Answer:
Hard drive
Explanation:
The hard drive is where the operating system, programs and data reside on (unless the data is saved and backed up elsewhere). An older hard drive that uses platters for reading and writing data to it will be slower than a later model solid state device. Newer hard drives have very fast access speeds compared to older units.
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.
Soon after the gas pipe exploded, the fire brigade started spraying water into the air to 
the cloud of the gases in the air but there was not sufficient amount of water in the water sprays and so it was not effective.
Thus the correct answer is option (d).
Answer:
NAT
Proxy
IPv6
Explanation:
Network Address Translation (NAT) allows a local area network (LAN) to connect to the internet using only one external IP address. The LAN addresses (typically 192.168.x.x) can be used over and over again.
A proxy is a computer that makes requests to the internet on behalf of the computers on a LAN. It is a more restricted flavour compared to the NAT, but the effect is the same.
IPv6 is a new addressing scheme that will use a 48 bits address space rather than a 32 bits address space of IPv6, and that would provide plenty of addresses.
