Computers and Technology

vodomira [7]3 years ago

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

In one to three sentences describe one reason you would import data into a datebase
Bond [772]

The primary reason that you would import data into a database is because the data already exists somewhere else.

As an example, you may have a spreadsheet that contains names and telephone numbers of a group of people. It is much faster to import this data into a database instead of manually entering the information.

Which phrase describes this image most precisely?
KIM [24]

The correct answer is D. A nice bunch of colorful flowers in a transparent water jug with a handle.

Explanation:

Describing an image precisely requires using specific details that allow others to understand or imagine the image even without seeing it. Due to this, to describe this image precisely it is a good idea to include as many accurate details as possible, which includes words such as "colorful", "flowers", "transparent", etc. In this context, the best option is D because this offers more details than other options and all of these details are accurate and specific.
