    Study Notes

    ARP (Address Resolution Protocol)

    • Maps IP addresses to MAC addresses on a local network

    Routing

    • Determines the path data takes across multiple networks to reach its destination

    Decentralized Routing

    • Each router makes its own decisions based on local information
    • Works well for large networks due to adaptability and no single point of failure
    • Example: The internet

    Centralized Routing

    • One central node makes all routing decisions
    • Easier to manage but can cause problems if the central node fails
    • Example: Some small private networks

    Connectionless Messaging

    • Data sent without establishing a connection
    • Faster but messages might get lost or arrive in the wrong order
    • Example: UDP used for online games or video streaming

    Connection-Oriented Messaging

    • Connection established before sending data, ensuring delivery
    • More reliable but slower
    • Example: TCP used for web browsing and downloading files

    Session

    • Temporary connection between two devices for data exchange

    DNS uses UDP because:

    • Speed: Doesn't need to wait to establish a connection
    • Less overhead: Simpler and faster since it doesn't check for errors or establish a connection

    Static Routing

    • Routes manually configured and remain fixed unless updated
    • Best for small networks with predictable traffic patterns
    • Reliable because routes stay the same

    Dynamic Routing

    • Routes update automatically based on network conditions
    • Efficient for larger, dynamic networks
    • More complex due to routers communicating to update routes

    Routing types used by Clients and Gateways

    • TCP/IP Client: Uses unicast routing to send data to a specific recipient
    • TCP/IP Gateway: Uses routing protocols like OSPF or BGP to determine the best path for data across networks

    TCP/IP Network Layers

    • Application Layer Address: Identifies applications within a host, often using port numbers
    • Data Link Layer Address: Hardware or physical address that uniquely identifies a device within a local network, such as a MAC address
    • Network Layer Address: A logical address that identifies a device on a network, such as an IP address

    Other Key Terms

    • Authoritative Name Server: Provides definitive answers for domain name queries
    • ARP Cache: Temporarily stores recently resolved IP-to-MAC address mappings
    • Automatic Repeat reQuest (ARQ): Error control method using acknowledgments and timeouts for reliable data transfer
    • Autonomous System: Collection of IP networks and routers under a single organization
    • Auxiliary Port: Secondary port for management and maintenance
    • Border Gateway Protocol (BGP): Used for routing between autonomous systems on the internet
    • Border Router: Connects an autonomous system to external networks
    • Broadcast Message: Sent to all devices within a specific network segment
    • Cisco Internetwork Operating System (IOS): Proprietary operating system used by Cisco devices
    • Classless Addressing: IP addressing scheme using variable-length subnet masking
    • Console Port: Physical port for direct access to manage and configure network devices
    • Continuous ARQ: Continuously transmits data and retransmits only erroneous frames
    • Designated Router: Elected in certain routing protocols to minimize routing traffic
    • Destination Port Address: Identifier used to direct data to a specific service or application
    • Distance Vector Dynamic Routing: Shares information about the distance to reach destinations
    • Domain Name Service (DNS): Hierarchical naming system for translating domain names to IP addresses
    • Dynamic Addressing: Assigns IP addresses automatically
    • Dynamic Host Configuration Protocol (DHCP): Assigns IP addresses and network configurations
    • Dynamic Routing: Adjusts the paths data takes based on network conditions
    • Enhanced Interior Gateway Routing Protocol (EIGRP): Cisco-developed routing protocol combining features of distance-vector and link-state protocols
    • Exterior Routing Protocol: Exchanges routing information between different autonomous systems
    • Flow Control: Manages the rate of data transmission
    • Gateway: Connects different networks and translates protocols
    • Go-Back-N ARQ: Retransmits all subsequent frames if an error is detected
    • Hop: Journey data takes from one router to another
    • Interface: Point of interaction between systems or devices
    • Interior Gateway Routing Protocol (IGRP): Developed by Cisco for routing within an autonomous system
    • Internet Address Classes: Classification of IP addresses by network size
    • Internet Control Message Protocol (ICMP): For sending error messages and operational information about IP network connections
    • Internet Corporation for Assigned Names and Numbers (ICANN): Coordinates IP address assignment and domain name management
    • Internet Group Management Protocol (IGMP): Manages device membership in multicast groups

    Access Point (AP)

    • Allows wireless devices to connect to a wired network using Wi-Fi
