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.
When a Select Case statement executes, the value of the test expression is compared with the values that follow each of the _______ keywords.
Answer:
Case
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
A Select Case statement can be defined as a conditional statement that avails software developers or programmers the ability to test a variable by comparing it with a list of values.
In a Select Case statement, each variable is referred to as a Case.
Generally, when a Select Case statement executes, the value of the test expression is compared with the values that follow each of the Case keywords.
LAB: Parsing food data in C++
Write the code in c++
Given a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate arrays, and outputs the available food items in the following format: name (category) -- description
Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character ('\t').
Hints: Use the find() function to find the index of a tab character in each row of the text file. Use the substr() function to extract texts separated by the tab characters.
Ex: If the input of the program is:
food.txt
and the contents of food.txt are:
Sandwiches Ham sandwich Classic ham sandwich Available
Sandwiches Chicken salad sandwich Chicken salad sandwich Not available
Sandwiches Cheeseburger Classic cheeseburger Not available
Salads Caesar salad Chunks of romaine heart lettuce dressed with lemon juice Available
Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available
Beverages Water 16oz bottled water Available
Beverages Coca-Cola 16oz Coca-Cola Not available
Mexican food Chicken tacos Grilled chicken breast in freshly made tortillas Not available
Mexican food Beef tacos Ground beef in freshly made tortillas Available
Vegetarian Avocado sandwich Sliced avocado with fruity spread Not available
the output of the program is:
Ham sandwich (Sandwiches) -- Classic ham sandwich
Caesar salad (Salads) -- Chunks of romaine heart lettuce dressed with lemon juice
Water (Beverages) -- 16oz bottled water
Beef tacos (Mexican food) -- Ground beef in freshly made tortillas

Write a program that asks a user to enter a date in month day year format (for example 10 12 2016) and displays the day of the week for that date, in this case, Wednesday.
Answer and Explanation:
Using javascript:
function dayof_theweek(){
var TodayDate = window. prompt("enter today's date in the format 'year, month, day' ");
var Datenow=new date(TodayDate);
var Dayofweek=Datenow.getday();
var Days=["monday","Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"];
if(Dayofweek==indexOf(Days[Dayofweek]))
{
document.createTextnode(Days[Dayofweek]);
}
}
The program above uses a date object which uses the method getday to get the day of the week(get day returns an integer from 0 to 6).we then use a comparison operator == to test the condition that returned value Dayoftheweek is same with the index of the array Days and then print to a html document. The program may need improvements such as the fact that errors may arise when proper input isn't given, and therefore must be handled.

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.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter number 1: ");
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));
}
public static int LargestNumber(int num1, int num2, int num3) {
int max = num1;
if (num2 > num1) {
max = num2;
}
if (num3 > max) {
max = num3;
}
return max;
}
public static int SmallestNumber(int num1, int num2, int 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:
INPUTS
Integers num1, num2, num3;
OUTPUTS
Integers min, max;
MAIN ALGORITHM
Print "Write the first integer";
Write num1;
Print "Write the second integer";
Write num2;
Print "Write the third integer";
Write num3;
min = SmallestNumber(num1, num2, num3);
max = LargestNumber(num1, num2, num3);
Print "The smallest of the three input values is " min;
Print "The largest of the three input values is " max;
FUNCTION SmallestNumber()
if (((num1 <= num2) and (num2 <= num3)) or ((num1 <= num3) and (num3 <= num2))) then:
min = num1;
else if (((num2 <= num1) and (num1 <= num3)) or ((num2 <= num3) and (num3 <= num1))) then:

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.

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".

Answer:
in the body part of the declaration or definition
Explanation:
In functional programming the scope of a variable is in the body part of the declaration or definition. Meaning that as soon as it is declared, whatever body it is in can call and use that variable but not any code outside of that body. For example, in the below code variable (var1) is declared inside func1 and therefore can be used by any code inside the body of func1 but not by code inside func2 since it is outside the body of func1.
void func1() {
int var1;
}
void func2() {
var1 = 2 // This will not work, since var1 is only available in func1()
