Proteon, Inc. was a pioneering designer and manufacturer of computer network equipment based in Westborough, Massachusetts . Proteon created the first commercial Token Ring products and created the first commercially available multiprotocol Internet router as well as the OSPF routing protocol.
69-441: Proteon designed and manufactured of some of the earliest commercial local area network and TCP/IP Internet Router products. Although founded in 1972 by Howard Salwen as communications consulting firm, Proteon became a manufacturer when they produced the first commercial Token Ring network interfaces and media access units in conjunction with MIT . In 1981, they released the 10 Mbit/sec Pronet-10 Token Ring network. and evolved
138-455: A CP/M disk sharing system to help network the Motorola 68000-based hardware that Novell sold at the time. The first S-Net is CP/M-68K -based and shares a hard disk. In 1983, the team was privately convinced that CP/M was a doomed platform and instead came up with a successful file-sharing system for the newly introduced IBM-compatible PC . They also wrote an application called Snipes –
207-445: A hotspot service. Network topology describes the layout of interconnections between devices and network segments. At the data link layer and physical layer , a wide variety of LAN topologies have been used, including ring , bus , mesh and star . Simple LANs generally consist of cabling and one or more switches . A switch can be connected to a router , cable modem , or ADSL modem for Internet access. A LAN can include
276-747: A local drive letter to a NetWare volume. Clients log into a server in order to be allowed to map volumes, and access can be restricted according to the login name. Similarly, they can connect to shared printers on the dedicated print server , and print as if the printer is connected locally. At the end of the 1990s, with Internet connectivity booming, the Internet's TCP/IP protocol became dominant on LANs . Novell had introduced limited TCP/IP support in NetWare 3. x ( c. 1992 ) and 4. x ( c. 1995 ), consisting mainly of FTP services and UNIX-style LPR/LPD printing (available in NetWare 3. x ), and
345-421: A wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits . Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET , Token Ring and AppleTalk . The increasing demand and usage of computers in universities and research labs in the late 1960s generated
414-467: A wide area network (WAN). Novell NetWare NetWare is a discontinued computer network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various services on a personal computer, using the IPX network protocol. The original NetWare product in 1983 supported clients running both CP/M and MS-DOS , ran over a proprietary star network topology and
483-600: A DOS or Windows driver allowing companies to consolidate modems and analog phone lines. Promised as early as 1988, when the Microsoft-IBM collaboration was still ongoing and OS/2 1. x was still a 16-bit product, the product didn't become commercially available until after IBM and Microsoft had parted ways and OS/2 2.0 had become a 32-bit, pre-emptive multitasking and multithreading OS. By August 1993, Novell released its first version of "NetWare for OS/2". This first release supported OS/2 2.1 (1993) as
552-563: A Novell-developed webserver (in NetWare 4. x ). Native TCP/IP support for the client file and print services normally associated with NetWare was introduced in NetWare 5.0 (released in 1998). There was also a short-lived product, NWIP, that encapsulated IPX in TCP/IP, intended to ease transition of an existing NetWare environment from IPX to IP. During the early to mid-1980s Microsoft introduced their own LAN system in LAN Manager , based on
621-470: A Support Pack for NetWare 6.5. As Novell initially used IPX/SPX instead of TCP/IP , they were poorly positioned to take advantage of the Internet in 1995. This resulted in Novell servers being bypassed for routing and Internet access in favor of hardware routers, Unix -based operating systems such as FreeBSD , and SOCKS and HTTP Proxy Servers on Windows and other operating systems. A decision by
690-462: A dedicated PC to act as the server, where the server uses DOS only as a boot loader to execute the operating system file NET$ OS.EXE . All memory is allocated to NetWare; no DOS ran on the server. However, a "non-dedicated" version was also available for price-conscious customers. In this, DOS 3.3 or higher remains in memory, and the processor time-slices between the DOS and NetWare programs, allowing
759-426: A higher 16 MiB RAM limit, 80286 processor feature utilization, and 256 MB NetWare volume size limit (compared to the 32 MB that DOS allowed at that time) allowed the building of reliable, cost-effective server-based local area networks for the first time. The 16 MiB RAM limit was especially important, since it makes enough RAM available for disk caching to significantly improve performance. This became

