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.
