| Explanation:Small businesses today do need Internet access and use an Internet router to provide this need. A switch is required to connect the two host devices and any IP phones or network devices such as a printer or a scanner. The switch may be integrated into the router. A firewall is needed to protect the business computing assets. Redundancy is not normally found in very small companies, but slightly larger small companies might use port density redundancy or have redundant Internet providers/links. |
