A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.. Historically operating systems with networking capabilities were described as network operating systems, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN).
An Ethernet adapter card for the IBM PC was released in 1982, and, by 1985, 3Com had sold 100,000. [16] In the 1980s, IBM's own PC Network product competed with Ethernet for the PC, and through the 1980s, LAN hardware, in general, was not common on PCs. However, in the mid to late 1980s, PC networking did become popular in offices and schools ...
A network interface controller (NIC, also known as a network interface card, [3] network adapter, LAN adapter and physical network interface [4]) is a computer hardware component that connects a computer to a computer network. [5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
Network operating systems (NOSs) are operating systems that provide support for computer networking in addition to traditional hardware support. These were an important sub-class of conventional operating systems from the 1980s into the 1990s during the introduction of the early local area network (LAN) systems. As personal computers grew in ...
Junos operating system is primarily based on FreeBSD on bare metal and later also with Linux kernel. [8] Because FreeBSD is a Unix implementation, users can access a Unix shell and execute normal Unix commands. Junos runs on most or all Juniper hardware systems. [9]
In the late 1980s, Novell was looking to shed its hardware server business and transform its flagship NetWare product into a PC-based server operating system that was agnostic and independent of the physical network implementation and topology (Novell even referred to NetWare as a NOS, or network operating system). To do this, Novell needed ...
NX-OS is a network operating system for the Nexus-series Ethernet switches and MDS-series Fibre Channel storage area network switches made by Cisco Systems. [1] It evolved from the Cisco operating system SAN-OS, originally developed for its MDS switches. Cisco is responsible for its development and maintenance. [1]
MS partnered with 3Com to produce the more widely used 3+Share system running on a 3Com networking stack based on the XNS protocol on Ethernet. Other well-known systems, including Banyan VINES and Novell NetWare, did not use MS-Net as their basis, using Unix and a custom OS, respectively. They did, however, allow access to their own files via ...
