Answer:

Explanation:

Now youwill have to enable boot logging by utilizing the following command:

$ sudo gedit /etc/default/bootlogd

You will then find the following line in the opened text editor.

# Run bootlogd at startup ?

BOOTLOGD_ENABLE=No

Replace No with Yes i.e.

BOOTLOGD_ENABLE=Yes

Now at any time you will boot, bootlog will be created in the /var/log/boot

how to open it? There are two ways, either through login in as root or use the sudo command to open it.

you can also head over to the log directory by making use of the command cd /var/log

and when you’re there you can now use ls command to check if all files present in the log folder

you will find file boot also.

The two screen captures are attached below

What is the effect of block size in cache design?
Sedaia [141]

Answer:

When designing a cache, you have to consider this things:

  • Delay.
  • Miss rate.
  • Area.

If the cache has a bigger block size may have a lower delay, but when miss the miss rate will be costly. If an application has high spatial locality a bigger block size will do well, but programs with poor spatial locality will not because a miss rate will be high and seek time will be expensive.

Given a collection of n nuts and a collection of n bolts, arranged in an increasing order of size, give an O(n) time algorithm t
kari74 [83]

Answer:

See explaination

Explanation:

Keep two iterators, i (for nuts array) and j (for bolts array).

while(i < n and j < n) {

if nuts[i] == bolts[j] {

We have a case where sizes match, output/return

}

else if nuts[i] < bolts[j] {

this means that size of nut is smaller than that of bolt and we should go to the next bigger nut, i.e., i+=1

}

else {

this means that size of bolt is smaller than that of nut and we should go to the next bigger bolt, i.e., j+=1

}

}

Since we go to each index in both the array only once, the algorithm take O(n) time.

Find the double word-length 2's complement representation of each of the following decimal numbers:a. 3874
miss Akunina [59]

Answer:

-3874₁₀ = 1111 1111 1111 1111 1111 1111 1101 1110₂

Explanation:

2's complement is a way for us to represent negative numbers in binary.

To get 2's complement:

1. Invert all the bits

2. Add 1 to the inverted bits

Summary: 2's complement = -N = ~N + 1

1. Inverting the number

3874₁₀ = 1111 0010 0010₂

~3874₁₀ = 0000 1101 1101₂

2. Add 1 to your inverted bits

~3874₁₀ + 1 = 0000 1101 1101₂ + 1

= 0000 1101 1110₂

You can pad the most signigicant bits with 1's if you're planning on using more bits.

so,

12 bits                          16 bits

0000 1101 1110₂  = 1111 0000 1101 1110₂

They asked for double word-length (a fancy term for 32-bits), so pad the left-most side with 1s' until you get a total of 32 bits.

           32 bits

= 1111 1111 1111 1111 1111 1111 1101 1110
