Glossary of Terms

Subscriber identity module—circuit stored on a

small card inserted into a mobile phone or

computer, or other mobile device. The SIM

card is used to identify and authenticate the

user.

SLC

Software license code—product registration

code required for using the XProtect Essential

software. If you do not have system

administration responsibilities, you do not have

to deal with SLCs. System administrators use

SLCs when installing and registering the

software.

SMTP

Simple Mail Transfer Protocol—standard for

sending e-mail messages between mail

servers.

Subnet

A part of a network. Dividing a network into

subnets can be advantageous for

management and security reasons, and may in

some cases also help improve performance.

On TCP/IP-based networks, a subnet is

basically a part of a network on which all

devices share the same prefix in their IP

addresses, for example 123.123.123.xxx,

where the first three numbers (123.123.123)

are the shared prefix. Network administrators

use subnet masks to divide networks into

subnets.

T

TCP

Transmission Control Protocol—protocol (or

standard) used for sending data packets

across networks. TCP is often combined with

another protocol, IP (Internet Protocol). The

combination, known as TCP/IP, allows data

packets to be sent back and forth between two

points on a network for longer periods of time,

and is used when connecting computers and

other devices on the internet.

TCP/IP

Transmission Control Protocol/Internet

Protocol—combination of protocols (or

standards) used when connecting computers

and other devices on networks, including the

internet.

Telnet

Terminal emulation program used on TCP/IP

networks. With Telnet, you can connect to a

server from a computer on the network and

execute commands through Telnet as if you

were entering them directly on the server.

Windows includes a client for use with Telnet.

Transact

An add-on to your XProtect VMS system.

XProtect Transact can help you prevent loss

and shrinkage through video evidence

combined with time-linked POS or ATM

transaction data.

U

UDP

User Datagram Protocol—connectionless

protocol for sending data packets across

networks. Primarily used for broadcasting

messages. UDP is a fairly simple protocol, with

less error recovery features than, for example,

the TCP protocol.

UPS

A UPS (Uninterruptible Power Supply) works

as a battery-driven secondary power source,

providing the necessary power for saving open

files and safely powering down your system in

the event of power irregularities. UPSs vary in

sophistication, but many UPSs include

software for automatically saving open files, for

alerting system administrators, etc.

URL

Uniform Resource Locator; an address of a

resource on the World Wide Web. The first

part of a URL specifies which protocol (or data

1 2 ... 174 175 176 177 178 179 180 181 182 183 184 ... 188 189
