Kodi pali kusiyana kotani pakati pa ma serial ports ndi ma parallel ports?
Lero tikambirana za kusiyana pakati pa serial port ndi parallel port. Ma doko onse awiri ndi doko lofananira ndizomwe zimagwiritsidwa ntchito pakompyuta, zomwe zimagwiritsidwa ntchito kulumikiza zida ndi makompyuta, koma pali kusiyana kwakukulu pakati pawo.
M'ndandanda wazopezekamo
- 1. Kodi doko lofananira ndi chiyani?
- 2. Kodi serial port ndi chiyani?
- 3. Kodi pali kusiyana kotani pakati pa ziwirizi?
- 4. Mapeto
1. Kodi doko lofananira ndi chiyani?
Parallel doko ndiye chidule cha mawonekedwe ofanana. Doko lofananira la makompyuta am'mafakitale limagwiritsa ntchito cholumikizira cha mapini 25 ngati D. Zomwe zimatchedwa "parallel" zimatanthawuza kuti ma bits 8 a data amafalitsidwa nthawi imodzi kupyolera mu mizere yofanana, kotero kuti liwiro la kufalitsa deta likuyenda bwino kwambiri, koma kutalika kwa mzere wa kufalitsa kofanana kumakhala kochepa. Chifukwa kutalika kumawonjezeka, kusokoneza kudzawonjezeka, ndipo deta idzakhala yolakwika. Pakali pano, mawonekedwe ofanana amagwiritsidwa ntchito ngati chosindikizira, etc.
2. Kodi serial port ndi chiyani?
Doko la serial limatchedwanso serial communication interface, kapena COM port. Malinga ndi miyezo yamagetsi ndi ma protocol, ma serial madoko akuphatikizapo RS-232-C, RS-422, RS485, USB, etc.
3. Kodi pali kusiyana kotani pakati pa ziwirizi?
1. Madoko a seri ndi ma doko ofananira amagwiritsidwa ntchito njira zosiyanasiyana zotumizira deta. Doko la serial ndi mawonekedwe opatsirana pang'ono-pang'ono omwe amatumiza deta ku kompyuta kapena chipangizo china pang'onopang'ono. Njirayi imatha kutsimikizira kudalirika kwa kufalitsa kwa data, koma kuthamanga kwapaulendo kumachepera. Doko lofananira ndi mawonekedwe opatsirana omwe amatha kutumiza ma data angapo nthawi imodzi, kotero kuti liwiro lotumizira limayenda mwachangu, koma limakhudzidwa mosavuta ndi kusokoneza.
2. Siri madoko ndi madoko ofanana nawonso zosiyana pazida ndi zochitika zomwe zimagwiritsidwa ntchito. madoko siriyo zambiri ntchito kulumikiza ena otsika-liwiro zipangizo, monga osindikiza, modemu, etc. deta yawo kufala liwiro si mkulu, koma kudalirika kwa kufala deta chofunika kukhala mkulu. Madoko ofananira nthawi zambiri amagwiritsidwa ntchito kulumikiza zida zothamanga kwambiri, monga ma hard drive, ma drive owoneka bwino, ndi zina zambiri, zomwe zimafuna kuthamanga kwapang'onopang'ono komanso kutumizirana ma data ambiri, koma zimakhala ndi zofunikira zochepa zodalirika pakutumiza kwa data.
3. The mawonekedwe akuthupi ma serial madoko ndi ma doko ofanana ndi osiyana. Ma doko a seri nthawi zambiri amagwiritsa ntchito DB9 kapena DB25 zolumikizira, pomwe madoko ofananira amagwiritsa ntchito ma DB25 kapena zikhomo zofananira. Kuphatikiza apo, ma serial madoko amathanso kugwiritsa ntchito mawonekedwe a USB potumiza deta.
4. Mapeto
Pali kusiyana kwakukulu pakati pa ma serial ports ndi ma doko ofanana potengera njira zotumizira deta, mawonekedwe ogwiritsira ntchito, ndi mawonekedwe akuthupi. Choncho, posankha mawonekedwe, muyenera kusankha mawonekedwe oyenera malinga ndi zofunikira za ntchito.