#1732779628545828-565: A license model giving them essentially unlimited per-server users if they let Novell audit their total user count.) Version 4 also introduced a number of useful tools and features, such as transparent compression at file system level and RSA public/private encryption . Another new feature was the NetWare Asynchronous Services Interface (NASI). It allowed network sharing of multiple serial devices, such as modems . Client port redirection occurred via
897-526: A logical server to be completely mirrored to a separate physical machine. Implemented as a shared-nothing cluster, under SFT-III the OS was logically split into an interrupt-driven I/O engine and the event-driven OS core. The I/O engines serialized their interrupts (disk, network etc.) into a combined event stream that was fed to two identical copies of the system engine through a fast (typically 100 Mbit/s) inter-server link. Because of its non-preemptive nature,
966-418: A mixture of technologies such as ARCNET , Token Ring and Ethernet . The operating system is provided as a set of compiled object modules that required configuration and linking. Any change to the operating system requires a re-linking of the kernel . Installation also requires the use of a proprietary low-level format program for MFM hard drives called COMPSURF. The file system used by NetWare 2. x
1035-489: A much more sophisticated operating system than most of its competitors. Of the competitors to NetWare, only Banyan Vines had comparable technical strengths, but Banyan never gained a secure base. 3Com produced 3+Share and Microsoft produced MS-Net . These then formed the basis for collaboration between Microsoft and 3Com to create a simple network operating system LAN Manager and its cousin, IBM's LAN Server . None of these enjoyed any lasting success; Netware dominated
1104-582: A package containing a compatibility guideline book, engineering support lines, self-testing tools, and limited marketing resources, the latter including a license to promote products with a logo stating "Yes, it runs with NetWare" – all free of charge and followed at the vendors' discretion. The second tier required a one-time application fee of $ 7,000 but replaced the logo's byline with a more confident-sounding "Yes, it's NetWare tested and approved" and accorded partners with more extensive support, including on-location testing by Novell Labs. Initially limited to
1173-586: A star network topology . This was later joined by NetWare 86 , which could use conventional Intel 8086-based PCs for the server. This was replaced in 1985 with Advanced NetWare 86, which allowed more than one server on the same network. In 1986, after the Intel 80286 processor became available, Novell released Advanced NetWare 286. Two versions were offered for sale; the basic version was sold as ELS I, plus an enhanced version, ELS II. *ELS* stood for "Entry Level System". Advanced NetWare version 2. x , launched in 1986,
1242-403: A text-mode game – and used it to test the new network and demonstrate its capabilities. Snipes [aka 'NSnipes' for 'Network Snipes'] is the first network application ever written for a commercial personal computer, and it is recognized as one of the precursors of many popular multiplayer games such as Doom and Quake . First called ShareNet or S-Net , this network operating system (NOS)
1311-566: A third-party client. NetWare originated from consulting work by SuperSet Software , a group founded by the friends Drew Major , Dale Neibaur, Kyle Powell and later Mark Hurst. This work stemmed from their classwork at Brigham Young University in Provo, Utah , starting in October 1981. In 1981, Raymond Noorda engaged the work by the SuperSet team. The team was originally assigned to create
1380-495: A wide variety of other network devices such as firewalls , load balancers , and network intrusion detection . Advanced LANs are characterized by their use of redundant links with switches using the spanning tree protocol to prevent loops, their ability to manage differing traffic types via quality of service (QoS), and their ability to segregate traffic with VLANs . At the higher network layers, protocols such as NetBIOS , IPX/SPX , AppleTalk and others were once common, but
1449-399: Is NetWare File System 286, or NWFS 286, supporting volumes of up to 256 MB. NetWare 286 recognizes 80286 protected mode , extending NetWare's support of RAM from 1 MiB to the full 16 MiB addressable by the 80286. A minimum of 2 MiB is required to start up the operating system; any additional RAM is used for FAT , DET and file caching. Since 16-bit protected mode

#17327796285451518-471: Is accomplished using the keyboard interrupt , which requires strict compliance with the IBM PC design model, otherwise performance is affected. Server licensing on early versions of NetWare 286 is accomplished by using a key card. The key card was designed for an 8-bit ISA bus, and has a serial number encoded on a ROM chip. The serial number has to match the serial number of the NetWare software running on
1587-460: Is implemented in the 80286 and every subsequent Intel x86 processor, NetWare 286 version 2. x will run on any 80286 or later compatible processor. NetWare 2. x implements a number of features inspired by mainframe and minicomputer systems that were not available in other operating systems of the day. The System Fault Tolerance (SFT) features includes standard read-after-write verification (SFT-I) with on-the-fly bad block re-mapping (at

