I- Transmission Control Protocol (TCP) isebenzisa iqoqo leziteshi zokuxhumana ezibizwa ngamaports ukuphatha phakathi kwezicelo eziningi ezahlukene ezisebenza kudivayisi efanayo. Ngokungafani namapayipi angokomzimba kumakhompyutha afana namachibi e-USB noma amarekhodi e- Ethernet , amathrekhi e-TCP angenayo - okufakiwe okufakiwe kungabalwa phakathi kuka-0 no-65535.
Izindawo eziningi ze-TCP ziyiziteshi zomhlaba jikelele ezingahle zibizwe enkonzweni njengoba kudingeka kepha ngaphandle kwalokho zihlale zingenzi lutho. Amanye amabhulogi angaphansi, Nokho, anikezelwe ezenzweni ezithile. Ngenkathi izikebhe eziningi ze-TCP zingezinhlelo zokusebenza ezingasekho, ezinye zithandwa kakhulu.
01 ngo-08
I-TCP port 0
I-TCP ayisebenzisi empeleni i-port 0 yokuxhumana kwenethiwekhi, kodwa leli port liyaziwa kakhulu kubahleli benethiwekhi. Izinhlelo ze-TCP zetekisi zisebenzisa i-port 0 ngomhlangano ukuze zicele ichweba elitholakalayo likhethwe futhi linikezwe uhlelo lokusebenza. Lokhu kusindisa umhleli okumele akhethe ("i-hardcode") inombolo ye-port engase ingasebenzi kahle ngesimo. Okuningi "

Amapayipi we-TCP angu-20 no-21
Amaseva e- FTP asebenzisa i-TCP port 21 ukuphatha uhlangothi lwawo lwezinhlelo ze-FTP.Isiphakeli lilalela imiyalo ye-FTP efika kule port bese iphendula ngokufanele. Emoyeni esebenzayo ye-FTP, iseva ngokungeziwe isebenzisa i-port 20 ukuqala ukudluliswa kwedatha emuva kuklayenti le-FTP.
03 ngo-08
I-TCP port 22
I-Shell ephephile (i-SSH) isebenzisa i-port 22. amaseva we-SSH alalela kule port for izicelo ezingenayo zokungena ngemvume kusuka kumakhasimende akude. Ngenxa yemvelo yalokhu kusetshenziselwa, i-port 22 yanoma yisiphi isiphakeli esidlangalaleni ngokuvamile ihlolwe ngabaduni bezinhlelo zenethiwekhi futhi ihlolwe ngokucophelela emphakathini wokuphepha wenethiwekhi. Abanye abameli bezokuphepha batusa ukuthi abaphathi bathuthele ukufakwa kwabo kwe-SSH esangweni elihlukile ukusiza ukugwema lokhu kuhlasela, kuyilapho abanye bephikisana nalokhu kungumsebenzi owusizo ophansi.

Ama-UDP amachweba angu-67 no-68
Ama-Dynamic Host Configuration Protocol (DHCP) amaseva asebenzisa i-UDP port 67 ukulalela izicelo ngenkathi amaklayenti e-DHCP ekhuluma kwi-port ye-UDP 68.
05 ka-08
I-TCP port 80
Ngokusobala ichweba elidume kakhulu kunazo zonke kwi-inthanethi, i-port ye-TCP 80 yi-default ukuthi amaseva weWebhu ye- HyperText Transfer Protocol (HTTP) weWebhu alalela izicelo zesiphequluli sewebhu.
06 ka-08
I-UDP port 88
Isevisi yokudlala ye-Xbox Live Inthanethi isebenzisa izinombolo eziningana ze-port ezibandakanya i-UDP port 88.
07 ngo-08
Amapayipi akwa-UDP angu-161 no-162
Ngokuzenzakalelayo i- Simple Network Management Protocol (SNMP) isebenzisa i-UDP port 161 yokuthumela nokuthola izicelo kwinethiwekhi ephethwe. Isebenzisa i-port ye-UDP 162 njenge-default yokuthola izicupho ze-SNMP kumadivayisi aphethwe.

Amapayipi angaphezulu kuka-1023
Izinombolo zezindiza ze-TCP ne-UDP phakathi kuka-1024 no-49151 zibizwa ngokuthi izikebhe ezibhalisiwe . I-Intanethi Yanikezwe Izinombolo Zokuphatha igcina uhlu lwezinsizakalo ezisebenzisa lezi zichweba ukuze kuncishiswe ukusetshenziswa okuphikisanayo.
Ngokungafani namaports anezinombolo eziphansi, abathuthukisi bamasevisi amasha we-TCP / UDP bangakhetha inombolo ethile ukuze babhalise ne-IANA kunokuba babe nenombolo abelwe yona. Ukusebenzisa amaphethelo abhalisiwe futhi kugwema imikhawulo eyengeziwe yokuphepha ukuthi izinhlelo zokusebenza zisezintabeni ezinezinombolo eziphansi.
