Answer:
3 bits
Explanation:
Given a 4- way set associative cache that has 64 blocks of 16 words.
Therefore, the number of sets cache has:

Now,
Cache data size is 16kB
The number of cache blocks can be calculated as:

Now,
Total sets = 
Total sets = 
Now,

n = 6
For 15 bit address for the architecture, the bits in tag field is given by:
15 - (6 + 6) = 3 bits
Thus the tag field will have 3 bits
Answer:
c.Update DNS records dynamically for DHCP clients that don't request updates.
Explanation:
A DNS server is a computer server that contains a database of public IP addresses and their associated host names, and in most cases serves to resolve, or translate, those names to IP addresses as requested.

Dynamic DNS is a method of automatically updating a name server in the Domain Name Server, often in real time.
Answer:
latency
Explanation:
We could have latency if we want to record with a computer, and then we try to hear that record with the headphone.
This is an audio card's characteristic, this is a time between the input, in this case, Sarah recording, and the output Sarah's headphone.
The computer needs time to process the signal, and for that there is latency, but this depends on more of the operative system and the CPU in your computer than the audio card.