In a wireless LAN , users have unrestricted movement within the coverage area. Wireless networks have become popular in residences and small businesses, because of their ease of installation. Most wireless LANs use Wi-Fi as wireless adapters are typically integrated into smartphones , tablet computers and laptops . Guests are often offered Internet access via
1725-470: The CP/M operating system in the late 1970s, and later DOS -based systems starting in 1981, meant that many sites grew to dozens or even hundreds of computers. The initial driving force for networking was to share storage and printers , both of which were expensive at the time. There was much enthusiasm for the concept, and for several years, from about 1983 onward, computer industry pundits habitually declared
1794-459: The Internet protocol suite (TCP/IP) has prevailed as the standard of choice. LANs can maintain connections with other LANs via leased lines, leased services, or across the Internet using virtual private network technologies. Depending on how the connections are established and secured, and the distance involved, such linked LANs may also be classified as a metropolitan area network (MAN) or

A version designed for networks of 25 or fewer users was named IntranetWare for Small Business and contained a limited version of NDS and tried to simplify NDS administration. The intranetWare name was dropped in NetWare ;5. During this time Novell also began to leverage its directory service, NDS, by tying their other products into
1932-466: The 1980s, several token ring network implementations for LANs were developed. IBM released their own implementation of token ring in 1985, It ran at 4 Mbit/s . IBM claimed that their token ring systems were superior to Ethernet, especially under load, but these claims were debated. IBM's implementation of token ring was the basis of the IEEE 802.5 standard. A 16 Mbit/s version of Token Ring
2001-573: The Bindery with a global directory service , in which the infrastructure was described and managed in a single place. Additionally, NDS provided an extensible schema , allowing the introduction of new object types. This allowed a single user authentication to NDS to govern access to any server in the directory tree structure. Users could therefore access network resources no matter on which server they resided, although user license counts were still tied to individual servers. (Large enterprises could opt for
2070-480: The OS core, stripped of non-deterministic I/O, behaves deterministically, like a large finite state machine . The outputs of the two system engines were compared to ensure proper operation, and two copies fed back to the I/O engines. Using the existing SFT-II software RAID functionality present in the core, disks could be mirrored between the two machines without special hardware. The two machines could be separated as far as
2139-645: The United States, this program was rolled out in the United Kingdom in the following year. For a while, Novell also marketed an OEM version of NetWare 3, called Portable NetWare . Originally announced in 1989 by Prime Computer as a product for its Prime EXL range, along with a distinct product for Unix System V, Novell attracted support from a number of other OEMs including Data General , Hewlett-Packard , NCR Corporation , Sun Microsystems and Unisys . An implementation provided by Altos

