Q221.
What is the role of the USER component in the Win32 subsystem?

a.

Responsible for the low-level graphics engine

b.

Responsible for processing user input

c.

Responsible for higher-level GUI constructs such as windows and menus

d.

None of the above

Discuss
Answer: (c).Responsible for higher-level GUI constructs such as windows and menus Explanation:The USER component is responsible for higher-level GUI constructs such as windows and menus, as well as processing user input.
Q222.
What is the role of the GDI component in the Win32 subsystem?

a.

Responsible for the low-level graphics engine

b.

Responsible for processing user input

c.

Responsible for higher-level GUI constructs such as windows and menus

d.

None of the above

Discuss
Answer: (a).Responsible for the low-level graphics engine Explanation:The GDI component is responsible for the low-level graphics engine.
Q223.
Which kernel component is responsible for implementing the Win32 subsystem?

a.

KERNEL32.DLL

b.

USER32.DLL

c.

GDI32.DLL

d.

WIN32K.SYS

Discuss
Answer: (d).WIN32K.SYS Explanation:The Win32 subsystem is implemented inside the WIN32K.SYS kernel component.
Q224.
How is communication between the user-mode DLLs and the kernel component performed in the Win32 subsystem?

a.

Using direct calls

b.

Using system calls

c.

Using messaging

d.

None of the above

Discuss
Answer: (b).Using system calls Explanation:Communications between the user-mode DLLs and the kernel component in the Win32 subsystem is performed using conventional system calls.
Q225.
What is the object management mechanism used by USER and GDI?

a.

Kernel object manager

b.

Their own little object manager mechanism

c.

Object-oriented programming

d.

None of the above

Discuss
Answer: (b).Their own little object manager mechanism Explanation:USER and GDI use their own little object manager mechanism instead of the kernel object manager.
Q226.
How are handles to Win32 objects stored in USER and GDI?

a.

In a separate process's address space

b.

In kernel memory only

c.

In both kernel memory and each process's address space

d.

In a shared object table between USER and GDI

Discuss
Answer: (c).In both kernel memory and each process's address space Explanation:Handles to Win32 objects such as windows and device contexts are stored and managed in kernel memory, but are also mapped into each process’s address space for read-only access from user mode.
Q227.
Are USER and GDI handles global or local?

a.

Global

b.

Local

c.

Both a and b

d.

None of the above

Discuss
Answer: (a).Global Explanation:Unlike kernel object handles, both USER and GDI handles are global. If more than one process needs to access the same objects, they all share the same handles.
Q228.
Does the Win32 subsystem allow more than one process to access the same objects?

a.

Yes, always

b.

No, never

c.

It depends on the specific object type

d.

It depends on the specific process

Discuss
Answer: (c).It depends on the specific object type Explanation:In reality, the Win32 subsystem doesn’t always allow more than one process to access the same objects; the specific behavior depends on the object type.
Q229.
What is an exception handler?

a.

A function that immediately jumps to a special condition in a program

b.

A function that decides how to deal with an exception

c.

A function that generates exceptions in order to report an error

d.

A function that terminates a program

Discuss
Answer: (b).A function that decides how to deal with an exception Explanation:An exception handler is a special function that is called when an exception occurs in a program. The handler decides how to deal with the exception, and can either resolve the problem and make the program continue from the same code position or resume execution from another position. The handler can also decide to terminate the program if the exception cannot be resolved.
Q230.
What are the two basic types of exceptions?

a.

Software and hardware exceptions

b.

Programming and system exceptions

c.

Fatal and non-fatal exceptions

d.

Synchronous and asynchronous exceptions

Discuss
Answer: (a).Software and hardware exceptions Explanation:The two basic types of exceptions are software exceptions and hardware exceptions. Hardware exceptions are generated by the processor, for example when a program accesses an invalid memory page or when a division by zero occurs. Software exceptions are generated when a program explicitly generates an exception in order to report an error.
