What is an Analog Computer? An analog computer is a type of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical or hydraulic quantities to model the problem being solved. Analog computers store data in continuous form of physical quantities and perform calculations with the help of measures. It is … Read more

What Is Nintendo Wii? The Wii was the seventh generation home video game console released by Nintendo in 2006 and an upgrade to its predecessor, GameCube. This console introduced motion controlled gaming to a wide audience of Nintendo fans and people who didn’t traditionally play video games. It’s often credited with having made video games … Read more

Abstract Class An abstract class is a class that is declared abstract — it may or may not include abstract methods. Abstract classes cannot be instantiated, but they can be subclassed. An abstract class may have static fields and static methods. When an abstract class is subclassed, the subclass usually provides implementations for all of the abstract methods in its … Read more

What Is Multicast? Multicast in computer networking is communication between a single sender and multiple receivers on a network. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with physical layer point-to-multipoint communication. In multicast, a multicast group identifies a set of recipients that are interested in a particular data stream and … Read more

What Is For Loop? A For-loop is a control flow statement for specifying iteration, which allows code to be executed repeatedly. A for-loop has two parts: a header specifying the iteration and a body which is executed once per iteration. The header often declares an explicit loop counter or loop variable, which allows the body … Read more

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
