Chii chinonzi IO Card?

Munyika yanhasi inofambiswa nedata, I/O makadhi- pfupi ye Makadhi ekupinda/zvekuburitsa-ita basa rakakosha mukubatanidza makomputa nemidziyo yekunze. Ingave muhofisi PC kana indasitiri yekudzora system, izvi makadhi okuwedzera ipai mainterface anodiwa ekutaurirana nawo peripherals, sensors, uye michina.

An I/O kadhi imhando ye interface kadhi yakaiswa mumakombuta kuwedzera slot (zvakaita se PCI, PCIe, kana USB) iyo inogonesa iyo system kuita kutumira uye kugamuchira data kuenda/kubva kumidziyo yekunze. Izvi zvinogona kusanganisira printers, network zvishandiso, maindasitiri sensors, kana robhoti maoko. Funga nezvayo semuturikiri anoshandura masaini kubva kunyika yenyama kuenda kudhijitari data iyo komputa inogona kunzwisisa-uye zvakasiyana.

Mukushanda kwemaindasitiri, I/O makadhi zvakakosha kune muchina otomatiki, maitiro ekudzora, uye kutora data. Kubva digital uye analogi I/O ku motion control uye makadhi ekukurukurirana, kusiyana-siyana kweI / O mhinduro inobvumira mabhizimisi kuti scale, gadzirisa,uye optimize mabasa.

Sekuda kwe real-time monitoring, kuwana kure,uye kugadzirwa kwakangwara inowedzera, kunzwisisa kuti kadhi reI/O chii-uye zvarinoita-zvave zvakakosha kune vanobatanidza masisitimu, mainjiniya, uye kunyangwe nyanzvi dzeIT dzinobata nharaunda dzemakomputa dzazvino.

II. Kunzwisisa Kupinza / Kubuda muComputing

Papakati pese computing system ndiyo pfungwa ye Kupinza/Kubuda (I/O)-yakakosha nzira inobvumira komputa kuita dyidzana nemidziyo yekunze. Kungotaura, input idata rakagamuchirwa nehurongwa (semuenzaniso, kubva a keyboard, sensor, kana scanner), apo output idata inotumirwa kubva kune system kuenda kune zvishandiso senge a monitor, actuator, kana printer.

I/O haisi yekungobatanidza Hardware; inotsanangura kuti sei data inoyerera pakati peCPU nenyika yekunze. Izvi zvinosanganisira zvese kubva pakudyidzana kwevashandisi kusvika kudzora muchina munzvimbo dzemaindasitiri. Pasina I/O inoshanda, kunyangwe komputa ine simba kwazvo yaizove yega uye isingaite.

III. Chii chinonzi IO Card?

An I/O kadhi- pfupi ye Input/Output card- inyanzvi kadhi rekuwedzera iyo inobvumira komputa kana indasitiri system kuti interface nemidziyo yekunze.
