Network nodes are the endpoints, communication, or redistribution points over a network that can receive, create, store, and send data along distributed routes. - Network Node Definition
A network node can
be defined as the connection point among network devices such as routers, printers, or switches that can receive and send data from one endpoint to the other. - Types of network nodes
The interconnection between various communication devices through
different communication links can be defined as a network. The network is used to exchange, store, send, and retrieve data between network devices, also known as network nodes. Each network node acts as a connection point for data transmission, process recognition, packet switching, and network distribution. Generally, nodes are programmed to identify, process, and transmit data from one node to another. They can perform several functions based on the application and network. In a network,
multiple nodes are used. A node can be a computer, printer, switch, or router. Nodes highly depend on the referred network and protocol layer to form a network connection. Additionally, each node on a network includes a unique IP address. Nodes in a threaded environment can be divided into two roles: - Routers: The role of a router node is to transmit packets from network devices. It helps maintain easy and quick connections between devices struggling to connect
to the network and offers safe commissioning services.
- End device: The role of an end device is to connect and interact with a router.
Outlined below are the different types of network nodes based on the application and function in a distributed network. - Internet network nodes: The host computers are referred to as the physical network nodes in internet networks. These nodes can be recognized with the help of their unique IP
addresses; however, some data link equipment doesn’t include an IP address, such as WLAN access points.
- Data communication nodes: Data communication devices are physical nodes or communication devices such as switches, routers, hubs, bridges, modems, and more. These nodes are located between data communication circuits and Data Terminal Nodes (DTE), and the major role of these devices is to perform signal conversion, coding, and line clocks. Devices such as host
computers, digital telephones, printers, and servers act as DTE.
- Telecommunications: Telephone nodes can include a computer that provides intelligent network services or private or public telephones capable of exchanging information. Nodes in cellular networks have base station controllers. The primary function of these controllers is to control multiple base stations.
- LANs and WANs: LANs and WANs consist of physical nodes or devices and include
a unique MAC address for Network Interface Card (NIC). Such network devices include computers, wireless LAN access points, modems, and more.
- Distributed nodes: Distributed nodes refer to the nodes involved in a distributed network environment. They can be physical or virtual nodes and are used to maintain transparency within the network.
- Network nodes examples
Switches: The network devices that follow the OSI model to send and receive data packets over the network are known as switches. Multiple devices such as computers, printers, and modems can be plugged in a single switch with multiple ports. Switches can examine destination addresses and perform error checking during data transmission.
They support all modes of communication, including unicast, broadcast, and multicast and use packet-switching technology to send and receive the data from source to destination. Additionally, switches can manage networks. There are four types: - Managed switches
- Unmanaged switches
- PoE switches
- LAN switches
Bridges: The network devices that can connect more than two LANs to form a single more extensive network are known as bridges. The
process of collecting LANs with the help of multiple components is known as bridging the network. Bridges can be of two types: - Transparent bridge
- Source routing bridge
Other examples of network nodes: a computer, printer, or router. - What is network segmentation?
Network segmentation refers to splitting a computer network into smaller parts to improve network performance and security. Network node segmentation is the most effective technique for meeting increasing bandwidth demands. Although cable infrastructure increases bandwidth by reducing the size of the service area, segmenting nodes via splitting or adding
provides access to a larger portion of the network. Multiple successions of nodes can impact other areas of the network. It’s important to have an effective node segmentation strategy that enables you to use high bandwidth without any impact on other business-critical network areas. - How to discover network nodes
Network nodes can be discovered by automated tools capable of scanning network devices, automatically populating maps to clarify network topology, and creating visual displays to show the interconnection between the nodes. - How to map network nodes
Mapping your network is crucial to determine how your network is performing. This helps pinpoint bottlenecks and network issues. With the help of network performance monitoring tools, you can easily track the performance of your network, scan for nodes, and create network maps. Another method is network mapping that lets you visualize all the devices or
nodes connected to your network. It provides the information required to track the network's overall performance. Network mapping is one of the most effective ways to track your network. Generally, network mapping tools produce three types of maps: - Physical map: A diagram consisting of all the network elements, including plugs, ports, chords, and more.
- Logical map: A logical map shows the network topology and how the data flows between the
nodes.
- Functional map: This addresses the application traffic flow through the network.
Benefits of using network mapping tools: - Network mapping tools can automatically discover network topology or devices on a network using protocols such as ICMP, SNMP, CDP, and more.
- They can build multiple maps to save bandwidth, resources, and time.
- They can auto-detect and monitor new devices and unknown systems to maintain
up-to-date and accurate records.
- They can maintain multiple network maps to help you demonstrate compliance with regulatory needs such as PCI, HIPAA, SOX, and more.

What do you call the device that receives data from another device on the network?
Router. In regards to networking (network devices router), a router is a piece of hardware that receives, analyses, and forwards incoming packets to another network. Routers examine incoming packets to determine the correct target IP address and send the packet to that address.
What is a node in a network?
A network node can be defined as the connection point among network devices such as routers, printers, or switches that can receive and send data from one endpoint to the other.
Information and communications technology (ICT) is an umbrella term that includes any communication device or application, encompassing: radio, television, cellular phones, computer and network hardware and software, satellite systems, and so on, as well as the various services and applications associated with them, ...
Which device is used to connect network devices so they can communicate with one another?
Hubs connect multiple computer networking devices together. A hub also acts as a repeater in that it amplifies signals that deteriorate after traveling long distances over connecting cables. A hub is the simplest in the family of network connecting devices because it connects LAN components with identical protocols.