2208-505: The Windows graphical interface to learning DOS commands necessary to build and control a NetWare server. Novell could have eliminated at least the separately bootable DOS partition requirement at the outset, by retaining the design of NetWare 286, which installed the server file into a Novell partition and allowed the server to boot from the Novell partition without creating a bootable DOS partition. Novell finally added support for this in
2277-478: The arrival of Windows NT Server, Novell claimed 90% of the market for PC based servers. However, the design of NetWare 3. x and later involved a DOS partition to load NetWare server files. While of little technical import, this feature became a liability due to the system administration it required. Compounding this, the NetWare console remained text-based at a time the Windows graphical interface gained widespread acceptance. Especially new users preferred
2346-525: The base OS, and required that users first buy and install IBM OS/2, then purchase NetWare 4.01, and then install the NetWare for OS/2 product. It retailed for $ 200. By around 1995, and coincidental with IBM's renewed marketing push for its 32-bit OS/2 Warp OS, both as a desktop client and as a LAN server (OS/2 Warp Server), NetWare for OS/2 began receiving some good press coverage. "NetWare 4.1 for OS/2" allowed to run Novell's network stack and server modules on top of IBM's 32-bit kernel and network stack. It
2415-672: The benches of the European Parliament Hemicycles in Strasbourg and Luxembourg. Early Ethernet ( 10BASE-5 and 10BASE-2 ) used coaxial cable . Shielded twisted pair was used in IBM's Token Ring LAN implementation. In 1984, StarLAN showed the potential of simple unshielded twisted pair by using category 3 cable —the same cable used for telephone systems. This led to the development of 10BASE-T (and its twisted-pair successors ) and structured cabling which
2484-533: The coming year to be, "The year of the LAN". In practice, the concept was marred by the proliferation of incompatible physical layer and network protocol implementations, and a plethora of methods of sharing resources. Typically, each vendor would have its own type of network card, cabling, protocol, and network operating system . A solution appeared with the advent of Novell NetWare which provided even-handed support for dozens of competing card and cable types, and
2553-453: The competing NBF protocol. Early attempts to compete with NetWare failed, but this changed with the inclusion of improved networking support in Windows for Workgroups , and then the successful Windows NT and Windows 95 . NT, in particular, offered a sub-set of NetWare's services, but on a system that could also be used on a desktop, and due to the vertical integration there was no need for
2622-437: The directory. Their e-mail system, GroupWise , was integrated with NDS, and Novell released many other directory-enabled products such as ZENworks and BorderManager . NetWare still required IPX/SPX as NCP used it, but Novell started to acknowledge the demand for TCP/IP with NetWare 4.11 by including tools and utilities that made it easier to create intranets and link networks to the Internet. Novell bundled tools, such as
2691-480: The feasibility of employing TCP/IP LANs to interconnect Worldwide Military Command and Control System (WWMCCS) computers at command centers throughout the United States. However, WWMCCS was superseded by the Global Command and Control System (GCCS) before that could happen. During the same period, Unix workstations were using TCP/IP networking. Although the workstation market segment is now much reduced,
2760-458: The first versions of NetWare originated, all other competing products were based on the concept of providing shared direct disk access. Novell's alternative approach was validated by IBM in 1984, which helped promote the NetWare product. Novell NetWare shares disk space in the form of NetWare volumes , comparable to logical volumes . Client workstations running DOS run a special terminate and stay resident (TSR) program that allows them to map
2829-544: The key to Novell's performance while also allowing larger networks to be built. In a significant innovation, NetWare 286 is also hardware-independent, unlike competing network server systems. Novell servers can be assembled using any brand system with an Intel 80286 CPU, any MFM , RLL , ESDI , or SCSI hard drive and any 8- or 16-bit network adapter for which NetWare drivers are available – and 18 different manufacturer's network cards were supported at launch. The server could support up to four network cards, and these can be

