Networking Concepts and Protocols Quiz

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
