What is digital network technology?
More than ever before, data communication and networkingis providing innovative solutions to address social, environmental and economic challenges by enhancing efficiency and enabling both intensified network usage and more well-informed decisions.
Data networks serve as a catalyst in the development of an open marketplace that is always available to any consumer of the digital infrastructure. But first let us understand what digital networking concepts are.
A digital network is the one that incorporates both digital switching and digital transmission. Digital networks have marketplaces, platforms, data networks, communications networks, and at the center of it all, social media. Communication networkprovides an extensible, strategic platform that allows IT to streamline operations, reduce costs, detect and contain threats, and continuously align the network to business needs.
What is data network?
Data network comprises of electronic communications process that allows for the orderly transmission and reception of humongous data. Unlike audio or voice network, this type of network is configured be used for data communication only. This network consists of a particular number of nodes or stations connected by various communication channels.
Typical network topologies include six main types of topologies – bus topology, mesh topology, ring topology, star topology, tree topology and hybrid topology.
Different types of data networks
At present, there are 2 types of data networks that are in operation – private data network and public data network
Private data network – This is a local network that is designed to allow for the transmission of data between the various departments within a given entity, such as an enterprise. All the locations could be included in the form of network nodes. These nodes are able to communicate through a common server that functions as a repository for data files used throughout the business. In some cases, these private data networks allow for data sharing between several companies within the same industry.
In private data networks, connections are made by creating virtual private network (VPN) or by provisioning the connections through a communications carrier.
They are often used for home, business, or school Wi-Fi networks, or mobile hotspots for security and to preserve bandwidth.Private networks have various security measures in place to prevent any unauthorized connections.
Public data network – This type of network will be broadly accessible to both retail and corporate clients of a given communication network. The setup of public data networks usually involves multiple servers and connects to the network through various processes.
Some of the public networks like public Wi-Fi require a password before a connection is made, while some are open and do not require password. However, some public networks do not require password to connect but require login using web browser.
When information flows between two devices connected within communication networks then the process is called as data transmission. Now let us understand various data transmission modes to understand networking concepts in a better way. The physical layer primarily decides the direction of data flow and how it reaches to the receiver system or node. There are different data transmission modes based on the direction of exchange, synchronization between transmitter and receiver and number of bits sent in a computer network.
Based on the direction of information exchange, there are three types of data transmission modes:
Based on synchronization between the transmitter and the receiver, there are two types of data transmission modes:
Based on number of bits sent simultaneously in a network there are two types of data transmission modes:
Why does digital networking matter?
Digital transformation has made place in every sphere of life, with new processes and product development moving ahead at tremendous speed.
Networking impacts everything, but the legacy static networks of the past are no longer sufficient for companies embarking on digital-transformation plans. Now the networks must evolve. They must have improved security and embrace software-defined networking (SDN) as it supports on-going changes in a fast manner across the network to address challenges posed by digital transformation.
Today’s networks also need to be highly agile so that changes can be incorporated across network in real time in order to keep up with the business demands. This agility is achieved in digital networks where controls are centralized and configuration changes can be made once and then propagated across the entire network instantly. This agility cannot be achieved in legacy networks.
Digital networks can also provide tremendous security. IT enterprises now include Cyber security as their topmost priority and second biggest investment priority after cloud when it comes to digital transformation. As digital network infrastructure sees all data traffic flow, it can gather data and indicate a security breach, if any. Moreover, digital technologies have the potential to attain a sustainable recovery from the pandemic. This could also include accelerating the digitization of government services.
How do digital networks work?
There are specialised devices including switches, routers, and access points that form the core of digital networks. Switches connect and secure devices like computers, servers, and others to home or enterprise network, while access points are switches that connect devices to networks without wires. Routers are used to connect networks to other networks and analyse data to be sent across a network. One main difference between switches and routers is the way they identify end devices. Nowadays, most of the switches perform some level of routing function also.
Evolving computer networks
Organizations, globally, are embarking on their digital transformation journey andtheir networks are critical to this transformation. Newer types of network architectures are evolving to meet these requirements:
- Software-defined (SDN)–In this network, data traffic is routed through centrally controlled software-based mechanisms. This result in high agility in response to requirements for digital age.
- Intent-based –This network one is built on SDN principles.This not only introduces agility but also sets up a network to achieve desired objectives by automating operations extensively, analysing its performance, providing high security, and integrating with various business processes.
- Virtualized -This type of network is achieved by logically partitioning the underlying physical network infrastructure, to create multiple “overlay” networks. Each of these logical networks can be adjusted to meet specific security, quality-of-service (QoS), and other requirements.
- Controller-based -In this type of network, controllers automate networking functions by translating business intent to device configurations, and they monitor devices constantly to help ensure performance and security. Controllers are used to simplify operations and help enterprises respond to changing business requirements.
- Multi-domain integrations -These networks are used by larger enterprises and communicate with one another through their controllers. Multi-domain integrations generally involve exchanging relevant operating parameters to ensure desired business outcomes, that span network domains, are achieved.
Features of digital networks
Traditional network architecture lack scalability for the digital era, however, digital networks come equipped with following features:
Centralised management – Digital communication networks design and assure network services through cloud-enabled centralised management. They enable end-to-end network services for on-premise and in the cloud.
Automation – Enable complete automation of network infrastructure across the access network
Security – Digital networks are able to mitigate threats with end-to-end network segmentation. With the help of analytics these networks are able to identify threats even in encrypted data traffic.
Virtualisation – For enabling deployment of network services on any platform and connect users to various applications with one seamless network.
In addition, a digital network platform offers limitless scalability and affordability and possesses capabilities much beyond communication networks. The embedded compute and storage supports clients with intelligent insights.
A digital communication network also provides an automated environment in which intelligent machines can communicate with each other with improved reliability and efficiency such as in the case of self-driving vehicles.

What are the three key digital networking technologies?
The three key digital technologies are client/server computing, packet switching, and development of communication standards Transmission Control Protocol/Internet Protocol (TCP/IP). In client/server computing, some of the processing power is located within small, inexpensive client computers. Packet switching involves slicing digital messages into packets, sending those packets along different communication paths, and then reassembling those packets after they arrive at their destinations. TCP/IP is a set of rules and procedures governing transmission of information between two points in a network.
What are the 5 components of a network?
The components of a data communication network are divided into hardware and software. The hardware components comprise of server, client, peer, transmission medium, and connecting devices while software components include operating systems and protocols.
What is data communication and network?
A system of interconnected computers that facilitates information sharing is termed as computer network. The data could be easily transferred across different nodes through data communication network. The data signal could be easily transmitted from one point to another in a network. There are different sets of wireless methodologies for data communication
What are data network effects?
A data network effect is realised when a product’s value grows as a result of more usage via the accretion of data. Direct network effects occur when the value of a product or service to your user increases exponentially with the number of the other users using the same product or service. Some examples of a one-sided network effect are WhatsApp and Skype.
What are the 5 components of data communication?
The 5 components of data communication include data, sender, receiver, transmission medium and protocol.
The 3 major categories of data network are Local Area Network (LAN), Metropolitan Area Network (MAN), and Wise Area Network (WAN). Nowadays, other types of networks are also used like Campus Area Network (CAN), Storage-Area Network (SAN), and System Area Network (SAN)
