Question
Files containing object code are generated by compilers and assemblers from source files. The object files need to be linked together before they can be executed. In theory, compilers might produce executables without connecting the individual files together. What problems does this second method have?

Both nested routines often use a similar shared stack for arguments as well as the remainder of the background of each calling method. (a) Describe the flaws that this vulnerability exposes.

It is possible to run object files by linking them together. It is not necessary to link the executables that compilers generate. Where exactly do its flaws lie?arrow_forward
- Multi-tasking can not be achieved with a single processor machine. True False 2. Async/Await is best for network bound operations while multi-threading and parallel programming is best for CPU-bound operations. True False 3. The following is a characteristic of an async method:The name of an async method, by convention, ends with an "Async" suffix. True False 4. Using asynchronous code for network bound operations can speed up the time needed to contact the server and get the data back. True False 5. Asynchronous programming has been there for a long time but has tremendously been improved by the simplified approach of async programming in C# 5 through the introduction of: The Task class True Falsearrow_forwardCompilers and assemblers are responsible for turning source files into files containing object code. First, the object files need to be linked together before they can be executed. Compilers have the potential to produce final executable files even in the absence of linking. What are some of the problems associated with using the second approach?arrow_forwardMatch the correct stage of compilation on the left to the description of what occurs at the step shown on the right. Compilation Assembly Preprocessing Linking 1. 2. 3. 4. 5. 6. the CPU executes the resulting machine code file after linking library functions entire contents of certain files are copy/pasted into the source file and some substitutions are made within the source file assembly language is translated to architecture-specific machine code machine code is arranged into an executable with functions external to the program being brought in as well high-level language is translated to architecture-specific assembly language high-level language is translated to architecture-specific machine codearrow_forward
- Compilers and assemblers generate object code from source files. Linking object files allows them to execute. Compilers can produce executables without linking. The latter approach's drawbacks?arrow_forwardDuring the first pass of an assembler: Group of answer choices external code is merged with the object code. instructions are only partially assembled. the symbol table is only partially completed. addresses from the symbol table are placed in object code.arrow_forwardHow does object serialization cater to backward compatibility in software applications?arrow_forward
