Zviri Mukati
Kunzwisisa musiyano uripo pakati peserial uye USB yekubatanidza kwakakosha munyika yanhasi yetekinoroji. Izvi zvinongedzo zvakakosha pakufambisa data uye kubatanidza zvishandiso zvekombuta. Serial ports yagara ichishandiswa kubatanidza makombiyuta ekutanga. Zvichakadaro, USB ports inoramba iri yakasarudzika yekubatanidza yemagetsi yanhasi nekuda kwekureruka kwavo uye nekumhanya.
Sezvo tekinoroji ichifambira mberi, kusarudzwa kwezviteshi izvi kunowedzera kukosha. Zvinokanganisa mashandisiro atinoita tekinoroji yekare neitsva. Iyi positi inotarisa mune izvo zvinosiyanisa serial uye USB interfaces. Ichatarisawo nhoroondo yavo uye kushandiswa kwemazuva ano. Izvi zvichakubatsira iwe mukusarudza yakanakisa yekubatanidza kune zvaunoda chaizvo.
Key Takeaways
Serial ports uye USB ports zvakakosha pakufambisa kwedata.
Serial ports inoonekwa senhaka tekinoroji, nepo USB madoko ari akajairwa mumidziyo yemazuva ano.
Kunzwisisa zviteshi izvi kunobatsira kukwirisa mashandisirwo ekare uye matsva emakombuta peripherals.
Kuenzanisa maitiro avo kunogona kutungamira sarudzo dzekubatanidza dzinoshanda.
Nhoroondo uye Evolution yeSerial uye USB Ports
Nyika yedata ports yakachinja zvakanyanya mumakore. Yakatanga nekureruka serial kutaurirana uye ikozvino tine inokurumidza Universal Serial Bus (USB). Ichi chikamu chinokutora iwe parwendo kubva kune yekutanga serial ports kuenda kune inokurumidza USB tekinoroji. Tichatarisa nguva dzakakosha uye zvigadzirwa zvakachinja machinjiro atinoita data.
A. Kuvandudzwa kweSerial Ports
Serial ports yakatanga nemaprotocol akaita seRS232, RS485, uye RS422. Izvi zvinogadzira danho rekuchinjisa data pakati pemidziyo. RS232, semuenzaniso, yakaunzwa muma1960 uye yaive yakajairika mumakomputa uye network gear.
Nekufamba kwenguva, zvibatanidza zvakava zvidiki. Takatama kubva kuDB25 hombe yekubatanidza kuenda kune diki DB9 yekubatanidza. Iyo COM chiteshi yaive kiyi mumakomputa ekutanga, aishandiswa kune peripherals senge mbeva nemamodemu.
B. Kubuda kwe USB Ports
USB yakauya pakati pe-1990s uye yakachinja zvese. Yakaita kuti michina yekubatanidza zvive nyore uye nekukurumidza. USB yakagadzirirwa kutsiva akawanda ekubatanidza neyakajairwa chiteshi.
Mukana wakakura we USB yaive yayo plug-uye-kutamba chimiro. Izvi zvaireva kuti unogona kuwedzera kana kubvisa zvishandiso usina kutangazve komputa yako. Izvi zvakaita kuti kushandisa zvishandiso kuve nyore uye zvakanyanya pasi rose.
Gare gare, ne USB 2.0 uye USB 3.0, tekinoroji yakawedzera nani. Yakakurumidza uye yakashanda nemimwe michina.

Inonyanya Kuzivikanwa Serial Ports
Kukurukurirana kweserial kwave kwakakosha mune komputa tech kwemakore. Iyo RS232 chiyero ndiyo yakajairika. Yakatanga ne teletypewriters uye ikava yekuenda kune yakawanda michina nekuti iri nyore uye inoshanda nemazvo.
RS232 tambo dzinowanzoshandisa DB9 uye DB25 zvibatanidza. Iyo DB9, kana DE-9, idiki uye inoshanda, inoshandiswa munzvimbo dzakawanda. Iyo DB25 yakakura uye yaishandiswa mumakomputa ekare nemidziyo.
Izvo zviteshi zvezviteshi izvi zvakavabatsira kuti vave nemukurumbira. Iyo RS232 yakajairwa yakave nechokwadi kuti data yakatumirwa zvakavimbika pamusoro pemadaro marefu. Kunyangwe USB yatora, RS232 tambo uye maconnectors achiri kushandiswa mune mamwe minda. Vanokosheswa kuvimbika kwavo uye nyore.
Kuziva nezve DB9 neDB25 zvibatanidza zvinotibatsira kuona kuti serial communication yakashanduka sei. Inoratidza kuti aya makubatanidza akaumba sei tech munzira dzakawanda.
Misiyano Yakakosha Pakati peSerial uye USB Ports
Kunzwisisa mutsauko uripo pakati peserial uye USB ports kwakakosha. Ivo vanosiyana mukumhanya kwekufambisa data, kuendesa simba, uye mabatiro avanoita. Ichi chikamu chinovaenzanisa kuratidza mabasa avo akasiyana munyika yanhasi yetech.
A. Data Transfer Speed
USB ports inokurumidza kupfuura serial ports kana zvasvika pakumhanya kwekufambisa data. USB 3.0 inogona kufambisa data kusvika ku5 Gbps. Serial ports, kune rumwe rutivi, kumusoro kunze pa115.2 Kbps. Izvi zvinoita kuti USB ive nani yekukurumidza kutamisa data, sekufambisa mafaera makuru kana mavhidhiyo ekutepfenyura.
