OSI stands for Open System Interconnection is a reference model that describes how information from a software application in one computer moves through a physical medium to the software application in another computer. Functions provide better modularity for your application and a high degree of code reusing. A function is generally denoted by f (x) where x is the input. OSI model was developed by the International Organization for Standardization . Specifically, a function contains a unit of code that works on various inputs, many of which are variables, and produces concrete results involving changes to variable values or actual operations based on the inputs. These functions are also known as the input function, process function, output function, and storage function, respectively. : c) storing data temporarily (WUv A'vqxfve . A computer's Basic Input Output System and Complementary Metal-Oxide Semiconductor together handle a rudimentary and essential process: they set up the computer and boot the operating system. So that this will makes easy for a user to understand that Code. Q.
