Answer: Memory hierarchy is the hierarchy that is created on the basis of the response time of different memories. The performance obtained by the memory helps in creating a computer storage space in distinguished form. The factors considered for the creating of the hierarchy structure are usually response time, storage capacity, complexity etc.

Usage of different kind of memories take place due to different kind of requirements from the system which cannot be fulfilled using one memory device.The requirement is based on saving time, decreasing complexity , improving performance etc.Example of requirements can be like some functions and files do not require much space , some might require quick accessing,etc.

Thus hierarchy of any particular system is in the form of fast to slow order from registers,cache memory, Random access memory(RAM) and secondary memory.

Answer:

d. The system of water spray pipes did not have sufficient water supply

Explanation:

The Union Carbide India Ltd. was chemical factory situated at Bhopal that produces various pesticides, batteries, plastics, welding equipment, etc. The plant in Bhopal produces pesticides. In the year 1984, on the night of 2nd December, a devastating disaster occurred on the Bhopal plant which killed millions of people due to the leakage of the poisonous, methyl isocyanate. This disaster is known as Bhopal Gas tragedy.

What are availabilities and uses of solar energy/panels? (please explain as much as you can)

mixer [17]

Solar panels can be very useful, an they help reduce the use of other power plants that release pollutants into the air. Solar panels have some cons, as the very good ones that have better cells that can store more energy are more expensive, but it is worth the investment, because a big enough field of panels can power a lot of a things during a power outage.

If anyone else has anything about the availability of solar panels, feel free to add.

Hope this helps :)
