Amwoga Khalwale In fiscal governance and public finance, the terminologies used to describe various forms of financial charges imposed by governments can be confusing or are easy to misunderstand. In this article let us talk about the difference between a tax and levy, their roles, applications and implication. Before we begin, it is also important to understand … Read more
Malloc () The malloc () function stands for memory allocation. It is a function which is used to allocate a block of memory dynamically from the heap. The heap is an area of memory where something is stored. Calloc reserves memory space of specified size and returns the null pointer pointing to the memory location. … Read more
What Is Kernel? The Kernel is the central module of an operating system (OS). It is the part of the operating system that loads first and it remains in the main memory. Typically, every operating system has a kernel. The kernel is responsible for memory management, process and task management and disk management. It also … Read more
What Is Schottky Defect? A Schottky defect is a type of point defect in a crystal lattice named after a German physicist Walter H. Schottky who discovered it. In ionic crystals, this type of point defect forms when oppositely charged ions leave their corresponding lattice sites, creating a pair of vacancy defects. These vacancies are … Read more
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
