A reliable network is the backbone of any business today, enabling communication with employees and customers, connecting to cloud-based platforms and apps, sharing and storing data, operating systems, and more.

Two of the most common network devices used in business infrastructures are the router and the switch. They might seem similar at first glance, but the two serve fundamentally different purposes in a business network. Understanding these differences can often be the deciding factor in choosing the right network devices and building the most reliable infrastructure. At NOK Smart, we know it is essential for businesses to make the right choices when building their systems and infrastructures around the most suitable hardware and network equipment to support their operations.

What Is a Router?

A router is a networking device that connects multiple networks.

Typically, a router will be used to connect a business’s network to the internet. In other words, the router allows data to travel from one network to another by determining the best path for transmitting that data.

For example, if you need to access a certain cloud-based business application, your router will make sure the data packets reach the right destination so you can view the application correctly.

Modern-day routers can also offer additional features and options depending on the specific hardware and setup. Those can often include additional levels of security, traffic control and management, options for establishing a secure connection, and much more.

Therefore, a router typically serves as an intermediary or a gateway between networks.

What Is a Network Switch?

While the router is used to connect networks, a switch is a device that connects end-users or devices on the same network.

A switch connects computers, printers, servers, IP phones, access points, and other devices using Ethernet cables. It receives data from one device connected to it and then sends that data to the appropriate destination on the same network.

Thus, network switches are often used in businesses to connect multiple devices.

Routers vs. Switches: What Is the Difference?

As stated, the router connects networks, and the switch connects devices within a network.

A good analogy would be to think of a router as something that connects multiple offices in different locations, whereas a switch would help employees within that office communicate with each other.

Below is a table outlining the most important differences between the two devices.

Router Switch:

• Connects networks; connects devices
• Typical use: Internet and network connection; local connection
• Typically connects networks. Devices (computers, printers, etc.)
• Typical role: Gateway device; core device
• Typically connects to WAN and LAN: Ethernet/LAN
• Traffic direction: Between networks; within a network

It is paramount to note that the two networking devices complement each other and are often used together in a business setting.

How Routers and Switches Work Together

A typical business infrastructure will feature both a router and one or more switches. Let’s imagine an average business office with around 50 employees. Each employee will most likely have a computer, and the office may also have printers and IP phones. Furthermore, many businesses have access points, servers, and other devices that need to be connected to the network. The switches are used to connect all of these devices. Then, the router is used to connect that network to the internet or another network.

The network then becomes a single unit, with all the devices connected to it being able to communicate with each other reliably.

This becomes especially important as a business grows or moves into a bigger office. More employees and more devices will generate more traffic and require more ports. Therefore, the importance of switches and routers, specifically, increases.

Managed vs. Unmanaged Switches

It is also important to note that there are managed and unmanaged switches, and the two can often serve different purposes. An unmanaged switch is typically used in a small office or at home to connect a few devices. A managed switch offers more features and is usually used when businesses need more control and flexibility.

In terms of choosing between the two, there is no definite answer. It often comes down to what the business needs.

Why Choosing Network Hardware Matters

When it comes to choosing the right network hardware, it is important to keep in mind that there is no one-size-fits-all solution. When choosing between switches, routers, and other network devices, it is important to analyze your business’s current needs and future goals.

For example, a small office setting with a handful of devices will have much lower demands than a large office with hundreds of employees, dozens of devices, servers, IP phones, security cameras, and more. In addition to the number of devices, other factors that might affect the choice of the network hardware include:

• The number of connected devices
• The internet connection
• The bandwidth
• Number of users
• Business applications used
• Level of security needed
• Scalability needs
• Growth prospects
• Supported hardware
• Maintenance and support needs

Taking all of the relevant factors into consideration will help you avoid underperformance and additional expenses due to the need for updates or replacements later.

When Does a Business Need a Better Router or Switch?

It is also important to keep in mind that not every problem is related to the ISP. Sometimes, the issue is the incorrect or outdated hardware. Businesses should consider investing in new switches and/or routers if they frequently encounter network-related issues, such as disconnections and slow performance. A higher number of connected devices, insufficient number of Ethernet ports, traffic congestion, and more can also be signs that a business may benefit from upgrading its network hardware. Finally, as stated earlier, growing operations usually call for more network ports.
