A user on a UNIX host wants to transfer a 4000-byte text file to a Microsoft Windows host. To do this, he transfers the file by means of TFTP, using the netascii transfer mode. Even though the transfer was reported as being performed successfully, the Windows host reports the resulting file size is 4050 bytes, rather than the original 4000 bytes. Does this difference in the file size imply an error in the data transfer? Why or why not?

Consider a system that allocates pages of different sizes to its processes. What are the advantages of such a paging scheme? What modifications to the virtual memory system are provide this functionality?

For this assignment, you will create a parallel fixed-length code decompressor using the tools we learned in class to create multiple processes and threads. Computers represent a character as a sequence of 8 bits, which means you can represent up to 256 symbols per character. However, depending on the source, it is common to have messages/files using an alphabet with a size of fewer than 256 symbols. The simplest way to achieve compression is to use a fixed-length code generator. The idea behind this type of code generator is to assign a fixed-length bit sequence to each alphabet symbol. Given an alphabet (where each symbol is represented by a character and a decimal value with the code of the symbol), you need to implement a fixed-length code decompressor based on the following steps:   ◦Read the contents of the input file using input redirection (STDIN). The format of the input file is as follow:   - An integer value representing the number of symbols in the alphabet - n lines (where…
