Isho ukuthini iwebhu yomhlaba wonke: Ukwembula imfihlakalo

Umbuzo othi “ingabe iwebhu yomhlaba wonke isho ukuthini” uvame kakhulu kunalokho esingakucabanga. Empeleni, i-World Wide Web, eyaziwa nangokuthi i-WWW noma “iwebhu” nje, iwuhlelo lokusabalalisa imibhalo exhumene ne-hypertext etholakala nge-inthanethi. Igama elithi "World Wide Web" lihumushela olimini lwesi-Spanish ngokuthi "Inethiwekhi Yomhlaba" noma "Inethiwekhi Yomhlaba Wonke", okubonisa isimo sayo esixhumene nokufinyeleleka kwamanye amazwe.

Kodwa isho ukuthini ngempela le ncazelo? Ake sicabange iwebhu njengomtapo wolwazi wedijithali omkhulu. Ikhasi lewebhu ngalinye lifana nencwadi ekulo mtapo wolwazi, futhi izixhumanisi zifana nezinkomba ezisisusa encwadini eyodwa zisiyise kwenye. Njengoba nje umtapo wezincwadi ophathekayo unohlelo lokuhlela nokuthola izincwadi, iwebhu inezinqubo zayo zokuhlela nokufinyelela olwazini.

Kubalulekile ukuqaphela ukuthi, nakuba evame ukusetshenziswa ngokushintshana, i-World Wide Web kanye ne-inthanethi akuyona into efanayo. I-inthanethi inethiwekhi ebonakalayo yamakhompuyutha axhumene, kuyilapho Iwebhu iyisevisi esebenza kuleyo nethiwekhi. Kufana nomehluko phakathi kwemigwaqo (i-inthanethi) nezimoto ezihamba kuyo (iWebhu).

Umsuka we-WWW: Uhambo oludlulele kobuchwepheshe

Ukuze siqonde ngempela ukuthi iwebhu yomhlaba wonke isho ukuthini, kufanele sibuyele emuva emsuka wayo. Umlando we-WWW waqala ngo-1989, lapho u-Tim Berners-Lee, usosayensi waseBrithani osebenza e-CERN (European Organization for Nuclear Research), ehlongoza uhlelo lokuphatha ulwazi.

UBerners-Lee ukhungathekile ngobunzima bokwabelana ngolwazi phakathi kososayensi basemanyuvesi nasezikhungweni ezahlukene emhlabeni jikelele. Umbono wakhe kwakuwukudala indawo yolwazi lomhlaba wonke lapho abantu bengabelana futhi bafinyelele imibhalo nolwazi.

Ngo-1990, kanye nozakwabo uRobert Cailliau, uBerners-Lee bathuthukisa ubuchwepheshe obuthathu obuyisisekelo obuseyisisekelo sewebhu yanamuhla:

1. I-HTML (Ulimi Lwemakhaphu Ye-HyperText): Ulimi lwemakhaphu lokudala amakhasi ewebhu.
2. I-URI (I-Uniform Resource Identifier): Uhlobo “lwekheli” eliyingqayizivele lesisetshenziswa ngasinye kuwebhu.
3. I-HTTP (I-HyperText Transfer Protocol): Ivumela ukubuyiswa kwezinsiza ezixhunyiwe kuwebhu.

Ngo-Agasti 6, 1991, uBerners-Lee washicilela isizindalwazi sokuqala emhlabeni, echaza iphrojekthi yeWebhu Yomhlaba Wonke nokuthi isetshenziswa kanjani. Lesi sikhathi siphawula ukuzalwa okusemthethweni kweWWW njengoba sisazi namuhla.

I-Basic Architecture: Izinsika Zewebhu

Manje njengoba sesihlole ukuthi iwebhu yomhlaba wonke isho ukuthini kanye nemvelaphi yayo, kubalulekile ukuqonda ukwakheka kwayo okuyisisekelo. Iwebhusayithi isekelwe ezinsikeni ezintathu eziyisisekelo:

I-HTTP: Ulimi lwewebhu

I-Hypertext Transfer Protocol (HTTP) iyinhliziyo yokuxhumana kuwebhu. Isebenza njengesithunywa phakathi kwesiphequluli sakho neseva yewebhu. Uma uthayipha i-URL esipheqululini sakho, uthumela isicelo se-HTTP kuseva. Iseva iphendula ngokuthumela idatha edingekayo ukuze kuboniswe ikhasi lewebhu.

I-HTML: Uhlaka lwamathambo ewebhu

Ulimi lweMarkup Hypertext (HTML) wulimi olujwayelekile lokudala amakhasi ewebhu. Ihlinzeka ngesakhiwo esiyisisekelo sesayithi, esibuye sithuthukiswe futhi silungiswe ngobunye ubuchwepheshe obufana ne-CSS ne-JavaScript. I-HTML isebenzisa “amathegi” ukuchaza izinhlobo ezahlukene zokuqukethwe, njengezihloko, izigaba, izithombe, nezixhumanisi.

I-URL: Amakheli e-Cyberspace

I-Uniform Resource Locator (URL) ifana nekheli lendlu emhlabeni wedijithali. Yonke insiza ekuwebhu, noma ngabe yikhasi le-HTML, isithombe, noma ifayela le-PDF, ine-URL yayo ehlukile. Lokhu kuvumela abasebenzisi neziphequluli ukuthi bathole futhi bafinyelele izinsiza ezithile kuWebhu Yomhlaba Wonke.

