1.4. Terminologies and acronyms
This section will define commonly used terms in this manual. These terms are related to networking,
and defined in regards to their use with UPSLink.
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 UPSLink 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.
