UKUXHUMANA NGEZINTO EZINTSHA

Izisekelo Zokuklama Inethiwekhi Ukuklama inethiwekhi kuyinqubo yokuhlela, ukwakha, nokuphatha ingqalasizinda yokuxhumana kwedatha ukuze amadivayisi—njengamakhompyutha, amaseva, amaswishi, ama-router, izindawo zokufinyelela, namadivayisi e-IoT—akwazi ukuxhuma ngokuphephile, ngokuzinzile, nangokusebenza kahle. Esikhathini sezinsizakalo zedijithali, ukuklama inethiwekhi akukhona nje “ukuxhuma izintambo” noma ukufaka i-Wi-Fi, kodwa kunalokho ukudala ukwakheka okungasekela izidingo zebhizinisi, ukusabalala, ukukhula, kanye… Funda kabanzi

Ubuchwepheshe Bokuxhumana be-IoT I-Internet of Things (IoT), noma "i-Internet of Everything," ingumqondo lapho amadivayisi ahlukahlukene angokwenyama—kusukela ezinzwa zokushisa namakhamera kuya emishinini yasefektri nasezimotweni—axhunywe kwi-inthanethi ukuthumela nokwamukela idatha. Ukuze i-IoT isebenze kahle, idinga "ibhuloho" eliyisihluthulelo: ubuchwepheshe bokuxhumana. Ngaphandle kokuxhumana okufanele, amadivayisi e-IoT awakwazi ukudlulisa ulwazi ngokushesha, … Funda kabanzi

Ukubaluleka Kokugcina Idatha Esikhathini sanamuhla sedijithali, idatha isibe enye yezimpahla ezibaluleke kakhulu kubantu ngabanye kanye nezinhlangano. Izithombe zomndeni, amadokhumenti omsebenzi, amarekhodi ezezimali, izizindalwazi zamakhasimende, ngisho nemibiko yebhizinisi—konke kugcinwa ngedijithali. Kodwa-ke, abantu abaningi baqaphela kuphela ukubaluleka kwedatha lapho kuvela inkinga: i-laptop elahlekile, ifoni ephukile, i-hard drive ngokuzumayo ingasafundeki,… Funda kabanzi

Izici Zama-Microwave Ama-Microwave ayingxenye ye-spectrum kagesi esetshenziswa kabanzi empilweni yanamuhla, kusukela ekuxhumaneni okungenantambo kuya kumishini yasekhaya. Nakuba evame ukuhlotshaniswa nama-oven e-microwave, ama-microwave empeleni anendima ebanzi kakhulu, ikakhulukazi kubuchwepheshe be-radar, amasathelayithi, amanethiwekhi eselula, kanye nezinhlelo zokuzulazula. Ukuze uqonde ukuthi kungani ama-microwave… Funda kabanzi

Umphumela Wesimo Sezulu Ekuxhumaneni Okungenantambo Ukuxhumana okungenantambo sekuwumgogodla wemisebenzi eminingi yesimanje—kusukela ezingcingweni zocingo kanye nokufinyelela ku-inthanethi kuya ezinhlelweni zokuzulazula kuya ekuxhumaneni okuphuthumayo. Nakuba kubonakala sengathi “kungabonakali” futhi kulula, izimpawu ezingenantambo empeleni zisakazeka ngokusebenzisa indlela enamandla kakhulu: umkhathi. Ngaphakathi komkhathi, isimo sezulu siyisici esibalulekile esingathinta ikhwalithi, ububanzi, kanye nokuthembeka kokuxhumana… Funda kabanzi

Izimiso Zokusebenza ze-Router kanye ne-Switch Kumanethiwekhi ekhompyutha anamuhla, ama-router kanye nama-switch kumadivayisi amabili avame ukutholakala, kusukela emakhaya kuya emahhovisi nasezikoleni kuya ezikhungweni zedatha ezinkulu. Nakuba womabili exhuma amadivayisi ukuze akwazi ukuxhumana, asebenza ngezindlela ezahlukene futhi adlala izindima ezahlukene. Ukuqonda izimiso zokusebenza zama-router kanye nama-switch kubalulekile… Funda kabanzi

Ukusebenzisana kwe-IT kanye nezokuxhumana: Emashumini eminyaka amuva nje, ubuchwepheshe bolwazi (i-IT) kanye nezokuxhumana kuye kwathuthuka ngokushesha futhi kwaxhumana kakhulu. Nakuba ukuxhumana kwakuye kwafana nokuthumela imiyalezo ngezwi kanye nombhalo, indima yakho manje isiye yanda yaba umgogodla wokuxhumana kwedatha, izinhlelo zokusebenza ezixhumanisayo, ukubalwa kwamafu, amadivayisi ahlakaniphile, ngisho nezinhlelo zebhizinisi eziyinkimbinkimbi. Ngakolunye uhlangothi, i-IT… Funda kabanzi

Imishini Yokuhlola Inethiwekhi Ezweni lobuchwepheshe bolwazi, amanethiwekhi ekhompyutha ayinsika yokuxhumana kwedatha—kusukela ekufinyeleleni i-inthanethi ehhovisi, ukuxhumana phakathi kwamaseva ezikhungweni zedatha, kuya kumanethiwekhi angenantambo emakhaya. Uma inethiwekhi iwa, umthelela ungaba mkhulu: isevisi ehamba kancane, ukungasebenzi kwezinhlelo zokusebenza, ukuphazamiseka kokufinyelela ezinhlelweni ezibalulekile, ngisho nokulahlekelwa yibhizinisi. Ngakho-ke, ukuhlolwa kwenethiwekhi… Funda kabanzi

Indima ye-DNS Ekuxhumekeni Kwenethiwekhi Ezweni lamanethiwekhi ekhompyutha kanye ne-inthanethi, abasebenzisi bajwayele ukuthayipha amakheli afana ne-www.google.com noma i-portal.sekolah.id ukuze bafinyelele izinsizakalo ezithile. Kodwa-ke, ngemuva kwalokhu kulula kukhona uhlelo olubalulekile olusebenza njenge-"phone book" ye-inthanethi: i-DNS (Domain Name System). Ngaphandle kwe-DNS, abasebenzisi kuzodingeka babambe ngekhanda uchungechunge lwamakheli e-IP afana ne-142.250.190.14 ukuze bafinyelele iwebhusayithi... Funda kabanzi

I-Fiziksi Yokuxhumana Ngocingo Ukuxhumana ngocingo kuyinqubo yokuthumela ulwazi kusuka endaweni eyodwa kuya kwenye kusetshenziswa indlela ethile, kungaba ngentambo noma engenantambo. Ngemuva kobuchwepheshe esibusebenzisa nsuku zonke—omakhalekhukhwini, i-Wi-Fi, umsakazo, ithelevishini, ngisho namasathelayithi—kukhona izimiso ze-fiziksi ezisebenza njengesisekelo sazo. Ukuqonda i-fiziksi yokuxhumana ngocingo kusho ukuqonda ukuthi izimpawu zenziwa kanjani, zithwalwa kanjani amaza kagesi, nokuthi... Funda kabanzi
