Vim li cas koj xav tau ib tug kev tswj hloov

Lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub computer tes hauj lwm yog mus cuag txawv pab kiag li lawm (tus kheej computers, peripheral pab kiag li lawm) nyob rau hauv ib qhov system uas cia li ob hardware Cheebtsam: routers thiab keyboards. Los ntawm xws li, tag nrho cov network ntsiab yuav nrog txhua lwm yam thiab nrog rau lwm yam tes hauj lwm. Externally, cov keyboards thiab routers saib zoo sib xws, tiam sis lawv muaj txawv zog. Nyob rau hauv no tsab xov xwm peb yuav tsom ntsoov rau cov thawj ntaus ntawv, thiab nyob rau tej cais lawv daim ntawv raws li ib tug tswj mus. Yog li ntawd, zoo li cas ntawm cov khoom?

Lub hom phiaj thiab cov hom ntawm keyboards

Cov pab kiag li lawm yog siv los tsim tes hauj lwm nyob rau hauv ib zaug xwb lub tsev los yog ib cheeb tsam. Cov keyboards txuas PCs, servers, printers, scanners, li no tsim ib tug sib pab network. Xws li tau khiav lag luam raws li ib tug xws li, uas yog cia kom cov ntau yam ntsiab los muab kev nkag tau rau cov lus qhia, thiab koom tau nrog lwm cov neeg tuaj koom. Los ntawm kev ntawm tej ntaub ntawv thiab muab faib rau cov kev pab, txhim kho qhov kev kawm ntawm cov keyboards ntawm lub network.

Nws muaj ob hom ntawm xws li: kev tswj thiab unmanaged. Tsis ntev los no ua hauj lwm nyob rau hauv tus txheej txheem template. Tus neeg siv yuav tsis hloov nyob rau hauv nws. Nyob rau hauv lub tsev tes hauj lwm txiav txim siab los siv no hom. Managed Hloov tso cai nkag tau mus rau lub cajmeem. Vim li no cov zoo, nws kom siab yooj ntawm lub system. Qhov no yog vim lub fact tias ib tug tswj hloov yuav configured thiab saib xyuas remotely los yog zos rau cov kev tswj ntawm network tsheb thiab nkag mus rau nws. Cia peb xav txog nyob rau hauv ntau yam no hom ntawm pab kiag li lawm.

Hloov tswj: kev nta

Xws li muaj peev xwm txhawb ntau yam sib txawv nta kom hloov mus rau tus ntaus ntawv chaw. Cov neeg teb xov tooj yuav xa mus rau lub ntaus ntawv ib cantilever lead thiab siv CLI rau configure cov kev ua ntawm lub ntaus ntawv. Nyob rau hauv tas li ntawd, tus ntaus ntawv yuav tshuaj ntawm SNMP, Telnet, SSL thiab SSH. Ib tug tswj hloov peev xwm txhawb advanced nta (RSTP, MSTP, STP), yog hais tias tus network (nruab nrab ntawm lub pab kiag li lawm thiab computers) muaj ob los yog ntau tshaj lwm txoj kev. Yog hais tias tus neeg siv yuav tsum tau mus pab rau cov theem ntawm network kev ruaj ntseg, koj yuav teev ib tug tshwj xeeb muaj nuj nqi 802,1 X, ACL. Managed hloov hom, nyob ntawm seb qhov hauj lwm, yog muaj peev xwm txhawb ntau yam VLAN. Xws li tej zaum yuav muab siab ntseeg thiab stability ntawm computer tes hauj lwm.

xaus

Txoj kev loj hlob yog tsis nyob rau hauv qhov chaw network khoom. Nyob rau hauv qhov kev lag luam, muaj ib txwm tshiab kiag li lawm. Ib txhia ntawm lawv yog tsim los tsim computer tes hauj lwm uas siv cov tooj liab cables, thaum lwm tus neeg - rau rau lub hauv paus ntawm fiber-optic technology tes hauj lwm. Ib yam li ntawd, sai heev thiab peb tau sib tham txog lub ntaus ntawv. Piv txwv li, koj yuav saib tau lub computer network, uas tswj cov tshuaj hloov theem 2 los yog 3 theem. Lub koob meej ntawm tej khoom siv yog vim lub thoob plaws computerization, vim hais tias tam sim no ua ke rau hauv ib lub cev thiab telephony, thiab TV, thiab hauv internet, thiab txawm ib tug bank network.
