10Base2
Coaxial, Thin Ethernet. The 10 indicates a transfer rate of 10 Mbps. Base indicates a baseband
medium and the 2 indicates that the sections must be a maximum of 200 meters.
10BaseT
RJ45, Twisted Pair Ethernet. The 10 indicates a transfer rate of 10 Mbps. Base indicates a
baseband medium and the T indicates twisted pair wiring.
Bit Rate
The raw speed of data over a serial link. Depending on the type of link this may indicate the
theoretical maximum rates e.g. 10BaseT sends packets of data at 10Mbps but due to overheads and
the availability the actual data throughput is significantly less.
For audio data rates the bitrate is the actual amount of data generated per second
Channel
Audio signal that generates a single audio stream. The signal can be either mono or stereo but will
still be treated a single channel. If the Net-Log is formatted to use dual mono then this is considered
as providing 2 channels. If both audio inputs are formatted as dual mono then a total of 4 channels
will be available.
Client
A node on the network that receives services from a server.
Collision (Cl)
This occurs when two different nodes attempt to use the network at the same time.
Cut
A single continuous piece of audio, either stereo or mono, recorded on the hard drive
dB (decibel)
A ratio of two voltages or signal levels, expressed by the equation
dB = 20LOG(V1/V2)
Adding the suffix “u” denotes that the signal is relative to 0.775V RMS
Adding the suffix “v” denotes that the signal is relative to 1V RMS
DHCP
Dynamic Host Configuration Protocol; Hosts are given configuration information across a network,
usually from a server.
DNS
Domain Name System; TCP/IP applications resolve a name into an IP Address
G.729A
High compression record format primarily designed for speech.
Gain
The degree of amplification, or attenuation, applied to a signal.
Gateway
A router that links one network to another.
Gigabyte or GB
1000 million bytes of data storage for a disk drive or 1073 million bytes of data storage for memory
( i.e. 1024 x 1024 x 1024 bytes)
Host ID
The part of the IP Address identifying the node within the network.
Hub
A device used to connect nodes together to form a network.
IP Address
Internet Protocol Address; A 32-bit address used to locate a node on a network.
kbps
Acronym for kilo (thousand) bits per second
LED
Light Emitting Diode.
Link
A connection to a network.
Mbps
Acronym for Mega (million) bits per second
MPEG
Acronym for Motion Picture Experts Group who were responsible for the initial audio compression
specification
NetworkID
The part of the IP Address identifying the address of the local network.
NIC
Network Interface Card; A card placed in a PC or Device used to connect to a network.
Node
A device connected to a network, usually a PC or Printer.
Octet
Eight bits. There are four octets in an IP Address.
Rx
Shorthand for Receiver
Sample Rate
The frequency at which the incoming audio is sampled. The higher the sample rate the higher the
frequency of the audio that will be captured.
Subnet Mask
A mask address to determine the NetworkID and HostID contained in an IP Address.
Switch
An intelligent hub.
TCP/IP
Transmission Control Protocol/Internet Protocol;
THD
The Total Harmonic Distortion is the percentage presence of signals outside the measured frequency
range.
Tx
Shorthand for Transmitter
UTC
Acronym for Universal Time Code which is an internet reference time based on Greenwich Mean
Time
UTP
Acronym for Unshielded Twisted Pair which is the description of the type of cable normally used
networking or phone connections
