Amwoga KhalwaleWhat 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
Typhoon, Hurricane And Cyclone Cyclone, Typhoo and Hurricane can be describe as Tropical Cyclones, a tropical cyclone is a general term used by meteorologists to describe a rotating, organized system of clouds and thunderstorms that originate over tropical or subtropical waters and has low closed, low-level circulation. 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
In physical chemistry and material science, a mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids. One major characteristic of mixtures is that they can be separated into their components, since each part of the mixture has … Read more
What Is Kerberos? 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. It uses secrete-key cryptography and a trusted third party for authenticating client-server applications and verifying user’s identities. Users, machines and … Read more
What is Co-channel Interference? Co-channel interference (CCI) occurs in wireless communication systems, particularly in scenarios where multiple transmitters use the same frequency channel to communicate simultaneously. When this happens, the signals from different transmitters interfere with each other, degrading the overall quality of communication. In simpler terms, imagine several people talking at the same time … Read more
In organic chemistry, hydrocarbons are the simplest class of organic compounds and are composed solely of hydrogen and carbon. Hydrocarbons are generally divided into two classes, depending on the presence of a benzene ring, that is, aromatic compounds and aliphatic compounds also referred to as non-aromatic hydrocarbons. Aromatic Compounds Aromatic compound can be described … Read more
Solubility product is the concentration of ions of electrolyte, each raised to the power of their coefficients in the balanced chemical equation in a saturated solution. It is applicable only for saturated solutions and is constant for a solution at a given temperature. Ionic Product is the product of concentration of ions of the electrolyte, … Read more
What Is Nuclear Reaction? Nuclear reaction is a process in which two nuclei or nucleus of an atom and a subatomic particle (such as a proton, neutron or high energy electron) from outside the atom, collide to produce one or more nuclides that are different from the nuclides that began the process (parent nuclei). In … Read more
