One reason for this is: the processing power needed for the centralized model would overload a single computer.

Explanation:

Companies would be engrossed in achieving and examining the datasets because they can supplement significant value to the desicion making method. Such processing may include complicated workloads. Furthermore the difficulty is not simply to save and maintain the massive data, but also to investigate and extract a essential utilities from it.

Processing of Bigdata can consists of various operations depending on usage like culling, classification, indexing, highlighting, searching etc. MapReduce is a programming model used to process large dataset workloads. Hadoop is designed to scale up from single servers to thousands of machines, each offering local computation and storage.

yarga [219]

If the algorithm is changed for the operations at layer k, the services at k1 will change since the services will be operated after the layer. For the services at k-1, they will not be affected since they are prior to the algorithms.

The web development team is having difficulty connecting by ssh to your local web server, and you notice the proper rule is miss

joja [24]

Answer:

Option b (Port 22) seems to the appropriate choice.

Explanation:

Below seem to be some measure you should take to correct this mistake.

Verify whether Droplet's host IP address seems to be right.
Verify existing connection supports communication over all the utilized SSH port. Any access points can be able to block port 22 and sometimes customized SSH. For illustration, you could do this by checking different hosts who used the same port, using only a recognized working SSH connection. These could help you identify unless the current problem is not particular to clients' Droplet.
Authenticate the Droplet configuration settings. Verify that they're not being configured to DROP 's preferred policy, and do not apply the port to require connectivity.

The SSH server also operates on port 22, by default.

Other choices don't apply to the specified scenario. So that the argument presented above will be appropriate.

Explain how abstraction is used in a GPS system

Pavlova-9 [17]

Answer

Abstraction enables GPS system to facilitate the utilization of well defined interfaces while offering room to add additional levels of functionality which are complex to handle.

Explanation

GPS system applies abstraction to be able to arrange level of complexity on which a user will interact with the system. For example, it establishes a link of satellite positioned and timed systems to allow a radio receiver obtain a signal in four dimension after synchronizing the data of latitude, longitude, attitude and time.

Elza [17]

Answer:

Python code is given below with appropriate comments

Explanation:

#Prompt the user to enter the test score and class rank.

testScore = input()

classRank = input()

#Convert test score and class rank to the integer values.

testScore = int(testScore)

classRank = int(classRank)

#If the test score is greater than or equal to 90.

if(testScore >= 90):

#If the class rank is greater than or equal to 25,

#then print accept message.

if(classRank >= 25):

print("Accept")

#Otherwise, display reject message.

else:

print("Reject")

#Otherwise,

else:

#If the test score is greater than or equal to 80.

if(testScore >= 80):

#If class rank is greater than or equal to 50,

#then display accept message.

if(classRank >= 50):

print("Accept")

#Otherwise, display reject message.

else:

print("Reject")

#Otherwise,

else:

#If the test score is greater than or equal to

#70.

if(testScore >= 70):

#If the class rank is greater than or equal

#to 75, then display accept message.

if(classRank >= 75):

print("Accept")

#Otherwise, display reject message.

else:

print("Reject")

#Otherwise, display reject message.

else:

print("Reject")
