You use lpstat and determine that a user named User1 has placed two large print jobs in the queue for Printer1 that have yet to

start printing. They have print job IDs of Printer1-17 and Printer1-21, respectively. Which command would you use to remove these two jobs from the print queue

A command that should be used to remove these two print jobs from the print queue is cancel Printer1-17 Printer1-21.

<h3>What is printing?</h3>

Printing can be defined as a process that typically involves sending print jobs from a computer system to a printer, especially through the print queue.

In Computer technology, "cancel Printer1-17 Printer1-21" is a command that should be used to remove the two (2) print jobs from the print queue of Printer1 which is yet to start printing.

Show the array that results from the following sequence of key insertions using a hashing system under the given conditions: 5,
sergejj [24]

Answer:

a) Linear probing is one of the hashing technique in which we insert values into the hash table indexes based on hash value.

Hash value of key can be calculated as :

H(key) = key % size ;

Here H(key) is the index where the value of key is stored in hash table.

----------

Given,

Keys to be inserted are : 5 , 205, 406,5205, 8205 ,307

and size of the array : 100.

First key to be inserted is : 5

So, H(5) = 5%100 = 5,

So, key 5 is inserted at 5th index of hash table.

-----

Next key to inserted is : 205

So, H(205) = 205%100 = 5 (here collision happens)

Recompute hash value as follows:

H(key) =(key+i) % size here i= 1,2,3...

So, H(205) =( 205+1)%100 = 206%100 = 6

So, key 205 is inserted in the 6th index of the hash table.

----------

Next Key to be inserted : 406

H(406) = 406%100 = 6(collision occurs)

H(406) =(406+1) %100 = 407%100 = 7

So, the value 406 is inserted in 7the index of the hash table.

-----------------

Next key : 5205

H(5205) = 5205%100 = 5(collision)

So, H(5205) = (5205+1)%100 = 6( again collision)

So, H(5205) = 5205+2)%100 = 7(again collision)

So, H(5205) = (5205+3)%100 = 8 ( no collision)

So, value 5205 is inserted at 8th index of the hash table.

-------------

Similarly 8205 is inserted at 9th index of the hash table because , we have collisions from 5th to 8th indexes.

-------------

Next key value is : 307

H(307) = 307%100 = 7(collision)

So, (307+3)%100 = 310%100 = 10(no collision)  

So, 307 is inserted at 10th index of the hash table.

So, hash table will look like this:

Key       index

5         5

205         6

406         7

5205 8

8205 9

307         10

b) Quadratic probing:

Quadratic probing is also similar to linear probing but the difference is in collision resolution. In linear probing in case of collision we use : H(key) = (key+i)%size but here we use H(key) =( key+i^2)%size.

Applying Quadratic probing on above keys:.

First key to be inserted : 5.

5 will go to index 5 of the hash table.

-------

Next key = 205 .

H(205) = 205%100 = 5(collision)

So. H(key)= (205+1^2)%100 = 6(no collision)

So, 205 is inserted into 6th index of the hash table.

--------

Next key to be inserted 406:

So, 406 %100 = 6 (collision)

(406+1^2)%100 = 7(no collision)

So, 406 is moved to 7th index of the hash table.

----------

Next key is : 5205

So, 5205%100 = 5 (collision)

So, (5205+1^2)%100 = 6 ( again collision)

So, (5205+2^2)%100 = 9 ( no collision)

So, 5205 inserted into 9th index of hash table.

-----------

Next key is 8205:

Here collision happens at 5the , 6the , 9th indexes,

So H(8205) = (8205+4^2)%100 = 8221%100 = 21

So, value 8205 is inserted in 21st index of hash table.

--------

Next value is 307.

Here there is collision at 7the index.

So, H(307) = (307+1^2)%100 = 308%100= 8.

So, 307 is inserted at 8the index of the hash table.

Key           Index

5                  5

205                  6

406                  7

5205                9

8205               21

307                   8

Which of the following are actions a programmer could take when debugging a segment of code that would most likely lead to findi
Verizon [17]

Answer:

Option B and C are the correct answer for the above question

Explanation:

The above question asked about the work of the programmer to catch an error of the program--

  • Then the option B states that the programmer needs to prints the value of the various program variable on every line of the program which is the correct solution because it is used to find the error easily. It defines the value of every variable in every place of the program and the programmer caught the error statement in the program if anywhere the variable gets the false value.
  • The C option states to help from a friend, it is also a good solution because the friend can easily be caught the error of the program by seeing every line of code.
  • But the other option is not correct because the option A states that the change the name of the variable which is not a result of anything.
  • And the option D states that the code will be retyped again which is also not justify anything.

inn [45]

Answer:

Reseat the new stick of RAM

Explanation:

Joe needs to reseat the new stick of the RAM. For that, he should gently release the clips which hold RAM in the correct posture, and one on each side. Joe is required to do this for each of the available memory modules. And then he will have the cautiously replace all the memory modules( 2 in number) through to DIMM slots which are on the motherboard. Make sure that you have noted down the locations of each notches on the RAM as well as the DIMM slots.
