IoT and the evolution of networking


Since 1940, when the first teletype message1 was sent and received back by the same means, humans have been working to develop and improve networking capabilities—and find new ways to connect. However, the popularity of networking has exploded in recent years, thanks to the Internet of Things (“IoT”).

What is IoT?

IoT means connecting any device to the Internet—sensors, activators and smart devices that will intercommunicate and generate a smart way of living. In short, IoT is a huge network of things that are connected.

IoT is popular because of the idea of Big Data. Everyone is collecting information and IoT allows all the technologies that are being built around Big Data to work together and provide day-to-day solutions.

IoT applications

The implications of IoT are endless for our work and lives. From sensors in buildings, to electronics, to the day-to-day devices we use, to cloud services, everything has the potential to be connected. Here are just a few of the many possible IoT applications that are changing our daily lives.

Smart homes. Smart homes are one of the most popular IoT applications, allowing you to control your home’s functions remotely. Smart homes allow you to turn on the heat or air conditioning before you arrive home, or lock your doors after you’ve left home if you’ve forgotten.

Wearables. Are you wearing a smart watch or fitness tracker? Wearables means anything you’re wearing that collects data about you and provides insights.

Smart cities. IoT also has the potential to create smart cities, which can help city dwellers with traffic congestion, pollution, even finding a parking spot!

Smart retail. IoT can help retailers to improve customer experience in and out of store through communicating with smartphones and beacon technology.

Connected cars. Connected cars will optimize the driving experience.

Many other IoT applications, like smart agriculture, connected health, and smart supply chain also have the potential to change how we live and work.

The networking foundation and your career

Although networks are beginning to go wireless and everyone is talking about IoT, the foundations of networking are the same.

If you’re thinking about a networking career, you need to understand how a network is configured. You need to know the basic concepts of how the two devices that are connected with each other are transmitting information and communicating with each other.

Even with the move towards IoT, it’s still critical to understand what networks look like, and how routers and switches have evolved to support new devices and ways of communication.

Cisco is one of the largest network providers in the world. Sheridan has partnered with Cisco to offer a Certified Cisco Network Associate program. Upon completion of the program, you’ll be eligible to write the Cisco certification exams at a discounted rate.
