What Is A Multiplexer (MUX)? A multiplexer also referred to as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. In other words, it is a combination logic circuit designed to switch one of several input lines through to … Read more
Signal is any kind of physical quantity that conveys information. This could be electric current, voltage, electromagnetic waves that are used for wireless communication, sound etc. the two categories in which signal is classified are: Digital and Analog. Analog signals are measurements of continuous waveforms that vary with time whereas Digital signals are patterns generated … Read more
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