2898-434: The main NetWare product line took a dramatic turn when version 4 introduced NetWare Directory Services (NDS, later renamed eDirectory ), a global directory service based on ISO X.500 concepts (six years later, Microsoft released Active Directory ). The directory service, along with a new e-mail system ( GroupWise ), application configuration suite ( ZENworks ), and security product ( BorderManager ) were all targeted at
2967-458: The management of Novell also took away the ability of independent resellers and engineers to recommend and sell the product. The reduction of their effective sales force created this downward spiral in sales. Novell priced NetWare 4.10 similarly to NetWare 3.12, allowing customers who resisted NDS (typically small businesses) to try it at no cost. Later Novell released NetWare version 4.11 in 1996 which included many enhancements that made
3036-545: The need to provide high-speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation. A number of experimental and early commercial LAN technologies were developed in the 1970s. Ethernet was developed at Xerox PARC between 1973 and 1974. Cambridge Ring was developed at Cambridge University starting in 1974. ARCNET
3105-500: The needs of large enterprises. By 2000, however, Microsoft was taking more of Novell's customer base and Novell increasingly looked to a future based on a Linux kernel . The successor to NetWare, Open Enterprise Server (OES), released in March 2005, offers all the services previously hosted by NetWare 6.5, but on a SUSE Linux Enterprise Server ; the NetWare kernel remained an option until OES 11 in late 2011. The final update release
3174-706: The operating system easier to install, easier to operate, faster, and more stable. It also included the first full 32-bit client for Microsoft Windows -based workstations, SMP support and the NetWare Administrator (NWADMIN or NWADMN32), a GUI-based administration tool for NetWare. Previous administration tools used the Cworthy interface, the character-based GUI tools such as SYSCON and PCONSOLE with blue text-based background. Some of these tools survive to this day, for instance MONITOR.NLM. Novell packaged NetWare 4.11 with its Web server, TCP/IP support and
3243-444: The personal computer LAN business from early after its introduction in 1983 until the mid-1990s when Microsoft introduced Windows NT . In 1983, TCP/IP was first shown capable of supporting actual defense department applications on a Defense Communication Agency LAN testbed located at Reston, Virginia. The TCP/IP-based LAN successfully supported Telnet , FTP , and a Defense Department teleconferencing application. This demonstrated
3312-455: The server computer to be used simultaneously as a network file server and as a user workstation. Because all extended memory (RAM above 1 MiB) is allocated to NetWare, DOS is limited to only 640 KiB; expanded memory managers that used the MMU of 80386 and higher processors, such as EMM386, do not work; 8086-style expanded memory on dedicated plug-in cards is possible however. Time slicing
3381-440: The server was in use and the volume was mounted, allowing a server to be expanded without interruption. In NetWare 386 3. x all NLMs ran on the server at the same level of processor memory protection , known as " ring 0 ". This provided the best possible performance, it sacrificed reliability because there was no memory protection, and furthermore NetWare 3. x used a co-operative multitasking model, meaning that an NLM
3450-758: The server-to-server link would permit. In case of a server or disk failure, the surviving server could take over client sessions transparently after a short pause since it had full state information. SFT-III was the first NetWare version able to make use of SMP hardware – the I/O engine could optionally be run on its own CPU. NetWare SFT-III, ahead of its time in several ways, was a mixed success. With NetWare 3 an improved routing protocol, NetWare Link Services Protocol , has been introduced which scales better than Routing Information Protocol and allows building large networks. Version 4 in 1993 introduced NetWare Directory Services, later re-branded as Novell Directory Services (NDS), based on X.500 , which replaced
3519-470: The server. To broaden the hardware base, particularly to machines using the IBM MCA bus, later versions of NetWare 2. x do not require the key card; serialised license floppy disks are used in place of the key cards. Licensing is normally for 100 users, but two ELS versions were also available. First a 5-user ELS in 1987, and followed by the 8-user ELS 2.12 II in 1988. NetWare's 3. x range

