Amwoga Khalwale 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
What Is Balance Of Trade (BoT)? The balance of trade also referred to as commercial balance is the difference between the monetary value of a nation’s exports and imports over a certain period of time. The balance of trade figures shows whether the country had achieved to sell locally produced goods and services to foreign … Read more

The weakest tropical cyclones are referred to as … Read more
Unshielded Twisted Pair (UTP) Cables In UTP cable, conductors which form a single circuit are twisted around each other in order to cancel out electromagnetic interference (EMI) from external sources. Unshielded means no additional shielding like meshes or aluminum foil which add bulk is used. UTP cables are often groups of twisted pairs grouped with … Read more
