A yau za mu yi magana ne game da bambanci tsakanin tashar tashar jiragen ruwa da tashar jiragen ruwa. Dukansu serial port da parallel port duk hanyoyin haɗin kwamfuta ne na gama gari, waɗanda ake amfani da su wajen haɗa na'urori da kwamfutoci, amma akwai babban bambance-bambance a tsakanin su.

1. Menene madaidaicin tashar jiragen ruwa?

Parallel tashar jiragen ruwa shine gajarta na layi daya. Madaidaicin tashar jiragen ruwa na kwamfutocin masana'antu suna amfani da mahaɗa mai siffa D 25-pin. Abin da ake kira "parallel" yana nufin cewa ana watsa bayanai guda 8 a lokaci guda ta hanyar layi ɗaya, ta yadda saurin watsa bayanai ya inganta sosai, amma tsawon layin layi na layi yana da iyaka. Saboda tsayin daka yana ƙaruwa, tsangwama zai karu, kuma bayanan za su kasance masu saurin kuskure. A halin yanzu, layin layi ɗaya ana amfani da shi azaman tashar bugawa, da sauransu.

2. Menene tashar tashar jiragen ruwa?

Ana kuma kiran tashar tashar jiragen ruwa serial sadarwa interface, ko tashar COM. Dangane da ka'idodin lantarki da ka'idoji, jerin tashoshin jiragen ruwa sun haɗa da RS-232-C, RS-422, RS485, USB, da sauransu.

3. Menene bambanci tsakanin su biyun?

1. Serial ports da parallel ports amfani hanyoyi daban-daban don watsa bayanai. Serial port shine hanyar sadarwa ta bit-by-bit wanda ke aikawa da bayanai zuwa kwamfuta ko wata na'ura bit by bit. Wannan hanya na iya tabbatar da amincin watsa bayanai, amma saurin watsawa yana jinkirin. Tashar tashar layi ɗaya ce ta hanyar sadarwa mai kama da juna wacce za ta iya aika bayanai da yawa a lokaci guda, don haka saurin watsawa yana da sauri, amma tsangwama yana shafar shi cikin sauƙi.

2. Serial ports da parallel ports suma daban-daban a cikin na'urori da yanayin da ake amfani da su. Ana amfani da serial ports don haɗa wasu na'urori marasa sauri, kamar printer, modem, da dai sauransu. Gudun watsa bayanansu ba su da yawa, amma ana buƙatar amincin watsa bayanai ya kasance mai girma. Yawanci ana amfani da tashoshi na layi ɗaya don haɗa na'urori masu sauri, irin su hard drives, na'urorin gani da sauransu, waɗanda ke buƙatar saurin watsawa da yawa da watsa bayanai, amma suna da ƙananan buƙatu don amincin watsa bayanai.

3. The musaya na zahiri na serial ports da parallel ports suma sun bambanta. Serial tashoshin jiragen ruwa yawanci amfani da DB9 ko DB25 musaya, yayin da layi daya tashar jiragen ruwa amfani da DB25 musaya ko a layi daya tashar fil fil. Bugu da kari, serial ports kuma iya amfani da kebul musaya don watsa bayanai.

4. Kammalawa

Akwai manyan bambance-bambance tsakanin tashoshin jiragen ruwa na jeri-da-gidanka da tashoshi masu kama da juna dangane da hanyoyin watsa bayanai, yanayin amfani, da mu'amalar jiki. Sabili da haka, lokacin zabar mai dubawa, kuna buƙatar zaɓar ƙirar da ta dace bisa takamaiman buƙatun aikace-aikacen.

Na baya: Yadda ake ƙarawa da sarrafa saurin CPU?

Na gaba: Cikakkun kwamfutocin masana'antu suna taka muhimmiyar rawa wajen hazakar manyan motocin da ke tashar jiragen ruwa
