Network Protocols and Concepts Quiz

Network Protocols and Concepts

• Address Resolution Protocol (ARP): Maps IP addresses to MAC addresses within a local network, essential for Ethernet communication.
• Ad Hoc Mode: A wireless network where devices connect directly without a central access point, used for small peer-to-peer networks.
• Application Layer: The top layer of the OSI model, handling network services like email (SMTP) and file transfers (FTP, HTTP).
• Authoritative Domain Name Server (DNS): Stores definitive IP address information for a domain, ensuring accurate domain resolution.
• Best-Effort Delivery Service: A network service delivering packets without guarantees of delivery or quality, used in basic data transmission.
• Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA): A protocol avoiding collisions in wireless networks, common in Wi-Fi (802.11).
• Carrier Sense Multiple Access with Collision Detection (CSMA/CD): A protocol for detecting and managing collisions in Ethernet networks for shared media.
• Colon-Hexadecimal Notation: The format for representing IPv6 addresses (e.g., 2001:0db8::1).
• Connection-Oriented Service: A communication service establishing a connection before transferring data, like TCP for reliable delivery.
• Country-Code Top-Level Domain (ccTLD): Domain extensions representing countries (e.g., .us, .uk, .jp), used for regional websites and localization.
• Data Link Layer: The OSI layer handling node-to-node data transfer, including Ethernet and Wi-Fi, managing MAC addressing.
• Differentiated Service (DS): A technique prioritizing network traffic by QoS needs, used in VoIP and video streaming.
• DNS Root Server: Top-level DNS servers directing queries to appropriate TLD servers, fundamental to the Internet's hierarchical structure.
• Domain Name System (DNS): Translates human-readable domain names into IP addresses, essential for website and email access.
• Dynamic Address: A temporarily assigned IP address by a DHCP server, common in home networks.
• Dynamic Host Configuration Protocol (DHCP): Dynamically assigns IP addresses to devices, simplifying network configuration.
• Electronic Signature: A digital signature verifying the authenticity of electronic documents.
• Fragment: A portion of a larger packet divided for transmission, necessary for networks with size limitations.
• Frame (Ethernet Packet): A unit of data encapsulated at the data link layer, containing headers, trailers for addressing and error-checking in Ethernet networks.
• Frame Relay: A WAN technology for transmitting data frames, used in connecting geographically dispersed LANs.
• Generic Top-Level Domain (gTLD): General domain extensions (e.g., .com, .org, .net).
• Handoff: Transferring a mobile connection between access points, vital in cellular networks.
• Handshaking: A process where devices establish a connection and agree on communication parameters, common in protocols like TCP.
• Infrastructure Mode: A wireless network mode where devices connect through a central access point, used in home and corporate Wi-Fi.
• Internet Control Message Protocol (ICMP): Sends diagnostic messages in IP networks (used in ping and traceroute).
• Internetworking Layer: Another term for the network layer in the OSI model, responsible for routing packets between networks.
• IP Address: A unique numerical identifier for a device on a network, essential for routing data packets.
• IP Datagram: A basic unit of data transmitted over an IP network, containing header information for routing and delivery.
• IP Layer: The network layer in TCP/IP, managing packet routing and addressing using IP addresses.
• IPv4: The fourth version of IP, using 32-bit addresses (e.g., 192.168.1.1.); still widely used, gradually replaced by IPv6.
• IPv6: The sixth version of IP, using 128-bit addresses, providing a larger address space.
