An "ISO router" is a slightly ambiguous term. It most likely refers to a router running the Cisco Internetwork Operating System (IOS).
More accurately, here's a breakdown:
-
Cisco IOS: The Internetworking Operating System (IOS) is a family of proprietary network operating systems used primarily on Cisco Systems routers and network switches. It's the software that powers most Cisco network devices and handles routing, switching, and other network functions.
-
Router: A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. A router is connected to at least two networks, typically two LANs or WANs or a LAN and its ISP's network.
Therefore, if someone refers to an "ISO router," they are likely referring to a Cisco router using the IOS software to perform routing functions. The "ISO" part is likely a misinterpretation or typo of "IOS".
It's important to note that "ISO" by itself refers to the International Organization for Standardization, which develops and publishes international standards. While ISO standards are relevant to networking and hardware, "ISO router" isn't a standard or common term.
