SWITCH VS ROUTER? HOW TO DECIDE WHAT YOUR BUSINESS NEEDS

What a Switch and a Router Are Used For

A switch (also called an ethernet switch) makes it possible for all of your devices to connect and communicate within your network. That includes your computers, printers, IP phones, point-of-sale registers, servers, and more—any devices that need to operate within your local area network (LAN).

If you’ve ever opened a document on your computer and then printed it on a printer located at the other end of the office, you have benefited from having an ethernet switch.

A router uses switches to create a high-performance LAN in which connected devices can access the internet or other networks. A router prioritizes devices and users, and efficiently directs traffic accordingly. It’s essential for maintaining seamless and quick network service.

Switch vs. Router: How Switches and Routers Work

A switch works by acting like a subway station for your internal network, transferring packets of data from one device to another.

Switches build a network within a layered architecture. The first layer, known as the “edge layer,” provides connectivity for all your devices. For smaller businesses, this layer of “routing switches” connects directly to your router, which in turn connects your business to the internet. Simply put, you cannot build a network for your business without switches.

For larger businesses, these switches connect to aggregation switches, which enable your network to scale.

There are two kinds of switches, unmanaged and managed.

• Unmanaged switches merely provide ethernet devices with network connections, essentially serving as basic connection ports that require no configuration. These switches typically have additional ports of connectivity in office and conference room environments.
• Managed switches offer much more customization, device transparency, and security for your network than unmanaged switches. Some types even provide a real-time network topology overview and status of every device plugged into the switch.

A router allows the devices on your internal network to connect to the internet and to each other. It connects the small network (made up by one switch) to other networks, expanding the network’s coverage and capacity. A router also decides which devices have priority on your network, and which switches the information will travel through on its journey from Point A to Point B.

If a switch is a subway station, then a router works like the terminal at Times Square where multiple subway lines converge and passengers can enter or exit the system as well as transfer between lines.

Which to Choose: Router vs. Switch for Your Business

When it comes to deciding if your business needs a switch or a router for connecting to and communicating within your network, which one does your business need—router vs. switch?

It can be confusing—which makes it difficult for many business owners to determine which device is right for their location—but the decision is actually nonexistent. Why? Because most of the time you don’t need to choose one or the other.

Most businesses are heavily dependent on the internet to conduct daily business. So many business functions require being connected to the internet via a router, such as:

• Making and approving online transactions
• Connecting devices and users to SaaS or cloud-based applications
• Completing credit card processing

However, businesses who have their own LAN also need at least one switch to connect all the devices and users together so information can freely flow from one to another.

In other words, smaller businesses without their own internal computer network can get by with just a router. Otherwise, businesses need both a router and at least one switch.
