Amaza okukhanya ayimisebe ye-electromagnetic ekhiqizwa ama-electron ngesikhathi sokunyakaza kwe-athomu. Ukunyakaza kwama-electron kuma-athomu ezinto ezihlukahlukene kuhlukile, ngakho amaza okukhanya awakhiphayo nawo ahlukile. I-Spectrum iyiphethini yokukhanya kwe-monochromatic ehlukaniswe uhlelo lokuhlakazeka (...

Incazelo yomqondo: I-Ethernet iyindinganiso evamile yokuxhumana esetshenziswa yi-LAN ekhona. Inethiwekhi ye-Ethernet isebenzisa ubuchwepheshe be-CSMA/CD (Carrier Sense Multiple Access and Conflict Detection) . I-Ethernet ibusa ubuchwepheshe be-LAN: 1. Izindleko eziphansi (ngaphansi kwemoto yenethiwekhi ye-Ethernet eyi-100...

Indlela yokufinyelela nokulawula amadivaysi ekhompyutha ahlukene ngokusebenzisa imidiya ku-LAN iqondwa kanje. Kudala, i-Ethernet yayisetshenziswa ukuxhuma yonke imigqa yamakhompyutha asekhaya ebhasini ukuze kuqhamuke ukuxhumana kwamakhompyutha. Uma usebenzisa le ndlela ukuthumela idatha, udinga...

1, Izinga lokushisa lokusebenza Izinga lokushisa lokusebenza lemojula yokubona. Lapha, izinga lokushisa libhekisela ekushiseni kwezindlu. Kunamazinga okushisa amathathu okusebenza we-module optical, izinga lokushisa lokuhweba: 0-70 ℃; Izinga lokushisa lezimboni: – 40 ℃ – 85 ℃; Kukhona futhi i-exp...

I-Diode yakhiwe ukuhlangana kwe-PN, futhi i-photodiode ingakwazi ukuguqula isignali ye-optical ibe isignali kagesi, njengoba kuboniswe ngezansi: Ngokuvamile, i-covalent bond i-ionized lapho i-PN junction ikhanyiswa ngokukhanya. Lokhu kudala izimbobo kanye namapheya e-electron. I-photocurrent yenziwe ngenxa ...

I-LAN ithandwa kakhulu esiyisebenzisayo namuhla. Yini i-LAN? I-Local Area Network (LAN) ibhekisela eqenjini lamakhompyutha axhunywe amakhompyutha amaningi endaweni ethile asebenzisa isiteshi sokusakaza. Uma kuningi kule ndawo, kulapho amadivaysi amaningi akwazi ukuxhumana. Futhi kuphela ...
