1 – LABORATORIYA ISHI
TARMOQ QURILMALARIDA DASTLABKI XAVFSIZLIK SOZLAMALARINI O’RNATISH
Ishdan maqsad : Kommutator qurilmasining tuzilishi, ishlash tamoyillari, masofadan kirishni ta’minlash usullari hamda xavfsizlik ko’rsatkichlarini sozlash qoidalarini tadqiq qilishdan iborat.
Ushbu laboratoriya ishida 1.1 – rasmda keltirilgan tarmoq tuzilishi bo`yicha konfiguratsiya ishlari amalga oshiriladi.
