Amwoga Khalwale What Is G. fast? The name G.fast is an acronym for Fast Acess to Subscriber terminals. The letter G, stands for the ITU-T G series of recommendations. G. fast is a digital subscriber line (DSL) protocol standard for local loops shorter than 500 m, with performance targets between 100 Mbit/s and 1 Gbit/s, depending on … Read more
Microprocessor A microprocessor is an integrated circuit (IC) which performs the instructions and tasks involved in computer processing. It is a controlling unit of a micro-computer, fabricated on a small chip capable of performing Arithmetic Logic Unit (ALU) operations and communicating with the other devices connected to it. Microprocessor consists of an ALU, register array … Read more
Nuclear Fission Nuclear fission of heavy elements was discovered in 1938 by German Otto Hahn and Fritz Strassmann. Nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei. This process usually produces free neutrons, gamma photons and releases a … Read more
In programming, a loop is an instruction that repeats until a specified condition is reached. In a loop structure, the loop asks a question, if the answer requires action, it is executed. The same question is asked again and again until no further action is required. Each time the question is asked it is referred … Read more
What Is Cookie? A HTTP cookie also referred to as internet cookie, browser cookie, web cookie or simply cookie, is a small piece of data sent from a website and stored on the user’s computer by the user’s browser while the user is browsing. While cookies serve many functions such as storage of password, preferences, … Read more
Optic Disk (Optical Storage Device) Optical storage is the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, often a beam of light focused on a spinning optical disk. Therefore, an optic disk is any computer disk … Read more
What Is Elastic Collision? Elastic collision is a type of collision in which the total kinetic energy is conserved. What this means is that, the total kinetic energy of the colliding bodies after collision is equal to their kinetic energy before collision. In a perfectly elastic collision, there is no net conversion of kinetic energy … Read more
What Is Fresnel Diffraction (Near-field Diffraction)? Fresnel diffraction also referred to as near-field diffraction is a form of diffraction which occurs when a wave passes through an aperture and diffracts in the near field, causing any diffraction pattern observed to differ in size and shape depending on the distance between the sources of the obstruction … Read more
Capstan and Turret lathe were first developed in the United States of America in 1960 by Whitney and Pratt. They are used for repetitive production of duplicate parts in the minimum time possible. The main parts of a capstan and turret lathe include: Bed Headstock Cross slide and saddle The turret saddle and auxiliary slide … Read more
What Is Semaphore? Semaphore is a variable or abstract data type used to control access to a common resource by multiple processes in a concurrent system such as multitasking operating system. Semaphore concept was invented by Dutch computer scientist, Edsger Dijkstra in 1962. Semaphore is typically a variable used to solve critical section problems and … Read more
