Kodi kusintha njira?

Zonse Intaneti panopa alipo kutumiza mauthenga kupereka ntchito chofunika akhoza kugwiritsa ntchito mitundu iwiri ya kugwirizana - dera kusinthitsa, ndipo (kapena) phukusi. Kodi ndi mmene pyasiyana Chrixitu?

Tiyeni tiyambe ndi momwe maukonde dera-anazimitsa. Iwo anakaonekera anzawo ndi kusintha kaphukusi choncho, n'zosadabwitsa zosavuta kwambiri kuzitsatira. A chitsanzo chapadera cha Intaneti kuti amagwiritsa dera kusinthitsa - ulalo telefoni. N'zoonekeratu kuti kulola awiri wolembetsa mukhoza kuyamba kucheza, muyenera kukhazikitsa kugwirizana pakati pawo. E wolembetsa dials zingapo zomwe kwenikweni ndi lamulo siteshoni telefoni zida (kudya) ili therebetween bwino kugwirizana mizere iwiri - kuchokera E ndi ku transponder (kutenga Mwachitsanzo, azilandira ali anali ndi siteshoni imodzi). Poyamba, imeneyi imagwira feelers makina pa yosavuta masensa udindo, ndiye, mkubwela njira digito, kukhazikitsa kusintha, koma mfundo akanali yemweyo. Dera kusinthitsa amapereka olembetsa ndi mzere wodzilamulira, amene ali awoawo mpaka kumapeto kwa gawoli. ubwino ndi zoonekeratu: mkulu kudalirika kulibe kufala kwa mapaketi kulamulira. Komabe, njira imeneyi mankhwala ndi chiwerengero cha olembetsa amakhala kwambiri wolowerera, kuyambira chiwerengero cha njira yochepa thupi. Ngakhale pofuna kuthetsa vutoli ntchito chisindikizo lakanthawi chabe, ena wogwirizira njira. Komanso, dera kusinthitsa mmodzi drawback - mzere kulankhulana wotanganidwa nthawi zonse ngakhale palibe kufotokoza zambiri pakati olembetsa lapansi. Mwachitsanzo, akucheza naye telefoni, inu kukacheza apo kompyuta ndi za ntchito yawo - njira adzakhala asungike kufikira mbendera amapita kuswa kugwirizana.

N'chifukwa chake Kenako anasiya commutation njira anabwera njira paketi kusinthitsa. kugwira ntchito kumaphatikizapo kabisidwe ndi partitioning opatsirana deta mtsinje mu angapo mapaketi munthu kuti ndi zochokera okwana kugwirizana wolandila zimafalitsidwa ndi apo amaphatikizidwa mu chakudya mtsinje. Kuti timvetse kusiyana njira ziwiri, tingagwiritse ntchito chitsanzo cha mzere zoyendera: pamene dera kusinthitsa mzere ukufanizidwa ndi njanji, ndi otaya deta - ndi zikuchokera zosiyanasiyana magalimoto. Ndi momveka bwino kuti njira kuchedwa kutsatira n'zochepa kwambiri, ndi kudalilika kwa mmodzi wa apamwamba. Pa nthawi yomweyo, pa njanji imeneyi nthawi yomweyo sanayende ndi nyimbo zingapo. Koma mizere ya paketi kusinthitsa - khwalala mkulu-liwiro ndi gulu multiband. The katundu (a mapaketi opatsirana) lagawidwa makina osiyanasiyana omwe nja mu otaya modes ena zoyendera akafike, kumene khamu la kamangidwe pachiyambi. Mu chitsanzo ichi msewu - ndi kulankhulana njira, ndi makina ndi deta mapaketi. Iwo Co-kulibe mwamtendere pa njira yomweyo, pafupifupi popanda kusokoneza kayendedwe wina ndi mzake. Kuchotserapo - kuchulukana, maloboti ndi zinthu nthenda (kuchedwa kumeneku). Ngakhale makina si anafika kumene akupita, buku la pempho akhoza anatumiza kachiwiri. Total buku opatsirana pa wagawo pamene paketi nthawi zambiri ndi apamwamba kwambiri kuposa zinachitikira njira.

Ambiri, kusinthitsa ndi kusinthana chilichonse kusintha limati. Mu njira zopezera ndipamene njira kwa deta akudutsa. The peculiarity lagona mu njira ya chipembedzo chake. Kusinthitsa si kutero wosokonezeka ndi wam'mbuyomu ntchito ndi kupeza njira mulingo woyenera.
