Personal Area Network (PAN) - answer-- Provides communication for devices
owned by a single user that work over a short distance
- Bluetooth, IR, NFC, etc.
(1.1 & 2.7)
PoE (Power over Ethernet) - answer-Devices that send Ethernet data and
power over twisted-pair cable to compliant devices (for example, cameras,
phones, etc).
(2.2)
Modem - answer-- Cable Version: Uses DOCSIS (Data over Cable Service
Interface Specification) which is broadband.
,- DSL Version: Uses ADSL (Asymmetrical Digital Subscriber Line) where
download speed is higher than upload speed.
(2.2)
ONT (optical network terminal) - answer-- Fiber
- ISP fiber line stretches to demarc point at which your in-home copper wire
takes over.
(2.2)
NIC (Network Interface Card) - answer-- A device that serves as an interface
between the computer and the network. Also called a network adapter or
network card.
- Ethernet Connection
- May need drivers installed before hardware is installed (Check Manual)

- 128 bits or 16 bytes -> 16 bits per number
APIPA (Automatic Private IP Addressing) - answer-- Link Local addresses (no
router forwarding)
- IETF has reserved 169.254.0.0 - 169.254.255.255
- Only communicates on your network
(2.5)
Static IP - answer-- An IP address that is manually assigned to a device and
remains constant until it is manually changed.
(2.5)
Dynamic IP - answer-- IP address assigned by DHCP server.
- This method insures there are no overlapping IP addresses within a network.
- Changes when lease expires
(2.5)
Gateway - answer-- A node that handles communication between its LAN and
other networks.
(2.5)
DNS Configuration - answer-- 13 root server clusters (Over 1,000 actual
servers)
- 100's of Generic Top Level Domains (gTLD)
