I-TCP / IP isetshenziswa izigidi zabantu nsuku zonke
I-Transmission Control Protocol (TCP) ne- Inthanethi Protocol (i-IP) yizinhlelo ezimbili ezihlukene zezinethiwekhi zenethiwekhi. Iprotocol isethi yokuvunyelwana kwezinqubo nemithetho. Lapho amakhompiyutha amabili elandela izinqubo ezifanayo-isethi efanayo yemithetho-bangakwazi ukuqonda kanye nokushintshanisa idatha. I-TCP ne-IP zivame ukusetshenziswa ndawonye, noma kunjalo, ukuthi i-TCP / IP isibe yisikhathi esijwayelekile sokubhekisela kulokhu okulandelana kwezivumelwano.
I-Transmission Control Protocol ihlukanisa umlayezo noma ifayela emaphaketheni adluliselwa phezu kwe-intanethi bese ephinde ahlangane lapho efika lapho eya khona. Inqubo ye-intanethi ibhekene nekheli lepakethe ngayinye ngakho ithunyelwa endaweni efanele. Ukusebenza kwe-TCP / IP kuhlukaniswe ngezigaba ezine, ngayinye enezivumelwano zayo ezivumelanisiwe:
- Isendlalelo se- Datalink sinezindlela nezinhlelo ezisebenza kuphela kusixhumanisi, okuyiyona ingxenye yenethiwekhi ehlangene nama-node noma ama-Host hosts kwinethiwekhi. Ama-protocols kusendlalelo afaka i-Ethernet ne-ARP.
- I- intanethi noma ukulayishwa kwenethiwekhi kuxhuma amanethiwekhi azimele ukuhambisa amaphakethe aqukethe idatha yonkana kwimingcele yenethiwekhi. Ama-protocols yi-IP ne-ICMP.
- Isendlalelo Sokuthutha sithinta ukuxhumana phakathi kwamabandla futhi sinesibopho sokulawula ukugeleza, ukwethenjelwa nokuxhunyaniswa kwe-multiplexing. Ama-protocols afaka i-TCP ne-UDP.
- Isendlalelo sohlelo lokusebenza lubeka izinga lokushintshaniswa kwedatha yezicelo. Ama-protocols afaka i-HTTP, i-FTP, i-POP3, i-SMTP, ne-SNMP.
I-TCP / IP isebenza ngokuqondile ekuxhumaneni kwenethiwekhi lapho ukuthutha kwe-TCP kusetshenziselwa ukuletha idatha kuwo wonke amanethiwekhi we-IP. I-proxy okuthiwa "ukuxhumeka kokuxhumeka", i-TCP isebenza ngokusungula uxhumano oluthile phakathi kwamadivayisi amabili ngochungechunge lwesicelo nokuphendula imilayezo ethunyelwe kunethiwekhi yomzimba.
Amakhompiyutha amaningi abasebenzisi baye bazwa igama elithi TCP / IP ngisho noma abazi ukuthi lisho ukuthini. Umuntu ovamile kwi-intanethi usebenza endaweni enkulu ye-TCP / IP. Iziphequluli zewebhu , isibonelo, sebenzisa i-TCP / IP ukuxhumana namaseva wewebhu. Izigidi zabantu zisebenzisa i-TCP / IP nsuku zonke ukuthumela i-imeyili, ukuxoxa nge-intanethi nokudlala imidlalo ye-intanethi ngaphandle kokwazi ukuthi isebenza kanjani.
