Diode imapangidwa ndi mgwirizano wa PN, ndipo photodiode imatha kusintha chizindikiro cha kuwala kukhala chizindikiro cha magetsi, monga momwe tawonetsera pansipa: Kawirikawiri, mgwirizano wa covalent umapangidwa ndi ionized pamene mgwirizano wa PN umawunikiridwa ndi kuwala. Izi zimapanga mabowo ndi ma electron awiriawiri. Photocurrent imapangidwa chifukwa cha ...

LAN ndiyo yotchuka kwambiri yomwe timagwiritsa ntchito masiku ano. LAN ndi chiyani? A Local Area Network (LAN) amatanthauza gulu la makompyuta olumikizidwa ndi makompyuta angapo mdera lina pogwiritsa ntchito njira yowulutsira. Pamene pali zambiri m'derali, zipangizo zambiri zomwe zimatha kulankhulana. Ndipo kokha ...

Ndi chitukuko chofulumira cha makompyuta ndi teknoloji yawo yolumikizirana (yomwe imatchedwanso "teknoloji yapaintaneti"), Ethernet yakhala makina apakompyuta afupikitsa awiri omwe ali ndi chiwerengero chapamwamba kwambiri mpaka pano. Chigawo chapakati cha Ethernet ndi Ethernet switch. Manual ndi ...

VCSEL, yomwe imatchedwa kuti Vertical Cavity Surface Emitting Laser kwathunthu, ndi mtundu wa laser semiconductor. Pakalipano, ma VCSEL ambiri amachokera ku ma semiconductors a GaAs, ndipo kutalika kwa mafunde kumakhala mu bandi ya infrared wave. Mu 1977, Pulofesa Ika Kenichi wa Tokyo University of Technology ...

Maukonde amatha kugawidwa mu LAN, LAN, MAN, ndi WAN. Matanthauzo enieni a mainawa akufotokozedwa ndikufanizidwa pansipa. (1) Personal Area Network (PAN) Maukonde oterowo amatha kulumikizana ndi ma netiweki apatali pakati pa zida zonyamulika ndi zida zoyankhulirana, Cov ...

RSSI ndiye chidule cha Received Signal Strength Indication. Chidziwitso champhamvu champhamvu cholandilidwa chimawerengedwa poyerekezera zikhalidwe ziwiri; ndiko kuti, angagwiritsidwe ntchito kudziwa kuti mphamvu ya chizindikirocho ndi yolimba kapena yofooka bwanji poyerekeza ndi chizindikiro china. Njira yowerengera ya RSSI...
