Computer ports iyo inokosha yezvinhu zvose zvekombiyuta. Makombiyuta emapuraneti anopa maitiro uye zvinoshandiswa zvinoshandiswa purogiramu yacho inoda kuyanana nemitambo nemakombiyuta. Nzvimbo dzinonyanya kukosha pamakombiyuta dzinoshandiswa pakushandura kombiyuta.
Physical Ports
Nzvimbo inogona kunge iri yemuviri kana yega. Zvigadzirwa zvemasikirwo emitambo zvinobvumira kubatana kwetambo kumakombiyuta, ma routers , modems , nemamwe magadzirirwo emitambo. Mhando dzakasiyana-siyana dzehutachiona hunowanikwa pamakombiyuta network hardware dzinosanganisira:
- Ethernet ports : Nhamba dzepakati dzakagadzirwa nematanda eEthernet cables
- USB ports : Rectangular-shaped connection points for USB cables
- Serial ports : Rutivi rwakagadzikana hutano hwemaseri serial
Ports mu Wireless Networking
Nepo makombiyuta anotsiwa nekombiyuta anotenderera pamakona emitambo uye nheyo, mitambo isina mashizha haifaniri. Wi-Fi miterevhizheni, semuenzaniso, shandisa nhamba dzedhirire dzinomiririra kuiswa kweredhiyo.
Internet Protocol Ports
Virtual ports ndiyo inokosha yeInternet Protocol (IP) networking. Aya mahwende anobvumira mapurojekiti ekugadzirira kugovera hardware zvidzidzo pasina kupindirana. Makombiyuta uye ma router zvinongodzora zviri nyore kufamba kwenzira yekutengesa kuburikidza nematokari avo chaiwo. Network firewalls kuwedzera kupa humwe hutongi pamusoro pekuyerera kwemugwagwa pane imwe nhandare yepamusoro yekuchengetedza zvinangwa.
MuIndaneti, mahara aya aya akaverengwa 0 kusvika ku 65535. Kuti uwane mamwe, ona Chii Inonzi Port Nhamba?
Matambudziko nePorts muComputer Networking
Zviteshi zvepanyama zvinogona kumira kushanda kune chero zvikonzero zvakati. Zvinokonzera kutadza kwechikwata zvinosanganisira:
- Simba surges (pane zvigadzirwa zvakanyatsobatanidzwa nemaoko emagetsi)
- Mvura inokuvara
- Kukundikana mukati
- Kukuvadza kunokonzerwa nepini kubva pamatare (zvichikonzerwa nekuisa makanda nesimba zvakanyanya, kana kuedza kuvhara rudzi rwakashata rwekambo muchiteshi).
Kunze kwekukuvadza kwepini, kuongorora kwenyama ye hardware yegungwa hakuzowani chinhu chakajeka chakaipa. Kukundikana kwechimwe chikwata pane chimwe chinhu chinonzi multiport device (yakadai se network router ) hachikanganisa kushanda kweimwe nzvimbo dzechikepe.
Inokurumidza uye tsananguro yehutachiona chepanyama haigoni kutsanangurwa chete nekuongorora muviri. Dzimwe shanduro dzeEthernet , somuenzaniso, dzinoshandisa papamusoro pe 100 Mbps , asi dzimwe dzinotsigira Gigabit Ethernet , asi chibatanidza chemuviri chakafanana mumatambudziko maviri. Saizvozvowo, dzimwe USB dzinotsigira version 3.0 asi vamwe vanotsigira 2.x kana dzimwe nguva kunyange 1.x.
Dambudziko rinowanzosangana nemunhu anotarisana nepamhenderekedzo yepamusoro ndeyekuchengeteka kwehutano. Vanoshamwaridzana neIndaneti vanowanzotarisa mabhiji emawebsite, routers, uye chero imwe mimwe mitambo. A network network firewall zvikuru inobatsira kudzivirira kurwisana uku nekudzivirira kusvika kune zvikepe zvichienderana nhamba yavo. Kuti ive yakabudirira, moto unodzima moto unowanzove wakanyanyisa uye unowanzovhara motokari iyo munhu anoda kuitendera. Nzira dzekugadzirisa mitemo iyo moto unoshandisa pakugadzira migwagwa yakadai sekufambisa mitemo inogona kuva yakaoma zvikuru kune vasinaprofessionals kutarisira.
