Novell NetWare was one of the first true network operating systems. Its multi-user and multi-tasking architecture enables the system to handle different workstation requirements simultaneously and to support several different operating systems. This is in complete contrast to network operating systems that have since disappeared from the market, which ran on the server practically as an application under the DOS operating system and could thus also process only one request per time unit, such as the IBM PC LAN program or 3+ from 3Com.
Novell was the first company to bring multitasking to the server, long before OS/2 and Unix. Novell offers from the entry-level NetWare Lite for 2 to 25 users to the core versions Netware 2.2 for around 100 users per server, NetWare 3.1 for up to 1000 users per server and Netware 4.0 with practically unlimited number of users and global naming and logical server coupling up to versions of NetWare under other operating systems (Unix, Virtual Memory System (VMS) etc.) a broad spectrum, which is supplemented by a multiplicity of infrastructure, auxiliary and coupling programs from host coupling up to network management.transmission speeds, cables, distances, security levels and expansion options. NetWare supports five interfaces for network and application software to date.
Three of these are special NetWare interfaces: the Internetwork Packet ExchangeProtocol (IPX) is at layer 3 and allows addressing directly from the application, and the Sequenced Packet Exchange Protocol (SPX) is at the transport layer of the OSI reference model. SPX provides mechanisms that verify error-free communication. The NetWare shell corresponds to the presentation layer of the OSI reference model and is an extension of the functions available under DOS, for example.workstations on the Novell network to end systems that use TCP/IP protocols for communication, and vice versa, access from TCP/IP workstations to Novell servers. The NetWare versions 5. 0 and 5.1 also support Apple systems without problems and comfortably.
In version 6, NetWare presents itself as a Web platform that offers modern technologies in e-business. In addition, NetWare 6 supports the connection between Windows, Unix, Linux and Web-based clients with the NetWare servers. NetWare 6 lives up to the "One Net" claim in that it connects storage environments with high availability and scalability across diverse networks. Clustering technology, which serves to protect resources, software and hardware, ensures high availability of data stocks. Various security and authentication functions are implemented in NetWare 6. resources are protected by the NetWare Directory Service (NDS). NetWare 6 also meets the demand for access to all network services from a wide variety of mobile and stationary end devices.NetWare 6.5 version offers several additional services. For example the open source database MySQL, the web serverApache 2.0 and the Novell Extended Application Server. To the web server there are the well-known script languages like Perl 5.8 or PHP 4.2.3. The communication in intranets is supported by the software for group workstations.
