Which of the following statements is/are correct? 1.In June 2016, the LIGO group of scientists announced the detection of a second set of gravitational waves. 2.Gravitational waves were generated due to merger of two black holes at about 1.4 billion light-years distant. 3.Gravitational waves were inserted due to collision of two white dwarf stars at about 1.4 billion light-years distant. Select the correct answer using the code given below.

Correct Answer: 1, 2 and 3

All are correct. Gravitational waves don’t get distorted or altered by interactions with matter as they go through space. gravitational waves have pure information about the objects and events that created them. The Government of India has given approval for the world’s third advanced Laser Interferometer Gravitational Wave Observatory (LIGO-India) to set up in India.

How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
3. You can improve the CSMA/CD network by adding more hubs.
4. After a collision, the station that detected the collision has first priority to resend the lost data.
5. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