Ukuvela Kwewebhu Yomhlaba Wonke: Ukusuka kuWebhu 1.0 kuye ku-3.0

Impendulo yokuthi "isho ukuthini iwebhu yomhlaba wonke" iye yavela ngokuhamba kwesikhathi. Iwebhu ayimile; udlule ezigabeni ezimbalwa zokuthuthuka:

1. Iwebhu 1.0 (1989-2004): Iwebhu yokufunda kuphela. Amasayithi abemile futhi ukusebenzisana komsebenzisi bekunomkhawulo.
2. I-Web 2.0 (2004-okwamanje): Iwebhu yezenhlalo neyokuhlanganyela. Amanethiwekhi omphakathi, amabhulogi kanye nama-wikis avele, okuvumela abasebenzisi ukuthi bakhe futhi babelane ngokuqukethwe.
3. I-Web 3.0 (esafufusa): Yaziwa nangokuthi iwebhu ye-semantic. Ifuna ukwenza ulwazi oluku-inthanethi luqondakale kakhudlwana emishinini, okuvumela ukusesha okuhlakaniphile nokwenziwe kube ngokwakho.

Lokhu kuvelela kukhombisa ukuthi iwebhu isuke kanjani ekubeni ithuluzi lolwazi yaba inkundla yokubambisana futhi, okungenzeka, iye kumsizi ohlakaniphile.

Umthelela we-WWW emphakathini wanamuhla

Ukuqonda iwebhu yomhlaba wonke kusho ukubona umthelela wayo omkhulu emphakathini. Iwebhu iguqule cishe zonke izici zempilo yethu:

Ukuxhumana Kwembulunga yonke: Ukunqamula Izithiyo

Iwebhu yenze ukuxhumana okusheshayo kwaba khona emhlabeni jikelele. Kusukela ku-imeyili kuya kumakholi wevidiyo, kwenze abantu abavela emhlabeni wonke basondelana ndawonye, ​​benciphisa imigoqo yendawo kanye nezamasiko.

I-E-commerce: Inguquko kwezohwebo

I-E-commerce iguqule indlela esithenga ngayo nesithengisa ngayo. Izinkampani ezifana ne-Amazon ne-Alibaba sezikhule zaba izikhondlakhondla zomhlaba, kanti amabhizinisi amancane manje angafinyelela amakhasimende emhlabeni jikelele.

Imfundo eku-inthanethi: Ulwazi ngokuchofoza inkinobho

Iwebhu inokufinyelela kwentando yeningi olwazini. Izinkundla zokufunda eziku-inthanethi, izinsiza zemfundo ezivulekile kanye nezifundo ezinkulu ze-inthanethi ezivulekile (ama-MOOC) zenze imfundo yafinyeleleka kakhulu kunangaphambili.

Izinselelo nezingxabano enkathini yeWebhu Yomhlaba Wonke

Ngaphandle kwezinzuzo zayo eziningi, iwebhu futhi ilethe nezinselelo ezibalulekile:

1. Ubumfihlo nokuphepha: Ukuqoqwa nokusetshenziswa kwedatha yomuntu siqu kuwukukhathazeka okukhulayo.
2. I-Disinformation:Ukuba lula kokwabelana ngolwazi kuholele ekusabalaleni kwezindaba ezingamanga nolwazi olungaqondile.
3. Ukuhlukaniswa kwedijithali: Akuwona wonke umuntu onokufinyelela okulinganayo kuwebhu, okungase kubhebhethekise ukungalingani okukhona.
4. Ukuphepha kwe-cyber: Ukuhlaselwa kwe-Cyber ​​​​kanye nokwebiwa kwedatha kuyizinsongo eziqhubekayo.

Ukubhekana nalezi zinselele kubalulekile ekuqinisekiseni ukuthi iwebhu ihlala inamandla emphakathini.

Uma ucabanga ukuthi iwebhu yomhlaba wonke isho ukuthini, kungokwemvelo ukuzibuza ngekusasa layo. Amanye amathrendi asafufusa ahlanganisa:

• I-Artificial Intelligence kanye Nokufunda Ngomshini: Lobu buchwepheshe benza iwebhu ihlakaniphe futhi ibe ngeyakho kakhulu.
• I-Intanethi Yezinto (IoT)Iwebhu inweba ngaphezu kwemishini evamile ukuze ifake izinto ezixhumene nsuku zonke.
• I-Virtual and Augmented Reality: Lobu buchwepheshe buthembisa ukudala umuzwa wewebhu ogxile kakhulu.
• Blockchain: Kungase kuguqule ukuphepha kanye nokwethenjwa kokwenziwayo okuku-inthanethi.

Ikusasa lewebhu lithembisa ukuthi lizojabulisa futhi liguqule njengesikhathi salo esidlule.

Isiphetho sokuthi kusho ukuthini iwebhu yomhlaba wonke

Sengiphetha, i-World Wide Web ingaphezu kwenethiwekhi yemibhalo exhumene. Kuyindwangu yedijithali ehlanganisa isintu, yenza kube lula ukushintshana kolwazi futhi iqhubekisele phambili izinto ezintsha. Kusukela ekuqaleni okuthobekile kuya endaweni yayo yonke indawo, iwebhu ichaze kabusha ukuthi siphila kanjani, sisebenza futhi sixhuma kanjani.

Ukuqonda ukuthi iwebhu yomhlaba wonke isho ukuthini ukuqonda amandla aguqulayo kakhulu enkathini yethu.
