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
