- . Explain the differences between stream socket and datagram socket with diagram. javaA compiled program can be supplied as an executable file. An executable file is a file that is ready to run. Since an executable file cannot be run, programmers prefer to supply executables rather than source code. What is this executable file and what differentiates it from the source code? In the Python programming language, the process of source code translation is different from that in C programming, explainTo run COBOL code on z/OS, we right-click and select “Submit Job” on what file?
