TCP Transmission Control Protocol is one of the core protocols of the Internet protocol suite. Using TCP,

applications on networked hosts can create connections to one another, over which they can exchange

data or

packets. The protocol guarantees reliable and in-order delivery of sender to receiver data.

TFTP Trivial File Transfer Protocol, is a very simple

file transfer protocol, with the functionality of a very

basic form of

FTP; It uses UDP (port 69) as its transport protocol.

UDP User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using

UDP, programs on networked computers can send short messages known as

datagrams to one another.

UDP does not provide the reliability and ordering guarantees that

TCP does; datagrams may arrive out of

order or go missing without notice. However, as a result, UDP is faster and more efficient for many light-

weight or time-sensitive purposes.

VAD Voice Activity Detection or Voice Activity Detector is an algorithm used in speech processing

wherein, the presence or absence of human speech is detected from the audio samples.

VLAN A virtual

LAN, known as a VLAN, is a logically-independent network. Several VLANs can co-exist

on a single physical

switch. It is usually refer to the IEEE 802.1Q tagging protocol.
