Iindlela transmission ulwazi - ukusuka codex ukuya e-mail

Ukususela kwixesha lakudala, kwimpucuko zisekelwe ukugcinwa kunye nokusasazwa kolwazi. Ekuhambeni kwexesha, iindlela ukudluliselwa iinkcukacha zitshintshile. Yonke le nto yaqala intetho. Ngamazwi omlomo kudlule sagas namabali, apho imbali abantu bavela. Ngoko ke iindlela indulumbane abathunywa kunye neeleta. Ukutyhubela iinkulungwane baye liphathiswe kwaye ebomini bethu ngokuqinileyo uqhagamshelo yomnxeba. Namhlanje, iileta iphepha phantse bawela zingasasetyenziswa, yaye kungekudala yeefoni endaweni ngokupheleleyo Internet. Ngakumbi nangakumbi abantu bakhetha ukunxibelelana nokwabelana ngolwazi hayi efowunini yaye nge kuthungelwano Internet, kuba zona nizimele ugqithiso lwedata ubuchwepheshe ngokukhawuleza.

Noko ke, nangona inkqubela zeteknoloji, enye yeendlela eziphambili Kwathi ulwazi ihlala iphepha. Namhlanje, amaxwebhu ayafumaneka kuzo zombini ephepheni kunye nefomu elektroniki. Kuba ukutshintshiselana amaxwebhu electronic suku ngalunye ekuphuhliseni ezintsha yokudlulisela ulwazi. Apha kwindawo yokuqala sithatyathwa e-mail. Ngayo, umamkeli ufumana ileta phantse kwangoko, ukuze abe nokuba naphi na ehlabathini. e-mail abancedisi umsebenzi sipho e-mail kubamba amawaka iibhokisi - ebizwa ngokuba yi-akhawunti. Ukongeza kwingcaciso ye-imeyile usasazwa ugqithiselwa nge ICQ, Skype kunye neenkqubo ezifanayo. Kukho kwakhona indlela elula kakhulu kunxibelelwano - kwinkomfa Internet. inkomfa zeefoni Internet zange indawo kuba ifuna uqhagamshelwano-high speed i-World Wide Web.

ukudluliselwa kolwazi lwenzeka mhlawumbi ngokusebenzisa uthungelwano kwikhompyutha okanye nge-elektroniki njenge CD-ROM, Flash-drives, kwaye kumphati SSD-drives. uthungelwano computer babe nodidi zabo. Ahluke ngokwemiqathango mmandla, ithopholoji, yaye indlela yolawulo. Abaninzi LANs coverage amancinci - umgama phakathi ezalathelwe yi ezimbalwa leemitha kuphela. Indawo yesibini kuhlala uthungelwano corporate - ukuba ziyafumaneka kwi-ofisi okanye kwishishini. I inkulu yinethiwekhi yemimandla, ukalisha ngokulandelelana, yahlulwe zengingqi nezehlabathi ngokubanzi.

Ngokutsho ithopholoji uthungelwano zahlulwe ngokweendidi ezintathu. Kweekhompyutha womnatha ibhasi odityaniswe umgca enye, kwaye ulwazi usasazwa ugqithiselwa kwi computer omnye uya ngoko nangoko zingafumaneka wonke umntu. Kwiindawo womnatha ring alandela omnye komnye. Ulwazi kuwo ezidluliselwa ngakwicala ngomoya omnye. womnatha Star ukuba iyunithi yolawulo engundoqo, leyo diverge ukusuka umgca-reyi kwezinye iindawo.

Iintlobo ulawulo womnatha ezimbini. Uhlobo "uhanjiselo-server 'inethiwekhi baleka iiseva ezinkulu, kunye nezinye computer kubaxumi kwaye kube nafuthe network. Xa uhlobo ad hoc zonke iindawo womnatha bayalingana ngokupheleleyo. Bathi umsebenzisi ngamnye isigqibo iifolda okanye iifayile ziya kuba yintoni kufumaneka kubo bonke. networks ezinjalo kakubi kakhulu ikhuselwe nxamnye kusiko.

Zonke iindlela kunokwenzeka ukudluliselwa data kube nemihlangano omnye. Oku kuquka ulwazi lomthumeli, ijelo ukudluliselwa kunye nolwazi receiver. Imiphantsi zahluke kwiqondo transmission ulwazi, kulinganiswa kwi amasuntswana / s kunye nemilinganiselo yayo iziphindwa. Uthungelwano Internet ehlabathini lonke imithombo yolwazi zibizwa ngokuba iiseva, ngelixa abo bayisebenzise - abathengi. Njengomthetho jikelele, umboleki engena uthungelwano lwehlabathi nge fibre-optic cable. Kutshanje, kunjalo, xa ukusetyenziswa okuqhelekileyo ziquka iindlela ukufikelela Internet engenazingcingo, ezisebenzisa ubugcisa ezifana Wi-Fi okanye Bluetooth. Umntu akakwazi kodwa ukukhumbula weselula, njengoko abantu abaninzi basebenzisa intanethi ehambayo okanye 3G-modem, esebenzisa WAP okanye GPRS iprotocol.

Ngoko ke, iindlela zothumelo ulwazi laphumelela kwenye de Internet evulekileyo. Kunye nokuphuhliswa kobuchwepheshe ezitsha i-World Wide Web liya lisiba nefikelelekayo ngakumbi, lo gama ayithatheli indawo zonke ezinye iindlela zonxibelelwano.
