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. 

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

.  

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 

 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 lightweight or time-sensitive purposes. 

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. 

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. 

 
VoIP  

Voice over IP 

VoIP encompasses many protocols. All the protocols do some form of signalling of call 
capabilities and transport of voice data from one point to another. e.g: SIP, H.323, etc.
