Answer:
The power function can be written as a recursive function (using Java) as follows:
- static int power(int x, int n)
- {
- if(n == 0){
- return 1;
- }
- else {
- return power(x, n-1 ) * x;
- }
- }
Explanation:
A recursive function is a function that call itself during run time.
Based on the question, we know x to the 0th power is 1. Hence, we can just create a condition if n = 0, return 1 (Line 3 - 5).
Next, we implement the logic "x to the nth power can be obtained by multiplying x to the n-1'th power with x " from the question with the code: return power(x, n-1 ) * x in the else block. (Line 6 -8)
In Line 7, power() function will call itself recursively by passing x and n-1 as arguments. Please note the value of n will be reduced by one for every round of recursive call. This recursive call will stop when n = 0.
Just imagine if we call the function as follows:
int result = power(2, 3);
What happen will be as follows:
- run Line 7 -> return power(2, 2) * 2
- run Line 7 -> return power(2, 1) * 2
- run Line 7 -> return power(1, 0) * 2
- run Line 4 -> return 1 (Recursive call stop here)
Next, the return value from the inner most recursive call will be return to the previous call stack:
- power(1, 0) * 2 -> 1 * 2
- power(2, 1) * 2 -> 1 * 2 * 2
- power(2, 2) * 2 -> 1 * 2 * 2 * 2 - > 8 (final output)

Un sistema operativo es el software más importante de tu computador, ya que se encarga de gestionar el hardware, el acceso a la memoria, acceso a la CPU y controlar gran parte de las tareas que lleva a cabo tu computador.
The protocol that should be used to establish a secure network connection for backups is SSH.
<h3>Secure Shell</h3>
SSH stands for <u>Secure Shell</u>. SSH is a <u>protocol that allows users to remotely control and modify servers</u>. SSH is commonly used by administrators to manage certain systems or applications remotely. So the admin can enter the computer via the network, then run various commands to modify or manage files from one computer to another.
SSH has several crucial functions for managing data transfer traffic. Specifically, the following are the functions and benefits of SSH:
- Securing remote access to SSH-enabled systems or network devices for the user and processing them automatically.
- SSH will automatically terminate the connection if there is suspicious activity on the connection used. So you can avoid various cyber threats such as IP and DNS spoofing, data manipulation, illegal tracking, and others.
- Perform automatic and secure file transfers.
- Launch commands securely on remote devices or systems.
- Perform secure component management of network infrastructure.

Answer:
The correct answer to the following question will be "JAWS".
Explanation:
- JAWS is a strong accessibility tool, which uses synthesized speech to look for information on your monitor and provides several helpful commands to make it much easier using applications, edit documentation and read pages of the web.
- It's a Microsoft Windows screen reader tool that helps visually and blind impaired people to decode the screen either via a message-to-speech interpretation or with a castable sign language display.
- JAWS is manufactured by Freedom Scientific Blind and Group of Low Vision.
Therefore, JAWS is the right answer.
Each individual data items of record is called field (letter A).
The client may communicate with Proxy server to use a protocol to proxy the communication between the client and the DBMS. Proxy servers lets you hide your real Ip address and replaces it with a new IP obtained from proxy server sites.
