Answer:
A lookaside buffer translation (TLB) is a memory cache that reduces the time it takes to access a user memory place. TLB includes the most lately used page table entries.
TLB is used to overcome the issue of sizes at the time of paging. Page Table Entry (PTE) is used for framing the memory ,but it uses two references one for finding the frame number
and the other for the address specified by frame number.
<u>Formula for finding effective memory access time-</u>
Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)
Given in question,
Hit ratio = 0.90
Memory Access Time = 150ns
TLB access time= 5ns
Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)
=(5+150) * 0.90 + (5+2*150)*(1-0.90)
=155 * 0.90 + (305*0.1)
=139.5 + 30.5
= 170ns
Answer:
Click “between” under the equal menu, and then enter 90 in the first field and 100 in the second field
Explanation:
Since the user wants to highlight fields which contains value which are greater than 90 and less than 100, the operation seems to work well with “between” operator or between function. Since there is a start range and the end range it is better to deal with between function.
The other choices will not work because the greater than or less than operator works only on single value. Only the “between operations” works well on range of values. All the other options are invalid.
Answer
Public cloud
Explanation
A cloud service is any service that is made available to users who are on demand via internet from the cloud computing service providers. These service providers have servers in their company premises where they offer the services from.
A public cloud is a type of computing in which a service provider makes resources available to the public via the internet. The service provider hosts the cloud infrastructure and delivers computing resources over the Internet Resources vary by provider but may include storage capabilities, applications or virtual machines.

The default constraint gives a value to an attribute when a new row is added to a table.
<h3>Is default a kind of constraint?</h3>
This is known to be a type of constraint that often apply a value to a column if an INSERT statement does not really give the value for the column.
Therefore, one can say that the default constraint gives a value to an attribute when a new row is added to a table.