B. Kuendesa Simba
USB ports inogona kupa simba kumidziyo, kusiyana ne serial ports. Iyi ndiyo kiyi yekuchaja mafoni, mahwendefa, nezvimwe. Mitsva ye USB miitiro inogona kuendesa kusvika ku100 watts yesimba, ichiita kuti ive yakakura kune ese data uye simba zvinodiwa.
C. Kubatanidza uye Kugadzirisa
USB's plug-and-play chimiro chiri nyore kwazvo kushandisa. Unogona kubaya mukati nekubuda usina kudzima komputa yako, nekuda kwekupisa-swapping. Serial ports, zvisinei, inoda kugadzika kwebhuku uye inogona kuva inonyengera kuti uite zvakanaka.
D. Kugarisana uye Kusiyana-siyana
USB ports inoshanda neyakasiyana siyana yemidziyo, kubva nyore kusvika kune yakaoma. Serial ports, nepo akavimbika, ane mashoma uye anogona kusashanda nehutsva tech. Uyezve, serial kutaurirana kunogona kushandisa akasiyana voltage mazinga, zvichiita kuti zviome kubatanidza zvishandiso.

Zvakanakira uye Zvakaipa zveSerial Ports
Serial ports anga ari akakosha mukukurukurirana uye kutonga kwemakore. Kushandiswa kwavo kunoenderana nezvinodiwa zvekushandisa. Ivo vanozivikanwa nekuvimbika kwavo. Izvi zvinovaita vakakurisa pakutaurirana kureba, kunyanya mumaindasitiri nesainzi.
Serial ports zvakare inoshanda nemazvo nemidziyo yenhaka. Zvishandiso zvakawanda zvekare zvichiri kushandisa serial pakukurukurirana. Ivo zvakare vanobata ruzha kusadzivirirwa zvakanaka, izvo zvakakosha munzvimbo dzine yakawanda yekukanganiswa kwemagetsi.
Nekudaro, serial ports ine zvimwe zvakaderera. Imwe nyaya hombe ndeyekunonoka kwavo kutamisa data zvichienzaniswa neazvino interfaces se USB. Izvi zvinogona kuderedza maapplication anoda kukurumidza kuchinjanisa data. Zvakare, kutama kuenda kune anochinja-chinja mainterfaces se USB akaita kuti serial ports dzisanyanya kuwanda mumagetsi emazuva ano.
Zvakanakira uye Zvakaipa zve USB Ports
USB ports, senge USB 2.0 uye USB 3.0, yakashandura nyika yemagetsi evatengi. Ivo vanopa nekukurumidza kutumira data uye zvirinani multitasking rutsigiro.
Zvakanakira: USB ports ine simba rakawanda. Vanogona kupa simba rakawanda kumidziyo, ichiita kuti ishande zvakanaka. Zvakare, USB yakajairika, saka inoshanda nemidziyo yakawanda. Izvi zvinoita kuti zvinhu zvekubatanidza zvive nyore uye zvinoderedza kudiwa kwetambo dzakasiyana.
Kuvandudza Speed: USB 3.0 inoita kufambisa data nekukurumidza, yakanakira mafaera makuru.
Power Management: USB ports yakanaka pakubata simba, saka zvishandiso zvinogona kushanda pasina rimwe simba.
Inokodzera Mushandisi: Izvo zviri nyore plug mukati uye kunze pasina kudzima komputa.
Zvakaipa: Asi, USB ports ine zvimwe zvakaderera. Semuenzaniso, vanogona chete kuenda kure, kusiyana ne serial ports. Zvakare, kushandisa akawanda USB hubs kunogona kuita kuti masaini asina simba, achikanganisa kuita.
Hurefu Hwetambo Hupfupi: Hurefu hupfupi hwetambo dze USB hunogona kudzikisira paunogona kuisa zvishandiso.
Signal Degradation: Kushandisa hubs dzakawanda kunogona kuderedza chiratidzo, kukuvadza kuita.
Kusarudza Iyo Yakakodzera Port kune Zvaunoda
Kusarudza mhando yechiteshi ndiyo kiyi yemidziyo yako. Iwe unofanirwa kuziva zvese zvekare uye zvitsva zvinodiwa. Midziyo yenhaka inogona kuda serial ports, ichiri kushandiswa munzvimbo dzakaita seindasitiri otomatiki uye telecom.
Serial ports, kunyanya RS-232, yakanakira maturusi nemidziyo yekare. Ivo vanovimbisa kuenderana kuri pamusoro-notch.
Kune zvishandiso zvitsva, USB ports ndiyo sarudzo iri nani. Zvinokurumidza, zvakasiyana-siyana, uye zvinoshandiswa zvakanyanya. USB ports inobatanidza zvishandiso zvakawanda, kubva pakuchengetera kuenda kune zvinoratidzwa, zviri nyore.
Ivo zvakare vanoita zvekubatanidza zvishandiso zviri nyore neplug-uye-kutamba. USB maadapter anobatsira ekare serial zvishandiso kushanda neatsva USB masisitimu. Izvi zvinoita kuti shanduko iite nyore.
Kusarudza chiteshi chakakodzera zvinoenderana nezvido zvako uye tekinoroji yemudziyo. Kusanganisa zviteshi zvekare uye zvitsva zvinogona kuve zvakangwara. Tarisa maitiro nezvinodiwa zveindasitiri yako.
Nekuenzanisa madoko ako kune aya zviyero, iwe unowana kuita kwakanyanya. Iwewo unogadzirira kune ramangwana tech shanduko.
