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 networking devices, antennas, c

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 factories, and smart power grids

HOW CAN CLIENT / SERVER NETWORK MODEL BE A CHANGE FOR YOU??

WHAT IS CLIENT / SERVER? In the client-server network model (which is sometimes called the client-server architecture or client-server topology), resources are managed by the network operating system through a centralized directory database. The database can be managed by one or more servers, as long as they have the same network operating system. In the midst of a WINDOWS SERVER controls network access to a group of computers, this LOGICAL group is known as Windows DOMAIN . The centralized directory database that keeps user account information & security for the entire group of computers is called AD (Active Directory) . Each user on the network has his/her own domain level account assigned by the network administrator and kept in Active Directory . A user can sign on to the network from any computer on the network and get access to the resources that Active Directory allows. The process is managed by AD DS (Active Directory Domain Services) . A computer makes a re
