Topology is the structure that describes how devices in a Network are connected.Bus Topology: Directly connects all devices to network i.e utilises a single Physical medium for Data transmission between devices.Star Topology: Connects all devices in network through a Central Network connecting device such as Hubs & Switches.Advantage of Bus Topology is that less connecting cable is used.Advantage of Star Topology is that Network can function in case one or more devices fail.Disadvantage of Bus Topology is that whole Network goes down if one device fails.Disadvantage of Star Topology is that it requires physical connecting medium from Central device to the connecting device i.e more expensive.
Wi-Fi
Output devices are connected to the CPU through the northbridge and southbridge, (collectively called the chipset) but they connect to different devices. The northbridge connects to the graphics output, while the southbridge connects to all other output devices (sound, storage, network, and others).
a hub is a central point in a network through which all the wires pass, a switch connects more than 2 LAN networks
a computer network in which devices are connected through copper wire cables
This is the definition of a computer network. Devices such as routers and bridges create logical network subnets and network domains that computers, printers, and other devices can connect with to join the network.

the devices which connects different computer systems through a single physical conections.
The device that connects one network to another is Router or Multilayer Switches but by default multilayer switches will not enable the services connecting two different network we should provide instruction through CLI.
Computer network devices also known as communication devices and they constitute a data communication network. These devices are routers, switches, hubs, LAN cards, gateway, modems, hardware firewall, CSU/DSU, ISDN terminals and transceivers. In an Ethernet or WAN network, the data communication cannot be performed without these devices. Being an IT professional or a network administrator, you must have the good understanding of these devices.
Video conferencing connects individuals in real time through audio and video communication over a Low broadband network, enabling visual meetings and collaboration with digital documents and shared presentations. In the early days, participants used to connect in central meeting rooms with video conference hardware and now, the new technologies allow participants to connect remotely over a network through multiple devices like laptops, desktops, smart phones and tablets.
