A small e-commerce company uses a series of Robotic Process Automation solutions to manage the backup of data from individual workstations to an on-premise server. However, the company is opening another office and would like to more easily share data between locations, along with better protecting the data from loss.
Which technology could be combined with their current automated processes to do this?
Answer:
Cloud.
Explanation:
Cloud computing can be defined as a form of data computing which requires the use of shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offer individuals and businesses a fast, secured, effective and efficient way of providing services over the internet.
Basically, cloud computing comprises three (3) service models and these include;
1. Platform as a Service (PaaS).
2. Software as a Service (SaaS).
3. Infrastructure as a Service (IaaS).
Additionally, the two (2) main characteristics of cloud computing are;
I. Measured service: it allows cloud service providers to monitor and measure the level of service used by various clients with respect to subscriptions.
II. Resource pooling: this allows cloud service providers to serve multiple customers or clients with services that are scalable and provisional.
For example, the provisioning of On-demand computing resources such as storage, network, virtual machines (VMs), etc., so as to enable the end users install various software applications, database and servers.
Hence, the technology that could be combined by the small e-commerce company with its current automated processes is cloud storage.
There are different tools used in data sharing. The technology that could be combined with their current automated processes to do this is blockchain.
Blockchain is known to use different kinds of distributed ledger that is often shared across networked devices. Through this, people on the network can share files and values securely and even on a peer-to-peer basis. This is no need any middlemen.
Data protected in blockchain is very vital. All records on a blockchain are known too be secured through the act of cryptography. Here, Network people do have their own private keys that are given to them for any transactions they make.

The Burger Doodle restaurant chain purchases ingredients from four different food suppliers. The
company wants to construct a new central distribution center to process and package the ingredients it uses in its menu items before shipping them to their various restaurants. The suppliers
transport the food items in 40-foot tractor-trailer trucks. The coordinates of the four suppliers and the annual number of truckloads that will be transported to the distribution center are as follows:
Coordinates
Supplier x y Annual Truckloads
A 200 200 65
B 100 500 120
C 250 600 90
D 500 300 75
Determine the set of coordinates for the new distribution center that will minimize the total miles traveled from the suppliers
Answer :
Given Information:
Site 1: x1 = 360 , y1 = 180
Site 2: x2 = 420 , y2 = 450
Site 3: x3 = 250 , y3 = 400
Solution:
Xa = 200, Ya = 200, Wa = 75
Xb = 100, Yb = 500, Wb = 105
Xc = 250, Yc = 600, Wc = 135
Xd = 500, Yd = 300, Wd = 60
If centre of gravity is (x,y)
then x = (200*75+100*105+250*135+500*60)/(75+105+135+60)
x = 238
then y = (200*75+500*105+600*135+300*60)/(75+105+135+60)
y = 444
Using centre-of-gravity method, location of distribution centre = (238,444) Using rectilinear distance,
Load distance score of Site 1: 75*(abs(360-200)+abs(180-200))+105*(abs(360-100)+abs(180-500))+135*(abs(360-250)+abs(180-600))+60*(abs(360-500)+abs(180-300)) = 161550
Load distance score of Site 2: 75*(abs(420-200)+abs(450-200))+105*(abs(420-100)+abs(450-500))+135*(abs(420-250)+abs(450-600))+60*(abs(420-500)+abs(450-300)) = 131100
Load distance score of Site 3: 75*(abs(250-200)+abs(400-200))+105*(abs(250-100)+abs(400-500))+135*(abs(250-250)+abs(400-600))+60*(abs(250-500)+abs(400-300)) = 93000
Site 3 tends to be optimal as it offers a lower distance ranking.
I HOPE THIS IS RIGHT AND IT HELPS !!!!!

Define a function named LargestNumber that takes three integers as parameters and returns the largest integer. Define a second function named SmallestNumber that takes three integers as parameters and returns the smallest integer. Then, write a main program that reads three integers as inputs, calls functions LargestNumber() and SmallestNumber() with the inputs as arguments, and outputs the largest and the smallest of the three input values. CORAL
Answer:
Explanation:
The following code is written in Java and creates both of the requested methods. The methods compare the three inputs and goes saving the largest and smallest values in a separate variable which is returned at the end of the method. The main method asks the user for three inputs and calls both the LargestNumber and SmallestNumber methods. The output can be seen in the attached image below.

int num1 = in.nextInt();
System.out.println("Enter number 2: ");
int num2 = in.nextInt();
System.out.println("Enter number 3: ");
int num3 = in.nextInt();
System.out.println("Largest Value: " + LargestNumber(num1, num2, num3));
System.out.println("Smallest Value: " + SmallestNumber(num1, num2, num3));

int smallest = num1;
if (num2 < num1) {
smallest = num2;
}
if (num3 < smallest) {
smallest = num3;
}
return smallest;
}
}
The algorithm consists in a main routine that calls two functions based on if-cycles to determine the minimum and the maximum of a set of three integers, whose construction can revised below.
In this question we must define a main algorithm in which three integers are introduced and functions LargestNumber() and SmallestNumber() are called and outputs are printed:

Daniella is configuring a Wi-Fi network in a restaurant for access by staff and customers. How far does WiFi, the broadband wireless technology that allows computers and other devices to communicate over a wireless signal typically travel indoors in the form of radio waves?
a. 1000 feet
b. 300 feet
c. 120 feet
d. 500 feet
Answer:
c. 120 feet
Explanation:
WiFi can be defined as a wireless local area network that allows network devices such as access points (APs), computers (both laptops and desktops), smartphones, smart televisions, etc., to communicate with each other wirelessly over a short-ranged network. It is a standard communication network that uses radio waves to establish a channel (medium) between multiple network devices.
This ultimately implies that, the network range or distance covered by WiFi is largely dependent on transmission power and frequency. The standard range or distance covered by WiFi is about 50 meters (160 feet).
Hence, a WiFi traveling indoors in the form of radio waves and operating on the 2.4 GHz band would cover up to a distance of 150 feet. Also, a WiFi can reach or travel up to 300 feet outdoors.
In this scenario, the WiFi network Daniella is configuring in a restaurant for access by staff and customers can go as far as 120 feet indoors.

To use AutoSum with a row of four values, where must your cursor be to have the sum appear in the row if you have not highlighted the cells?
Answer:
on the first empty cell to the right of the last cell containing a value.
Explanation:
The AutoSum function in excel gives a shortcut path to taking the sum of numeric values in a row or column of data. The Autosum uses the sum function to take the addition of all the desired rows or columns values without needing to make a manual highlight of the data. To use AutoSum with a row of 4 values, the cursor must be placed immediately at the cell next 4th row cell containing a value. This is equivalent to the first empty cell to the right of the last cell containing a value, then autosum is clicked in the home tab and all 4 cells will be highlighted as it uses the sum function to calculate the sun of the 4 row values.
The Autosum Excel function could be made accessible with ALT+ the = sign, and the formula is automatically created to add a continuous range of all numbers.
The AutoSum function in Excel provides a shortcut to the sum of numerical values in a data line or column. To add all the desired lines or column values the Autosum uses the total function without having to make a manual highlight. The cursor must immediately be placed in the fourth cell next row containing a value to use AutoSum with a round of 4 values. The first empty cell to the right of the latter cell with a value is equal to that of the auto-sum, then the domestic tab clicks on auto-sum, and the sum function is used to calculate the sun of the four-row values to highlight all 4 cells.Therefore, the final answer is "on the first empty cell to the right side of the last cell with value".
