Wireless Networks Wireless networks are computer network that are not connected by cables of any kind In simple words. when two or more devices are connected without any networking cable, It is called wireless networking. From cell phone, to simple home wireless internet connection, Bluetooth and more, everything comes under wireless networking. Wireless Networks: Ir DA: Infrared Data Association Data Association has developed a standard where data is transmitted via Infrared light waves It is a protocol where beams are used in the Infrared light s spectrum. In case of Ir DA, as the data transfer is done through infrared, you can send data to one device at a time.   Bluetooth: Bluetooth uses 2.45 gigahertz radio waves to share data between devices. The technology is limited to a short distance of 10 ft but it can cross walls in order to transmit data This also communicates without wire. The figure shows the various Bluetooth versions.

  What is OSI? Open Systems Interconnection or OSI model was first proposed by International Standards Organization (ISO) to solve the multiple problems faced in telecommunication.    It is a conceptual model of telecommunication networking where the whole process is divided into seven effective layers. It synchronizes the whole process and helps one understand the interoperation of the diverse communication system under the standard protocol. The seven layers we are talking about are abstraction layers and each layer is connected to either one or two layers depending on its position. The interlinked layers serve one another to forward the communication process. Understanding the seven layers of OSI  Brief description of each of OSI Layers.      Layer 1: Physical Layer:               This layer is the primary layer of the OSI model and consists of connecting devi...
