Masaisai emwenje ndiwo mwaranzi wemagetsi anogadzirwa nemaerekitironi mukufamba kweatomu. Kufamba kwemaerekitironi mumaatomu ezvinhu zvakasiyana kwakasiyana, saka masaisai echiedza aanoburitsa akasiyanawo. Spectrum ndiyo patani yechiedza chemonochromatic yakaparadzaniswa nedhisheni system (...

Tsananguro yepfungwa: Ethernet ndiyo yakajairika yekutaurirana protocol standard yakatorwa neLAN iripo. Iyo Ethernet network inoshandisa CSMA/CD (Carrier Sense Multiple Access uye Conflict Detection) matekinoroji. Ethernet inotonga matekinoroji eLAN: 1. Mutengo wakaderera (pasi pe100 Ethernet network mota...

Maitiro ekuwana nekudzora akasiyana komputa zvishandiso kuburikidza ne media muLAN inofanonzwisiswa sezvinotevera. Kare kare, Ethernet yaishandiswa kubatanidza mitsara yese yemakomputa epamba kubhazi kuona kutaurirana kwemakomputa. Paunenge uchishandisa nzira iyi kutumira data, unofanirwa...
