Cisco routers run the IOS (Internetwork Operating System) primarily from flash memory. The IOS image is stored in the router's flash storage, allowing the device to boot and operate. Additionally, it can also be loaded from other sources, such as TFTP servers, for upgrades or recovery purposes.
Like Cisco routers, most Cisco switches run IOS, and can be configured in a similar way. Older non-IOS switches still use the console port to configure them, just like the routers.

A Cisco 7500 router is a chassis containing RSP blades and interface blades. The interface blades contain the actual working router ports, the RSP blades run the router IOS. At least one RSP is present per router, and each RSP has (like most Cisco routers) one console port and one auxiliary port. The other RSP, when present, acts only like a failover device.
Very much not.The 1900 series is a very old switch that does not even run a normal IOS. Its successor, the 2900XL series, does run an IOS. The 2900XL series' successor, the 2950 series, still does not support layer 3 routing. For layer 3 functions, you need Cisco 3550, 3560, or 3570 series switches.
EIGRP is a Cisco proprietary routing protocol and therefore can only be used with Cisco routers.You can do route redistribution on Cisco routers, this allows you to take routes from another routing protocol (such as OSPF or RIP) and place them into the EIGRP network that way downstream nodes can be informed of routes available.
The iPhone 5 will run iOS 6 or iOS 7.
By installing them and opening them. iOS has backward compatibility.
Yes. The iPhone 3G can run all iOS versions up to 4.2.1.
They are used to run the internet.
iOS 7 Can't run on an iPad 1. The hardware is simply not powerful enough to run the operating system. I believe iOS 5 is the newest OS that will run on the original iPad.
well an IOS is the OS that Cisco uses on their firewall, swithes and stuff like that.. I think what you mean is a ISO, which is a type of file. Most ISO files are for make CD's. You can also use a program like dameon tools to mount the file as another drive on your computer so you can run the ISO without burning it to a cd.
Yes, you can run iOS 7 on the iPhone 4.
