LAN 區域網絡設計

A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building). Usually, the server has applications and data storage that are shared in common by multiple computer users. A local area network may serve as few as two or three users (for example, in a home network) or many as thousands of users (for example, in an FDDI network).

Wireless networks save small businesses time and money. They install easily, expand quickly and reduce the costs of planning for and implementing a wired network. This makes dynamic moves, additions and changes easy to implement. Small businesses located in older buildings find that wireless LANs are a cost-efective, network infrastructure solution. Small businesses can set up a freestanding all-wireless network or they can integrate wireless LANs to extend an existing LAN.
