Describe the ACID properties in database management. How do they ensure the reliability and consistency of transactions?

Write a program in C  that can convert a bit stream of a message into a frame by using Hamming coding. The bit stream is the input parameter of the program. For example, given an input parameter as 1001000, the correct output of the frame is 00110010000. Input bit stream will have 1 to 64 bits. Some self-testing examples are:Input 1001000; output 00110010000Input 1101001100110101; output 011110110011001110101Input 1010101; output 11110100101Input 11111111; output 111011101111   Write a program in C  that can convert a bit stream of a message into a frame by using CRC. The bit stream is the first input parameter of the program, which will have 8 to 128 bits. The generator function is the second input parameter of the program, which will have 4 to 16 bits. For example, if the generator function is x^4 + x + 1, the second input will be 10011. The output should be the transmitted bit stream with its CRC checksum bits; see example in Figure 3-9 in the textbook. Some self-testing examples…
