The biggest benefit of computer networks is “resource sharing”. Resource sharing is one of the main purposes for people to establish computer networks. All network users can enjoy the legal information and resources shared by others in the network; resource sharing can make full use of existing information resources and reduce the complexity of the software development process. labor and avoid repeated construction of large databases.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The application of computer networks is becoming more and more common, and its biggest benefit is that "resource sharing can be achieved."
Resource sharing is network-based resource sharing. There are many Internet enthusiasts who share their collection with everyone through some platforms without seeking profit.
Every user who accesses the Internet can enjoy the legal information and resources shared by others on the Internet. For example, we can use the Internet to carry out a series of online activities such as reading Sina Weibo, going to Taobao, and visiting JD.com. In general, The most prominent advantages are resource sharing and communication.
A computer network refers to a collection of interconnected computers that can be independent. "Interconnection" here means that two or more computers connected to each other can exchange information with each other to achieve the purpose of resource sharing. "Independent" means that each computer works independently, and no computer can interfere with the work of other computers. For example, starting, stopping, etc., there is no master-slave relationship between any two computers.
Resource sharing is one of the main purposes for people to establish computer networks. Computer resources include hardware resources, software resources and data resources. The sharing of hardware resources can improve the utilization of equipment and avoid repeated investment in equipment, such as using computer networks to establish network printers; the sharing of software resources and data resources can make full use of existing information resources, reduce labor in the software development process, and avoid Repeated construction of large databases.
Content of resource sharing
Sharing of data and applications.
Print sharing Establish a print server in the LAN to provide printing services to all users on the LAN.
Mail function The mail server can provide user name-based mail forwarding, distribution, carbon copy and other services for all employees within the enterprise, and can complete convenient management, backup, and deletion on the server. , recovery, recovery and other work.
Database The database server is an important part of the enterprise LAN and can realize functions such as data sharing, redundancy reduction, centralized storage and management, maintainability and security.
Common network storage is file sharing services, which use FTP and TFTP services to enable users to conveniently and securely access resources on shared servers on workgroup computers, and ftp resources Most are free.
Resource Backup With the development of network attacks and viruses, resource backup has become an indispensable part of resource sharing. Most modern enterprises adopt real-time and efficient resource backup methods to facilitate It can protect company information to the greatest extent when the network crashes, and play the greatest role in disaster recovery.
Personal connections: including customer resources, ability resources, etc. that can be applied to each other.
equipment.
Resource sharing under grid management
Resource sharing under grid management draws on the resource sharing of the Internet. The unit grid defined in grid management is like each terminal computer in the Internet. All unit grids in each area constitute a local area network, and the grids in all areas are integrated and connected together to ultimately form a network similar to the Internet. Grid management system. The biggest advantage of the Internet is information exchange and resource sharing, especially the now popular "cloud computing", which takes the resource sharing function to the extreme. The resource sharing of grid management is to promote the cooperation between government agencies in different regions and different departments. Integration and sharing of resources between governments, society, and citizens.
The subjects of resource sharing in the grid management system can be between different departments in the same region, between government departments and society and citizens in the same region, or between different departments in different regions, including household registration, City appearance, urban management, civil affairs, fire protection, stability maintenance, family planning, labor and security departments, etc. The resources shared between these entities include information, manpower, material resources, etc. The grid management system achieves the effect of sharing intelligence information and strengthening execution power by establishing an independent and unified command and supervision center above each management department, integrating and coordinating the forces of relevant departments, and jointly inspecting and handling various emergencies in the city. This avoids the waste of resources and improves management efficiency. At the same time, the supervision center also accepts online and telephone complaints from citizens, and urges relevant departments to quickly handle or make timely corrections. Obviously, the dual-axis management system of command and supervision in the grid management system plays a crucial role in resource sharing. Resource sharing is one of the biggest advantages of grid management, but information is the biggest factor affecting resource sharing. However, information is easily leaked, which involves privacy protection issues.
