Types of IT Network Infrastructure

Okay, so we know what goes into IT network infrastructure, but did you know there are different types? The best choice for your business depends on your specific needs, size, and budget. Here are some of the main types you’ll encounter:

• Local Area Network (LAN): This is the most common type and connects devices within a limited area, like an office or a home. It's the network you use to share files, printers, and internet access.

• Wide Area Network (WAN): A WAN connects networks over a large geographical area, such as different offices in different cities or countries. The internet is a huge example of a WAN.

• Wireless Local Area Network (WLAN): As the name suggests, a WLAN uses wireless technology to connect devices. It provides flexibility and mobility, allowing users to access the network from anywhere within the coverage area. Wifi is an example of a WLAN.

• Virtual Private Network (VPN): A VPN creates a secure connection over a public network, such as the internet. It's often used by remote workers to securely access their company’s network.

• Cloud Network: This is a network that uses cloud computing services. It provides flexibility, scalability, and cost savings by leveraging the resources of cloud providers.

Choosing the right type of network infrastructure is critical. For example, a small business might do fine with a simple LAN and a few wireless access points. A multinational corporation, on the other hand, will require a complex WAN, VPNs for remote access, and possibly a cloud-based network for scalability. The decision depends on how much you rely on data and the geographical spread of your business.
