The majority of sectors contain sensitive data that, if revealed, could cause serious harm to a company's reputation, loss of sales, legal expenses, punitive damage costs, and non-compliance fines. Protecting sensitive data on USB drives is a top priority, according to almost 80% of poll participants. By failing to appropriately monitor these devices and the data that is written to them, businesses expose themselves to data breaches and leaks.Although businesses are aware of the value of USB drives for productivity and efficiency, only 50% of them are needed to get authorization before using an external USB drive. The fact that these and other inadequate security measures will eventually make firms exposed to data compromise and assault may not come as a surprise.

Answer:

You access the object's attributes using the dot operator with object. Class variable would be accessed using class name as follows −

emp1.displayEmployee()

emp2.displayEmployee()

print "Total Employee %d" % Employee.empCount

Now, putting all the concepts together −

Live Demo

#!/usr/bin/python

class Employee:

  'Common base class for all employees'

  empCount = 0

  def __init__(self, name, salary):

     self.name = name

     self.salary = salary

     Employee.empCount += 1

  def displayCount(self):

    print "Total Employee %d" % Employee.empCount

  def displayEmployee(self):

     print "Name : ", self.name,  ", Salary: ", self.salary

"This would create first object of Employee class"

emp1 = Employee("Zara", 2000)

"This would create second object of Employee class"

emp2 = Employee("Manni", 5000)

emp1.displayEmployee()

emp2.displayEmployee()

print "Total Employee %d" % Employee.empCount

When the above code is executed, it produces the following result −

Name :  Zara ,Salary:  2000

Name :  Manni ,Salary:  5000

Total Employee 2

You can add, remove, or modify attributes of classes and objects at any time −

emp1.age = 7  # Add an 'age' attribute.

emp1.age = 8  # Modify 'age' attribute.

del emp1.age  # Delete 'age' attribute.

Instead of using the normal statements to access attributes, you can use the following functions −

The getattr(obj, name[, default]) − to access the attribute of object.

The hasattr(obj,name) − to check if an attribute exists or not.

The setattr(obj,name,value) − to set an attribute. If attribute does not exist, then it would be created.

The delattr(obj, name) − to delete an attribute.

hasattr(emp1, 'age')    # Returns true if 'age' attribute exists

getattr(emp1, 'age')    # Returns value of 'age' attribute

setattr(emp1, 'age', 8) # Set attribute 'age' at 8

delattr(empl, 'age')    # Delete attribute 'age'

Built-In Class Attributes

Every Python class keeps following built-in attributes and they can be accessed using dot operator like any other attribute −

__dict__ − Dictionary containing the class's namespace.

__doc__ − Class documentation string or none, if undefined.

__name__ − Class name.

__module__ − Module name in which the class is defined. This attribute is "__main__" in interactive mode.

__bases__ − A possibly empty tuple containing the base classes, in the order of their occurrence in the base class list.

For the above class let us try to access all these attributes

class Employee:

  'Common base class for all employees'

  empCount = 0

  def __init__(self, name, salary):

     self.name = name

     self.salary = salary

     Employee.empCount += 1

  def displayCount(self):

    print "Total Employee %d" % Employee.empCount

  def displayEmployee(self):

     print "Name : ", self.name,  ", Salary: ", self.salary

print "Employee.__doc__:", Employee.__doc__

print "Employee.__name__:", Employee.__name__

print "Employee.__module__:", Employee.__module__

print "Employee.__bases__:", Employee.__bases__

print "Employee.__dict__:", Employee.__dict__

When the above code is executed, it produces the following result −

Employee.__doc__: Common base class for all employees

Employee.__name__: Employee

Employee.__module__: __main__

Employee.__bases__: ()

Employee.__dict__: {'__module__': '__main__', 'displayCount':

<function displayCount at 0xb7c84994>, 'empCount': 2,

'displayEmployee': <function displayEmployee at 0xb7c8441c>,

'__doc__': 'Common base class for all employees',

'__init__': <function __init__ at 0xb7c846bc>}

For a price, some auctions give a 30-day warranty on the engine, frame, and body. When you are at an auction, you should always have the adage "Buyer Beware" in mind. The car cannot be taken to a technician for an inspection, and it is typically sold "as is" with no warranties. Unless the title turns proved to be counterfeit, all sales are final. Verbal pledges are meaningless; pay no attention to them. Because they always win, you don't want to be in a scenario where it is your word against theirs. At an auction, always assume the worse.

Answer:

A

Explanation:

a) To find the dot product of the vectors u and v, we can use the Dot function in Mathematica. The dot product is calculated as follows:

u.v = Dot[u, v]

b) To find the angle between vectors u and v, we can use the ArcCos function in Mathematica. The angle is calculated as follows:

angle = ArcCos[(u.v)/(Norm[u]*Norm[v])]

c) We can graph both vectors u and v on the same system using the ListVectorPlot3D function in Mathematica. This will display the vectors in a 3D coordinate system.

ListVectorPlot3D[{u, v}]

d) To graph vectors u, v, and u * v on the same set of axes with different colors, we can use the Graphics3D function in Mathematica. We can assign a different color to u * v using the Directive function.

Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],

 Directive[Red], Arrow[{{0, 0, 0}, u*v}]}]

e) To rotate the graph from part d and show two different views of the cross product, we can use the ViewPoint option in the Graphics3D function. By specifying different viewpoints, we can obtain different perspectives of the graph.

Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],

 Directive[Red], Arrow[{{0, 0, 0}, u*v}]},

ViewPoint -> {1, -1, 1}]

Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],

 Directive[Red], Arrow[{{0, 0, 0}, u*v}]},

ViewPoint -> {1, 1, 1}]

f) To find the normal vector to vector u, we can use the Cross function in Mathematica. The normal vector is calculated as follows:

normal = Cross[u]

The function Cross[u] computes the cross product of u with the standard basis vectors. The resulting vector represents the direction perpendicular to the plane spanned by u.

Some examples of access control systems are: Card-based access control systems, Biometric access control systems, Keypad access control systems, Proximity access control systems

Access control systems are used to limit or control access to certain areas or resources by determining who or what is authorized to enter or exit. In modern-day society, access control systems are widely used in both commercial and residential settings to enhance security and safety. Some examples of access control systems are discussed below.

1. Card-based access control systems- These are the most common types of access control systems. In card-based systems, authorized personnel are issued an access card that contains a unique code or number. When the person swipes the card through a reader, the system checks if the card is valid and then unlocks the door.

2. Biometric access control systems- In this system, the user's unique physical characteristics are used to identify them, such as fingerprints, voice, face, or retina scans. Biometric systems are highly accurate and provide enhanced security.

3. Keypad access control systems- Keypad systems use a secret code entered through a keypad. The code can be changed frequently to prevent unauthorized access.

4. Proximity access control systems- Proximity systems use a small chip or key fob that emits a radio signal to a reader mounted near the door. When the signal is received, the door unlocks. These are just a few examples of access control systems. There are other systems like security guards, smart cards, RFID-based systems, and more.
