Network operating systemA 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).
Internetwork Packet ExchangeNetwork protocol Internetwork Packet Exchange (IPX) is the network-layer protocol in the IPX/SPX protocol suite. IPX is derived from Xerox Network Systems' IDP. It also has the ability to act as a transport layer protocol. The IPX/SPX protocol suite was used by Novell's network operating system, NetWare, from the late 1980s through the late 1990s. An advantage of IPX was the small memory footprint of the IPX driver, which was vital for MS-DOS and Windows up to Windows 95.Cooperative multitaskingCooperative multitasking, also known as non-preemptive multitasking, is a computer multitasking technique in which the operating system never initiates a context switch from a running process to another process. Instead, in order to run multiple applications concurrently, processes voluntarily yield control periodically or when idle or logically blocked. This type of multitasking is called cooperative because all programs must cooperate for the scheduling scheme to work.Open Enterprise ServerServer operating system Linux distribution Open Enterprise ServerDeveloperOpenTextOS familyLinux (Unix-like) and NetWareWorking stateCurrentSource modelOpen source / Closed sourceLatest releaseOES 23.4 / October 2023; 3 years ago (2023-10)Marketing target Enterprise software Server Package managerRPM Package ManagerPreceded byNetWare 6.5Official websitewww.opentext.com/products/enterprise-server Open Enterprise Server (OES) is a server operating system published by OpenText.
MS-DOSMicrosoft computer operating systemOperating systemMS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its alternate branding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system).
CP/MDiscontinued family of computer operating systemsOperating systemCP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk.
Mainframe computerA mainframe computer, informally called a mainframe, maxicomputer, or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
IBM PC compatibleAn IBM PC compatible is any personal computer that is hardware- and software-compatible with the IBM Personal Computer (IBM PC) and its successors. Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC, and is capable of using interchangeable commodity hardware such as expansion cards.

NovellNovell, Inc. () was an American software and services company headquartered in Provo, Utah, that existed from 1980 until 2014. Its most significant product was the multi-platform network operating system known as NetWare. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide.
Star networkA star network is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. The star network is one of the most common computer network topologies. Network topologyThe hub and hosts, and the transmission lines between them, form a graph with the topology of a star.
Motorola 68000The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bitinstruction set, with 32-bit registers and a 16-bit internal data bus. The address bus is 24 bits wide and does not use memory segmentation, which made it easier to program for.*As an Amazon Associate I earn from qualifying purchases.
