Karteikarten: Fundamentals of Computer Networking — 12 Karten

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
