Answer:

Explanation:

Hadoop clusters can boost the processing speed of many big data analytics jobs, given their ability to break down large computational tasks into smaller tasks that can be run in a parallel, distributed fashion.

Declare a typedef struct named jumper_t that will have four parts: character array name that is 16 in length, double array of tr
Maurinko [17]

Answer:

The typedef struct is as follows:

typedef struct jumper_t {

  char name[16];

  double tries[N_TRIES];

  double best_jump;

  double deviation;

} jumper_t;

The declaration of jlist is:

jumper_t jlist[10];

Explanation:

This defines  the typedef structure

typedef struct jumper_t {

The following declares the variables as stated in the question

<em>   char name[16]; </em>

<em>   double tries[N_TRIES]; </em>

<em>   double best_jump; </em>

<em>   double deviation; </em>

}

This ends the typedef definition

jumper_t;

(b) The declaration of array jlist is:

jumper_t jlist[10];

An access control system that grants users only those rights necessary for them to perform their work is operating on which secu
solmaris [256]

Answer:

B. Least privilege                

Explanation:

  • The principle of least privilege an important principle in computer security.
  • It limits the access rights for users and only grant them with the rights that are sufficient for them to perform their required task.
  • For example a user is granted privilege to execute a file or manipulate data or use only the resources that are required for them to perform a particular task.
  • This principle can be used only to limit and control access rights to system resources and applications.
  • The least privilege is beneficial as it reduces the risk of unauthorized access.
  • For example a user whose task is data entry and has nothing to do with controlling access or granting access rights to users, will only be allowed to enter data to the DB by the principle of least privilege.

For a new version of processor, suppose the capacitive load remains, how much more energy will the processor consume if we incre
erastovalidia [21]

Answer:

The answer is below

Explanation:

The amount of power dissipated by a processor is given by the formula:

P = fCV²

Where f = clock rate, C = capacitance and V = Voltage

For the old version of processor with a clock rate of f, capacitance C and voltage of V, the power dissipated is:

P(old) = fCV²

For the new version of processor with a clock rate of 20% increase = (100% + 20%)f = 1.2f, capacitance is the same = C and voltage of 20% increase = 1.2V, the power dissipated is:

P(new) = 1.2f × C × (1.2V)² = 1.2f × C × 1.44V² =1.728fCV² = 1.728 × Power dissipated by old processor

Hence, the new processor is 1.728 times (72.8% more) the power of the old processor

while investigating the settings on your SOHO router, you find two IP address reported on the devices's routing table, which is
DochEvi [55]

Answer:

From the two IP addresses, 192.168.2.1 can be listed as the default gateway in local network devices.

The reason is that we are allocated with the ranges that are reserved for the local networks by RFC 1918.

These ranges are given as follows:

  • For (10/8 prefix)  

                            10.0.0.0 - 10.255.255.255

  • (172.16/12 prefix)

                            172.16.0.0 - 172.31.255.255

  • (192.168/16 prefix)

                            192.168.0.0 - 192.168.255.255

Moreover the default gateway for a device can also be known by the commands ipconfig or  ipconfig/all on the command prompt.
