This set of Embedded Systems Question Bank focuses on “Characteristics of Windows NT-II”.
1. What does LPC stand for?
a) local procedure call
b) local program call
c) local program code
d) local procedure code
View Answer
Explanation: The LPC is defined as the local procedure call which is responsible for coordinating the system calls from the WIN32 subsystem and an application.
2. Which of the following is responsible for coordinating the system call within an application and the WIN32 subsystem?
a) kernel
b) file system
c) LPC
d) network support
View Answer
Explanation: The local procedure call is responsible for coordinating the system calls from the WIN32 subsystem and an application. Depending upon the type of the system call, the application will be routed directly with the LPC without going through the WIN32 subsystem.
3. Which of the following is responsible for ensuring correct operation of all processes which are running within the system?
a) kernel
b) file system
c) lpc
d) user mode
View Answer
Explanation: The kernel is responsible for ensuring the correct operation of all process which are running within the system. It also provides the synchronisation and the scheduling that the system needs.
4. How many level priority scheme does the scheduling used in the kernel?
a) 8
b) 16
c) 32
d) 64
View Answer
Explanation: The scheduling support in the kernel support 32 level priority scheme and it can be used to schedule threads rather than processes.
5. Which procedure in the kernel allows the thread to wait until a specific resource is available?
a) synchronisation
b) scheduling
c) scheduling and synchronisation
d) lpc
View Answer
Explanation: The synchronisation procedure will allow the thread to wait until a specific resource such as semaphore, object etc are available.
6. Which of the following can preempt the current thread and reschedule the high priority thread in the kernel?
a) interrupt
b) lpc
c) file system
d) memory
View Answer
Explanation: The interrupts and the similar events such as exceptions can pass through the kernel which can preempt the current thread and the can reschedule the high priority thread to process.
7. How many file system does the Windows NT support?
a) 4
b) 5
c) 3
d) 2
View Answer
Explanation: The Windows NT support three file system and these coexist with each other even though there are some restrictions.
8. What does FAT stand for?
a) file address table
b) file access table
c) file arbitrary table
d) file allocation table
View Answer
Explanation: The FAT or file allocation table is a kind of file system which is used by the Windows 3.1 and the MS-DOS.
