A relational databases typically have two types of fields: a foreign key field in one table, and a primary key field in the other table.
What is database?
Any type of data may be stored, maintained, and accessed using databases. They gather data on individuals, locations, or objects. It is gathered in one location so that it may be seen and examined. You might think of databases as a well-organized collection of data.
In a relational database, two tables that are connected to form a relationship typically have two types of fields: a foreign key field in one table, and a primary key field in the other table.
The foreign key field in one table is used to refer to the primary key field in the other table. For example, consider a database that has two tables: a "customers" table and an "orders" table. The "customers" table might have a primary key field called "customer_id", and the "orders" table might have a foreign key field called "customer_id" that refers to the "customer_id" field in the "customers" table.
The primary key field in a table is used to uniquely identify each record in the table. It is typically a field that contains a unique value for each record, such as a customer's ID number or a product's serial number. The primary key field is often used as the foreign key field in other tables to establish relationships between those tables.

A company has a popular gaming platform running on AWS. The application is sensitive to latency because latency can impact the user experience and introduce unfair advantages to some players. The application is deployed in every AWS Region it runs on Amazon EC2 instances that are part of Auto Scaling groups configured behind Application Load Balancers (ALBs) A solutions architect needs to implement a mechanism to monitor the health of the application and redirect traffic to healthy endpoints.
Which solution meets these requirements?
A . Configure an accelerator in AWS Global Accelerator Add a listener for the port that the application listens on. and attach it to a Regional endpoint in each Region Add the ALB as the endpoint
B . Create an Amazon CloudFront distribution and specify the ALB as the origin server. Configure the cache behavior to use origin cache headers Use AWS Lambda functions to optimize the traffic
C . Create an Amazon CloudFront distribution and specify Amazon S3 as the origin server. Configure the cache behavior to use origin cache headers. Use AWS Lambda functions to optimize the traffic
D . Configure an Amazon DynamoDB database to serve as the data store for the application Create a DynamoDB Accelerator (DAX) cluster to act as the in-memory cache for DynamoDB hosting the application data.
Write a program that accepts an integer value called multiplier as user input. Create an array of integers with ARRAY_SIZE elements. This constant has been declared for you in main, and you should leave it in main. Set each array element to the value i*multiplier, where i is the element's index. Next create two functions, called PrintForward() and PrintBackward(), that each accept two parameters: (a) the array to print, (b) the size of the array. The PrintForward() function should print each integer in the array, beginning with index 0. The PrintBackward() function should print the array in reverse order, beginning with the last element in the array and concluding with the element at index 0. (Hint: for help passing an array as a function parameter, see zybooks section 6.23) As output, print the array once forward and once backward.
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
void PrintForward(int myarray[], int size){
for(int i = 0; i<size;i++){ cout<<myarray[i]<<" "; }
}
void PrintBackward(int myarray[], int size){
for(int i = size-1; i>=0;i--){ cout<<myarray[i]<<" "; }
}
int main(){
const int ARRAY_SIZE = 12;
int multiplier;
cout<<"Multiplier: ";
cin>>multiplier;
int myarray [ARRAY_SIZE];
for(int i = 0; i<ARRAY_SIZE;i++){ myarray[i] = i * multiplier; }
PrintForward(myarray,ARRAY_SIZE);
PrintBackward(myarray,ARRAY_SIZE);
return 0;}
Explanation:
The PrintForward function begins here
void PrintForward(int myarray[], int size){
This iterates through the array in ascending order and print each array element
for(int i = 0; i<size;i++){ cout<<myarray[i]<<" "; }
}
The PrintBackward function begins here
void PrintBackward(int myarray[], int size){
This iterates through the array in descending order and print each array element
for(int i = size-1; i>=0;i--){ cout<<myarray[i]<<" "; }
}
The main begins here
int main(){
This declares and initializes the array size
const int ARRAY_SIZE = 12;
This declares the multiplier as an integer
int multiplier;
This gets input for the multiplier
cout<<"Multiplier: "; cin>>multiplier;
This declares the array
int myarray [ARRAY_SIZE];
This iterates through the array and populate the array by i * multiplier
for(int i = 0; i<ARRAY_SIZE;i++){ myarray[i] = i * multiplier; }
This calls the PrintForward method
PrintForward(myarray,ARRAY_SIZE);
This calls the PrintBackward method
PrintBackward(myarray,ARRAY_SIZE);
return 0;}
Enumerate a couple of reasons why it would be impracticable for the external devices to be connected directly to the processor or the system bus
Answer:
(a) Difference in data transfer rates
(b) Difference in word lengths
(c) Different peripherals with different modes of operation
Explanation:
There are several reasons. Some of them have been listed in the explanation section. A brief explanation is as follows
(a) Difference in data transfer rates
Some peripherals have fast transfer rate while some have slow transfer rates compared to the processor they are being connected to. This difference in the rates implies that a high speed system bus will find it difficult to communicate with a (say) low speed peripheral.
(b) Difference in word lengths
Another consideration is the word lengths. Often times, peripherals and the bus they are being connected with will have a different word lengths.
(c) Different peripherals with different modes of operation
In computer architecture, a processor can not be used to interact with peripheral of different mode of operations. In other word, each peripheral have its own mode and will require different means of connection.

Answer:
systems used by many providers require customers to share bandwidth with neighbors
Explanation:
One of the disadvantages of cable technology is that systems used by many providers require customers to share bandwidth with neighbors. This ultimately causes many problems since cables would need to be extended to reach every single user that will be sharing the bandwidth. This would mean cables all over the place. Also, it is very difficult to limit the bandwidth per person, meaning that if anyone is using up all of the bandwidth through the cable, the rest of the individuals connected would not have the bandwidth that they need or are paying for.

Answer:
I used the names George Clooney and Tim Allen to remember the pairs of nitrogenous bases in DNA.
Explanation:
DNA is composed of nucleotides, however the nucleotides are formed by nitrogenous bases called Adenine, Guanine, Cytosine and Thymine. Each nucleotide has a nitrogenous base, but these bases form pairs, allowing the nucleotides to come together. The pairs are formed solely by Timine and Adenine or Guanine and Cytosine.
As I needed to remember the formation of the pairs to do my biology test, I associated the first letter of each base, with the initials of two famous names.
As Guanina is paired with Cytosine (G-C), I associated this pair with the initial letters of the name George Clooney. As Timina is paired with Adenina (T-A), I associated this pair with the initials of the name Tim Allen.
