Answer: Transmission rate

Explanation:

Transmission rate is measured in bits per second and it transmitted the data at the different rate across the circuit. The speed in which the data rate is transferred from one device to anther is known as transmission rate.

The transmission rate are always less as compared to signalling rate because the signalling rate contain the total data which basically include the overhead to control the information.

Therefore, transmission rate is the correct option.

Complete the method/function so that it converts dash/underscore delimited words into camel casing. The first word within the ou

nata0808 [166]

Answer:

I am writing a Python program. Let me know if you want the program in some other programming language.

def toCamelCase(str):

string = str.replace("-", " ").replace("_", " ")

string = string.split()

if len(str) == 0:

return str

return string[0] + ''.join(i.capitalize() for i in string[1:])

print(toCamelCase("the-stealth-warrior"))

Explanation:

I will explain the code line by line. First line is the definition of toCamelCase() method with str as an argument. str is basically a string of characters that is to be converted to camel casing in this method.

string = str.replace("-", " ").replace("_", " ") . This statement means the underscore or dash in the entire are removed. After removing the dash and underscore in the string (str), the rest of the string is stored in string variable.

Next the string = string.split() uses split() method that splits or breaks the rest of the string in string variable to a list of all words in this variable.

if len(str) == 0 means if the length of the input string is 0 then return str as it is.

If the length of the str string is not 0 then return string[0] + ''.join(i.capitalize() for i in string[1:]) will execute. Lets take an example of a str to show the working of this statement.

Lets say we have str = "the-stealth-warrior". Now after removal of dash in by replace() method the value stored in string variable becomes the stealth warrior. Now the split() method splits this string into list of three words the, stealth, warrior.

Next return string[0] + ''.join(i.capitalize() for i in string[1:]) has string[0] which is the word. Here join() method is used to join all the items or words in the string together.

Now i variable moves through the string from index 1 and onward and keeps capitalizing the first character of the list of every word present in string variable from that index position to the end. capitalize() method is used for this purpose.

So this means first each first character of each word in the string starting from index position 1 to the end of the string is capitalized and then all the items/words in string are joined by join() method. This means the S of stealth and W of warrior are capitalized and joined as StealthWarrior and added to string[0] = the which returns theStealthWarrior in the output.

Write a method called removeHighPrice that will go through a provided ArrayList called prices and removes the first price that i

Diano4ka-milaya [45]

Answer:

The method written in Java is as follows:

public static ArrayList<Double> removeHighPrice (ArrayList<Double> prices){

for(int i =0;i<prices.size();i++){

if(prices.get(i) > 5.00){

prices.remove(i);

break;

}

return(prices);

}

Explanation:

This line declares the method

public static ArrayList<Double> removeHighPrice (ArrayList<Double> prices){

This line iterates through the ArrayList named prices

for(int i =0;i<prices.size();i++){

This checks if current price is greater than 5

if(prices.get(i) > 5.00){

If yes, the price is removed

prices.remove(i);

And the loop is terminated

break;

}

This returns the ArrayList

return(prices);

}

FS and GS are two___________________ in protected mode.

masha68 [24]

Answer:

Segment registers

Explanation:

The initial purpose behind the segment registers was to enable a program to access many distinct (big) memory sections designed to be autonomous and part of a constant virtual store.

They don't have a processor-defined objective, but instead Operating system runs them for purpose. The GS register is used in Windows 64-bit to point to constructions defined by the operating scheme. Operating system kernels usually use FS and GS to access thread-specific memory. In windows, thread-specific memory is managed using the GS register. To access cpu-specific memory, the linux kernel utilizes GS.
