Amaza okukhanya yimitha ye-electromagnetic eveliswa zii-electron kwinkqubo yentshukumo yeathom. Ukushukuma kwee-electron kwiiathom zezinto ezahlukeneyo kwahlukile, ngoko ke amaza okukhanya eziwakhuphayo nawo ahlukile. I-Spectrum yipateni yokukhanya kwe-monochromatic eyahlulwe yinkqubo yokusasazwa (...

Inkcazo yengqiqo: I-Ethernet ngowona mgangatho wonxibelelwano uqhelekileyo owamkelwa yiLAN ekhoyo. Inethiwekhi ye-Ethernet isebenzisa i-CSMA / CD (i-Carrier Sense Access Multiple Access kunye ne-Conflict Detection) ubuchwepheshe. I-Ethernet ilawula iteknoloji ye-LAN: 1. Ixabiso eliphantsi (ngaphantsi kwe-100 yenethiwekhi ye-Ethernet imoto...

Indlela yokufikelela kunye nokulawula izixhobo ezahlukeneyo zekhompyuter ngokusebenzisa imidiya kwi-LAN iqondwa ngolu hlobo lulandelayo. Kwakudala, i-Ethernet yayisetyenziselwa ukudibanisa yonke imigca yeekhompyuter zekhaya kwibhasi ukuqonda unxibelelwano oludibeneyo lweekhompyuter. Xa usebenzisa le ndlela yokuthumela idatha, kufuneka...

1、 Ubushushu bokusebenza Ubushushu bokusebenza bemodyuli yokubona. Apha, iqondo lobushushu libhekisa kubushushu bendlu. Kukho amaqondo okushisa amathathu okusebenza kwemodyuli ye-optical, ukushisa kwezorhwebo: 0-70 ℃; Ubushushu bemizi-mveliso: – 40 ℃ – 85 ℃; Kukho kwakhona i-exp ...

I-Diode yenziwe nge-PN junction, kwaye i-photodiode inokuguqula isignali ye-optical ibe ngumqondiso wombane, njengoko kuboniswe ngezantsi: Ngokuqhelekileyo, i-covalent bond i-ionized xa i-PN junction ikhanya ngokukhanya. Oku kudala imingxunya kunye neeperi electron. Ifotocurrent yenziwe ngenxa...

I-LAN yeyona nto idumileyo siyisebenzisa namhlanje. Yintoni iLAN? Inethiwekhi yeNdawo yeNgingqi (LAN) ibhekisa kwiqela leekhompyuter ezidityaniswe ziikhompyuter ezininzi kwindawo ethile zisebenzisa ijelo losasazo. Okukhona kukho kule ndawo, kokukhona izixhobo ezikwaziyo ukunxibelelana omnye komnye. Kwaye kuphela ...
