Answer:

In Python:

def main():

   n = int(input("List items: "))

   mylist = []

   for i in range(n):

       listitem = input(", ")

       if listitem.isdecimal() == True:

           mylist.append(int(listitem))

       else:

           mylist.append(listitem)

   print(game_of_eights(mylist))

def game_of_eights(mylist):

   retVal = "False"

   intOnly = True

   for i in range(len(mylist)):

       if isinstance(mylist[i],int) == False:

           intOnly=False

           retVal = "Please, enter only integers"

       if(intOnly == True):

           for i in range(len(mylist)-1):

               if mylist[i] == 8 and mylist[i+1]==8:

                   retVal = "True"

                   break

   return retVal

if __name__ == "__main__":

   main()

Explanation:

The main begins here

def main():

This gets the number of list items from the user

   n = int(input("List items: "))

This declares an empty list

   mylist = []

This iterates through the number of list items

   for i in range(n):

This gets input for each list item, separated by comma

       listitem = input(", ")

Checks for string and integer input before inserting item into the list

       if listitem.isdecimal() == True:

           mylist.append(int(listitem))

       else:

           mylist.append(listitem)

This calls the game_of_eights function

   print(game_of_eights(mylist))

The game_of_eights function begins here

def game_of_eights(mylist):

This initializes the return value to false

   retVal = "False"

This initializes a boolean variable to true

   intOnly = True

This following iteration checks if the list contains integers only

   for i in range(len(mylist)):

If no, the boolean variable is set to false and the return value is set to "integer only"

       if isinstance(mylist[i],int) == False:

           intOnly=False

           retVal = "Please, enter only integers"

This is executed if the integer contains only integers

       if(intOnly == True):

Iterate through the list

           for i in range(len(mylist)-1):

If consecutive 8's is found, update the return variable to True

               if mylist[i] == 8 and mylist[i+1]==8:

                   retVal = "True"

                   break

This returns either True, False or Integer only

   return retVal

This calls the main method

if __name__ == "__main__":

   main()

Answer:

mysql

Explanation:

try building mysql database

Answer:

A. 31 bits

B. 13 bits, 18 bits

C. 256k

Explanation:

A.

We have total size of physical memory as 2gb

This means that 2¹ x 2³⁰

Using the law of indices,

= 2³¹

So physical address is equal to 31 bits

B.

We get page size = 8kb = 2³

1 kb = 2¹⁰

2³ * 2¹⁰ = 2¹³

So page replacement = 13 bits

Page frame number

= physical address - replacement bits

= 31 - 13

= 18 bits

C.

The number of frames is given as

2¹⁸ = 2⁸ x 2¹⁰ = 256K

So number of frames = 256K

D

Logical add space is 256K

Page size= physical pages = 8kb

Logical address layout= 28biys

Page number = 15 bits

Displacement = 12 bits

256k/8k = 32 pages in address space process

Answer:

This address is by default a class c network

Explanation:

This IP address in this question is a class c network because it has 196 as its first octet. A class c network is one which has its first octet to be between 192 and 223. the class c network begins with a 110 binary.  If ip is between 192 to 223 it belongs to this class. These first 3 octets are the representation of the network number in the address. Class c's were made to support small networks initially.

Answer:

In computer programming, a return statement causes execution to leave the current subroutine and resume at the point in the code immediately after the instruction which called the subroutine, known as its return address. The return address is saved by the calling routine, today usually on the process's call stack or in a register. Return statements in many languages allow a function to specify a return value to be passed back to the code that called the function.

An expression that returns a value is known as a​ function. Check more about function  below.

A function is often seen as a kind of expression or rule, or law that often tells more about a relationship.

Explanation:

An instruction set architecture (ISA) can be defined as series of native memory architecture, instructions, addressing modes, external input and output devices, virtual memory, and interrupts that are meant to be executed by the directly.

Basically, this set of native data type specifies a well-defined interface for the development of the hardware and the software platform to run it.

The two (2) main types of architectural design for the central processing unit (CPU) are;

I. Complex instruction set computing (CISC): it allows multi-step operation or addressing modes to be executed within an instruction set. Thus, many low-level operations are being performed by an instruction.

II. Reduced instruction set computing (RISC): it allows fixed length instructions and simple addressing modes that can be executed within a clock cycle.

