This article will help you understand network operating system, as well as Windows, Linux, and others you've never heard of.

ForewordHi everyone, I'm Mr. Lin, this article will introduce you to network operating systems, except for Windows, Linux and others you've never heard of! TextThe concept of a network operating system

An operating system is software that is used on a computer system to manage various hardware and software resources and provide human-computer interaction. A network operating system can implement all functions of an operating system and manage and share resources on a network. The Network Operation System (NOS) is a set of software and communication protocols that enable different computers on a network to conveniently and efficiently share network resources and provide various services required by network users.

Operating system development process

Mid 1950s: The first simple batch operating system. Mid 1960s: batch processing systems enabling multiprogramming. The processor can process several programs in memory at same time, so that system's hardware resources are fully utilized. 1970s: Time-sharing operating system, representative products such as UNIX operating system. 1980s: Formation of network operating systems Computer local area networks (LANs) developed rapidly, and operating systems emerged to build network service platforms for LANs, typical systems such as NetWare. Entering 1990s: Network Operating System Excellence Microsoft released a series of server products, including Windows NT, Windows 2000 Server, and Windows Server 2003. Linux, Unix, and other operating systems

Network operating system functions Operating system functions typically include:
  • Processor control
  • Memory management
  • Device management
  • File system management
  • As well as user interface provided to user for convenience of using operating system.
  • The main tasks of network operating system:
  • Providing network services and managing network resources.
  • The interface between network user and server implements user's network-based remote access capability.
  • Detailed description of functions of network operating system:

    1. Shared Resource Management

    The network operating system must be able to efficiently manage shared resources on network, such as shared hardware such as disk arrays, printers and plotters, and shared software such as directories, files, databases, and shared system software. and can effectively coordinate users. The use of shared resources ensures security and consistency of shared data.

    2. Networking

    A computer connected to a network as a host systema, must support network communication function, that is, implement function from data link layer of network protocol stack to application layer, in order to realize error-free data between source host and target host Transmission, network operating system, as main equipment in network applications is soul of server, supports more protocols in network communication, providing higher security and availability.

    3. Network Service

    The network operating system has a built-in frequently used network server to provide many efficient network services to users. Typical web services include:

  • File transfer, access and management services.
  • DNS domain name resolution system.
  • User management service.
  • Security services.
  • Cluster support.
  • Hard Disk Sharing.
  • General Print Services.
  • 4. Network Management

    The network operating system supports network control protocol,

  • For example, SNMP Simple Network Management Protocol, etc. supports remote management and remote login to server, and can perform remote unified management of network servers throughout network.
  • For example, third-party network management software can be used to integrate and manage servers on a network, and to monitor server activity.
  • For example, creating an active directory using Windows domain concept can make it easier to manage servers in a network-wide domain.
  • Another important task of network management is security management,

  • For example, "access control" to secure access data;
  • Using "failover technology" to securely restore data in event of a system failure.
  • The network operating system can also monitor network performance, collect usage statistics, and provide essential information for network performance improvement, network maintenance, and accounting.

    5. Compatibility

    In a networked environment, different clients and hosts, regardless of which operating system is installed, can not only communicate with server, but also transparently access file system on server.

    6. Transferring vacancies

    That is, a job can be moved from one host computer to another host computer that has a lower workload or is suitable for processing job.

    Structure of network operating system

    Typically, there are two modes of building a local network: peer-to-peer network and client/server network. The client/server network operating system consists of two parts: client operating system and server operating system.

    Guest operating system features:

  • Enable users to use local resourcessy and process local commands and applications
  • Implement communication between client and server.
  • Server operating system functions:

  • Manage various resources on server and on network.
  • Implement communication between server and client
  • Providing network services and managing network security.
  • Common network operating systems

    Representative network operating systems are:

  • UNIX
  • Linux (free software derived from UNIX)
  • Netware (Novell)
  • Windows (Microsoft)
  • Windows NT server
  • Windows 2000 server
  • Windows Server 2003
  • Windows Server 2008
  • UNIX This article will help you understand network operating system, as well as Windows, Linux, and others you've never heard of.
  • From 1969 to 1970, American Telegraph and Telephone Company (AT&T) Bell Laboratories pioneered UNIX on a PDP-7 machine.
  • A network operating system based on time-sharing operating system developed by Massachusetts Institute of Technology.
  • UNIX is a time-sharing, centralized, multi-user, multi-tasking operating system that is currently most powerful, secure, and stable network operating system.
  • Linux This article will help you understand network operating system, as well as Windows, Linux, and others you've never heard of.
  • A next-generation network operating system with characteristics of UNIX operating system, developed by Linus Torvalds, a student at University of Helsinki, Finland.
  • The biggest feature of Linux is that its source code is completely open to users, and any user can modify kernel of Linux operating system to suit their needs.
  • Network software This article will help you understand network operating system, as well as Windows, Linux, and others you've never heard of.
  • This is world's first true microcomputer LAN operating system. In 1984, Novell Corporation of United States released version Netware1.0.
  • In 1990s, it dominated local area networks for industrial control, manufacturing plants, and security systems.
  • The Netware system provides consistent services across various work platforms (such as D0S, OS/2, Macintosh, etc.), various network protocol environments such as TCP/IP, and various workstation operating systems.
  • Windows series This article will help you understand network operating system, as well as Windows, Linux, and others you've never heard of.
  • Microsoft Corporation develops a network operating system with a friendly interface and simple operation.
  • Not only does it have an absolute advantage in personal operating systems, but it also has a very strong power in network operating systems.
  • The Windows network operating system is most commonly used on small to medium sized LANs, but because it places high demands on server hardware, it is typically used on low to medium sized servers.
