You have a notebook computer and wish to connect to an IEEE 802.11ac wireless network. The computer does not have a built-in WLA

N card or a PC card interface. You do not want any peripherals connected to the notebook that use wires and do not want to disassemble the computer. Which wireless adapter would be the best solution?A. Wireless PCI
B. Wireless PCMCIA
C. Wireless Full Mini-PCIe
D. Wireless USB 2.0

Answer:

Wireless USB 2.0

Explanation:

USB ports are available in all modern notebook computers. This makes the wireless USB 2.0 adapter a capable option to solve the network issue.

Wireless USB 2.0 can send 480Mbit/s and 110Mbit/s at a 3meters and 10 meters respectively, it frequency ranges from 3.1GHz to 10.6GHz.

In cases where the internal wireless card is faulty or the computer does not come with a wireless chip inside, the Wireless USB 2.0 is the right option for you to be able to connect over a network efficiently.

<u>Paired programming:</u>

Paired programming is a new technique where one person gets one another to<em> write the code</em>. Here one will write the code and other will start verifying as the type.

So we might think it is waste to employ two person for same task but it is not so. There are many <em>benefits in incorporating this technique</em>. Let us see those benefits one by one.

  • <em>Inter-personal skill gets improved </em>
  • <em>Lower amount of coding mistake </em>
  • <em>Learn from each other </em>
  • <em>Peer review enhance collaboration </em>

Challenges expect to arise during pair-programming

  • Two heads are superior to one. On the off chance that the driver experiences a <em>hitch with the code</em>, there will be two of them who'll take care of the issue.  
  • Builds up your <em>staff's relational aptitudes</em>. Working together on a solitary venture encourages your group to welcome the estimation of <em>correspondence and collaboration.  </em>

Overcome Method

The most ideal approach to move <em>toward blending</em> is to accomplice two software engineers and have them share a PC. The pair ought to have the option to choose how to part the work, and it is prudent that they should <em>switch jobs frequently.</em>

why is it useful to learn how to solve and program solutions with a limited set of command in computer science
12345 [234]

Answer:

Give at least one reason why it's useful to learn how to solve and program solutions with a limited set of commands. So that when there is more commands we know how to use the ones we have. parameters help generalize the solution to a specific problem. how are functions with parameters an example of abstraction?

) Consider a router that interconnects four subnets: Subnet 1, Subnet 2, Subnet 3 and Subnet 4. Suppose all of the interfaces in
erik [133]

Answer:

Check the explanation

Explanation:

223.1.17/24 indicates that out of 32-bits of IP address 24 bits have been assigned as subnet part and 8 bits for host id.

The binary representation of 223.1.17 is 11011111 00000001 00010001 00000000

Given that, subnet 1 has 63 interfaces. To represent 63 interfaces, we need 6 bits (64 = 26)

So its addresses can be from 223.1.17.0/26 to 223.1.17.62/26

Subnet 2 has 95 interfaces. 95 interfaces can be accommodated using 7 bits up to 127 host addresses can represented using 7 bits (127 = 27)

and hence, the addresses may be from 223.1.17.63/25 to 223.1.17.157/25

Subnet 3 has 16 interfaces. 4 bits are needed for 16 interfaces (16 = 24)

So the network addresses may range from 223.1.17.158/28 to 223.1.17.173/28

Write a function analyze_text that receives a string as input. Your function should count the number of alphabetic characters (a
laiz [17]

Answer:

def analyze_text(sentence):

   count = 0

   e_count = 0

   for s in sentence:

       s = s.lower()

       if s.isalpha():

           count += 1

       if s == "e":

           e_count += 1

   return "The text contains " + str(count) + " alphabetic characters, of which " + str(e_count) + " (" + str(e_count*100/count) + "%) are ‘e’."

Explanation:

Create a function called analyze_text takes a string, sentence

Initialize the count and e_count variables as 0

Create a for loop that iterates through the sentence

Inside the loop, convert all letters to lowercase using lower() function. Check each character. If a character is a letter, increment the count by 1. If a character is "e", increment the e_count by 1.

Return the count and e_count in required format

Write a bool function isPalindrome that takes one string parameter and returns true if that string is a palindrome and false oth
kkurt [141]

Answer:

Here is the bool function isPalindrome:

bool isPalindrome(string s)

{  bool palindrome;      

 int j;

 int len = s.length();

 for (int i =0, j= len-1; i < len/2; i++, j--)  

   if (s[i] == s[j])

     palindrome = true;  

   else

     palindrome = false;

 return palindrome; }

Explanation:

The bool function isPalindrome takes a string as parameter and returns true if the string is a palindrome or false if the string is not palindrome. The string variable s holds the string value. In function isPalindrome, there is a bool type variable palindrome. bool is a data type which is used to hold values true or false which is then stored in the palindrome variable.

Next it is being found that how many characters are there in the input string using length() function which returns the length of the string. The length of the string is stored in int type variable len.

Next the for loop starts which has two variables i and j where i starts at 0 position of the input string and j starts at the last position of the string. These two variables move or traverse along the string this way. i variable stops when half the length of the input string is reached. At the end of every iteration i moves forward by the increment of its value to 1 and j moves backwards by the decrement  of its value to 1.

Every the body of  the loop executes, there is an if condition in the body of the loop which checks if the string is a palindrome. This is checked by matching the character at position/index i with the character at position j of the string. This will continue character by character until the i reached half the length of the input string and if every character in i was matched to every character in j then palindrome = true; statement is executed which returns true as the string is a palindrome otherwise palindrome = false; is returned as the string is not a palindrome.

For taking input string from the user and to check if the function isPalindrome() works correctly a main() function is written which takes input string from the user and reads in variable str calls isPalindrome() function. If the string is palindrome then the cout statement in main() function prints the message: String is a palindrome and if the input string is not a palindrome the the following message is displayed in the output screen: String is not a palindrome

int main()

{

string str;

cout<<"Enter a string: ";

cin>>str;

if(isPalindrome(str))

cout<<"String is a palindrome";

else

cout<<"String is not a palindrome";

}

The screenshot of the program along with the output is attached.
