5. what is the starvation problem in cpu scheduling? list 2 which scheduling algorithms which have this problem. what is the solution? explain it.

Answers

Answer 1

Indefinite blocking or starvation is a phenomenon associated with Priority scheduling algorithms in which a process ready for the CPU (resources) could perhaps wait indefinitely due to low priority.

Starvation is most common in algorithm like Priority Scheduling or Shortest Job First Scheduling.

Solutions to Handle Starvation:

The following are several solutions that could be implemented in a system for dealing with starvation:

For resource allocation, an independent manager can be employed. This resource manager attempts to ignore starvation by distributing resources fairly.

Random process selection for allocation of resources or processor allocation must be avoided because it promotes starvation.

The resource allocation priority scheme must include concepts including such Aging, with the priority of a process increases the longer it waits, avoiding Starvation.

I. Write a RightTriangle class in Python that meets these specifications:
has an __init__ method that
takes either two parameters(the two non-hypotenuse sides) or three (including the hypotenuse). If only two parameters are sent, the hypotenuse is calculated using the Pythagorean theorem. Either way, set instance variables for the two sides and the hypotenuse, with names that make it clear which is which. Remember to import math.
raises exceptions if any of the parameters are negative or can't be cast to float, or if three parameters are supplied and they are not a valid Pythagorean triple (ie, if it is not true that the a2 + b2 = c2). Test this using the technique involving absolute value, not with the == operator. The exceptions should have informative messages (like "Error: both sides and the hypotenuse must be nonnegative"). The exceptions will be handled with in client code (the code that tries to create RightTriangles).
has an __eq__ method that
returns false if the hypotenuse of the other RightTriangle is not very close to equal to the hypotenuse of this RightTriangle (use the technique involving absolute value)
else, returns true if the two sides of the other triangle are very close to the two sides of this triangle, including if the other triangle's side a is very close to this triangle's side b and vice-versa
else, returns false
has a __str__ method that returns a string like this one:
Right Triangle with side a = 3.0, side b = 4.0, and hypotenuse = 5.0
II. Write client code (does not need to be in a class or even a function) that does the following:
first, asks the user for two nonnegative numeric values for the sides, prints the Exception messages raised by the init method if the input is invalid, and keeps asking until valid input is received and a RightTriangle is returned, keeping a reference to the triangle
then, does the same with three values, asking repeatedly until valid values are received for the sides and hypotenuse of a valid right triangle, keeping a reference to the triangle
shows whether the first triangle is equal to itself, then whether the first triangle is equal to the second one.
Paste your code an the output form a test run in the window.

The hypotenuse is always opposite the right angle and it is always the longest side of the triangle.

How do you print a right angled triangle pattern in Python?We need to print a right-angled triangle pattern in this Python problem involving the right triangle. When we look at the triangle, the angles at the top and left side should be 90 degrees. Enter the user's desired row count. Place it in a variable, such as N. Run a loop structure for(i=1; i=N; i++) to iterate through rows using an outer loop from 1 to N. Use the loop structure for(j=1; j=i; j++) to iterate through the columns using an inner loop from 1 to i. As a result, a=1, b=2, and c=3 if this were a Pythagorean triple. of which is false.

Solving right triangles

Pythagorean theorem: a2 + b2 = c2. Sines: sin A = a/c, sin B = b/c. Cosines: cos A = b/c, cos B = a/c.

n = int(input("Enter the number of rows: "))

m = (2 * n) – 2.

An item, like a file, that is shared by several processes is relevant to the readers-writers dilemma.

What is reader/writer ?A readers-writer is a synchronisation primitive that addresses one of the readers-writers difficulties in computer science. For read-only tasks, a RW lock permits concurrent access; write actions demand exclusive access.Some RW locks allow the lock to be degraded from write mode to read mode as well as upgraded atomically from read mode to write mode. When two threads holding reader locks try to upgrade to writer locks at the same time, a stalemate results that can only be broken by one of the threads releasing its reader lock. This makes it difficult to employ upgradeable RW locks safely.

About MDI

Multiple Document Interface or MDI is a typical user interface in which each document in an application is displayed in a separate child window within the client area of the application's main window.

MDI applications have three types namely Frame window window, MDI client window and a number of child window windows.

The frame is like the main window of the application which usually has a sizing border, title bar, window menu, minimize button and maximize button.The client window is a child of a window frame that serves as the background for the child windows.

An MDI application has three kinds of windows namely Frame window, an MDI client window and a number of child windows. The frame window is like the main window of the application which normally has a sizing border, a title bar, a window menu, a minimize button and a maximize button. The client window is a child of the frame window which serves as the background for the child windows.

adding a public key to .ssh/authorized keys is one way a hacker can retain access to the site after discovering a vulnerability

Answers

Adding a public key to .ssh/authorized keys is one way a hacker can retain access to the site after discovering a vulnerability. (True)

What is a public key?

With the use of two different keys—one public and one private—public key cryptography can encrypt or sign data. The public key is then made accessible to everyone.

The private key refers to the second key. Only the private key is capable of unlocking data that has been encrypted using the public key. Public key cryptography is also known as asymmetric cryptography because it employs two keys as opposed to one. The widespread use of TLS/SSL, which enables HTTPS, is particularly notable.

The term "key" refers to a piece of information used in cryptography to scramble data so that it appears random; frequently, this key is a large number or string of numbers and letters.

Judging from what is shown in these photographs, The decoration on only one work can be described as black on black.

What are photographs?

An image produced by light striking a photosensitive surface, typically photographic film or an electronic image sensor like a CCD or CMOS chip, is called a photograph (also known as a photo, image, or picture).

Nowadays, most pictures are taken with a smartphone/camera, which uses a lens to concentrate the scene's visible light wavelengths into a replica of what the human eye would see. Photography refers to both the method and the practice of producing such images.

The Greek words (phos), meaning "light," and (graphê), meaning "drawing, writing," together meaning "writing with light," are the basis for Sir John Herschel's 1839 invention of the word "photograph."

Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis.

What is python a code or script?A list called "current members" is made in the python program above, and some values are added to it. The three variables member id, count, and is a member are defined in the following line.Count assigns a value to both the member id variables. and assign a False value to the variable "is a member" iterating through the list using a for loop.During the loop, If the statement will determine if the element is present. Afterward, change count to 1 and the is a member variable's value to True.Another if statement that checks the value of the count variable is used. is a member should be set to False if the count value is 0. The is a member variable's most recent value is displayed using the print() function.

Python is an interpreted language. Python uses an interpreter to translate and run its code. Hence Python is a scripting language.

if member_id in current_members:

is_a_member = True

else:

is_a_member = False

Consider a complete program below (This is attached). In the python program we created and initialized a list of current members (Their ids).

Then we prompt user to enter his id.

The program returns "Your Id is found you belong" or "Your  id is not found"

Python Code:-

#creating a list  

current_members = [4, 6, 9]

#defining the variable

#assigning the value

member_id = 9

#defining variable count

count = 0

#defining the variable and setting initial value to true

is_a_member = False

#for loop is used to iterate over the list  

for x in current_members:

 #if statement will check whether the element is found

 if x == member_id:

#set the value to true if the value is matched  

   is_a_member = True

   #set the value to 1

    count = 1

#if count == 0

#set the value of is_a_member variable to false
