Study Notes

Internet Groups

IETF, ICANN, and IAB are groups that ensure Internet structure
Intranets are internal networks accessible only to authorized members
Extranets provide secure network access to external individuals
Broadband cable, DSL, wireless WANs, and mobile services are popular home and small office Internet connections
Business DSL, leased lines, and Metro Ethernet are business-class interconnections
Cable services offer high bandwidth and are always on
Shell, kernel, and hardware are components of a computer's operating system
GUIs are user-friendly but can fail, so CLI is usually used for network devices
Console and SSH are access methods for devices
Network communications depend on end user device interfaces, networking device interfaces, and cables
IP address configuration can be manual or automatic using DHCP
TCP/IP is the most common protocol suite, maintained by IETF
OSI is a protocol suite developed by ISO and ITU
AppleTalk and Novell NetWare are proprietary protocol suites
TCP/IP, Ethernet, and WLAN are common protocols in the network access layer
TCP/IP includes many different protocols
OSI divides the network access and application layers of TCP/IP into multiple layers
OSI Layers 1 and 2 focus on media access and physical data transmission
Segmenting breaks messages into smaller units for speed and efficiency
Multiplexing interleaves multiple data streams
Sequencing numbers segments for reassembly at the destination
Encapsulation is the process where protocols add information to data
PDUs (Protocol Data Units) change names based on their function during encapsulation

Protocol Suites

Protocol suites are groups of interrelated protocols for communication functions
Higher layers are concerned with data processing and presentation
Lower layers handle data movement and provide services to higher layers

Internet Connections

Internet access technologies are methods for connecting users and organizations to the internet
