Zaka 20 zapitazi, dziko lapansi lakhala likugwiritsidwa ntchito ndi makompyuta osiyanasiyana. Kumvetsetsa zofunikira za momwe mautumikiwa akugwirira ntchito kumatithandiza kuphunzira momwe tingawagwiritsire ntchito bwino komanso kumawonjezera kuzindikira kwathu kusintha kwa dziko lathu. Gawo ili la mndandanda wathu wa momwe Computer Networks Work ikuyendera zipangizo - ma kompyuta omwe amagwirizana ndi intaneti ndikulankhulana wina ndi mzake.
Chomwe Chimapanga Chipangizo cha Network
Osati makompyuta onse, chida chogwiritsira ntchito, kapena chida china chimatha kulowa pa intaneti. Chipangizo choterechi chimakhala ndi zipangizo zamakono zothandizira kuti zikhale zofunikira pazinthu zina. Zida zamakono zamakono zili ndi makompyuta olankhulana ophatikizidwa pa matabwa awo.
Ma PC ena, masewera achikulire a Xbox, ndi zipangizo zina zakale sakhala ndi zipangizo zamakono zowonetsera koma zingathe kukhazikitsidwa ngati zipangizo zamakono pogwiritsa ntchito makina osokoneza makompyuta monga mawonekedwe a USB . Ma PC apamwamba kwambiri amafunika kuika makadi akuluakulu owonjezera omwe amachokera ku networkboard, yomwe imachokera ku Network Interface Card (NIC) .
Mibadwo yatsopano yamagetsi ndi zipangizo zamagetsi zimamangidwa monga zipangizo zamakono pamene mibadwo yakale sinali. Mwachitsanzo, zipangizo zapakhomo zapakhomo zinalibe zipangizo zamalumikizidwe, ndipo sizikanatha kuyanjanitsidwa ndi makina a nyumba kudzera m'mipiringi.
Potsirizira pake, mitundu ina ya zipangizo sizikuthandizira pa Intaneti. Zida zamagetsi zomwe sizinapangidwe mu network hardware kapena kulandira zowonjezera zikuphatikizapo akale Apple iPods, ma televisions ambiri, ndi ovens opuma.
Ntchito Zamagetsi pa Kompyuta Networks
Zida pa makompyuta amapanga maudindo osiyanasiyana. Maudindo awiri omwe ndi ofalitsa kwambiri ndi ma seva . Zitsanzo za makasitomala a pa intaneti ndi ma PC, mafoni ndi mapiritsi, ndi makina osindikiza . Otsatsa ambiri amapanga zokhazokha ndikudya deta yosungidwa m'maseva apakompyuta , zipangizo zambiri zomwe zimapangidwa ndi malingaliro ambiri ndi / kapena disk yosungirako komanso mapulogalamu apamwamba kuti athandizire makasitomala. Zitsanzo za ma seva a pawebusaiti ndi ma seva a pawebusaiti ndi maseva osewera. Makompyuta mwachibadwa amathandiza makasitomala ambiri kuposa antchito. Nthawi zonse makasitomala ndi ma seva amatchedwa network nodes .
Zida zamakono zingakhalenso zogwira ntchito ngati makasitomala ndi maseva. Kwa anzanu ochezera anzanu , mwachitsanzo, awiri a zipangizo amagawana mafafa kapena deta ina, wina akuchita seva akugwira ntchito zina koma nthawi yomweyo amagwira ntchito ngati kasitomala kuti apemphe deta yosiyana kuchokera kwa makina ena a anzawo.
Cholinga cha Special Purpose Network
Ma client ndi ma seva angathe kuwonjezedwa kapena kuchotsedwa pa intaneti popanda kuletsa kuyankhulana kwa zipangizo zina zomwe zatsala. Mitundu ina yamakina a hardware, komabe, ilipo cholinga chokha chokhazikitsa ma intaneti:
- Kachipangizo kameneka kamathandiza kuti mfundo iliyonse ikhale yogwirizana nayo kuti itumize mwachindunji deta kwa ena
- Zosintha zamagetsi zimagwira ntchito yomweyo monga hubs koma zimakhala ndi zolemba zina zomwe zimatsegula njira zambiri zothandizira kuti ziwalo zambiri zogwirizana zimatumizidwe deta mwachindunji m'malo mwa ena onse pa intaneti monga ndi ma hubs
- Mayendedwe a pa intaneti akuonjezeranso zamtundu wa kusintha kwa intaneti pothandizira mauthenga kunja kwaokha kupita ku mawebusaiti ena, kuwaphatikizana pokha popanda kusokoneza ntchito ya aliyense payekha.
- Munthu wobwereza makina amalandira zizindikiro zomwe zimatumizidwa kudutsa kugwiritsira ntchito pakompyuta ndikukweza mphamvu zawo (monga mphamvu zamagetsi kapena zamagetsi) kuti zizindikiro ziziyenda ulendo wautali
- Masiku ano, mtundu wa chipangizochi umagwirizanitsa mitundu iwiri yosiyanasiyana ya maukonde omwe amatha kusonkhana pamodzi zomwe zingakhale zosagwirizana, monga milatho yomwe imathandiza zipangizo zopanda zingwe kuti zilowe muzenera. (Masiku ano bridge yamakono nthawi zambiri imagwirizanitsidwa ndi mitundu ina ya zipangizo.)
