1. Which of the following kernel supports the MC68000 family?
A. pSOS+
B. pSOS+kernel
C. pNA+ network-manager
D. pSOS multiprocessor kernel
Answer: A
The pSOS+ kernel supports many processor families like Intel 80×86, M88000, MC68000, and i960 processors. The kernel is small in size and has a 15-20 Kbytes RAM.
2. What is the worst-case figure for interrupt latency for an MC68020 running at 25MHz?
A. 19 microseconds
B. 6 microseconds
C. 20 microseconds
D. 8 microseconds
Answer: B
The worst-case figure for the interrupt latency for an MC68020 which runs at 25MHz is 6 microseconds and the context switch for the same is 19 microseconds.
3. Which of the following is the multiprocessing version of the kernel?
A. pSOS+
B. pSOS+ kernel
C. pSOS multiprocessor kernel
D. pSOS
Answer: C
The pSOS+ is a multitasking real-time kernel of the operating system and the pSOS+m or the pSOS+ multiprocessor kernel is the multiprocessing version of the kernel. It is virtually the same as the single processor version except for the ability to send and receive system objects from the processors within the system.
4. Which of the following is a compiler-independent run-time environment for C applications?
A. pSOS multiprocessor kernel
B. pSOS
C. pSOS+
D. pREC+ runtime support
Answer: D
The pREC+ is a compiler-independent runtime environment for the C program applications.
5. Which kernel provides 88 functions that can be called from the C programs?
A. pSOS multiprocessor kernel
B. pSOS
C. pSOS+
D. pREC+ runtime support
Answer: D
The pREC+ is compatible with the ANSI X3J11 and can provide the 88 functions that can be called from the C programs.
6. Which of the following is not a standalone product?
A. pREC+ runtime support
B. pSOS+m
C. pSOS+
D. pSOS+ kernel
Answer: A
The pREC+ is not a standalone product it uses pSOS+m or pSOS+ for the input/output devices and task functions and calls the PHILE+ for the file and disk I/O.
7. Which kernel allows the multiple tasks which use the same routine?
A. pREC+ runtime support
B. pSOS+m
C. pSOS+
D. pSOS+ kernel
Answer: A
The pREC+ runtime support kernel’s routines are reentrant that allowing the multiple tasks to use the same routine simultaneously.
8. Which provides the TCP/IP communication over the ethernet and FDDI?
A. pSOS+m
B. pSOS+ kernel
C. pNA+ network-manager
D. pSOS+
Answer: C
A pNA+ network manager is a networking option that can provide TCP/IP communication over a large variety of media such as the FDDI and the ethernet.
9. Which can provide efficient downloading and debugging communication between the host and target system?
A. pSOS+
B. pSOS+ kernel
C. pHILE+ file system
D. pNA+ network-manager
Answer: D
The pNA+ network manager can provide efficient downloading and debugging communication between the host and target system.
10. Which of the following is a system-level debugger that provides the low-level debugging facilities and the system debugging?
A. pROBE+ system-level debugger
B. pNA+ network-manager
C. pHILE+ file system
D. pNA+ network-manager
Answer: A
The pROBE+ system-level debugger can provide the system debugging and the low-level debugging.
