The present paper designed and realizes the experiment to use equipment's three dimensional three-dimensional demonstration and to introduce that has constructed the local area network or the large-scale network visit demonstration,the plan network application environment experiment,the router disposition experiment,DHCP,the DNS server's disposition experiment and so on "Computer network" the curriculum several model experiment,these experiments might step the platform use,therefore it has made up the traditional practice teaching insufficiency,had certain use value希望楼主满意 The present paper designed and realizes the experiment to use equipment's three dimensional three-dimensional demonstration and to introduce that has constructed the local area network or the large-scale network visit demonstration,the plan network application environment experiment,the router disposition experiment,DHCP,the DNS server's disposition experiment and so on "Computer network" the curriculum several model experiment,these experiments might step the platform use,therefore it has made up the traditional practice teaching insufficiency,had certain use value希望楼主满意
