disk storage.
Decoder - ANSTakes the encoded signal and converts it back to the original signal, or into a
new video or audio format.
Encoder - ANSTakes info from one video or audio format and converts it to another.
Wireless Local Area Network (WLAN) - ANSConnects wireless devices to each other using high
frequency radio signals to communicate data. AKA wi-fi.
Wide Area Network (WAN) - ANSConnects networks that are located in different geographical

more securely. Also allow employees to be at home or travel and access their company's
network remotely.
Virtual Local Area Network (VLAN) - ANSVirtual, logical connection of multiple devices from
different LANs into one network. For example, you can group multiple devices together in a this
network to reduce traffic across the larger network.
Broadcast Domain - ANSA collection of devices that receive broadcast traffic from each other.
Audio Video Local Network - ANSDedicated network specifically for providing secure control of
local AV devices without outside interference or intrusion. Similar to a VLAN since it creates a
separate broadcast domain for the AV devices. Allow the AV system to run even if it's been

Destination - ANSPackets are labeled with a ________ address.... for transmitting across the
network.
sequence - ANSPackets are labeled with a...... __________ number for transmitting across the
network.
Devices - ANSDuring transmission, the data packets travel through various ___________ to
reach their destination.
Reassembled - ANSThe original data is ____________ in the correct order, based on the
sequence number contained within the message packet.
Internet Protocol - ANSThe set of rules that define how computers and devices communicate
over a network
IPv4 - ANSThe most common type of IP. Used by Extron.
Transmission Control Protocol (TCP) - ANSdefines the amount of traffic over the network and is
responsible for actual delivery of the data.
Connection-oriented protcol - ANSonce a connection is established, packets can be sent in two
directions. TCP is considered this.
TCP/IP - ANSTCP and IP working together to control network data transmission.
User Datagram Protocol (UDP) - ANSAn alternative communications protocol. Primarily used for
establishing low latency and loss tolerating connections between applications on the Internet.
Does not have error-checking like TCP, so packets can be lost.
Static IP - ANSaddresses are manually configured and cannot change.
