Answer:

Platform as a Service (PaaS).

Explanation:

In this scenario, an app developer is shopping for a cloud service that will allow him to build code, store information in a database and serve his application from a single place. The type of cloud service he is looking for is a platform as a service (PaaS).

In Computer science, Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.

The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.

Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).

Hence, the advantage of the Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.

These are the different types of Platform as a Service;

1. Private PaaS.

2. Public PaaS.

3. Hybrid PaaS.

4. Mobile PaaS.

5. Communications PaaS.

6. Open PaaS.

The software developers can choose any of the aforementioned types of PaaS that is suitable, effective and efficient for their applications development. Some examples of PaaS providers are Google, Microsoft, IBM, Oracle etc.

Answer:

Modify your program by replacing

for x in country:

       country_gold.append(gold[x])

       country_gold.append("Did not get gold")

with

for x in country:

       try:

               country_gold.append(gold[x])

       except:

               country_gold.append("Did not get gold")

Explanation:

The addition of try/except clause in the program is to let the program manage error;

In this case, the program checks for a country in the list country; This is implemented using the following line

for x in country:

If the country exists, the statement in the try block is executed

try:

 country_gold.append(gold[x])  ->This appends the country name to the country_gold list

Otherwise, the statement in the except clause is executed

except:

 country_gold.append("Did not get gold")  -> This appends "Did not get gold" to the country_gold list

To confirm what you've done, you may add the following line of code at the end of the program: print(country_gold)

Answer:

Here is the python code:

StartingSal = int(input("Enter the starting salary: "))

AnnualIncrease = (int(input("Enter the annual % increase: ")) / 100)

Years = int(input("Enter the number of years: "))

for count in range(1,Years+1):  

  print("Year ", count, " Salary: ", StartingSal*((1+AnnualIncrease)**(count-1)))

Explanation:

This program prompts the user to enter starting salary, percentage increase in salary per year and number of years.

The for loop has range function which is used to specify how many times the salaries are going to be calculated for the number of years entered. It starts from 1 and ends after Years+1 means one value more than the year to display 10 too when user inputs 10 days.

The year and corresponding salary is displayed in output. At every iteration the starting salary is multiplied by annual percentage increase input by user. Here count is used to count the number of salaries per year, count-1 means it will start from 30000.

Answer:

1. Blockchain Technology: Blockchain is a distributed ledger technology that lets data to be stored globally on its servers and it is based on a P2P topology which makes it difficult for someone to tamper with the network.

It can be used as a cryptocurrency wallet that supports BitCoin, Ethereum, etc.

An advantage of it is that it is distributed among several users and stable.

A disadvantage for a developing country like Ghana is that once a blockchain is sent, it cannot go back which brings up the question of security.

2.Artificial Intelligence: This technology is simply the simulation of human intelligence in machines. AI can be used for problem-solving and learning. An advantage of AI is that it reduces human error and is fast in solving problems. A disadvantage of AI is that its expensive to maintain and also it does not improve with experience.

3. Global Positioning System: GPS is a satellite-based positioning system that is used to pinpoint and track location. It has the advantage of being available worldwide and information is provided to users in real-time. One disadvantage of the GPS for a developing country like Ghana is that electromagnetic interference can affect the accuracy of the GPS.

4. 5G Network: This is the 5th generation of mobile internet connectivity that gives super fast download and upload speeds when compared to its predecessors 4G, 3G, 2G, and Edge networks.

One major disadvantage of 5G for a developing country like Ghana is that it is expensive and quite unknown and its security and privacy issues are yet to be resolved.

5. Lasers: This isn't a new technology as it has been in use for some time already but its importance cannot possibly be over-emphasized. LASER is an acronym that means Light Amplification by the Stimulated Emission of Radiation.

It is precise and accurate in cutting when compared to thermal and other conventional cutting methods. It is being used in surgeries that require the highest levels of accuracy with great success.

A disadvantage of Laser technology is that it is expensive to use and maintain.

