Amwoga Khalwale Top-down and bottom-up approach are both strategies of information processing and knowledge ordering, used in a variety of fields including software, humanistic and scientific theories and management and organization. In practice, they can be seen as a style of thinking, teaching or leadership. In this article get to understand the underlying difference between top-down and … Read more
What Is A Series Circuit? A series circuit is a circuit in which resistors are arranged in a chain, so that current has only one path to take. The current is the same through each resistor but voltage is dropped (lost) across each of the resistances. In a series circuit, the sum of the voltages … Read more
What Is IPv4? IPv4 (Internet Protocol Version 4) is the fourth revision of the Internet Protocol (IP) used to identify devices on a network through an addressing system. The internet protocol is designed for use in interconnected systems of packet-switched computer communication networks. IPv4 is the most widely deployed internet protocol to connect devices to … Read more
What Is Two-Tier Database Architecture? Two-tier architecture is a software architecture in which a presentation layer (application interface) runs on a client (PC, Mobile, Tablet etc) and a data layer or data structure gets stored on a server. Separating these two components represents two-tier architecture rather than single-tier architecture. There is direct communication takes place … Read more
What Is Hydrostatic Pressure? Hydrostatic pressure is the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Hydrostatic pressure increase in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above. What You … Read more
A filter is a circuit that removes or filter-out a specified range of frequency components. In other words, it separates the signal’s spectrum into frequency components that will be passed and frequency components that will be blocked. Filters can be classified in accordance with the general characteristics of the filter’s frequency response. If a filter … Read more
The terms, dominant and recessive describe the inheritance patterns of certain traits. The terms are useful concepts when it comes to predicting the probability of an individual inheriting certain phenotypes, especially genetic disorders. However, the terms can be confusing when it comes to understanding how a gene specifies a trait. In genetics, dominance can be … Read more
In computer science, a search algorithm is an algorithm (if more than one, algorithms) designed to solve a search problem. Search algorithms work to retrieve information stored within particular data structure, or calculated in the search space of a problem domain, with either discrete or continuous values. There are different types of searching algorithm, some of … Read more
What Is Natural Selection? Natural selection is one of the basic mechanisms of evolution, along with mutation, migration and genetic drift. Natural selection also referred to as “Survival of the fittest’’ is a process by which a species change over time in response to changes in the environment or competition between organisms, in order for … Read more
What Are LEDs? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. LEDs are comprised of compound semiconductor materials, which are made up of materials such as gallium arsenide (GaAs) and gallium phosphide (GaP). LEDs operate by electroluminescence, a phenomenon in which the emission of … Read more
