a Finite Automata? Finite Automata(FA) is the simplest machine to recognize patterns. The finite automata or finite state machine is an abstract machine that has five elements or tuples. It has a set of states and rules for moving from one state to another but it depends upon the applied input symbol. Basically, … Read more