Answer:

The program written in python is as follows;

import string

def easyCrypto(inputstring):

      for i in range(len(inputstring)):

             try:

                    ind = string.ascii_lowercase.index(inputstring[i])

                    pos = ind+1

                    if pos%2 == 0:

                           print(string.ascii_lowercase[ind-1],end="")

                    else:

                           print(string.ascii_lowercase[ind+1],end="")

             except:

                    ind = string.ascii_uppercase.index(inputstring[i])

                    pos = ind+1

                    if pos%2 == 0:

                           print(string.ascii_uppercase[ind-1],end="")

                    else:

                           print(string.ascii_uppercase[ind+1],end="")

anystring = input("Enter a string: ")

easyCrypto(anystring)

Explanation:

The first line imports the string module into the program

import string

The functipn easyCrypto() starts here

def easyCrypto(inputstring):

This line iterates through each character in the input string

      for i in range(len(inputstring)):

The try except handles the error in the program

             try:

This line gets the index of the current character (lower case)

                    ind = string.ascii_lowercase.index(inputstring[i])

This line adds 1 to the index

                    pos = ind+1

This line checks if the character is at even position

                    if pos%2 == 0:

If yes, it returns the alphabet before it

                           print(string.ascii_lowercase[ind-1],end="")

                    else:

It returns the alphabet after it, if otherwise

                           print(string.ascii_lowercase[ind+1],end="")

The except block does the same thing as the try block, but it handles uppercase letters

             except:

                    ind = string.ascii_uppercase.index(inputstring[i])

                    pos = ind+1

                    if pos%2 == 0:

                           print(string.ascii_uppercase[ind-1],end="")

                    else:

                           print(string.ascii_uppercase[ind+1],end="")

The main starts here

This line prompts user for input

anystring = input("Enter a string: ")

This line calls the easyCrypto() function

easyCrypto(anystring)

Explanation:

1. Industry 4.0 -automation revolution is a term first used in Germany in 2011 to describe the fourth generation of the industrial revolution. It is the incorporation of digitalized procedures that use smart technology that can work in real-time to industrial production. This means that the machines used in production can independently interact between themselves to accomplish tasks that would otherwise have needed human involvement.

2. My opinion regarding this industrial revolution is that it is a welcome development for businesses because it will help them execute projects at faster rates and limit some working expenses.

3. Unskilled and Semi-skilled workers will be badly affected by this revolution because tasks ordinarily performed by them would be mostly taken over by these machines. This means that companies would most likely lay off these workers whose jobs would now be performed by machines. Job regulation agencies would do well to seek ways to intervene for this group of workers. They may also have to improve their skills if they want to remain relevant to their jobs.

The revolution, however, would be favorable for high-skilled workers because they would be needed to perform jobs such as the maintenance and programming of these machines.

Explanation:

Alcatel-Lucent was founded in 1919, it was a French global telecommunications equipment manufacturing company with its headquarter in Paris, France. Alcatel-Lucent provide services such as telecommunications and hybrid networking solutions deployed both in the cloud and on properties.

Alcatel-Lucent’s High Leverage Network (HLN) increases bandwidth and network capabilities while reducing the negative impact on the environment. This high leverage network can handle large amounts of traffic more efficiently because the networks are intelligent and send packets at the highest speed and most efficiently. HLN are intelligent such that it delivers increased bandwidth using fewer devices and energy.

Generally, when the High Leverage Network (HLN) is successfully implemented, it helps telecommunications companies to improve their maintenance costs, operational efficiency, enhance network performance and capacity to meet the bandwidth demands of their end users.

Answer:

I am writing a Python program.

def phonebook(names, numbers):  #method phonebook that takes two parameters i.e a list of names and a list of phone numbers

   dict={}  #creates a dictionary

   for x in range(len(names)):  # loop through the names

       dict[names[x]]=numbers[x]  #maps each name to its phone number

   return dict #return dictionary in key:value form i.e. name:number

#in order to check the working of this function, provide the names and numbers list and call the function as following:

names = ['Jackie', 'Joshua', 'Marguerite']

numbers = ['404-555-1234', '678-555-5678', '770-555-9012']

print(phonebook(names, numbers))

Explanation:

The program has a function phonebook() that takes two parameters, name which is a list of names and numbers that is a list of phone numbers.

