Amwoga Khalwale What Is BJT (Bipolar Junction Transistor)? A bipolar junction transistor (BJT) is a three terminal electronic device that amplifies the flow of current. The bipolar junction transistors are formed by sandwiching either n-type or p-type semiconductor layer between pairs of opposite polarity semiconductor layers. In bipolar junction transistor (BJT), electric current is conducted by both … Read more
In computer science and engineering, finite state machines (FSMs) serve as essential tools for modeling and analyzing systems with discrete behaviors. Among the diverse range of FSMs, the Mealy machine and Moore machine stand as two major variants, each exhibiting various characteristics and applications. While both machines share the common foundation of a finite set … Read more
Array and Linked Lists are types of data structures. A data structure is a method for organizing a set of data. The structure is defined by how the data is stored and how operations, such as data access, insertion and deletion are performed on the stored data. Data structures are essential tools for programmers, as … Read more
What Is Holography? Holography is the science and practice of making holograms. A hologram on the other hand, is a physical structure that uses light diffraction to make an image. A holographic image can be seen by looking into an illuminated holographic print or by shinning a laser through a hologram and projecting the image … Read more
What Is a Colorimeter? A colorimeter is a light-sensitive instrument used for measuring the transmittance and absorbance of light passing through a liquid sample. The instrument measures the intensity or concentration of the color that develops upon introducing a specific reagent into a solution. There are two types of colorimeters, color densitometers and color photometers. … Read more
An interrupt is said to be masked when it has been disabled or when the CPU has been instructed to ignore it. In this regard we have two classes of interrupts maskable and non-maskable interrupts. Maskable Interrupt A maskable interruptis a hardware interrupt that may be ignored by setting a bit in an interrupt mask … Read more
Monocot & Dicot Seeds Flowering plants generally referred to as angiosperms, fall into two classes, based on the number of cotyledons or seed leaves, within their seeds. For monocotyledons, also referred to as monocots, seeds contain only one cotyledon and when a monocot seed germinates, it produces a single. It is usually long and narrow, … Read more
The intestines are a long, continuous tube running from the stomach to the anus. Most absorption of nutrients and water happen in the intestines. The intestines include the small intestine, large intestine and rectum. What Is Small Intestine? The small intestine also referred to as small bowel, is an organ in the gastrointestinal tract where … Read more
What Are R-Selected Species? R-selected species, also referred to as r-strategist, are species whose populations are determined by their maximum reproductive capacity (biotic potential). R-selected species thrive in unstable habitats such as freshly burned grasslands, vernal ponds, carrion or forests characterized by canopies that open abruptly such as when a forest’s tallest tree has been … Read more
What A Is Food Chain? A food chain is a descriptive diagram including a series of arrows, each pointing from one species to another, representing the flow of food energy from one feeding group of organisms to another. There are two types of food chains, they include: Grazing food chain Detritus food chain The grazing … Read more
