Explanation:

FCC is the abbreviation for The Federal Communications Commission (United States Federal Communication Commission). It is, as a rule, an administrative area. It is a free Federal administrative office of the United States government dependable straightforwardly to Congress, built up by the Communications Act and made by resolution to manage interstate and worldwide interchanges by radio, TV, wire, satellite, and link. It includes an investigation on pending changes in the remote world.

FCC certainly has consequences for the present status of 5 GHz Bridging Spectrum. As far as possible one of the U-NII groups which can be utilized outside with the 5.725-5.825 band which is perfect fitting open air tasks. The 2.4 GHz ISM band might be utilized outside where the yield power at the purposeful radiator can't surpass 1 watt. In the United States, the FCC manages the frequencies utilized, the yield power levels, and the open air utilization restrictions.

There is an effect of the FCC 5 GHz U-NII report and a request on Wi-Fi Networks. FCC's activities are to change some specialized principles for the 5 GHz U-NII groups. The specialized change that is affirmed is - U-NII 1 band (5.150 - 5.250 GHz) indoor activity limitation being evacuated permitting utilization of the band for open air hotspots, WISPs, and scaffold joins. There will be a development of open hotspots profiting by this change. The FCC considers 11 channels under the Operating Frequencies.

The FCC has characterized UNII-2 and UNII-3 groups, the two of which had four channels. The channels were divided 20 MHz separated with a RF range data transmission of 20 MHz giving non-covering channels utilizing 20 MHz channel width.

The UNII-2 band was assigned additionally for open air tasks and allowed outside recieving wires. The UNII-3 band was proposed for open air connect items and allowed outer radio wires, however the UNII-3 band is likewise utilized for outside 802.11a/n/air conditioning WLANs.

FCC (America) underpins Operating Frequency Range for 802.11b and 802.11g on Center Frequency: 2412, 2417, 2422, 2427, 2432, 2437, 2442, 2447, 2452, 2457, 2462. FCC has delivered an amendment to the guidelines covering the 5 GHz 802.11a channel utilization. This correction has included 11 extra channels, carrying the accessible channel's ability to 23 channels.

As far as possible your complete force yield by utilizing a sliding scale when you set up a significant distance Wi-Fi connect. The scale really begins at 30 dBm of enhancement power utilizing a 6 dBi directional reception apparatus. For each 1 dBm drop in enhancement power, there would be an expansion in the intensity of directional radio wire by 3 dBi. The FCC permits this sliding scale since when you utilize a bigger highlight point radio wire, your shaft example will cover less territory and cause less impedance for other people.

Answer:

c. 20

Explanation:

The program works as following:

x is initialized to 10

y is initialized to 30

if (x < 0) statement checks if the value of x is less than 0. This condition evaluates to false because x=10 so 10 is greater than 0. So the statement inside the body of this if condition will not execute. Hence the program control moves to the else if part:

else if (x < 10) statement checks if the value of x is less than 10. This condition evaluates to false because x=10 so x is equal to 10 and not less than 10. So the program control moves to the else part and the statement in else part executes:

else {

y = 20;

}

This statement in else part assigns the value 20 to y

Then the program control moves to the following statement:

cout << y;

This statement prints the value of y. As the else part assigns 20 to y so the output is:

20

Answer:

D. Remote server public key

E. OCSP

Explanation:

Options D and E are correct because the above question states that its "verifying that a key is valid". This means that it didn't specify which key. Therefore, it sensible that the application wants to verify the validity of the remote host's key. So, in order to use OCSP to verify the validity of that key, that app actually needs the public key of the remote server.

Options :

The domain name is registered to someone else.

Domain names must end in ".com".

You are not the legal owner of ABC Company.

Domain names must be all in lowercase.

Answer:

The domain name is registered to someone else.

Explanation: In the scenario above, ABCcompany.org represents the domain name of a particular person or establishment which provides access to the website of the owner. The domain name given to an individual or website must be distinct, that is no two different organizations or persons can use exactly the same domain name. Domain names can end with :. com, org, ng and various other and they aren't case sensitive. Therefore, the inability to register the domain name abive will likely stem from the fact that the domain name has is already registered to someone else.

The domain of a website is the name of the website. The most likely reason why the domain cannot be registered is that, it has already been registered/taken by someone else.

There are several reasons why a domain cannot be registered.

