List the final state of the cache, with each valid entry represented as a record of < index, tag, data >.

1 answer:

8 0

There is not enough information to give correct answer. Anyway, I guess, I've seen this question before and I know the answer. I wrote it in binary. So if your task's details look like this: tag bits 31-10 2; index bits 9-4; offset bits 3:0; your answer is:

<000000, 0001, mem[1024]>
<000001, 0011, mem[3088]>
<001011, 0000, mem[176]>
<001000, 0010, mem[2176]>
<001110, 0000, mem[224]>
<001010, 0000, mem[160]>

Moore’s law refers to?

puteri [66]

Answer:

Moore’s law states that processor speeds, or overall processing power for computers will double every two years.

Explanation:

Moore’s law is more than an observation than a law which was originated in 1970. The observation is about the number of transistors that is present in any system or an integrated system that will be doubled every couple of years.
The real-world application of Moore's law can be seen during computing your business taxes, piloting a spaceship, or changing the television station, etc.

The area of a square is stored in a double variable named area. Write an expression whose value is length of the diagonal of the

melisa1 [442]

Answer:

sqrt(area)

Explanation:

Here sqrt is a short form of square root.
area is a variable name having he area of square.
When the function is called, it will give the square root of the value stored in variable area.

As we have to find the length of the diagonal, we must knew that as all sides of the square are same in length so are the diagonals. This means that each of the four sides of the square and it diagonals are equal in length.

So a square has: length=breadth=diagonal

As Area= length*breadth

√area = length (as length = diagonal length)

So √area = diagonal length

You are implementing a RAID storage system and have found a system with eight 100 GB drives. How much storage space will you hav

asambeis [7]

Answer:

The space available will vary between 800 GB (100%) and 400 GB (50%) of the total disks, depending on the RAID level.

The OS will handle the RAID as a single disk.

Explanation:

Each RAID level implements parity and redundancy in a different way, so the amount of disks used for this extra information will reduce the space available for actual storage.

Usual RAID levels are:

RAID 0: does not implement any redundancy or parity, so you will have available 100% of the total storage: 8 x 100 GB = 800 GB

RAID 1: Duplicates all the information in one disk to a second disk. Space is reduced in half: 400 GB

RAID 5: Uses the equivalent of 1 disk of parity data distributed evenly on each disk, meaning the space available is $\frac{n-1}{n}$ of the total disks: $\frac{7}{8}$ of 800 GB = 700 GB

Writting and reading the information on a RAID storage is handled by a raid controller, either implemented in hardware or software. The OS will "see" a single disk and will read or write information as usual.

During which part of an examination are various body parts and organs touched and felt?

scoray [572]

The correct answer is B. Palpation

Explanation:

In a medical exam or similar, the palpation involves touching different parts of the body to feel the organs and structures in this. This process is essential in diagnosis because palpation can reveal inflammation, pain in certain areas, or abnormalities. Additionally, palpation requires a broad knowledge of anatomy that allows health professionals to understand the structures of the body when they touch these and how to determine abnormalities. Thus, the part of an examination in which body parts are touched and felt is palpation.

hammer [34]

It is both true that Technician A says that the excessive length of a heater hose is intended to protect the heater core from undue stress. Technician B says that excessive wear adds to the length of a heater hose, and a replacement heater hose should be roughly three to four inches shorter than its predecessor. So the asnwer is letter B.
