Task 1: Write the function of the following video conferencing terms? 
Video conferencing term 
Its function 
cables  
Cables are a beautiful interactive content creation tool. With 
an easy-to-use interface and real-time visuals, it enables 
rapid prototyping and rapid customization. 
control panels 
A control panel is a flat, often vertical, area where control or 
monitoring instruments are displayed or it is an enclosed unit 
that is the part of a system that users can access, such as the 
control panel of a security system 
high-definition monitors  
A high-definition PC monitor delivers a clearer picture than 
possible with low-definition, low-resolution screens. High-
resolution displays generally have a higher density of pixels 
per inch than past standard TV screens. This high pixel 
density makes the image sharper and clearer because the 
human eye can’t make out individual pixels as easily. 
local participants 
A Local Participant (Locals) is a professional derivatives 
trader who trades for his/her own account. In essence, a self-
employed trader. 
microphones 
A microphone, colloquially called a mic or mike, is a 
transducer that converts sound into an electrical signal. 
Microphones are used in many applications such as 
telephones, hearing aids, public address systems for concert 
halls and public events, motion picture production, live and 
recorded audio engineering, sound recording, two-way 
radios, megaphones, and radio and television broadcasting. 
They are also used in computers for recording voice, speech 
recognition, VoIP, and for other purposes such as ultrasonic 
sensors or knock sensors. 
remote participants

that public body, simultaneously with the physical meeting, 
where the member is not physically present at the meeting. 
speakers 
Speaker is an electroacoustic or mechanical device that 
amplifies speech, music and other sounds. The sound 
frequency is converted into sound vibrations using an 

---

electric current or voltage using a mechanical device. There 
are electrodynamic, dynamic, piezoelectric, condenser, 
electromagnetic and pneumatic types of radio speakers. 
Electrodynamic radio speaker (rated power 0.1-100 and 
frequency range 50-12000 gs), sound speakers consisting of 
several diffuser radio speakers in radio broadcasting 
networks (rated power – 100 and higher, frequency range – 
100-800 gs), sound reinforcement systems and other fields), 
electrodynamic and loudspeaker units (rated power 100 and 
above) are widely used. 
video cameras 
A video camera is an optical instrument that captures videos 
(as opposed to a movie camera, which records images on 
film). Video cameras were initially developed for the 
television industry but have since become widely used for a 
variety of other purposes.
