The early version of IOS is an independent system, which is basically router-centric. It is arranged as a set of procedures, allowing any procedure to call each other. This single structure reduces the concealment and independence of data. Most of its opcodes have the correlation between structure and operation.
IOS provides the most extensive standards-based physical and logical protocol interfaces-more than any other provider in the industry: from twisted pair to optical fiber, from local area network to campus network to wide area network, Novell NetWare, UNIX, SNA and many other interfaces.
