Importance of Networking and Communication Systems in Electrical Engineering

In today’s technology-driven world, it’s more important than ever for electrical engineers to have a strong understanding of networking and communication systems. With the vast majority of devices now connected to the internet, these systems play a critical role in keeping everything running smoothly.

From ensuring that data is transmitted correctly to ensuring that devices are properly synchronized, electrical engineers must be able to design and maintain complex network systems. In this blog post, we’ll take a closer look at the importance of networking and communication systems in electrical engineering. We’ll also touch on some different aspects of networking and communication systems, including their benefits, challenges, routing design, and data transmission protocols. So whether you’re an aspiring engineer or a veteran looking to brush up on your knowledge, keep reading!

Network Protocol Used for Data Transmission

Network Protocol Used for Data Transmission

In order to send and receive data, computers need to use a common network protocol. The most common network protocol used for data transmission is the Transmission Control Protocol/Internet Protocol (TCP/IP).

Both protocols are collectively written as TCP/IP. The network protocols are used in all communication and networking processes without users knowing about them. These protocols enable the secure and encrypted transmission of data between servers and different devices. Whether you send an email, search online, watch YouTube videos, or scroll a website – networking and communication systems are always there.

The OSI (Open System Interconnection) model is a widely accepted theoretical structure that defines how modern-day networks are modeled or formulated. The OSI network model is based on 7 layers, each with different network protocols.

The table below shows network protocols used for the secure and reliable exchange of data between all layers and the network:

Data Transmission and Routing

Data Transmission and Routing

The routing is carried by one of the essential components of a network called the Router. When we create networks, we generally segment routing into two different components

  • Host
  • Router

Routers deal with traffic flow between networks, but hosts are responsible for various decisions and actions long before the packets reach the network. Most of the routing protocols used in networking and communication are intended to find optimized routes to destinations.

On the other hand, hosts direct all traffic leaving the local area network to the default gateway. The default gateway is responsible for routing the packets to the right destination. But most importantly, before sending the packet, a host processes its routing table.

The modern Ad hoc routing approach is not supported by mainstream network frameworks. It is used in applications that use sensor-based communication systems, networking and communication systems used in warfare & defense systems, and disaster response systems that activate when a network goes down. The nodes in these networking and communication systems ensure traffic flow to other nodes.

Benefits of Computer Networking

Below are some notable advantages of computer networking and communication systems.

  • Networks allow people to communicate effortlessly with other people via video calls, messaging apps, social media platforms, email services, etc. Without networks, there will be no internet and without the internet, there will be no communication.
  • Modern networking and communication systems have a high level of security and industry-tested data transmission protocols. People can share their sensitive information with the right person or business entities without fear of getting it leaked. Cloud technology is the most trending example of modern network systems. Cloud computing allows you to store all resources and information in a centralized location that you can access anytime. It eliminates the chances of storing sensitive data locally.
  • You can secure your data, applications, and files on a network with special authorization and authentication protocols. Multi-factor verification is an example of a modern authentication technique that requires users to provide multiple verification identities or passwords to access the system.

Difficulties With Networking

With great powers come great responsibilities. Apart from its advantages, some risks and challenges are associated with networking and communication systems, such as:

  • Network infrastructure can go down due to power failure, natural disasters, system errors, or human mistakes. The unavailability of service or downtime can cause a significant loss in productivity and monetary resources. Therefore, consistently testing, monitoring, and maintaining the network is necessary to ensure fewer chances of failure.
  • The capital investment required to build an in-house network infrastructure involves procuring high-end hardware equipment and hiring skilled networking experts. The total cost depends on the scale of the business and the resources used to frame the infrastructure. Using cloud services and SaaS products is one of the effective ways to dodge the need for an in-house network.
  • The total financial burden caused by cybercrime in 2022 is expected to reach USD 7 trillion by the end of 2022. According to Forbes, there is a 93 percent chance for your organization that a cracker can intrude into your private network and gain access to critical information and resources. The solution is to adapt enterprise-scale network security and hire/outsource skilled cybersecurity experts to safeguard your networking and communication system. But the chances of cyberattack will be likely to exist even though.


Networking and communication systems are two essential aspects of electrical engineering. Electrical engineers need to know how to network systems together in order to create efficient and reliable communication networks. In addition, electrical engineers also need to be able to design and analyze communication signals. By understanding networking and communication principles, electrical engineers can create more efficient systems that better serve the needs of their customers.

The most demanding communication and networking skills can be acquired by studying electrical and computer engineering.
