With reference to Visible Light Communication (VLC) technology, which of the following statements are correct? (1) VLC uses electromagnetic spectrum wavelengths 375 to 780 nm. (2) VLC is known as long-range optical wireless communication. (3) VLC can transmit large amounts of data faster than Bluetooth, (4) VLC has no electromagnetic interference. Select the correct using the code given below: (a) 1, 2 and 3 only (b) 1, 2 and 4 only (c) 1, 3 and 4 only (d) 2, 3 and 4 only   ANSWERS 1. (a) The land measures used in eastern India included the adhavapa (3/8–1/2 acre), dronavapa (1½–2 acres), and kulyavapa (12–16 acres). These were the areas required to sow one adhaka, drona, and kulya of grain respectively. Pataka was another land measure, and seems to have been equivalent to 60–80 acres. Other terms included pravartavapa (this was much smaller than a kulyavapa), padavarta (over 1 ft), and bhumi. The large number of land measure terms indicate that there was no single standard set of measurement and that different measures were current in different regions. 2. (d) 3. (d) Munda Rebellion is one of the prominent 19th century tribal rebellions in the subcontinent. Birsa Munda led this movement in the region south of Ranchi in 1899-1900.The ulgulan, meaning 'Great Tumult', sought to establish Munda Raj and independence. 4. (d) 5. (c) Visible Light Communication (VLC) systems employ visible light for communication that occupy the spectrum from 380 nm to 750 nm. The technology uses fluorescent lamps (ordinary lamps, not special communications devices) to transmit signals at 10 kbit/s, or LEDs for up to 500 Mbit/s over short distances. The Visible Light Communication (VLC) is an emerging technology, which provides distinct facilities such as fast data communication, secure data communication, high data rate wireless communication, .Instead of radio frequency, VLC uses light, to transfer data. The visible light spectrum is unlicensed and 10,000 times larger than the range of radio frequencies. It can be used as an alternate to the existing radio based wireless communication technologies or in hybrid. Moreover, Integrated VLC resolves issue of load balancing in existing wireless networks. Light Fidelity is a recent technology under VLC, which can be used for wireless communication as it has many advantages such as no electromagnetic interference, low cost and high data rate, much higher than traditional bluetooth.
