Answer:

Processor P2 has the highest performance expressed in instructions per second.

Explanation:

Given:

Processors:

P1

P2

Clock rate of P1 = 3 GHz

Clock rate of P2 = 3 GHz

Cycles per instruction = CPI of P1 = 1.5

Cycles per instruction = CPI of P2 = 1.0

To find:

which processor has the highest performance in instructions per second (IPS)

Solution:

Compute CPU time:

CPU time =  (Number of instructions * cycles per instruction) / clock rate

CPU time = (I * CPI) / R

We are given the CPI and clock rate. So

CPU time = (I * CPI) / R

 I / CPU time = R/CPI

Since

Instructions per second = Number of instructions (I) / execution time

                             IPS     = I / CPU time

So

Instructions Per Second = clock rate / cycles per instruction

IPS = R/CPI

Putting the values in above formula:

Instructions Per Second for P1 = IPS (P1)

                                                  = clock rate P1 / CPI (P1)

                                                  = 3 GHz / 1.5

                                     IPS (P1) = 2            

As 1 GHz = 10⁹ Hz

IPS (P1) = 2x10⁹

Instructions Per Second for P2 = IPS (P2)

                                                  = clock rate P2 / CPI (P2)

                                                  = 3 / 1.0

                                     IPS (P2) = 3

As 1 GHz = 10⁹ Hz

IPS (P2) = 3x10⁹

Hence processor P2 has the highest performance expressed in instructions per second i.e. 3x10⁹

Answer:

B. UDP 67

C. UDP 68

Explanation:

In this scenario, after a new firewall is installed, users report that they do not have connectivity to the Internet. The output of the ipconfig command shows an IP address of 169.254.0.101. The ports that would need to be opened on the firewall to allow the users to obtain an IP address are both the UDP 67 and UDP 68. UDP is an acronym for user datagram protocol in computer networking and it is part of the transmission control protocol/internet protocol (TCP/IP) suite.

Generally, the standard Internet communications protocols which allow digital computers to transfer (prepare and forward) data over long distances is the TCP/IP suite.

Also, the UDP 67 and 68 ports is responsible for the connectionless framework which is typically being used by the dynamic host configuration protocol (DHCP) that is used to assign IP addresses to various computer users and manage their leases.

UDP 67 is the destination port for a DHCP server while the UDP 68 is the port number for the computer user (client).

Hence, for the users to have access to the internet or internet connectivity both UDP 67 and 68 must be opened on the firewall.

Answer:

Here is the Python program:

import keyword  #module that contains list of keywords of python

filename = input("Enter Python source code filename: ") # prompts user to enter the filename of a source code

code = open(filename, "r") # opens the file in read mode

keywords = keyword.kwlist #extract list of all keywords of Python and stored it into keywords

dictionary = dict() #creates a dictionary to store each keyword and its number of occurrence in source code

for statement in code: # iterates through each line of the source code in the file

   statement = statement.strip() # removes the spaces in the statement of source code  

   words = statement.split(" ") #break each statement of the source code into a list of words by empty space separator

   for word in words:# iterates through each word/item of the words list  

       if word in keywords:#checks if word in the code is present in the keywords list of Python  

           if word in dictionary: #checks if word is already present in the dictionary

               dictionary[word] = dictionary[word] + 1 #if word is present in dictionary add one to the count of the existing word

           else: #if word is not already present in the dictionary  

               dictionary[word] = 1 #add the word to the dictionary and set the count of word to 1

for key in list(dictionary.keys()): #iterates through each word in the list of all keys in dictionary  

   print(key, ":", dictionary[key])# prints keyword: occurrences in key:value format of dict

Explanation:

The program is well explained in the comments attached with each line of the program.  

The program prompts the user to enter the name of the file that contains the Python source code. Then the file is opened in read mode using open() method.

Then the keyword.kwlist statement contains the list of all keywords of Python. These are stored in keywords.

Then a dictionary is created which is used to store the words from the source code that are the keywords along with their number of occurrences in the file.

Then source code is split into the lines (statements) and the first for loop iterates through each line and removes the spaces in the statement of source code .

Then the lines are split into a list of words using split() method. The second for loop is used to iterate through each word in the list of words of the source code. Now each word is matched with the list of keywords of Python that is stored in keywords. If a word in the source code of the file is present in the keywords then that word is added to the dictionary and the count of that word is set to 1. If the word is already present in the dictionary. For example if there are 3 "import" keywords in the source code and if 1 of the import keywords is already in the dictionary. So when the second import keyword is found, then the count of that keyword is increased by 1 so that becomes 2.

Then the last loop is used to print each word of the Python that is a keyword along with its number of occurrences in the file.

The program and its output is attached in a screenshot. I have used this program as source code file.

