Q221.

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

Responsible for the low-level graphics engine

Responsible for processing user input

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

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?

Responsible for the low-level graphics engine

Responsible for processing user input

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

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?

KERNEL32.DLL

USER32.DLL

GDI32.DLL

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?

Using direct calls

Using system calls

Using messaging

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?

Kernel object manager

Their own little object manager mechanism

Object-oriented programming

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?

In a separate process's address space

In kernel memory only

In both kernel memory and each process's address space

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?

Global

Local

Both a and b

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?

Yes, always

No, never

It depends on the specific object type

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 function that immediately jumps to a special condition in a program

A function that decides how to deal with an exception

A function that generates exceptions in order to report an error

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?

Software and hardware exceptions

Programming and system exceptions

Fatal and non-fatal exceptions

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.
