Nidaamka Xakamaynta gudbinta (TCP) wuxuu isticmaalaa habab isgaarsiineed oo la yiraahdo dekadaha si ay u maareeyaan arjiyada kala duwan ee ku shaqeeya qalab isku mid ah. Si ka duwan sida dekadaha caadiga ah ee kombiyuutarada sida dekadaha USB-ga ama dekadaha Ethernet , dekadaha TCP waa kuwa loo isticmaali karo barnaamijyada loo yaqaan "virtual - programmable" oo u dhaxeeya 0 ilaa 65535.
Inta badan dekadaha TCP waa kanaal guud oo ujeedadiisu tahay in loo waco adeegga sida loo baahdo laakiin haddii kale fadlan fadlan. Hase yeeshee, qaar ka mid ah dekadaha hoose ee lambarrada ah, ayaa udubdhexaad u ah codsiyada gaarka ah. Inkastoo inta badan dekadaha TCP-ga ay ka mid yihiin codsiyada aan jirin, qaar waa kuwo caan ah.
01 ee 08
Dukumintiga TCP 0
TCP dhab ahaantii uma adeegsanayso dekedda 0 ee xidhiidhka shabakadda, laakiin dekkani si fiican ayuu u yaqaanaa barnaamijyada shabakadda. Barnaamijyada barnaamijka TCP waxay isticmaalaan dekada 0 si ay uga codsadaan deked la heli karo oo loo qoondeeyay nidaamka hawlgalka. Tani waxay ka badbaadisaa barnaamijka in uu qaato ("hardcode") lambarka dekedda oo aan si fiican u shaqayn karin xaaladda. More »

Dekadaha TCP 20 iyo 21
Nidaamyada FTP waxay adeegsadaan dekedda TCP 21 si ay u maareeyaan kooxahooda FTP. Kooxdu waxay dhegeysanaysaa amarrada FTP ee imanaya dekedan waxayna u jawaab celinayaan. Hannaanka firfircoon ee FTP, adeegsaduhu wuxuu intaa dheer isticmaalaa dekedda 20 si loo bilaabo xogta wareejinta ee macmiilka FTP.

Dekedda TCP 22
Shukumo ammaan ah (SSH) waxay isticmaashaa dekadda 22. Xafiisyada SSH waxay dhageystaan dekedda codsiyada soo gelitaanka macaamiisha fog. Sababtoo ah nooca isticmaalka this, dekadda 22 ee server kasta oo si joogta ah ayaa si joogta ah kufsanaya by hackers shabakad iyo wuxuu ahaa mawduucyo badan oo baadho in bulshada ammaanka network. Qaar ka mid ah u doodayaasha amniga waxay ku talinayaan in maamulayaasha ay u wareejiyaan SSH-ga si ay uga caawiyaan in ay ka hortagaan weerarradan, halka kuwo kalena ay ku doodayaan in ay tahay kaliya marxalad ka-faa'iideysasho leh.

UDP dekadaha 67 iyo 68
Nidaamyada Qalabka Nabadgalyada Qalabka Isku Dhaafka ah (DHCP) waxay isticmaalaan UDP-da 67 si loo dhagaysto codsiyada halka macaamiisha DHCP ay kugula hadlaan UDP-da 68.

Dhanka TCP 80
Argagax ahaan hal dukumiinti ugu caansan ee internetka, dekedda TCP 80 waa midka default in HyperText Transfer Protocol (HTTP) Websocodka dhagaysta dhagaysta codsiyada browserka.

Dukumentiga UDP 88
Adeegga kubadda cagta ee Xbox Live wuxuu isticmaalaa lambaro dhowr ah oo kala duwan oo ay ku jiraan dekedda UDP 88.
07 of 08
UDP dekadaha 161 iyo 162
By default default Protocol Management Protocol (SNMP) wuxuu adeegsadaa UDP 161 si uu u diro oo uu helo codsiyada shabakadda la maareynayo. Waxay isticmaashaa dekedda UDP 162 taas oo ah midda ugu horaysa ee lagu helo xarigaha SNMP ee ka yimid qalabyada la koontaroolay.

Ports ka sareeya 1023
Lambarradaha dekadaha TCP iyo UDP inta u dhaxaysa 1024 iyo 49151 waxaa loo yaqaannaa dekedaha diiwaangashan . Hay'adda Internetka ee Maareynta Tirooyinka Internetka waxay haysaa liisto adeegyo ah iyaga oo isticmaalaya dekadaha kuwaas si loo yareeyo isticmaalka khilaafaadka.
Si ka duwan sida dekedaha leh lambarrada yaryar, horumarinta adeegyadda cusub ee TCP / UDP waxay dooran karaan lambar gaar ah si ay u diiwaan geliyaan IANA halkii ay ku lahaan lahaayeen lambar loo xilsaaray. Isticmaalka dekedaha diiwaangashan ayaa sidoo kale ka hortagaya xayiraadaha dheeraadka ah ee xaddidan ee nidaamyada ku shaqeeya dekedaha leh lambaro hoose.
