Computer networking, explained in short videos
Explore a curated directory of 22 concise explainers covering how networks are organized, how far they reach, and how devices communicate. Start with familiar networks like Wi-Fi and mobile, then move into campus, enterprise, storage, mesh, and other specialized systems.
This collection brings together short, topic-focused videos for students, teachers, and anyone getting to grips with networking. The lessons move from networks defined by physical scale—such as a personal area network (PAN), local area network (LAN), metropolitan area network (MAN), and wide area network (WAN)—to systems defined by purpose or structure, including storage area networks, peer-to-peer networks, and software-defined networks.
Use the tags to narrow the directory, or watch from top to bottom for a broad introduction. The videos explain standard networking concepts; this collection is an educational index, not a claim of ownership over the underlying technologies.
Editorial note: Descriptions below summarize the scope of each explainer. The directory includes 22 videos totaling 46 minutes and 12 seconds; it does not provide audience-view counts or a popularity ranking.
Types of computer networks are ways to classify connected devices by their coverage area, purpose, or communication structure. A PAN links nearby personal devices, a LAN serves a limited local area, and a WAN connects networks over long distances; other categories describe specialized uses or ways that devices share data. Learning the distinctions helps people understand what a network is built to connect and how information moves through it.

Concept and prompt fidelity
Keep the core distinction accurate—for example, local coverage versus long-distance connectivity—and make each visual serve that learning goal.
Visual sequencing and style
Show the path a message takes in a clear sequence, then maintain a consistent visual language across related lessons.
Motion and rendering clarity
Use motion to clarify packet flow, network reach, or device relationships rather than adding movement that competes with the explanation.

There are 22 distinct videos in this directory, grouped into network fundamentals, wireless and specialized networks, and architecture and data-sharing topics. Together, their stated durations add up to 46 minutes and 12 seconds. Use the tags to narrow the collection to a particular scale, technology, or networking concept.
The phrase refers to ways of classifying networks by coverage area, purpose, or architecture. PAN, LAN, MAN, and WAN describe common scales, while labels such as SAN, P2P, mesh, and SDN describe specialized functions or structures. These categories can overlap, so they are best understood as different ways to describe how devices connect and share information.
The videos cover several kinds of geographic scale, including campus, metropolitan, wide area, and global networks. The internet is identified in the collection as the best-known example of a WAN and as an example of a GAN. No view counts or audience measurements were provided, so the directory cannot identify a most-watched video or rank network types by popularity.
A LAN connects devices in a limited local area, such as a home, office, or school building. A WAN connects local networks across longer distances using infrastructure such as cables, mobile networks, or satellites. A LAN may be part of a WAN, and a local network can sometimes continue functioning even if its internet connection is unavailable.
