note (Please solve the questions in the language of operating systems)

[1] Briefly, what is the difference between:

1- Buffering & Spooling.

2- Synchronous & Asynchronous I/O.

3- CPU-bound & I/O-bound jobs.

4- Multiprogramming & Timesharing.

5- Logical & Physical addresses.

6- User & Monitor modes in Operating System.

[2] (i) Define Timesharing.

    (ii) In a one processor system, there is an interrupt clock which is set to a “time slice Q”, that is, every Q an interrupt occurs to stop the process. There is only one I/O device in the system    which is interrupted when the process needs an I/O. There are 3 processes A, B, C.

     Process A executes an I/O interrupt every T units of time.

     Process B executes an I/O interrupt every 2T units of time.

     Process C executes an I/O interrupt every 3T units of time.

(a) Which of the above processes will benefit the most and which is not when Q = T.

      Explain your answer

(b) Which of the above processes will benefit the most and which is not when Q = 2T.

What is the best value should Q takes for good performance ? explain your answer in full.

[3] (a) Define DMA (Direct Memory Access).

      (b) An input device can transmit 100 characters every 4 mils 10 , if the CPU needs 2 mics to service the

Apply and elaborate by providing real-life examples on the below mentioned basic concepts that are associated with risk management as per NIST (National Institute of Standards and Technology).   

a. TRUST AND TRUSTWORTHINESS

b. ORGANIZATIONAL CULTURE

Programming in C (not C++)

The high level goal of this project is to write a program called "wordfreak" that takes "some files" as input, counts how many times each word occurs across them all (considering all letters to be lower case), and writes those words and associated counts to an output file in alphabetical order.

We provide you some example book text files to test your program on. For example, if you ran

$ ./wordfreak aladdin.txt

Then the contents of the output file would be:

$ cat output.txt

a : 49

aback : 1

able : 1

...

required : 1

respectfully : 1

retraced : 1

...

that : 11

the : 126

their : 2

...

you : 20

young : 1

your : 7

The words from all the input files will be counted together. If a word appears 3 times in one input file and 4 times in another, it will be counted 7 times between the two.

Input

wordfreak needs to be able to read input from 3 sources: standard input, files given in argv, and a file given as the environment variable. It should read words from all these that are applicable (always standard in, sometimes the other 2).

A working implementation must be able to accept input entered directly into the terminal, with the end of such input signified by the EOF character (^D (control+d)):

$ ./wordfreak

I can write words here,

and end the file with control plus d

$ cat output.txt

and : 1

can : 1

control : 1

d : 1

end : 1

file : 1

here : 1

i : 1

plus : 1

the : 1

with : 1

words : 1

write : 1

However, it should alternately be able to accept a file piped in to standard input via bash’s operator pipe:

$ cat aladdin.txt | ./wordfreak

It should be noted that your program has no real way to tell which of these two situations is occuring, it just sees information written to standard input. However, by just treating standard input like a file, you will get both of these behaviours.

A working implementation must also accept files as command line arguments:

$ ./wordfreak aladdin.txt iliad.txt odyssey.txt

Finally, a working implementation must also accept an environment variable called WORD_FREAK set to a single file from the command line to be analyzed:

$ WORD_FREAK=aladdin.txt ./wordfreak

And of course, it should be able to do all of these at once

$ cat newton.txt | WORD_FREAK=aladdin.txt ./wordfreak iliad.txt odyssey.txt

Words

Words should be comprised of only alpha characters, and all alpha characters should be taken to be lower case.

For example "POT4TO???" would give the words "pot" and "to". And the word "isn’t" would be read as "isn" and "t". While this isn't necessarily intuitively correct, this is what your code is expected to do:

$ echo "Isn’t that a POT4TO???" | ./wordfreak

$ cat output.txt

a : 1

isn : 1

pot : 1

t : 1

that : 1

to : 1

You are required to store the words in a specific data structure. You should have a binary search tree for each letter 'a' to 'z' that stores the words starting with that letter (and their counts). This can be thought of as a hash function from strings to binary search trees, where the hashing function is just first_letter - 'a'. Note that these BSTs will not likely be balanced; that is fine.

Output

The words should be written to the file alphabetically (the BSTs make this fairly trivial). Each word will give a line of the form "[word][additional space] : [additional space][number]\n". The caveat is that all the colons need to line up. The words are left-aligned and the longest will have a single space between its end and the colon (note "respectfully" in the example below); the numbers are right-aligned and the longest will have a single space between the colon and its beginning (note 126 in the example below).

$ ./wordfreak aladdin.txt

$ cat output.txt

a : 49

...

respectfully : 1

...

the : 126

...

your : 7

The output file should be named output.txt. Note that when opening the file to write to, you will either need to create the file or remove all existing contents, so make use of open()'s O_CREAT and O_TRUNC. Moreover, you will want the file’s permissions to be set so that it can be read. open()’s third argument determines permissions of created files, something like 0644 will make it readable.

restricted to only using the following system calls: open(), close(), read(), write(), and lseek() for performing I/O. You are allowed to use other C library calls (e.g., malloc(), free()). However, all I/O is restricted to the Linux kernel’s direct API support for I/O. You are also allowed to use sprintf() to make formatting easier.

Our AD is Movie Theater.
Create an ER diagram with the following entities: Staff, Ticket, Movie, Session, Hall, Seat, Director, Actor, Distributor, and Roles. AND also identify the type of relations between the entities with notations and explain why you used it.

**Read the question carefully before you answer**

Question 1 (25pts):

Consider the string “data and program analytics”. Write a program to perform the following actions

• Find the index of the character ‘p’ in the given string
• Print the character which is present at index number seven
• Find the length of the String
• Split the string at every occurrence of a whitespace
• Replace the word “data” in the original string with “information” using a standard string manipulation function. Your output after the manipulation should be “information and program analytics”

Question 2 (15 pts):

List1 = [3, 4, 5, 20, 5]

• Find the index of the second 5
• Find the last element of this list

Question 3 (15 pts):

Set1 = {1, 2, 3, 4}, Set2={4, 5, 6}

• Print all elements that appear in both sets
• Print those elements that appear in either set
• Print all elements that appear in Set1 but not Set2

Question 4 (15 pts):

L = [('',), (), ('apple', 1), (), ("Paul", "Merage', 2020, "MSBA212"), ("d")]

Write a Python program to remove an empty tuple(s) from a list of tuples.

Expected outcome is:

[('',), ('apple', 1), ('Paul', 'Merage', 2020, 'MSBA212'), 'd']

Question 5 (15 pts):

• Reverse words in the string "one apple a day keeps the doctors away" and print the new string
• Sort the words in the string "one apple a day keeps the doctors away" alphabetically and then print the new string.

Question 6 (15 pts):

Two given lists [1,2,4,8,5,10] and [2,4,5,8,12,15], write a program to make a list whose elements are intersection of the above given lists.

Instructions

• Complete the lab using “for loop”.
• Do not write the code in multiple programs. All the 3 methods should be written in 1 program.

1. Write a java program calls the following methods:
   1. printStars(): Takes an int (n) as parameter and prints n stars (*) using for loop.
   2. Multiples(): Takes an int (n) as parameter and prints first 10 multiples n in a single line using for loop.
   3. hasAnEvenDigit: Takes an int (n) as parameter and returns whether n has at least one digit whose value is even. Return true if the number has at least one even digit else false if none of the digits are even. For example, the call hasAnEvenDigit(33267) should return true and hasAnEvenDigit(7591) should return false.

[Hint: n%10 returns the last digit and n/10 returns everything except the last digit]
