Term

TCP/IP

 

Definition
Suite of specialized protocols called subprotocols
Term
Routable
Definition
Protocols that can span more than one LAN
Term
TCP
Definition
operates in the Transport layer of the OSI model and provides reliable data delivery services.  Connection Oriented
Term
Source Port
Definition
Indicates the port number at the source node
Term
Port Number
Definition
The address on a host where an application makes itself avialable to incoming our outgoing data
Term
UDP - User Datagram Protocol
Definition
Belongs to transport layer, connectionless transport service, more efficient for carrying message that fit with in one packet Header has four fields
Term
IP
Definition
Belongs to network layer enables TCP/IP to internetwork.  Connectionless protocol
Term
Internetwork
Definition
trasverse more that one LAN segment and more than type of network though a router
Term
ICMP
Definition
Network layer protocol that reports on the sucess or failure of data delivery. 
Term
IGMP
Definition
Operates at Network layer manages mutlicasting
Term
Mutlicasting
Definition
transmission method that allows one one node to send data to a defined groups of nodes
Term
ARP - address resolution protocol
Definition
network layer protocol that obtains the MAC address of a host, or node and then creates a database that maps the MAC address of another node
Term
Dynamic ARP table entries
Definition
are created when a client makes an ARP request that cannot be satisfied by data already in the ARP table
Term
IP
Definition
the core protocol reponsibile for logical adressing
Term
subnet mask
Definition
special 32 bit number that when combined with a device's IP adress informs the rest of the network about the segment or network to which the device is attached
Term
BOOTP
Definition
application protocol uses a central list of IP address and their associated devices
Term
DHCP
Definition
surpassed BOOTP as the most sphisticated IP addressing utility
Term
unicast address
Definition
IPv6 address that represents a signle interface on a device
Term
multicast address
Definition
represents mulitple interfaces
Term
anycast address
Definition
represent any one interface from a group of interfaces ay of which can accept a transmission
Term
Format prefix
Definition
IPv6  variable length field at the begininng of the address that indicates what type of address it is
Term
socket
Definition
a process's port number plus its host machine's IP address
