Networks are classified based on their size and the area they cover. For example, a personal area network connects devices like phones and headphones within a very short range, usually for personal use. A local area network (LAN) links computers in a small area like a home, office or school to share files, printers or even internet access. We can all agree that many of us are familiar with this type of classifications as it applies mostly to gamers. Metropolitan area networks another classification in which covers a large area such as a city or a campus in which connects multiple LANS together. Lastly, a wide area network (WAN) spans huge distances, connecting computers and smaller networks across cities, or even countries, the internet being the most common example. Each type serves the purpose of enabling communication and resources sharing, suited to it’s scale. Understanding these are important because they help us understand how to best connect and manage devices based on distance, scale and purpose. Classifying networks helps us design systems that are both practical and efficient.