It then creates a dictionary. An empty dictionary is created using curly brackets. A dictionary A dictionary is used here to maps a names (keys) phone numbers (values) in order to create an unordered list of names and corresponding numbers.

for x in range(len(names)):  

The above statement has a for loop and two methods i.e. range() and len()

len method is used to return the length of the names and range method returns sequence of numbers just to iterate as an index and this loops keeps iterating until x exceeds the length of names.

dict[names[x]]=numbers[x]

The above statement maps each name to its phone number by mapping the first name with the first  umber, the second name with the second number and so on. This mapping is done using x which acts like an index here to map first name to first number and so on. For example dict[names[1]]=numbers[1]  will map the name (element) at 1st index of the list to the number (element) at 1st index.

return dict retursn the dictionary and the format of dictionary is key:value where key is the name and value is the corresponding number.

The screenshot of the program and its output is attached.

The available options are:

Answer:

C.  localhost/htdocs/Carla/hello.php  

Explanation:

A path in computer programming can be defined as the name of a file or directory, which specifies a unique location in a file system.

Therefore, to get the correct path to enter to view this page in a browser, one needs to follow the directory tree hierarchy, which is expressed in a string of characters in which path components, separated by a delimiting character, represent each directory.

Hence, correct path to enter to view this page in a browser is "localhost/htdocs/Carla/hello.php"

A. These describe the authority level of workers, fair payment practices, communication channels, and the like.  

Explanation:

As seen in the question above, you have been asked to write the project management plan and know that you need to consider elements such as policies, rules, systems, relationships and standards in the organization. These elements are part of EEF's entry into this process, in addition they are fundamental and indispensable for the description not only of the organizational governance structure, but also describe the management elements that will be adopted and used.

However, there is no way to use them to describe the level of authority of workers, fair payment practices, communication channels and the like, as this is not the function of this.

Answer:

There is a problem in the given code in the following statement:

Problem:

punctuation = r"[.?!,;:-']"

This produces the following error:

Error:

bad character range

Fix:

The hyphen - should be placed at the start or end of punctuation characters. Here the role of hyphen is to determine the range of characters. Another way is to escape the hyphen - using using backslash \ symbol.

So the above statement becomes:

punctuation = r"[-.?!,;:']"  

You can also do this:

punctuation = r"[.?!,;:'-]"  

You can also change this statement as:

punctuation = r"[.?!,;:\-']"

Explanation:

The complete program is as follows. I have added a print statement print('string1:',string1,'\nstring2:',string2) that prints the string1 and string2 followed by return string1 == string2  which either returns true or false. However you can omit this print('string1:',string1,'\nstring2:',string2) statement and the output will just display either true or false

import re  #to use regular expressions

def compare_strings(string1, string2):  #function compare_strings that takes two strings as argument and compares them

   string1 = string1.lower().strip()  # converts the string1 characters to lowercase using lower() method and removes trailing blanks

   string2 = string2.lower().strip()  # converts the string1 characters to lowercase using lower() method and removes trailing blanks

   punctuation = r"[-.?!,;:']"  #regular expression for punctuation characters

   string1 = re.sub(punctuation, r"", string1)  # specifies RE pattern i.e. punctuation in the 1st argument, new string r in 2nd argument, and a string to be handle i.e. string1 in the 3rd argument

   string2 = re.sub(punctuation, r"", string2)  # same as above statement but works on string2 as 3rd argument

   print('string1:',string1,'\nstring2:',string2)  #prints both the strings separated with a new line

   return string1 == string2  # compares strings and returns true if they matched else false

#function calls to test the working of the above function compare_strings

print(compare_strings("Have a Great Day!","Have a great day?")) # True

print(compare_strings("It's raining again.","its raining, again")) # True

print(compare_strings("Learn to count: 1, 2, 3.","Learn to count: one, two, three.")) # False

print(compare_strings("They found some body.","They found somebody.")) # False
