What is a Relay? Relays are switches that open and close circuits electromechanically or electronically. Relays are the primary protection as well as switching devices in most of the control processes or equipments. All relays respond to one or more electrical quantities like voltage or current such that they open or close contacts or circuits. … Read more

What Is Kerberos Protocol? Kerberos is a computer-network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Kerberos builds on symmetric key cryptography and requires a trusted third party and optionally may use public-key cryptography during … Read more

What Is A Waterfall Model? The waterfall Model is a software development process developed by Dr. Winston Royce in 1970. In waterfall approach, the whole process of software development is divided into separate phases. The outcome of one phase acts as the input for the next phase sequentially. This means that any phase in the … Read more

What Is Spiral Model? Spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models such as incremental, waterfall or evolutionary prototyping. Each phase in spiral model begins with a design goal … Read more

What Is Integration Testing? Integration testing sometimes referred to as integration and testing (I&T) is a level of software testing whereby individual software modules are combined logically and tested as a group. The fundamental purpose of this type of testing is detecting faults in the interaction between integrated units. Usually test drivers and test stubs … Read more

Learn the difference between black box testing and white box testing. The basis of comparison include: description, types, complexity of performance, basis of test case design and nature of the process among others.   What is Black Box Testing? Black box testing also referred to as closed-box, opaque-box, eye-to-eye, behavioral or specification-based testing, is a … Read more

The basis of comparison include: Description, Key Use, Integrity, XOR Function, Plaintext Encryption, Speed, Implementation and Algorithm modes. What is a Cipher? A cipher is a method of hiding words or text with encryption by replacing original letters with other letters, numbers and symbols through either … Read more

Learn the difference between relay and circuit breaker. The basis of comparison include: description, use, power voltage input, capacity, how it works, amplification, contact breaking and arc prevention among others. What Is A Circuit Breaker? A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess … Read more

What is Closed-Die Forging? The Closed-Die Forging also referred to as impression die forging, is a metal forming process in which a workpiece that has been previously heated to a high temperature is pressed by means of countermoving form tools (forging dies).  The heated raw material which is approximately the shape or size of the … Read more
