THE OSI MODEL: THE 7 LAYERS IN NETWORKING EXPLAINED

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...

FUNDAMENTALS OF NETWORKING

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. TYPES OF NETWORK Local Area Network (LAN) Metropolitan Area Network (MAN) Wide Area Network (WAN) Personal Area Network (PAN)

NETWORKING: PACKET TRACER - IoT

In simple terms the IoT is a connection of : networked sensors, actuators, and smart devices that collect and share data. Packet Tracer 7 contains many new features to support the IoT. This includes the addition of IoT devices that can be configured to react to certain environmental values such as sun, wind, rain, and humidity. These devices can be configured to take actions based on the changing environmental values, such as turning on lights or closing garage doors. The next parts of learning will include instructions to locate the IoT devices, to connect them to your network, to configure and modify scripts to make them function, and to control these devices remotely. Packet Tracer provides everything you need to create simulated smart homes, smart cities, and smart factories. CONFIGURE IoT DEVICES USING PACKET TRACER Packet Tracer has a wide variety of sensors and smart devices that will allow you to design smart homes, smart cities, smart factorie...
