WebDec 21, 2024 · Chloe Tucker. This article explains the Open Systems Interconnection (OSI) model and the 7 layers of networking, in plain English. The OSI model is a conceptual framework that is used to describe how a network functions. In plain English, the OSI model helped standardize the way computer systems send information to each other. WebIn networking, a packet is a small segment of a larger message. Data sent over computer networks*, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them. Suppose Alice is writing a letter to Bob, …
WebThe Internet has its origin in the ARPANET network sponsored by the U.S. Department of Defense starting in the 1960s. The ARPANET was a datagram store-and-forward network that the Department of Defense liked for its ability to reroute packets around failures. This feature makes datagram networks survivable.
