Types Of Networking: An Overview

Networking, at its core, refers to the set of hardware, systems, and protocols that come together to make communication between computers or computer systems possible. There are several types of networking, each designed to meet specific requirements in efficiency, geography, and security just to mention a few. In this article, we will discuss the major types of networking: Local Area Networking (LAN), Wide Area Networking (WAN), Metropolitan Area Networking (MAN), Personal Area Networking (PAN), and Virtual Private Networking (VPN). Interestingly, each of these networking types plays a crucial role in a well-structured and secured IT ecosystem.

Local Area Networking (LAN)

The most commonly known type of networking is LAN. It connects devices in relative close proximity such as within a building or a group of buildings like a school, café, or office. For instance, a University might use a LAN to link computers in a particular department so files and other information can be shared. LAN provides high-speed data transfer and they are pretty secure considering their contained environment, but their range is quite limited and they do not support a large number of devices.

Wide Area Networking (WAN)

WANs are vast networks often used to connect devices from distant geographical locations. Businesses with multiple locations often utilize WAN to connect their offices. The internet itself could be considered the largest WAN, connecting computers and networks worldwide. WANs use complex architectures and multiple types of transport systems across their vast distance, which could lead to certain vulnerability.

Metropolitan Area Networking (MAN)

MANs are larger than LANs but smaller than WANs. As the name suggests, they are designed to span the area of a city or suburb. MANs are often used by government and large enterprises to connect multiple LANs into a bigger network so they can share resources.

Personal Area Networking (PAN)

PANs can be thought of as the smallest type of networking, often connecting devices within an individual’s workspace. The best example of a PAN network might be your own suite of connected devices, such as your phone, tablet, TV, wearable tech, and laptop.

Virtual Private Networking (VPN)

A VPN is a kind of network that uses encryption to provide secure access to a remote computer over the internet. It’s often used by corporations that have a remote workforce, so employees can access secure corporate networks from the comfort of their homes.

Security Considerations in Networking

With these different types of networking comes the necessity for security. Each type of network carries its own set of vulnerabilities that may possibly be exploited by malicious actors. Hence, there is always an ongoing quest for the highest point of security possible in any system.

In recent years, the integration of IT security and networking has become an undeniable necessity. This is where cisco umbrella endpoint protection comes into play. It provides robust security measures aimed at securing all endpoints connected to a network. The ‘cisco umbrella endpoint protection’ even extends its protection over clients connected through VPNs, thereby ensuring that data transfers remain secure and reliable. Protection against malware, secure web gateways, firewall protection are features of this endpoint protection.

It’s important, therefore, to make the best choice for your needs when considering the type of network to set up. While your selection of a network will primarily hinge on your geographical layout and desired data speed, don’t forget to prioritize security. Networking and security are two sides of the same coin in today’s digital age.
