Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:

Consider a system where free space is kept in a free-space list. a. Suppose that the pointer to the free-space list is lost. Can the system reconstruct the free-space list? Explain your answer. b. Consider a file system similar to the one used by UNIX with indexed allocation. How many disk 1/0 operations might be required to read the contents of a small local file at /a/b/c? Assume that none of the disk blocks is currently being cached. c. Suggest a scheme to ensure that the pointer is never lost as a result of memory failure.
For the following buffer pool, using the LRU replacement heuristic, show the disk block ID of the buffer pool as each disk block is called using the table below. Assume that the buffer pool is initially empty.
To improve performance when reading files, "block read ahead" can be performed. What is this? A. The operating system determines, when reading block K, if the file is being read sequentially. If it is, the file system will retrieve block K, and initiate the request for block K+1 in the file. B. The operating system determines, when writing block K, if the file is being written sequentially. If it is, the file system will retrieve block K, and initiate the request for block K+1 in the file. C. The operating system determines when reading block K if that block was accessed via a seek. If it is, the file system will retrieve block K, and initiate the request for the next block in the file that is needed by the process. D. All of the above
Problem 0. Suppose a file contains 100 bytes of data. A program successfully opens it for both reading and writing (i.e., passing the mode O_READWR to open()), and gets back a file descriptor number fd. a. The program, which has a 40-byte buffer, issues a call to read() for 40 bytes. It processes that data, and then repeats the call. Both calls return the exact amount requested. Then it issues a third read, again requesting 40 bytes. What value will it return? (Assume no other program has the file open.) b. Next the program calls write (fd, buffer, 40), and the call returns 40. Then it issues another read() call for 40 bytes. What value does that call return? c. Suppose the programmer needs to read back the 40 bytes just written. First it must use 1seek() to reposition the file pointer. What parameters should it invoke 1seek () with so that the next read call will return the 40 bytes just written?
Assuming 4K clustering for a 500-byte file, what is the size (in bytes) of the File Slack? O 12 bytes O 1536 bytes O 3584 bytes O 4096 bytes
2. a) Your colleague has invented a new scheduling algorithm using the multilevel queue approach. This list of processes showing CPU burst times is below. There are three queues used in the application. The processes all start on the first queue and receive upto 10ms of burst time. Once the process has received the 10ms on the first queue, if the process still requires burst time it is passed to the second queue where it receives upto 20ms. Once the process has received the 20ms on the second queue, if the process still requires burst time it is passed to the third queue where it receives CPU time until it is completed. The operating system will only start allocating CPU time to processes on the second queue when queue 1 is empty. The operating system will only start allocating CPU time to processes on the third queue when queue 2 is empty. Process Number P1 P2 P3 P4 Burst time (ms) 21 8 35 50 i) Does this algorithm give higher priority to any queue over the others and any processes…

2. Exploring envp:a. Modify showEnvp.c so it reports envp addresses in the same style as showArgs2 displays argv addresses. Save a copy of the output in a file – you’ll need to refer to it in part b. Provide a program listing, a status statement and 6-8 lines of output, but not all the output. (2)b. Inside your program use putenv to define one environment variable and setenv to redefine another. Do these values appear in the array envp or __environ or both? (2)c. Based on the program output sketch a data structure diagram for envp. You only need to include the first 3 environment variable values (2) Hand in a commented listing of your program, proof of testing and a status report.
