 The Open Systems Interconnection (OSI)  was developed by the International Organization for Standardization in 1984 to enable different types of networks to be linked together.  The model contains seven layers, as shown in the Figure below. These layers describe networking functions from the physical network interface to the software applications interfaces. The intent of the OSI model is to provide a framework for networking that ensures compatibility in the network hardware and software and to accelerate the development of new networking technologies.  Physical layer Provides the electrical and mechanical connection to the network. Examples of technologies working in this layer are Electronic Industries Alliance/Telecommunications Industry Association (EIA/TIA)–related technologies, UTP, fiber, and network interface cards (NICs).  It uses topologies: BUS, STAR, RING, MESH Communication modes: Simplex, Half Duplex, Full Duplex Hardware including ne...

JOB OPPORTUNITIES IN NETWORKING A short discussion can be on: Provide job opportunities that has taken your interest based on the video watched...  WHAT IS A NETWORK?  A network is  a group of computers & other devices that are connected by some type of transmission media. A network can be as small as two computers connected together by a cable or can even be made up of  billions of computers & other devices connected across the world through radio waves, satellites, infra red beams, cable, wireless and even phone lines. The other devices can be referred to cell phones, personal computers, mainframe computers, printers, scanners, security cameras, vehicles and wearable technology devices.
