I need he answers as soon as possible, PLEASE!

What is metrical task system algorithm?? and can we use that in online shopping project??

jeyben [28]

Answer:

Metrical task system algorithm is the online algorithm that is used for organizing the online problems like k-server issues, paging issues etc.This task system works in the form of metrics to decrease the complete cost experienced due to processing of the operation and analyzing the competition.

It can be used for the online shopping project for the analyzing the comparison between the performance on basis of online and offline trends and then optimization can take place according to the the results.

More registers appear to be a good thing, in terms of reducing the total number of memory accesses a program might require. Give

Answer:

Following is given the answer step by step:

Explanation:

First of all we will write a program using MARIE that will support the statement: Sum = (A + B) - (C + D). All the necessary comments are given in front of each statement:

Load A # variable A will be loaded

Add B # B will be added to A

Store Temp1 # A + B will be stored in Temp1

Load C # C will be loaded in memory

Add D # D will be added to C

Store Temp2 # C + D will ge stored in Temp2

Load Temp1 # Temp1 will be loaded in the memory

Subt Temp2 # Temp2(A + B) get subtracted from Temp1(A - B)

Store Sum # (A + B) - (C + D) will get stored in Sum.

We can see from above program that memory is accessed 9 times. While if C + D get executed first than memory accesses will be reduced to 7.

Above same program could be written using an architecture of 4 registers:

R1
R2
R3
R4

The program is as follows:

Load R1 , A #A will be loaded into R1

Load R2 , B # B will be loaded into R2

Add R1 , R2 # R2 gets added to R1 and the result is stored in R1 (A + B)

Load R3 , C # C loaded into R3

Load R4 , D # D loaded into R4

Add R3 , R4 # Value in R4 gets added into R3 and R3 becomes (C + D)

#no memory accesses required for this operation

Subt R1 , R4 #R4 (C + D) gets subtracted from R1 (A + B)

#no memory accesses required for this operation

Store Sum # The recent value will be stored into Sum

Here memory is accessed 5 times in total.

madam [21]

Answer:

d. It is assumed that the search pool is ordered.

Explanation:

A binary search/logarithimic search/half interval search/binary chop refers to search algorithm in computer science that sorts data in array in key:value arrangements. In order to locate a value in binary search, the key to the value in a sorted array is located. A binary search is characterized by an ascending, descending order arrangement of the array.

Describe the steps involved in data mining or data analytics when viewed as a process of knowledge discovery.

Aleksandr [31]

Answer:

1. Data Cleaning

2. Data Integration

3. Data Selection

4. Data transformation

5. Data Mining

6. Pattern Evaluation

7. Knowledge presentation

Explanation:

The steps involved in data mining or data analytics when viewed as a process of knowledge discovery includes the following:

Step 1. Data cleaning: this involves the elimination of inconsistent data.

Step 2. Data integration: this involves the combination of data from multiple sources.

Step 3. Data selection: this is the step where significant data for task examination are gathered from the database.

Step 4. Data transformation: this the step in which the data are modified for mining by conducting the aggregate operation.

Step 5. Data mining: this step involves the extraction of data patterns through specific techniques.

Step 6. Pattern evaluation: this step involves the identification of patterns that depict knowledge based on measures.

Step 7. Knowledge presentation: this is the step in which visualization and knowledge representation methods are utilized to illustrate mined knowledge to users.
