Static IP

An IP address that has been specifically, instead of dynamically (see DHCP), assigned

 

to a device or system in a network configuration. This type of address requires manual

 

configuration of the actual network device or system and can only be changed manually or

 

by enabling DHCP.

Subnet

(See Subnetwork.)

Subnet address

The portion of an IP address that is specifically identified by the subnet mask as the

 

subnetwork.

Subnet mask

A 32-bit address mask used in IP to identify the bits of an IP address that are used for the

 

subnet address. Using a mask, the router does not need to examine all 32 bits, only those

 

selected by the mask.

Subnetwork

A network that is part of a larger IP network and is identified by a subnet address. Networks

 

can be segmented into subnetworks to provide a hierarchical, multilevel routing structure.

T

TCP (Transmission Control Protocol)

A connection-oriented protocol defined at the Transport layer of the OSI reference model. It provides reliable delivery of data.

TCP/IP (Transmission Control Protocol/Internet Protocol)

The communication protocol (language) of the Internet. Computers and devices with direct access to the Internet are provided with a copy of the TCP/IP program to allow them to send and receive information in an understandable form.

Telnet

A standard terminal emulation utility/protocol that allows a computer to communicate with

 

a remote user/client. A user who wishes to access a remote system initiates a Telnet session

 

using the address of the remote client. The user may be prompted to provide a user name

 

and password if the client is set up to require them. Telnet enables users to log in on remote

 

networks and use those resources as if they were locally connected.

Threshold

(See Reference threshold.)

Threshold status

Reported on the IPL T PCS4 System Status screen in the AC Receptacles section. It indicates

 

the current reference threshold (Full, Standby, None, or Not Set) for each PCS4 receptacle.

 

 

U

 

UID (User ID)

An optional user name, for which a field is provided on the Enter Password window that

 

opens if a password has been assigned to the PCS4.

URL (Universal Resource Locator)

The address that lets a resource on the internet be identified, located, and accessed.