All of the following statements are true about RISC (Reduced instruction set computing) because they are its advantages over complex instruction set computing (CISC);

a. RISC (Reduced instruction set computing) architecture has a set of instructions, so high-level language compilers can produce more efficient code.

b. It allows freedom of using the space on microprocessors because of its simplicity.

c. Many RISC processors use the registers for passing arguments and holding the local variables.

d. RISC functions use only a few parameters, and the RISC processors cannot use the call instructions, and therefore, use a fixed length instruction which is easy to pipeline.

The options that are true about RISC (Reduced instruction set computing) is; E: all of the above

Answer:

5/ 18

Explanation:

Given :

List A: [20,10,20]

List B: [40,10,30,20,40,30]

Chance that number drawn from list A is larger than or equal to that drawn dlfrom list B.

If:

A = 20

B ≤ 20 : [10,20] = 2

A = 10

B ≤ 10 : [10] = 1

A = 20

B ≤ 20 : [10,20] = 2

Probability = Required outcome / Total possible outcomes

Hence,

required outcome = (2 + 2 +1) = 5

Total possible outcomes = 3C1 * 6C1 = (3 * 6) = 18

Hence,

chance that the number we drew from list A is larger than or equal to the number we drew from list B

= 5 / 18

In this exercise we have to use the knowledge in computational language in python to describe a code that best suits, so we have:

Explanation:

The following code was written in Java and follows all of the instructions provided. Some instructions were most likely written incorrectly as following them made no sense and would not allow the program to run. Such as placing the main method code into the encryptString method. Since the code inside the main method needed to stay inside the main method for the program to function accordingly. The code that most likely needed to be moved was the EncryptText code to the encryptString method.

package sample;

import java.util.Scanner;

class EncryptTextMethods {

   private static String encryptMessage(String message) {

       //convert string to character array

       char stringChars[] = message.toCharArray();

       //for each character

       for(int i=0; i< stringChars.length; i++) {

           char ch = stringChars[i];

           //if character within range of alphabet

           if(ch <= 'z' && ch >= 'a') {

           //obtain the character value

           //add 1 to the integer value

           //enter modulus by 26 since z will become a

           //once again add the remainder to 'a'

               stringChars[i] = (char)('a' + ((int)(ch - 'a') + 1) % 26 );

           }

       }

       //construct the string message

       return String.valueOf(stringChars);

   }

   public static String decryptString(String message) {

       char stringChars[] = message.toCharArray();

       String decrypted = "";

       for (int x = 0; x < stringChars.length; x++) {

           int charValue = stringChars[x];

           decrypted += String.valueOf( (char) (charValue - 1));

       }

       return decrypted;

   }

   public static void main(String[] args) {

       Scanner keyboard = new Scanner(System.in);

       System.out.println("Please enter text to encode: ");

       String message = keyboard.nextLine();

       message = message.toLowerCase();

       String encrypted = encryptMessage(message);

       String decrypted = decryptString(encrypted);

       System.out.println("Original Message: " + message);

       System.out.println("Encrypted: " + encrypted);

All traffic is encrypted. No one on your network can see what is going on (except for knowing where those packets are going to).

The identity of the remote server can be verified using certificates. So you also know that it really is your bank that you are talking to.

Optionally (and not in wide-spread use), the identity of the client can also be verified using certificates. This would allow for secure login to a site using chip cards instead of (or in addition to) password

Hyper Text Transfer Protocol (HTTP) and Secure HTTP are the same protocol from a standpoint of passing or blocking them with a firewall is false.

Basic HTTP (Hyper Text Transfer) is the Characteristics. It has the protocol that has enables communication in between web browsers and the servers. It has the protocol for the requests and answers. By default, it connects to the secure TCP connections on port 80.

Hypertext Transfer Protocol Secure (HTTPS) is an add-on to the Hypertext Transfer Protocol. It has been used for safe communication over a computer network and is widely used on the Internet. In HTTPS, the transmit protocol is encrypted using Transport Layer Security(TLS) or, formerly, Secure Sockets Layer(SSL).

The difference between HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses. HTTPS is the secure version of HTTP, which is the primary protocol used to send data between a web browser and a website.
