Network media — types?
Wired (copper, fiber), wireless (radio, optical)
Ethernet standards — max length?
Typically 100 meters for 100 Mbit/s and 1 Gbit/s
Copper cable — structure?
Twisted pairs within a protective sheath, categorized by CAT levels
Network topologies — tradeoffs?
Star: high availability, single point failure; Ring: fault tolerance, complex
Structured cabling — ISO levels?
Levels include Primary, Secondary, Tertiary; organized by building components
Computer network — scope?
Interconnected devices sharing resources, services, data exchange
Wired vs wireless?
Wired uses copper/fiber; wireless transmits via radio/air
Ethernet max length?
100 meters for standard speeds, varies with standard and medium
CAT categories — purpose?
Specify performance, bandwidth, and transmission limits
Topologies — security concern?
Central points attract attacks; ring and wireless have specific risks
ISO/IEC cabling levels?
Primary, Secondary, Tertiary; connect building to devices
Network services?
DNS, DHCP, file transfer, email, video, online shopping
