Network bridge in the context of Network nodes

Remote work (also called telecommuting, telework, work from or at home, WFH as an initialism, hybrid work, and other terms) is the practice of working at or from one's home or another space rather than from an office or workplace.

The practice of working at home has been documented for centuries, but remote work for large employers began on a small scale in the 1970s, when technology was developed that could link satellite offices to downtown mainframes through dumb terminals using telephone lines as a network bridge. It became more common in the 1990s and 2000s, facilitated by internet technologies such as collaborative software on cloud computing and conference calling via videotelephony. In 2020, workplace hazard controls for COVID-19 catalyzed a rapid transition to remote work for white-collar workers around the world, which largely persisted even after restrictions were lifted.

In networking, a node (Latin: nodus, 'knot') is either a redistribution point or a communication endpoint within telecommunication networks or computer networks.

A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. In data communication, a physical network node may either be data communication equipment (such as a modem, hub, bridge or switch) or data terminal equipment (such as a digital telephone handset, a printer or a host computer).

A cable modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fiber-coaxial (HFC), radio frequency over glass (RFoG) and coaxial cable infrastructure. Cable modems are primarily used to deliver broadband Internet access in the form of cable Internet, taking advantage of the high bandwidth of a HFC and RFoG network. They are commonly deployed in the Americas, Asia, Australia, and Europe.

A network switch (also called switching hub, bridging hub, Ethernet switch, and—by the IEEE—MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.

A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches.