The most important reason is that:

When a domain is taken, no other person can have access to that domain until its expiry (and not renewed). So, when a domain has been taken, you will not be able to register such domain.

Another reason is that:

Insufficient funds is another reason, if the domain is not a free domain.

Answer:

Here is the complete member function:

void CablePlan::SetNumDays(int numDays) {   //member function of class CablePlan which take numDays as parameter

this->numDays = numDays;   // refers to the fields numDays of CablePlan  class using this keyword

return;  }

Explanation:

The complete program is:  

#include <iostream>  //to use input output functions

using namespace std; //to identify objects like cin cout

class CablePlan{  //class

public:  //public methods of class

void SetNumDays(int numDays); //method of class CablePlan that takes numDays as parameter to set the days

int GetNumDays() const;  // method of class CablePlan to get no of days

private:  //private data member of class CablePlan

int numDays;  //private data member of class CablePlan that holds no of days

};

// FIXME: Define SetNumDays() member function, using "this" implicit parameter.

void CablePlan::SetNumDays(int numDays) { /

this->numDays = numDays;     // used to refer to numDays variable of CablePlan class using this keyword

return;}  

int CablePlan::GetNumDays() const {  //define member function GetNumDays

return numDays;}  

int main() {  //start of main function

CablePlan house1Plan;  //creates object of CablePlan class

house1Plan.SetNumDays(30);  //uses object to call member function of  CablePlan passing value 30 to it in order to set no of days

cout << house1Plan.GetNumDays() << endl;  //uses object to call member function of  CablePlan to get the no of days (numDays)

return 0;}

Here this keyword is used to refer to the field i.e. numDays of CablePlan class. This distinguishes local member numDays  from parameter numDays using this with -> symbol.  

'this' pointer retrieves the object's numDays  which is hidden by the local variable numDays . The output of this program is:

Explanation:

The above program first prompts the user to enter two numbers. Here the data type of two number is float in order to accept floating numbers. The switch statement contains cases which execute according to the choice of user. The choice available to user is: 1,2,3,4 and 5

If the user selects 1 then the case 1 executes which calls the method add. The method add takes two numbers as parameters, adds the two numbers and returns the result of the addition. This result is displayed on output screen. However if the result of addition is a negative number then the message: "Oops option 1 is returning the negative number that is:" is displayed on the screen along with the negative answer of that addition.

If the user selects 2 then the case 2 executes which calls the method sub. The method works same as add but instead of addition, sub method takes two numbers as parameters, subtracts them and returns the result of the subtraction.

If the user selects 3 then the case 3 executes which calls the method mul. The method mul takes two numbers as parameters, multiplies them and returns the result of the multiplication.

If the user selects 4 then the case 4 executes which calls the method div. The method div takes two numbers as parameters and checks if the denominator i.e. second number is 0. If its 0 then Division by 0 message is displayed along with result i.e. infinity. If second number is not 0 then method divides the numbers and returns the result of the division.

If the user selects 5 then the case 5 executes which calls the method average. The average method then  asks the user to enter two more numbers first2 and second2 and takes the sum of all four numbers i.e. first, second, first2 and second2. Then the result of sum is divided by 4 to compute average. The method returns the average of these four numbers.

Answer:

Two bits would be not enough.

Four bits would be enough.

Explanation:

With two bits, only 4 unique binary numbers are available. They are:

00

01

10

11

And since there are 5 lowercase vowel letters and 5 uppercase vowel letters in the English language, making a total of 10 vowel letters, two bits will only cater for 4 of the 10 letters and as such will not be enough.

With three bits, only 8 unique binary numbers are available. They are:

000

001

010

011

100

101

110

111

Three bits will therefore only cater for 8 of the 10 letters and as such will not be enough.

With four bits however, there are 16 binary numbers available. They are:

0000

0001

0010

0011

0100

0101

0110

0111

1000

1001

1010

1011

1100

1101

1110

1111

Four bits are more than enough to cater for all the 10 vowel letters in the English language.

PS: The number of unique binary numbers that can be found in n bits is given by;

2ⁿ

So;

If we have 3 bits, number of unique binary numbers will be

2³ = 8

If we have 6 bits, number of unique binary numbers will be

2⁶ = 64

Using bits concepts, it is found that two bits is not enough to assign a binary number to each vowel in the English language, as two bits can represent at most 4 symbols, and there are 5 vowels.
