Study Notes
Network Devices and Topologies
- Nodes/Hosts: Devices communicating on a network
- Network Interface: Converts digital data to signals for transmission
- Peer-to-Peer (P2P) Network: Hosts share resources, simple to implement, but difficult to manage and secure as network size increases
- Client-Server Network: Servers provide resources, clients consume, scalable, centralized easier to manage and secure compared to P2P
- LAN (Local Area Network): Network within a building or organization
- MAN (Metropolitan Area Network): Network connecting devices across a city
- WAN (Wide Area Network): Network connecting multiple smaller networks
Network Types
- Network: Connected devices under one organization's control
- Internetwork: Two separate networks connected, not under one organization
- Internet: Collection of interconnected networks under many organizations
- Intranet: Private, internal version of the Internet.
- Extranet: Partially accessible to entities outside the organization
Network Topologies
- Physical Topology: Layout of network connections
- Logical Topology: How devices communicate
- Bus Topology: Single connection link
- Ring Topology: Devices connected in a ring
- Mesh Topology: Every device connected to every other device
- Star Topology: Devices connected to a central device
- Partial Mesh Topology: Some devices connected to all devices, some to only a few devices
Data Link Layer
- Logical Link Control (LLC) Sublayer: Layer 2 of OSI, manages interface between upper and lower layers
- Protocol Data Units (PDUs): Units of data at different layers (Bits, Frames, Packets, Segments)
Network Protocols and Services
- Authorization and Authentication: Layer 5 Session layer protocol
- WLAN (Wireless Local Area Network): Uses radio waves
- SAN (Storage Area Network): High-speed network for storage access (block-level)
- NAS (Network Attached Storage): File-level storage, acts as a server
- SD-WAN (Software Defined WAN): Software manages a WAN
- MPLS (Multiprotocol Label Switching): Assigns labels for efficient routing
- ARP (Address Resolution Protocol): Maps IP addresses to MAC addresses
- TCP Handshake: (SYN, SYN-ACK, FIN) process for establishing connections
- ICMP (Internet Control Message Protocol): Checks network reachability (Ping)
- IGMP (Internet Group Management Protocol): Allows single packets to reach multiple hosts
Cabling
- Solid Wire: Better signal conduction but less flexible
- Stranded Wire: More flexible but less reliable
- UTP (Unshielded Twisted Pair): Inexpensive, common cable for Ethernet, telephone. (CAT 5-8 vary in speed and length limitations)
- Coaxial Cable: Resistance to interference, good for cable TV, and ethernet in some cases
- Fiber Optic Cable: Uses light to transmit data, high speed, low signal loss, but high cost single-mode better for distances more than 100km +
Wireless Standards
- 802.11g, a, b, n, ac, ax: Varying speeds and frequencies for wireless
Cable Connectors
- BNC: Bayonet mount for coaxial cable
- F-Type: For cable TV and satellite TV
- RJ-45: For twisted-pair networks (Ethernet)
- Fiber Optic Connectors: LC, ST, SC, MT-RJ
Network Addressing and Configuration
- Private IP Addressing (RFC 1918): Addresses for use on private networks (10.x.x.x, 172.16.0.0 to 172.31.255.255, 192.168.0.0 to 192.168.255.255)
- Link-local: Communication within the network
- IPv6 transition to IPv4: Methods like 6to4, Teredo
- IPv4 transition to IPv6: Methods like 4to6
- DHCP (Dynamic Host Configuration Protocol): Automatically assigns IP addresses
DHCP Servers and Agents
- DHCP Scope: Defines IP configuration parameters
- DHCP Relay Agent: Forwards DHCP requests when the server isn't on the local network
- DHCP Helper: Forwards DHCP broadcasts to the DHCP Server
Other Network Devices and Concepts
- Transceiver: Device allowing link between interfaces
Wiring Standards
- T568A/T568B: Wiring standards for twisted-pair cables.
- Punchdown Block: Organizes wiring
- Patch Panel: Connects wires to patch cords
- Gigabit Interface Converter (GBIC): Connects network devices to fiber optics
- SFP (Small Form-factor Pluggable): Smaller, hot-swappable interface than GBIC
- QSFP (Quad SFP): Higher data rate interface
