Explain why, from a programmer's point of view, deep access is better than shallow access, not just in terms of speed.

Don't just argue performance—make a programmer's case for deep access over shallow access. Q 347

Compilers and Assemblers build object code files by translating each source file one at a time. As a result, running the object files requires linking them together first. However, it is theoretically feasible to bypass the linking stage and simply build the final executable file from the compilers. What would be the drawbacks of the second option?

Is the usage of user-level threads superior than kernel-level threads? What is the difference between user-level threads and kernel-level threads? Is there ever a period when one kind is superior than another?

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  False

Compilers 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?

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?

What is the difference between a thread running in the user mode and one running in the kernel mode? Is there a favored species among the alternatives?
