Apa bedane antarane port serial lan port paralel?

27-09-2024 09:02:48

Dina iki kita bakal ngomong babagan prabédan antarane port serial lan port paralel. Loro-lorone port serial lan port podo antarmuka komputer umum, kang digunakake kanggo nyambungake piranti lan komputer, nanging ana beda gedhe antarane wong-wong mau.

1. Apa port paralel?

Port paralel minangka singkatan saka antarmuka paralel. Port paralel komputer industri nggunakake konektor D-shaped 25-pin. Sing disebut "paralel" tegese 8 bit data sing ditularaké bebarengan liwat garis podo, supaya kacepetan transmisi data nemen apik, nanging dawa baris transmisi podo winates. Amarga dawa mundhak, gangguan bakal nambah, lan data bakal rawan kasalahan. Saiki, antarmuka paralel utamane digunakake minangka port printer, lsp.

2. Apa port serial?

Port serial uga disebut antarmuka komunikasi serial, utawa port COM. Miturut standar lan protokol listrik, port serial kalebu RS-232-C, RS-422, RS485, USB, lsp.

3. Apa bedane loro?

1. bandar Serial lan bandar podo nggunakake macem-macem cara kanggo ngirim data. Port serial minangka antarmuka transmisi bit-by-bit sing ngirim data menyang komputer utawa piranti liyane kanthi dicokot. Cara iki bisa njamin linuwih transmisi data, nanging kacepetan transmisi alon. Port paralel minangka antarmuka transmisi paralel sing bisa ngirim sawetara bit data ing wektu sing padha, saéngga kacepetan transmisi luwih cepet, nanging gampang kena gangguan.

2. bandar Serial lan bandar podo uga beda ing piranti lan skenario sing digunakake. Port serial biasane digunakake kanggo nyambungake sawetara piranti kacepetan kurang, kayata printer, modem, etc. Kacepetan transmisi data ora dhuwur, nanging linuwih transmisi data kudu dhuwur. Port paralel biasane digunakake kanggo nyambungake piranti kanthi kacepetan dhuwur, kayata hard drive, drive optik, lan sapiturute, sing mbutuhake kecepatan transmisi sing luwih dhuwur lan transmisi data sing akeh, nanging nduweni syarat sing luwih murah kanggo linuwih transmisi data.

3. Ing antarmuka fisik saka bandar serial lan bandar podo uga beda. Port serial biasane nggunakake antarmuka DB9 utawa DB25, nalika port paralel nggunakake antarmuka DB25 utawa pin port paralel. Kajaba iku, port serial uga bisa nggunakake antarmuka USB kanggo transmisi data.

4. Kesimpulan

Ana bedane gedhe antarane port serial lan port paralel babagan cara transmisi data, skenario panggunaan, lan antarmuka fisik. Mulane, nalika milih antarmuka, sampeyan kudu milih antarmuka sing cocog adhedhasar syarat aplikasi tartamtu.
