A voltage regulator is an electronic device which can sustain the voltage of power supply within required limits. When a reliable and steady reliable is required, then the voltage regulator is the preferred device. It gives a fixed output voltage that remains constant for any changes in an input voltage or load conditions. It acts … Read more

What Is System Unit? The computer system unit is the enclosure for all the other main interior components of a computer. It is also referred to as the computer case, computer chassis or computer tower. Cases are typically made of steel or aluminum, but plastic can also be used. While most computer cases are rather … Read more

What Is Opening & Closing In Image Processing? Opening and closing are two important operators from mathematical morphology. They are both derived from the fundamental operations of erosion and deletion. Like those operators they are normally applied to binary images, although there are also graylevel versions.  Opening is generally used to remove small objects from … 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 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

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
