What is node in computer network

A node can refer to any device that is connected to a network, such as a computer, printer, router, or switch.

A node is a fundamental building block of a larger system or structure in computer science. It is typically used to represent a unit of data in a data structure, a device on a network, or a processing unit in a distributed computing system. A node contains data and may have references or pointers to other nodes. The term "node" can be used in different contexts, but in general, it refers to a basic unit that can be combined with other nodes to create more complex systems or structures.

In simple terms, a node in computer science is a basic building block of a larger system or structure. It can refer to a unit of data in a data structure, a device on a network, or a processing unit in a distributed computing system. Think of it like a Lego block - it's a small piece that can be combined with others to create something bigger and more complex.

TYPE OF NODE IN COMPUTER NETWORK:

There are several types of nodes in a computer network -

• Hosts/End Devices: These are the devices that generate and consume data in a network. Examples of hosts/end devices include computers, smartphones, tablets, and servers.

• Network devices: These are devices that are used to connect end devices to the network and facilitate communication between them. Examples include routers, switches, hubs, and access points.

• Servers: These are specialized devices that provide specific services to the network, such as file sharing, email, web hosting, and database management.

• Gateways: These are devices that connect two or more different networks and allow them to communicate with each other. A common example is an internet gateway, which connects a local network to the internet.

• Network management devices: These are devices that are used to monitor and manage the network, such as network monitoring tools, network analyzers, and configuration management tools.

The type of node used in a network depends on the specific requirements of the network and the tasks it needs to perform