The answer is "check the worksheet is not read only"

Explanation:

The read only mode is used for read the file data, and it doesn't allows the user to update the file, and for updating the worksheet we should check iut does not open in the read-only mode.

If it is open, then we close it and for close we goto the office button and click on the tools option after that goto general setting, in this there is a check box for turn off the read-only mode.

Answer:

The technician should either provide a route from the user's IP scheme to the printer or change the user's IP scheme to be within the same scheme as the printer.

Explanation:

The most likely reason the user is unable to print to the printer is that the user's computer cannot path the current address to the address of the printer.  Without the printer being on the same subnet as the user's computer, the computer has no way of being able to tell where the printer is.

The two solutions to this are to either add a route to the user's computer explicitly telling the user's computer where to trace to find the printer or to change the user's computer to match the IP scheme of the printer.

Cheers.

Answer:

a. There are improvements in security and high availability during outage

Explanation:

Virtualization occurs when data that could be in several formats (for example, storage devices) are made to appear real through a software. There are virtualization providers who act as third-party between users and the original manufacturers of the software. While virtualization has received wide popularity in recent times because of the several advantages it offers of which cost-saving is included, it also has some disadvantages. One of them from the options provided is the possibility of a security breach and its uncertain availability.

The security breach arises because of the proliferation of information on the virtual space. This information can be accessed by unauthorized hackers. Also since third-party providers are the usual providers of virtualization services, the availability depends on them because if they shut down, users can no longer access the software.

Bit stuffing Framing Method

In the given situation, the beginning casing is shown by 6 sequential ones followed by 2 zeroes.

The beginning casings are generally known as the flags.which are utilized for demonstrating the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the reciever.

Along these lines here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).

To enable us understand how this question plays out, let us understand the rule for Stuffing and De-stuffing .

The standard for stuffing is :

At whatever point there are 5 successive ones supplement one zero in the casing which is an information. The embedded zero piece is known as the stuffed bit.The principle reason behind stuffing somewhat after 5 back to back ones is to evade the distortion of information (data) as flag. If the reciever misconstrues the information as end banner then he would quit recieving the information where the entire information sent by the sender will be left and lost causing an error-prone information.

The rule for destuffing :

The standard/rule for destuffing is only inverse as stuffing. After recieving the bitstuffed information (data), at the reciever's end zero after each 5 continuous ones will be evacuated and the rest of the information will be considered as the genuine information.

In the given situation, the beginning casing is demonstrated by 6 back to back ones followed by 2 zeroes.

the beginning casings are normally known as the flags.which are utilized for showing the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the receiver.

In this way here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).

Answer:

1.024x10^-5

Explanation:

To calculate the transmission delay bytes for the token,

we have the token to be = 64bytes and 10mbps rate.

The transmission delay = 64bytes/10mbps

= 51.2 microseconds

A microsecond is a millionth of a second.

= 5.12 x 10^-5

The question says the average number of stations that the token will pass through is 20. Remember this value is gotten from 40/2

20 x 5.12 x 10^-5

= 0.001024

= 1.024x10^-5

Therefore on an idle network with 40 stations, the average wait is

= 1.024x10^-5

Answer:

Here is the function same_person that takes two instances of Person as arguments i.e. p1 and p2 and returns True if they are the same Person, False otherwise.

def same_person(p1, p2):  #definition of function same_person that takes two parameters p1 and p2

   if p1.GTID==p2.GTID:  # if the two instances of Person have same GTID

       return True  #returns true if above condition evaluates to true

   else:  #if the two instances of Person do not have same GTID

       return False #returns false when two persons have different GTID

Explanation:

person1 = Person("David Joyner", 30, 901234567)  #first instance of Person

person2 = Person("D. Joyner", 29, 901234567)  #second instance of Person

person3 = Person("David Joyner", 30, 903987654)  #third instance of Person

print(same_person(person1, person2))  #calls same_person method by passing person1 and person2 instance of Person to check if they are same

print(same_person(person1, person3)) #calls same_person method by passing person1 and person3 instance of Person to check if they are same

The function works as follows:

For function call print(same_person(person1, person2))

The GTID of person1 is 901234567 and that of person2 is 901234567

If condition if p1.GTID==p2.GTID in the function same_person checks if the GTID of person1 is equal to the GTID of person2. This condition evaluates to true because GTID of person1 = 901234567 and GTID of person2 = 901234567

So the output is:

True

For function call print(same_person(person1, person3))

The GTID of person1 is 901234567 and that of person3 is 903987654

If condition if p1.GTID==p2.GTID in the function same_person checks if the GTID of person1 is equal to the GTID of person3. This condition evaluates to false because GTID of person1 = 901234567 and GTID of person2 = 903987654 and they are not equal

So the output is:

False
