What was the world's first true microcomputer LAN operating system?

The world's first true microcomputer LAN operating system is NetWare; NetWare is a network operating system launched by NOVELL. Its most important feature is an open system structure based on basic module design ideas. Microcomputer LAN structure Generally, the LAN operating system is used. The emergence of NetWare ends the development history of microcomputer network systems using the single-task operating system DOS as the core.

What is the world’s first true microcomputer LAN operating system?

The world’s first true microcomputer LAN operating system is NetWare.

Microcomputer LAN structures generally use LAN operating systems, such as NetWare, the first true microcomputer LAN operating system.

In 1984, with the official appearance of version 1.0 of NetWare developed by Novell, it ended the development history of microcomputer network systems using the single-task operating system DOS as the core, marking a new breakthrough in microcomputer LAN operating system products. Novell network has become the mainstream product of local area network.

The most important feature of Netware is the open system structure based on the basic module design idea. Netware is an open network server platform that can be easily expanded.

Netware is a network operating system launched by NOVELL. The most important feature of Netware is the open system structure based on basic module design ideas. Netware is an open network server platform that can be easily expanded. The Netware system provides consistent services for different work platforms (such as DOS, OS/2, Macintosh, etc.), different network protocol environments such as TCP/IP, and various workstation operating systems. You can add optional extended services (such as backup backup, database, email, accounting, etc.) to the system. These services can be obtained from Netware itself or from third-party developers.

Introduction to system components

The NetWare operating system is centered on the file server and mainly consists of three parts: the file server core, the workstation shell, and the low-level communication protocol.

The file server kernel implements NetWare's core protocol (NetWare Core Protocol, NCP) and provides NetWare's core services. The file server kernel is responsible for processing network workstation service requests and completing the following network services and management tasks:

• Kernel Process Service

• File System Management

• Security and Confidentiality Management

• Hard Disk Management

• System Fault Tolerance Management

• Connection management of servers and workstations

• Network monitoring

Introduction to common protocols

• IPX

Internet Network Packet Exchange protocol. Layer 3 routing and network protocols. When a device establishes a communication connection with a local machine on a different network, IPX sends information to the destination through any intermediate networks. IPX is similar to the IP protocol in the TCP/IP suite of protocols.

• SPX

Sequenced Packet Exchange protocol. Transport layer (Layer 4) control protocol that provides reliable, connection-oriented datagram transmission services. SPX is similar to the TCP protocol in the TCP/IP protocol suite.

• NCP

Network Core Protocol is a set of server specifications mainly used to implement applications such as those from NetWare Workstation Shell (NetWare shell) application requests. Services provided by NCP include file access, printer access, name management, accounting, security, and file synchronization.

• NetBIOS

Network Basic Input/Output System (NetBIOS: Network Basic Input/Output System), provided by IBM and Microsoft session layer interface specification. NetBIOS emulation software launched by NetWare Corporation supports running programs written to the industry-standard NetBIOS interface on NetWare systems.
