Answer:

The Central Processing Unit

Explanation:

The Central Processing Unit is the brains of the computer where most calculations take place. A central processing unit (CPU), also called a central processor or main processor is the electronic circuitry within a computer that executes instructions that make up a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions.

Answer:

Unit Control (UC)

Explanation:

In the Central Processing Unit (CPU) are:

• <em>Control Unit (CU) </em>

• The logical arithmetic unit (ALU)

• Local memory

Control Unit (CU), information flow:

1. Fetch Instruction the memory

2. Decode instruction into command

3. Execute Command

4. Store Instruction in memory

The control unit acts by admitting the input data, which it transforms into control signals and which are subsequently transmitted to the central processor.

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

Given sphereRadius and piVal, compute the volume of a sphere and assign to sphereVolume. Look up the equation online (e.g., http

fenix001 [56]

Answer:

#include <stdio.h>
int main()
{
const double piVal = 3.14159;
double sphereVolume = 0.0;
double sphereRadius = 0.0;
sphereRadius = 1.0;
sphereVolume = 4.0/ 3.0 * piVal * sphereRadius * sphereRadius * sphereRadius;
printf("Sphere volume: %lf\n", sphereVolume);
return 0;
}

Explanation:

Firstly we can identify the formula to calculate volume of sphere which is

Volume = 4/3 $\pi r^{3}$

With this formula in mind, we can apply this formula to calculate the volume of sphere in Line 10. This is important to perform floating-point division 4.0/3.0 to ensure the resulting value is a floating value as well. Since we have been given piVal and sphereRadius, we can just multiply the result of floating-point division with piVal and sphereRadius and get the sphereVolume value.

At last, display the sphere volume using printf method (Line 13).

Answer:

Hardware.

Explanation:

All electronics devices like computer servers, DVDs, smartphones and cell phones, wrist watches etc, comes with two main components, they are hardware and software.

The hardware components are the physical part of the device, while the software component is the written instructions configured to the hardware for executing tasks.

Cleaning the motherboard in a computer system, fixing a DVD, servicing other internal components of devices are all hardware maintenance and repair services.

A blood bank maintains two tables - DONOR, with information about people who are willing to donate blood and ACCEPTOR, with info

Kipish [7]

Answer:

The sql query is given below.

Since we need to count of males and females for a particular blood group, we put xxx for the blood group.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%") as Male_Donors,

COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%") as Female_Donors

FROM DONOR

WHERE BG = xxx;

Explanation:

The clauses in the query are as follows.

1. SELECT: all the columns required in the output are put in this clause.

2. FROM JOIN ON: the table(s) from which the above columns are taken are put in this clause.

3. WHERE: any condition required to filter the output is put in this clause.

The query is explained below.

1. Find the number of male donors. Number of anything can be found using COUNT() function. A query is required since gender is included in deciding the type of donor.

2. The query is defined to find number of male donors as follows.

COUNT( SELECT DID FROM DONOR WHERE GENDER LIKE "M%"; )

3. In the previous query, LIKE operator is used since it is not defined what value is stored for male donors.

4. Similarly, the query to find the number of female donors is formed.

COUNT( SELECT DID FROM DONOR WHERE GENDER LIKE "F%"; )

5. Next, the final query is formed as follows.

SELECT: both COUNT() functions will come here.

FROM: table name

WHERE: specific blood group will be put here

GROUP BY: this clause is optional and is not used in this query.

HAVING: this clause is optional and is not used in this query.

6. The query after putting all clauses is shown below.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%"),

COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%")

FROM DONOR

WHERE BG = xxx;

7. Alias is used in the above query for each column to get the final query.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%") as Male_Donors, COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%") as Female_Donors

FROM DONOR

WHERE BG = xxx;
