IS3120 CHAPTER 5 Flashcards
The process of finding an IP address for a host name
Address resolution
Sending a packet to a complete range of IP addresses
Broadcasting
The original addressing architecture used for the Internet
Classful network
A strategy that allows IANA to segment any IPv4 address space to define larger or smaller networks as needed.
Classless Inter-Domain Routing (CIDR)
A communication protocol that sets up a connection with the remote node before exchanging messages with it. Both participants in the conversation use the same connection for the duration of the conversation.
Connection-oriented protocol
A communication protocol that does not require a redefined connection and treats each packet as a separate entity.
Connectionless protocol
Layer 3 protocol units of data sent to a destination node, also called network packets.
Datagrams
A hierarchical naming system that allows organizations to associate host names with IP address name spaces.
Domain Name System (DNS)
Standard notation for IPv4 addresses.
Dot notation
A network software implementation in which the operating system supports both IPv4 and IPv6 using two separate network stacks for the Internet Protocol
Dual IP stack
The process of adding the IP header data to a network packet.
Encapsulation
Process in which IP software chops packets into smaller packets, allowing computers to send large packets acres a network that can only handle smaller packets.
Fragmentation
A mode of operation in which both ends of a connection between computers can communicate simultaneously
Full duplex
A mode of operation in which both ends of a connection between computers can communicate, but only one at a time.
Half duplex
A collection of standards that define the Data Link Layer protocol for accessing wired Ethernet
IEEE 802.3
The organization responsible for coordinating IP addresses and resources around the world.
Internet Assigned Numbers Authority (IANI)
A global volunteer organization that develops and promotes Internet standards
Internet Engineering Task Force (IETF)
Protocol used by IPv6 networks to provide a similar service as ARP
Neighbor Discovery Protocol (NDP)
.The process of replacing a private IP address with a public IP address, or vice versa
Network Address Translation (NAT)
A set of rules that define a particular aspect of communication.
Protocol
A mode operation for communication between computers in which only the source can send data to the destination, and the destination cannot respond.
Simplex
A binary number that contains all 1’s in the leftmost prefix length positions, and all other bits are 0’s
Subnet mask
A descriptive framework for computer network protocols, ceased by the US department of Defense in the 1970’s.
Transmission Control Protocol/Internet Protocol (TCP/IP) Reference model
IPv6 addresses that specify a unique device
Unicast addresses
A strategy to allow IPv4 networks to be fragmented into any size subnetwork.
Variable Length Subnet Masking (VLSM)