In 1986, Proteon released the first commercially available multi-protocol router, the p4200, based on the MIT multi-protocol router, using code developed by Noel Chiappa . Proteon's router products made them one of the key companies producing products to support the growing Internet , among rivals such as Cisco and Wellfleet Communications . Proteon went public in 1991, issuing 3.1 million shares. Proteon
3657-499: The technologies developed in the area continue to be influential on the Internet and in all forms of networking—and the TCP/IP protocol has replaced IPX , AppleTalk , NBF , and other protocols used by the early PC LANs. Econet was Acorn Computers's low-cost local area network system, intended for use by schools and small businesses. It was first developed for the Acorn Atom and Acorn System 2 / 3 / 4 computers in 1981. In

For single files, this requires only a file attribute to be set. Transactions over multiple files and controlled roll-backs are possible by programming to the TTS API . NetWare 286 2. x normally requires
3795-491: The unmodified NetWare 4. x server program think it owns all resources on a OS/2 system". It also claimed that a NetWare server running on top of OS/2 only suffered a 5% to 10% overhead over NetWare running over the bare metal hardware, while gaining OS/2's pre-emptive multitasking and object oriented GUI. Novell continued releasing bugfixes and updates to NetWare for OS/2 up to 1998. Novell's strategy with NetWare 286 2. x and 3. x proved very successful; before
3864-445: Was a major step forward. It began with version 3.0 in 1990, followed quickly by version 3.10 and 3.11 in 1991. A key feature was support for 32-bit protected mode , eliminating the 16 MiB memory limit of NetWare 286 and therefore allowing larger hard drives to be supported (since NetWare 3. x cached the entire file allocation table and directory entry table into memory for improved performance). NetWare version 3. x
3933-651: Was a relatively high-speed choice of that era, with speeds such as 100 Mbit/s. By 1994, vendors included Cisco Systems , National Semiconductor , Network Peripherals, SysKonnect (acquired by Marvell Technology Group ), and 3Com . FDDI installations have largely been replaced by Ethernet deployments. In 1979, the Electronic voting systems for the European Parliament was using 10 kilometers of simple unshielded twisted pair category 3 cable —the same cable used for telephone systems—installed inside
4002-649: Was also much simpler to install, with disk and network support provided by software modules called a NetWare Loadable Module (NLM) loaded either at start-up or when it was needed. NLMs could also add functionality such as anti-virus software, backup software, database and web servers. Support for long filenames was also provided by an NLM. A new file system was introduced by NetWare 3. x – " NetWare File System 386", or NWFS 386, which significantly extended volume capacity (1 TB, 4 GB files), and could handle up to 16 volume segments spanning multiple physical disk drives. Volume segments could be added while
4071-768: Was based on a Novell-built file server using the Motorola 68000 processor. The company soon moved away from building its own hardware, and NetWare became hardware-independent, running on any suitable Intel-based IBM PC compatible system, and able to utilize a wide range of network cards. From the beginning NetWare implemented a number of features inspired by mainframe and minicomputer systems that were not available in its competitors' products. In 1991, Novell introduced cheaper peer-to-peer networking products for DOS and Windows , unrelated to their server-centric NetWare. These are NetWare Lite 1.0 (NWL), and later Personal NetWare 1.0 (PNW) in 1993. In 1993,
4140-571: Was basically NetWare 4. x running as a service on top of OS/2. It was compatible with third party client and server utilities and NetWare Loadable Modules. Since IBM's 32-bit OS/2 included Netbios, IPX/SPX and TCP/IP support, this means that sysadmins could run all three most popular network stacks on a single box, and use the OS/2 box as a workstation too. NetWare for OS/2 shared memory on the system with OS/2 seamlessly. The book "Client Server survival Guide with OS/2" described it as " glue code that lets
4209-570: Was described in one review as "NetWare 386 for PC Unix systems", running in the standard Unix environment, utilising the native filesystem and network interfaces. Portable NetWare's primary purpose was to offer file and print sharing facilities, but a "native" port of Netware to other platforms was considered necessary to offer the broader feature set of Novell's traditional NetWare products. Alongside Hewlett-Packard, IBM collaborated with Novell to offer Portable NetWare and more comprehensive "native" ports of NetWare for its platforms. Portable NetWare
SECTION 60
#17327796285454278-632: Was developed by Datapoint Corporation in 1976 and announced in 1977. It had the first commercial installation in December 1977 at Chase Manhattan Bank in New York. In 1979, the Electronic voting systems for the European Parliament was the first installation of a LAN connecting hundreds (420) of microprocessor-controlled voting terminals to a polling/selecting central unit with a multidrop bus with Master/slave (technology) arbitration. The development and proliferation of personal computers using
4347-633: Was later called Novell NetWare. NetWare is based on the NetWare Core Protocol (NCP), which is a packet-based protocol that enables a client to send requests to and receive replies from a NetWare server. Initially, NCP was directly tied to the IPX/SPX protocol, and NetWare communicated natively using only IPX/SPX. The first product to bear the NetWare name was released in 1983. The original product, NetWare 68 (AKA S-Net ), ran on Novell's proprietary 68000-based file server hardware, and used
4416-439: Was later known as NetWare for UNIX. As a version of NetWare written in the C programming language, Novell would port functionality from its traditional product to a reference platform, leaving OEMs to port the Novell source code to run on top of their own, typically Unix, operating systems. While NetWare 3. x was current, Novell introduced its first high-availability clustering system, named NetWare SFT-III , which allowed

The combined company was rebranded as NX Networks. which was acquired by NSGDatacom in 2002, who dropped the NX Networks name in favor of Netrix. Local area network A local area network ( LAN ) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast,

NetWare continued to be administered using console-based utilities. With version 3. x , Novell increased the rigors of compatibility testing with their third-party vendors, revamping their certification program in October 1992 and unveiling a two-tier cooperating marketing program.

4623-491: Was standardized by the 802.5 working group in 1989. IBM had market dominance over Token Ring, for example, in 1990, IBM equipment was the most widely used for Token Ring networks. Fiber Distributed Data Interface (FDDI), a LAN standard, was considered an attractive campus backbone network technology in the early to mid 1990s since existing Ethernet networks only offered 10 Mbit/s data rates and Token Ring networks only offered 4 Mbit/s or 16 Mbit/s rates. Thus it
4692-506: Was version 6.5SP8 of May 2009; NetWare is no longer on Novell's product list. NetWare 6.5SP8 General Support ended in 2010; Extended Support was available until the end of 2015, and Self Support until the end of 2017. The replacement is Open Enterprise Server. NetWare evolved from a very simple concept: file sharing instead of disk sharing . By controlling access at the level of individual files, instead of entire disks, files could be locked and better access control implemented. In 1983 when
4761-458: Was written for the then-new 80286 CPU. The 80286 CPU features a new 16-bit protected mode that provides access to up to 16 MiB RAM as well as new mechanisms to aid multi-tasking. (Prior to the 80286, PC CPU servers used the Intel 8088 /8086 8 -/16-bit processors, which are limited to an address space of 1 MiB with not more than 640 KiB of directly addressable RAM.)
