Answer:
This is the instance method inc_num_kids()
def inc_num_kids(self):
self.num_kids += 1
Explanation:
The first line is the definition of function inc_num_kids() which has a parameter self. self is basically an instance of class PersonInfo
self.num_kids += 1 this statement incremented the data member num_kids by 1. This means that the instance method inc_num_kids, using instance self, increments the value of num_kids data member by 1.
The complete program is as following:
class PersonInfo: #class name PersonInfo
def __init__(self): #constructor of the class
self.num_kids = 0 # data member num_kids
def inc_num_kids(self): # method inc_num_kids
self.num_kids += 1 #increments num_kids by 1
person1 = PersonInfo() #creates object person of class PersonInfo
print('Kids:', person1.num_kids) # prints num_kids value before increment
person1.inc_num_kids() #calls inc_num_kids method to increment num_kids
print('New baby, kids now:', person1.num_kids) #prints the value of num_kids after increment by inc_num_kids method
The person1 object first access the initial value of num_kids initialized by the constructor. So the first value of num_kids is 0. self.num_kids = 0 This statement assigns the value 0 to num_kids data member. Next the method inc_num_kids() using the object person1. Now when this method is called the value of data member num_kids is incremented to 1.
So previously the value was 0 which now increments by 1 and becomes 1. Last print statement displays this new value which is incremented by the inc_num_kids() method.
Hence the output is:
Kids: 0
New baby, kids now: 1
The program along with its output is attached.
Answer:
The recommendations for Jesse about creating an SCR help desk are, the user interface, sending of data request to servers, sending data files back to the server, receiving data files from the server, running an application programs locally to process data.
File server handles several jobs which includes, sending data files to client, storing of data files, and generating traffic on the internet.
The client/server tiers allows user interface on the client and data can be stored on the server. it's elements includes the following: output, input, processes, performance, control and security
Explanation:
Given that:
(1)The recommendations is stated as follows:
A file sharing architecture is recommended where the clients can handle the following:
- The user interface
- Sends data request to servers
- Sends data files back to the server
- Receives data files from the server
- Runs application programs locally to process data
The file server handles the following tasks or jobs which is stated below:
- Receives data request from clients
- Sends data files to client
- Stores data files
- Manage multi-user access
- Generate LAN traffic
The Client design:
- Lower network traffic
- Faster performance
- Lower initial cost
- Lower maintenance cost
The disadvantage of this, is that it is more difficult to design
