Which of the following is true? a. Pseudocode is used to describe an algorithm. b. Pseudocode is not an actual computer programm

Answer:

The code is implemented in Java

1. public class Main {
2.    public static void main(String[] args) {
3.        int count = 0;
4.        Scanner stream = new Scanner(System.in);
5.        System.out.print("Enter a number between 10 and 100: ");
6.        int num = stream.nextInt();
8.        while(num > 0){
9.            if(count % 10!= 0){
10.                System.out.printf("%3d", num);
11.            }else{
12.                System.out.println();
13.                System.out.printf("%3d", num);
14.            }
15.            count++;
16.            num--;
17.        }
18.    }
19. }

Explanation:

To start, initiate a counter named count and set it to zero (Line 3).

Then, instantiate a Scanner object, requesting the user to enter a number from 10 to 100 (Line 4-6).

Implement a while loop that continues as long as the countdown number remains above zero (Line 8). Then, introduce an if statement to determine if the counter is a multiple of 10. If it is not, display the current num; if it is, start a new line before displaying the current num (Line 9 -14).

After each iteration, increase the count by one and decrease num by one (Line 15 -16).

Answer:

The appropriate answer to the question is option A, Wired Equivalent Privacy (WEP).

Explanation:

WEP (Wired Equivalent Privacy) is the security protocol detailed in the IEEE Wi-Fi (Wireless Fidelity) standard 802.11b, which aims to offer a Wireless Local Area Network (WLAN) with adequate security and privacy.

Wardriving refers to the practice in which individuals search for Wi-Fi (Wireless Fidelity) networks while traveling in a vehicle using devices like PDAs (Personal Digital Assistants), smartphones, or portable computers.

Answer:

A business needs an Ethernet connection that spans from the northern part of their office to the southern part. The distance of this connection is 161 meters and should support speeds up to 10 Gbps in full duplex mode. Which cable types would be suitable for these specifications?

ANSWER: Multi-mode fiber optic cable should be used

Explanation:

MULTI-MODE FIBER OPTIC CABLE

For distances extending to 100 meters, Copper CATX cable is adequate. However, since the distance here is 161 meters, an Ethernet extension is necessary. Using fiber optic cable along with a media converter allows for the transition from copper Ethernet lines to fiber. Multi-mode fiber supports distances up to 550 meters for 10/100/1000 Ethernet links.

Typically, multi-mode fiber is used for short-distance communication like inside buildings or across campuses. It can achieve data rates of up to 100 Gbps, well above the requirements here. Furthermore, this option is cost-effective compared to single-mode fiber optic cables. Fiber optic technology is also advantageous due to its immunity to electromagnetic interference, voltage spikes, ground loops, and surges, making it a better choice for this application.
