Answer:

secondary.

Explanation:

In primary soruces we found the sources that were the closest to the events, primary sources would be diary entries or journalistic articles about Abraham Lincoln, since he is not studying that, he is reading from a encyclopedia that has already summarized and interpreted those documents his sources is a secondary source, because secondary sources take the primary sources and study them or summariz them.

Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600 MHz. Computer B has a CPI of 2.5 and can be run at a
kirill115 [55]

Answer:

Check the explanation

Explanation:

CPI means Clock cycle per Instruction

given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M

Execution time is given by following Formula.

Execution Time(CPU time) = CPI*Instruction Count * clock time = \frac{CPI*Instruction Count}{ClockRate}

a)

for system A CPU time is 1.3 * 100, 000 600 106

= 216.67 micro sec.

b)

for system B CPU time is =\frac{2.5*100,000}{750*10^6}

= 333.33 micro sec

c) Since the system B is slower than system A, So the system A executes the given program in less time

Hence take CPU execution time of system B as CPU time of System A.

therefore

216.67 micro = =\frac{2.5*Instruction}{750*10^6}

Instructions = 216.67*750/2.5

= 65001

hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A

The Knowledge Consistency Checker (KCC) ensures the maximum number of hops between any two domain controllers does not exceed wh
Katarina [22]

Answer:

Three (3)

Explanation:

Explanation of the three basic terms here - Knowledge consistency checker, hops and domain controller - will give a clearer answer and explanation to the question as follows;

<em>Domain controller</em> : is a server controller that gives access or controls to users on computer networks by first responding to their authentication requests and verifying those users. In other words, a domain controller is a network security manager.

<em>Hop</em> : A hop is simply the passage of data packets from one network to another. As  a packet moves from its source to destination, it moves from router to router. The number of such routers that the packet passes through is called a hop.

<em>The Knowledge Consistency Checker (KCC)</em> :  It is the job of the KCC to ensure that these domain controllers participate in the replication promptly and orderly. Replication means copying data from one location to another (within a network or among networks). The KCC ensures that the maximum number of hops permitted is does not exceed 3. i.e no domain controller is more than 3 hops from any other domain controller within a network.

Note: Replication is of two types - intrasite (among all domain controllers within a site) and intersite (among all domain controllers in different sites), and the KCC can manage both type of replication. Also, by default, at every 15 minutes interval, a domain controller generates a replication topology (a logical map that dictates the domain controllers that will replicate with each other).

<em>Hope this helps!</em>
