What Is Network Infrastructure? 3 Things to Know

In the ever-evolving world of IT and digital information, it’s difficult to keep up with all the new tech. After all, your training may not be in tech. Why should you have to know everything about it?

While it’s easy to think this way, the fact is that the world relies increasingly on technology. Nowhere is this more true than in the business world. It benefits you to know at least the basics of how your business’ technology works.

To help you with this, we’re setting out to tackle one question: “What is network infrastructure?” If you don’t know, then great! In this article, you’ll learn three essential facts about this critical tech.

What is Network Infrastructure?

The definition of network infrastructure is the first thing we’ll cover. Simply put, network infrastructure connects several devices using a router.

This connection takes place through either wired or wireless means. This depends on the size and scope of the network. Network infrastructure also consists of the hardware and software that allow for connectivity.

Now that you know the network infrastructure definition, you may be wondering: “How does network infrastructure work?” Typically, network infrastructure breaks into three categories: hardware, software, and services. We’ll cover more about this in the next section.

How Does Network Infrastructure Work?

Network infrastructure utilizes three basic categories to form an interconnected system. We’ll break down what sorts of things belong to each category below.


The sort of things you’d see in a network’s hardware are numerous, but we can include some examples. Cables, wireless routers, switches, LAN cards, and other equipment would fit the hardware section.

Things get a little more complicated and diversified when we get to network software. However, there are still universals that most network infrastructures include.

Among those universals are network security applications, firewalls, and network operations. Other operating systems and network infrastructure management resources would fall into this category as well. 


Service is the final category of network infrastructure. It includes things like IP addressing, which identifies an individual device on an IP network. Other service-related things include wireless protocols, satellites, and more.

Benefits of Network Infrastructure

There are innumerable benefits to maintaining a business network infrastructure. For one thing, a solid infrastructure enhances your efficiency as a business.

By allowing for maximum communication, these systems guarantee an increase in productivity. They also possess tremendous scalability.

If you know how to manage network infrastructure, it can grow with your business without ever needing replacement. It’s also more cost-effective. A consistent infrastructure makes your network running costs far more predictable.
