Router CPU and OS





In this article we will discuss Router CPU and OS, will make brief discussion on Router CPU and OS. In last article we discuss about A Router is a Computer.




Router CPU and OS

The same thing the CPU in a PC does, it runs the OS (yes the router has an OS) and does the processing. Like all computers, tablets, gaming consoles, and smart devices, Cisco devices require a CPU to execute OS instructions, such as system initialization, routing functions, and switching functions. Allows the router to track the packets from the internet and like a traffic cop says what packet goes to what address and when for all nodes on the network.



The highlighted component in the figure is the CPU of a Cisco 1941 router with the heatsink attached. The heatsink helps dissipate the heat generated by the CPU. Paying more for a faster processor doesn’t make any sense unless you have a specific need.

The CPU requires an OS to provide routing and switching functions. The Cisco Internetwork Operating System (IOS) is the system software used for most Cisco devices regardless of the size and type of the device. It is used for routers, LAN switches, small wireless access points, large routers with dozens of interfaces, and many other devices.
