A transistor is a linear semiconductor device that controls current with the application of a lower-power electrical signal. Transistors are usually categorized into two groups: bipolar and field-effect. A bipolar transistor is a commonly used for amplification. The device can amplify analog or digital signals. It can also switch DC or function as an oscillator. Physically, a bipolar … Read more
What Is MAC Address? MAC (Media Access Control) address is a unique identifier that is assigned to every internet-connected machine that allows it to be identified when connected to a specific network. The use of MAC is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi and Bluetooth. A MAC address consists of six … Read more
What Is Process? In operating system (OS), a process is the instance of a computer program that is being executed by one or many threads. For example, when we write a program in C or C++ and compile it, the compiler creates binary code. The original code and binary code are both programs, and therefore … Read more
What Are Rods/Rod Cells? Rod cells are photoreceptor cells in the retina of the eye that function in less intense light conditions, they do not perceive color and fine details, a function performed by the other major type of light-sensitive cell, the cone cell. Rod cells are more sensitive to light and are almost entirely … Read more
What Is Fahrenheit? The Fahrenheit scale is a temperature scale proposed by a German physicist Daniel Gabriel Fahrenheit in 1724. It uses the degree Fahrenheit as the unit. The Fahrenheit temperature scale bases the boiling point of water at 212◦ and the freezing point at 32◦, the interval between the two being divided into 180 … Read more
What Is Osteoblast? Osteoblast is a large cell responsible for the synthesis and mineralization of bone during both initial bone formation and later bone remodeling. Osteoblasts are a major cellular component of bone, it form a closely packed sheet on the surface of the bone, from which cellular processes extend through the developing bone. They … Read more
Phagocytosis Phagocytosis also referred to as “cell eating“is the process in which particles, microbes or fragments of dead cells are engulfed and internalized usually by specific membrane receptors. The process of phagocytosis begins with binding of specific molecules on the surface of pathogen/particle. The cell membrane then extends around the target, eventually enveloping it and … Read more
In programming, data can be stored in data structures like graphs and trees. A tree is typically special form of graph i.e minimally connected graph and having only one path between any two vertices. In other words tree is a special case of graph having no loops, circuits and no-self loops. Graphs can have loops, … Read more
Wood can be described as a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material (a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as secondary … Read more
There are two popular types of architectures based on the instruction set. They are CISC (complex instruction set computing) and RISC (Reduced Instruction set computing). Let us discuss the underlying differences, advantages, disadvantages and similarities between these two architectures. What Is RISC (Reduced Instruction Set Computing)? RISC (reduced instruction set computer) is a computer that … Read more
