Computer networking is a setup that joins a lot of separate computers together to exchange resources and information. Though, users can converse more readily because of the integration of computers and other gadgets.

Computer networks are collections of two or more linked computer systems. To create a network connection, you can utilize wired or wireless media. However, computers and tools connect networks via hardware and software.

There are several sorts of nodes in a computer network. A computer network can include servers, networking devices, personal computers, and other specialized or general-purpose hosts. Though they can be located using network addresses and host names.

In this article, we will go over computer networking and the many types of computer networks, their definitions, and operations, as well as the various types of node devices. So, let us go a little more into the matter.

What types of computer networking are there?

Accordingly, there are five types of computer networking design –

VPN (Virtual Private Network) – 

  • A network that is built by connecting public cables to a private network.
  • There are several solutions that allow you to build networks that use the Internet as a data transport channel.
  • Lastly, these systems use encryption and other security measures to guarantee that only authorized users can access them.

LAN (Local Area Network) – 

  • Systems interconnected in a tiny network, such as those in a small office or building
  • Computer Networking is reasonably priced.
  • It uses either Ethernet or Token-ring technology.
  • Using wires or cables that act as nodes, two or more personal computers can be connected.
  • Data transfer is quick and well-rated.

PAN (Personal Area Network) – 

  • The smallest computer networking system You may connect devices via Bluetooth or other infrared-capable gadgets.
  • Contrarily, it has a 10-meter connection range.
  • It has a coverage area of up to 30 ft.
  • PAN allows a single person’s personal gadgets to communicate with one another.

WAN (Wide Area Network) – 

  • A network that serves an entire nation or a greater population.
  • WAN also connects telephone lines.
  • The Internet is the world’s largest WAN, and government agencies mostly use it to manage data and information.

MAN (Metropolitan Area Network) – 

  • A computer Networking device that may link to other networks inside a city, such as a cable TV connection
  • It can be Ethernet, ATM, Token-ring, or FDDI.
  • It has a greater range.
  • This sort of network may link citizens to numerous organizations.

What is the process of computer networking?

In computer networking, nodes and connections are the fundamental building components. A network node can be either data communication equipment (DCE) like a modem, hub, or switch or data terminal equipment (DTE) like two or more computers and printers. A link is the channel of transmission that links two nodes. Physical links, such as cable lines or optical fibers, or open spaces utilized by wireless networks, are examples of links.

When a computer networking system is operating properly, nodes follow a set of guidelines or protocols that control the transmission of electronic data through the links. The computer network architecture determines the layout of these logical and physical components. Though, it specifies the physical components, functional organization, protocols, and processes of the network.

What are computer networks used for?

In the late 1950s, computer networks were set up for military and defense objectives. They had a restricted range of commercial and scientific uses at first and were first employed to transport data via telephone lines. With the introduction of internet technology, a computer network has become essential for businesses.

Therefore, modern network systems provide more than just connection. They are important for today’s digital transformation and company success. The underlying network’s capabilities have improved in terms of programmability, automation, and security.

Modern Computer networking services are capable of:

A virtual operation

Conceptually dividing the underlying physical network architecture allows for the creation of many “overlay” networks. Data may be delivered between the nodes in an overlay computer network across a number of different physical paths since the nodes are virtually connected. Many corporate networks, for example, exist alongside the internet.

Large-scale integration

Modern Computer networking service providers link geographically dispersed computer networks. These services may automate and monitor network processes to establish a single large-scale, high-performance network. According to demand, the demand may need scaling up or down of network services.

Quickly adapt to shifting circumstances

Software defines a large number of computer networks. It is possible to centrally route and manage traffic using a digital interface. These computer networks offer virtual traffic management.

Give data security

All networking systems include security features such as encryption and access control. To increase network security, third-party programs like firewalls, antimalware, and antivirus software can be integrated.

What are the various network typologies?

The following are the eight different types of network topologies:

Point-to-Point Topology – 

The simplest topology is point-to-point topology, which connects two nodes directly with a shared connection.

Bus Topology –

In a bus topology, all nodes are linked to a single line, known as the bus, and they make no other connections.

Mesh Topology – 

This kind of topology has at least two nodes and two or more pathways connecting them.

Ring Topology – 

Each node has a precise two-branch connection in this architecture. If one of the ring’s nodes fails, the ring is split and will no longer operate.

Star Topology – 

The central node, which transmits all messages received from any peripheral node to all other peripheral nodes within the Computer networking, including the originating node, connects the peripheral nodes in this network structure.

Tree Topology –

The connections between the nodes in this topology form a tree. The central node’s function in this architecture is flexible.

Line Topology – 

A “line” topology connects all of the nodes in a single straight line.

Hybrid Topology – 

This sort of topology occurs when two more topologies come together.

Conclusion 

An effective network boosts productivity, security, and creativity while minimizing overhead expenses. This is only possible with solid design and implementation, as well as a thorough understanding of the business requirements. Even though network development might seem entirely technical, it also involves commercial input, especially in the beginning. Computer Networking management also entails changing procedures and adapting to new technology.
