1. Assemblers and linkers work together in the process of creating executable programs. The assembler takes assembly language code and translates it into machine code. The linker then takes this machine code and combines it with other pieces of machine code (like libraries) to create an executable program.

2. Studying assembly language enhances your understanding of operating systems because it allows you to understand how software interacts with hardware at a low level. It gives you a better understanding of how the operating system manages resources and executes processes.

3. A one-to-many relationship when comparing a high-level language to machine language means that one line of high-level language code can translate into many lines of machine language code. This is because high-level languages are designed to be more readable and easier to write, while machine language is designed to be executed efficiently by the computer.

4. Portability in programming languages refers to the ability of a piece of code to be run on different types of systems without requiring modification. The more portable a language is, the more systems it can run on.

5. No, the assembly language for x86 processors is not the same as those for computer systems such as the Vax or Motorola 68x00. Each type of processor has its own specific assembly language.

6. An example of an embedded systems application could be the software running on a digital watch. This software is designed to run on the specific hardware of the watch and perform specific tasks like keeping time and setting alarms.

7. A device driver is a piece of software that allows the operating system to interact with a hardware device. It provides a standard interface for the OS to use when communicating with the device.

8. Type checking on pointer variables is generally stricter in high-level languages like C and C++. This is because these languages have built-in mechanisms to prevent errors that can occur when dealing with pointers.

9. Two types of applications that would be better suited to assembly language than a high-level language are those that require direct hardware manipulation and those that need to be extremely efficient, like video games or real-time systems.

10. A high-level language might not be ideal for writing a program that directly accesses a printer port because these languages often don't provide the level of control needed to interact with hardware directly.

11. Assembly language is not usually used when writing large application programs because it is much more complex and time-consuming to write than high-level languages. It also lacks many of the features that make high-level languages easier to work with, like object orientation and garbage collection.

12. Translating the C++ expression "X = (Y * 4) - 3" to assembly language would depend on the specific assembly language being used. However, a general translation might look something like this:

LOAD R1, Y
MULT R1, 4
SUB R1, 3
STORE X, R1

This loads the value of Y into register R1, multiplies it by 4, subtracts 3, and then stores the result in X.
