C Correct answer
Explanation

DTH stands for Direct-to-home television. It is defined as the reception of satellite programmes with a personal dish in an individual home. Only cable operators can receive the satellite programmes which are transferred by them to individual homes. Hence, DTH services are provided by cellular companies.

Analog signals can be ___________ by combining them with a carrier frequency. 

  1. Carried

  2. Transported

  3. Multiplexed

  4. Mixed
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Analog signals can be Carried by combining them with a carrier frequency.

Frequency Division Multiplexing (FDM) is a networking technique in which multiple data signals are combined for simultaneous transmission via a shared communication medium. FDM uses a carrier signal at a discrete frequency for each data stream and then combines many modulated signals.

This set of Computer Networks Multiple Choice Questions & Answers (MCQs) focuses on “Multiplexing”. Explanation: FDM and WDM are used in analog signals. Explanation: Each slot is dedicated to one of the source. Explanation: Transmission rate= frame rate * number os bits in a slot.

An analog signal is a continuous signal that contains time-varying quantities. Unlike a digital signal, which has a discrete value at each sampling point, an analog signal has constant fluctuations.

C Correct answer
Explanation

Intel has disclosed its silicon technology for high definition, large screen TVs. The new technology, code named cayley is based on liquid crystal on silicon (LCOS).

Liquid crystal on silicon is a micro display technology in which liquid crystals are fabricated on a silicon device that contains control electronics. These devices compete with digital light processing (DLP) technology in the projector and pico projector markets. Viewfinders in camera products are another key application area.

An example of digital rather than Analog Communication is _____________.

  1. DDD

  2. DDS

  3. WATS

  4. DDT
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An example of digital rather than analog communication is DDS.

DDS:-

Direct digital synthesis (DDS) is a powerful technique used in the generation of radio frequency signals for use in a variety of applications from radio receivers to signals generators and many more. The technique has become far more widespread in recent years with the advances being made in integrated circuit technology that allow much faster speeds to be handled which in turn enable higher frequency DDS chips to be made.

Digital communication:-

Digital communication is a mode of communication. It occurs when the information or the thought is encoded digitally as discreet signals and then is electronically transferred to the recipients. Digital means of communication like messaging apps are surging in popularity all over the world.

Analog communication:-

Analog communication is a data transmitting technique in a format that utilizes continuous signals to transmit data including voice, image, video, electrons etc. An analog signal is a variable signal continuous in both time and amplitude which is generally carried by use of modulation.

Government has divided the carrier frequency range from 30 Mhz to 60 Mhz between 20 stations which are independently beaming their signals. Which of the signals can be beamed by each of the stations :-

  1. Voice signals only

  2. Music signals and voice signals only

  3. TV Signals, Music Signals as well as voice signals

  4. Music signals only
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The frequency range provided is typically allocated for narrow-band communication, which is sufficient for voice signals but lacks the bandwidth required for high-fidelity music or video (TV) signals.

The working of mobile is similar to the working of which of the following devices?

  1. T.V

  2. Radio

  3. FAX

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cellphone and radio works the same way. Cellphone can be said as a two way radio as both the sender and receiver can send audio signals simultaneously while in radio only audio signals are sent one way from sender to receiver .

The way mobile works is same as radio .The audio waves goes to the mic where they are converted to electric signals,then they are carried to receiver's device by modulation and then again the receiver's  device converts the electric signals to the audio output.

Two-way radio device is called ________ .

  1. FAX machine

  2. Radio

  3. Mobile phones

  4. Microwave
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mobile phones are called two way radio devices as the communication is done the same way as Radio , but here both the sender and receiver can send information at the same time simultaneously . Unlike the radio;s where only sender can send the information and receiver will receive it at a moment of time
