      Iyini i-Diode? [Kuchazile]

      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 ...

      Ukuqonda Kokuqala Kwe-LAN

      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 ...

      Kuyini ukushintshwa kwe-Ethernet futhi kusebenza kanjani?

      Ngokuthuthuka okusheshayo kwamakhompiyutha kanye nobuchwepheshe bawo bokuxhumanisa (okwaziwa nangokuthi “ubuchwepheshe benethiwekhi”), i-Ethernet isiphenduke inethiwekhi yekhompiyutha enezingqimba ezimbili enebanga eliphakeme kakhulu lokungena kuze kube manje. Ingxenye eyinhloko ye-Ethernet iswishi ye-Ethernet. Imanuwali kanye...

      Iyini i-VCSEL laser?

      I-VCSEL, ebizwa ngokuthi i-Vertical Cavity Surface Emitting Laser ngokugcwele, iwuhlobo lwe-semiconductor laser. Okwamanje, ama-VCSEL amaningi asekelwe kuma-semiconductors e-GaAs, futhi ubude be-wavelength bokukhishwa ikakhulukazi bukwibhendi ye-infrared wave. Ngo-1977, uProfesa Ika Kenichi waseTokyo University of Technology ...

      Ukuhlukaniswa Kwenethiwekhi ye-PAN, LAN, MAN kanye ne-WAN

      Inethiwekhi ingahlukaniswa nge-LAN, LAN, MAN, kanye ne-WAN. Izincazelo ezithile zala mabizo ziyachazwa futhi ziqhathaniswe ngezansi. (1) Inethiwekhi yendawo yomuntu siqu (i-PAN) Amanethiwekhi anjalo anganika amandla ukuxhumana kwenethiwekhi yebanga elifushane phakathi kwezinto ezisetshenziswayo eziphathwayo namadivayisi okuxhumana, Lokhu kuhlanganisa...

      Siyini Inkomba Yamandla Esiginali Etholiwe (RSSI) ngokuningiliziwe

      I-RSSI isifinyezo se-Received Signal Strength Indication. Isici samandla esignali esamukelwe sibalwa ngokuqhathanisa amanani amabili; okungukuthi, ingasetshenziswa ukunquma ukuthi amandla esiginali aqine noma abuthakathaka kangakanani uma eqhathaniswa nenye isignali. Ifomula yokubala ye-RSSI...
