Can you explain the function of the "access rights byte" in protected mode?
Step by step
Solved in 2 steps
- Use select to avoid deadlock goroutines and write go codeMutual Exclusion: Select all of the following statements that are true. The Peterson Algorithm does not rely on the mechanism of busy waiting. The Peterson Algorithm is a purely software-based solution to the mutual exclusion problem. The only way to guarantee the atomicity of operations is to disable interrupts. Mutex Locks are an API offered by operating systems to protect critical sections. In order to enter a critical section protected by Mutex Locks, the release() operation must be executed first. The test_and_set instruction is atomic.Did I correctly do this function? Did I correctly do the precondition and postcondition? //Precondition: flag_position is a non-negative integer and hBit_flags is a handle to a valid Bit_flags object.//Postcondition: returns the value of the flag at index flag_position if it is in bounds or -1 otherwise.int bit_flags_check_flag(BIT_FLAGS hBit_flags, int flag_position){Bit_flags* pBit_flags = (Bit_flags*)hBit_flags;int i = flag_position / 32;flag_position %= 32;return ((1 << flag_position) & (pBit_flags->data[i])) != 0;if (flag_position <= pBit_flags->capacity) { return *pBit_flags->data;}else{ return -1;}}

- This is concerning files in c/c++ If I wanted to do the equivalent of a command-line rm followed by touch with one C function call, what would that be? Assume that pathToCleanse holds the path to that fileA program evaluates binary arithmetic expressions that are read from an input file. All of the operands are integers, and the only operators are +, -, *, and 7. In writing the program, the programmer forgot to include a test that checks whether the right-hand operand in a division expression equals zero. When will this oversight be detected by the computer? (A) At compile time (B) While editing the program (C) As soon as the data from the input file is read (D) During evaluation of the expressions (E) When at least one incorrect value for the expressions is outputGoal:Experimenting with AES-128 symmetric key cipher. Note:Using Python programming language that provided libraries for AES. Description:PART 1: write a program that uses AES-128 to decrypt a message. The program should be named "decrypt", and should deal with three files that contain the encrypted text as a stream of bytes, the 128-bit key for decryption stored as a stream of bytes, and the outcome of the decryption, respectively.- To test this program, here's an example of an encrypted message (ciphertext.dat) and its 128-bit secret key (key.dat). PART 2: you will try to use "brute force" to decrypt an encrypted message, where you only have the first 96-bits of the 128-bit secret key (last 4 bytes of the secret key are missing!) The program should be called "findk", and should deal with two files that contain the encrypted text as a stream of bytes and the first 96-bits of the key, respectively. The program should print out on standard output the missing 4 bytes of the key in…
- Write a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits.If the file exists, it also gets the name of two more files from the user, say destination1 and destination2. These files don’t need to exist as they are files that need to be written to. If the files cannot be opened for writing, a proper error will be generated. The program then reads the source file line by line. It will copy every line that has a digit in it to destination 2 and lines that have no digit in them to destination 1. Feel free to use ctype’s isdigit() function to identify digit characters. Example: If source file is:Hi My name is VeriaHello My name is John. How can I help you?I have a problem with my giga bit internet. The speed should be around 1000 but it’s just 200 Sure! I can help with that. Can I have your number in case we get disconnected? Sure! My number’s 647-123-1234 First file (destination 1) should be Hi My name is Veria Hello…Which setting of the Direction flag results in the reverse direction of the index registers across memory while executing string primitives?Given a code snippet in C++, write the equivalent codes in MIPS. Note: You may use any register that is deemed appropriate to assign the variables to your register Submission instructions: 1. Save each code snippet in a QtSPIM readable file (save as *.asm). Name your file according the the snippet name. E.g.: for snippet 1, save as Snippet1.asm. 2. Create a word document and answer these questions: a. Snippet 2: What is the value of s? Snippet 2: int i=3, j=5, k=9, s; if (j < k) { } s =j+ k + 1; } else { s = j - k + i;
