The JMS API defines a common set of interfaces for creating applications
for reliable asynchronous communication among components in a
distributed computing environment, so that the applications are portable
across different enterprise systems.
Java Virtual Machine
A software technology developed by Sun Microsystems. Software that is
developed using Java can be executed on any processor that is equipped with
a JVM.
Layer 1
The physical layer of the OSI model that includes the required network
hardware and physical cabling for the transmission of raw bits and the
acknowledgement of requests from the data link layer.
Layer 2
The data link or MAC layer of the OSI model that includes the physical
address of a client or server station for inspection by a bridge or switch.
Layer 3
The network layer of the OSI model. It contains the logical address of a
client or server station that is inspected by a router that forwards the address
through the network. L3 contains a type field for traffic prioritization and
forwarding based on the message type as well as on the network destination.
