Broadcasting and Television Media

VDU stands for Visual Display Unit, which is the technical term for a computer monitor or screen that displays visual output. Options A and D are plausible-sounding but incorrect expansions of the acronym. Option C contains an unrelated word that has nothing to do with display technology.

IPTV stands for Internet Protocol Television, which delivers television content over IP networks instead of traditional terrestrial, satellite, or cable formats. It allows for interactive services and on-demand content delivery.

Under FCC regulations, FM radio stations use 200 kHz channel spacing. With the FM band spanning 88-108 MHz (20 MHz total), approximately 150 stations can theoretically operate in a given area when considering proper geographic separation and adjacent channel protection rules.

Traditional telephone lines (POTS) use a 4 kHz voice-grade channel. The standard range is approximately 300 Hz to 3.4 kHz, requiring about 4 kHz of bandwidth to transmit voice signals with adequate quality.

PCM (Pulse Code Modulation) is the fundamental process of converting analog signals (like voice) into digital format. It samples the analog signal, quantizes the values, and encodes them as binary digits - the core of analog-to-digital conversion.

Television uses an antenna to receive signals, just as a radio uses an aerial (another term for antenna). The relationship is 'device : signal receiving component'.

GSM (Global System for Mobile Communications) is the cellular telephone system widely used in Europe. AMPS and D-AMPS are primarily American systems, while IS-95 is a CDMA-based system.

Transmission media are categorized as guided (like wires and cables) or unguided (like wireless). Guided media have a physical path, while unguided media transmit through air/vacuum.

IRDA (Infrared Data Association) is the organization that sponsors and develops standards for infrared wave communication. EIA and FCC are regulatory bodies, while PUD is not related to infrared.

frequency is inversely proportional to the wavelength

Video cassettes (VHS format) play from only one side, unlike audio cassettes which have two sides. The magnetic tape in a video cassette is arranged as a single continuous loop that plays from beginning to end, and you don't need to flip it over to access more content.

The Sony Bravia V5 series was indeed part of Sony's LCD television lineup, representing one of their contemporary LCD TV models. Option A correctly identifies this as a Sony LCD TV model, though "latest" is time-dependent and this question reflects historical product information.

All of the above are the true statements about transmission in networking.

DTH does away with the need for the local cable operator and puts the broadcaster directly in touch with the consumer. Only cable operators can receive satellite programmes and they then distribute them to individual homes.

Rajdhani Channel is a premium express mail service by India Post for fast delivery of mail between major cities, particularly for business and official correspondence.
