About this interactive
The lesson's levels, from simple to complex:
- **Consumer:** personal use, such as a phone or a home internet connection, much of it entertainment. Less expensive and less reliable.
- **SOHO (small office, home office):** someone working from home, or a small storefront. Small needs and its own kind of equipment.
- **Small and medium-sized business (SMB):** more people rely on the network, with different technology needs from an enterprise.
- **Enterprise:** the big businesses, with enterprise-level packages, topologies and services.
The lesson gives no head counts. The cards keep clear of the borders: a SOHO is one or a few people, an SMB tens to a few hundred staff, an enterprise thousands.
