Indexing. The purpose of storing an index is to optimize speed and performance in finding relevant documents for a search query. Without an index, the search engine would scan every document in the corpus, which would require considerable time and computing power.

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

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0,
TEA [102]

Answer:

ranforce = randi([0, 12]);

if (ranforce == 0)

     disp('There is no wind')

else  if(ranforce>0 && ranforce <7)

     disp('There is a breeze')

else  if(ranforce>6 && ranforce <10)

     disp('This is a gale')

else  if(ranforce>9 && ranforce <12)

     disp('It is a storm')

else  if(ranforce==12)

     disp('Hello, Hurricane!')

end

Explanation:

<em>Replace all switch case statements with if and else if statements.</em>

<em>An instance is:</em>

<em>case {7,8,9}</em>

<em>is replaced with</em>

<em>else  if(ranforce>9 && ranforce <12)</em>

<em>All other disp statements remain unchanged</em>

How are 8-position, 8-contact (8P8C) modular connectors pinned to unshielded twisted-pair (UTP) cable, which is used for connect
AleksandrR [38]

An unshielded cable are twisted pair is used to connect modem in telecommunication industry to connect computer through telephone cable, Ethernet cables it is called as UTP cables.

<u>Explanation:</u>

These UTP cables are twisted cables where conducted are used in form of single circuit.

These types of UTP cables used to connect modem to establish connection to other networks for internet or connecting to other side computer or desktop or laptops.

UTP cables uses  rj-45 or rj-11  or rs232 or rs 499. Normally rs-45 with cat 5e cable is used to connect LAN. Rj-11 is used to connect to modem for dial purpose.

If we use ip networks RJ-45 will do both.
