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. Home RF: ...

What is Topology  Network Topology is the arrangement of the various elements links, nodes, etc. of a computer network. it is the topological structure of a network and may be depicted physically or logically. Topologies are divided into two types. One is called physical topology & another one is logical topology. Physical topology is the placement of the various components of a network, including device location and cable installation, while logical topology illustrates how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, or signal types may differ between two networks.   Topology There are a number of reasons to understand about Topology: The network topology impacts performance The network topology is a factor in determining the media type used to  cable the network The networking topology impacts the cost of cabling the network. Some access m...
