1.4. Terminologies and acronyms
This section will define commonly used terms in this manual. These terms are related to
Internetworking, and defined in regards to their use with Pro Series.
 MAC address
On a local area network or other network, the MAC (Media Access Control) address is the computer's
unique hardware number. (On an Ethernet LAN, it is the same as the Ethernet address.)
It is a unique 12-digit hardware number, which is composed of 6-digit OUI (Organization Unique
Identifier) number and 6-digit hardware identifier number. The Pro Series has the following MAC
address template: 00-01-95-xx-xx-xx. The MAC address can be found on the bottom of the original
package.
 Host
A user’s computer connected to the network
Internet protocol specifications define "host" as any computer that has full two-way access to
other computers on the Internet. A host will have a specific "local” or “host number" that, together with
the network number, forms its unique IP address.
 Session
A series of interactions between two communication end points that occur during the span of a single
connection
Typically, one end point requests a connection with another specified end point. If that end point
replies, agreeing to the connection, the end points take turns exchanging commands and data ("talking
to each other"). The session begins when the connection is established at both ends and terminates
when the connection is ended.
 Client/Server
Client/server describes the relationship between two computer programs in which one program, the
client, makes a service request from another program, the server, which fulfills the request.
A server is a computer program that provides services to other computer programs on one or
many computers. The client is the requesting program or user in a client/server relationship. For
example, the user of a Web browser is effectively making client requests for pages from servers all
over the Web. The browser itself is a client in its relationship with the computer that is getting and
returning the requested HTML file. The computer handling the request and sending back the HTML file
is a server.
