  • 1. Hálózatok konfigurálása Bevezetés (mit és hogyan állítsak, hogy elérjem az Internetet otthon)
  • 2. OSI és az Internet
  • 3. TCP/IP protokoll architektúra
  • 4. Microsoft Network Protokoll Architektúra
  • 5. Dokumentáció, információ, help

  • 6. Hálózat konfigurálása
    • Network Access:
      • általában automatikus
    • Internetwork:
      • manuális
      • DHCP (Dynamis Host Configuration)
    • Host to Host és felette:
      • igény szerint… most nem foglalkozunk vele
  • 7. Tipikus „Network access” otthon:
    • Telefon modem (PPP)
    • ADSL (PPPoE)
    • Cable modem
    • MicroWave, Wireless
    • IrDA, Bluetooth
    • Ethernet (Coax, UTP)
    • Egyéb más megoldások
  • 8. Fontosabb hálózati parancsok
    • ipconfig, ifconfig,
    • ping,
    • traceroute, tracert,
    • route,
    • nslookup, host,
    • arp,
    • NET (Windows NT, 2K, stb.)
    • grafikus adminisztrátori programok
