Final answer:
The office is using a Wireless Local Area Network (WLAN) to connect network devices and printers without cabling, which provides a localized and flexible networking solution.
Step-by-step explanation:
An office's infrastructure that connects network devices and printers through a central access point without the use of cabling is typically using a Wireless Local Area Network (WLAN). This type of network allows devices to connect to the internet and communicate with each other over a wireless signal, typically Wi-Fi. In contrast to other network types like Storage Area Network (SAN), Wide Area Network (WAN), and Campus Area Network (CAN), a WLAN is localized and does not require physical cables to connect devices, offering flexibility and ease of installation within an office setting.
