Computer Engineering Embedded Systems - CEES-501

1. Which of the following is NOT a characteristic of an embedded
system?
A. Dedicated function
B. High processing power
C. Real-time operation
D. Integration with hardware and software
Answer: B) High processing power
Rationale: Embedded systems are designed for specific tasks, and
processing power is typically lower compared to general-purpose
computers.

2. Which of the following is typically used in an embedded system to
interface with external devices?
A. Microprocessor
B. Microcontroller
C. Central Processing Unit
D. Random Access Memory
Answer: B) Microcontroller
Rationale: Microcontrollers are integrated with CPU, memory, and
peripheral interfaces, making them ideal for embedded applications.

3. An embedded system that interacts with physical components is
known as a:
A. Real-time system
B. Reactive system
C. Cyber-Physical System
D. Control system
Answer: C) Cyber-Physical System
Rationale: A Cyber-Physical System integrates computing with
physical processes, making it applicable to embedded systems
interacting with the environment.

4. Which of the following programming languages is commonly used in
embedded systems?

,A. Python
B. C
C. Java
D. Ruby
Answer: B) C
Rationale: C is commonly used in embedded systems because of its low-
level access to memory and efficient use of system resources.

5. In embedded systems, the primary role of the Watchdog timer is to:
A. Reset the system when a fault occurs
B. Enhance the system’s performance
C. Enable power saving features
D. Handle input/output operations
Answer: A) Reset the system when a fault occurs
Rationale: A watchdog timer is a safety feature used to reset the system
if it becomes unresponsive, preventing system hangs.

6. Which of the following is a feature of Real-Time Operating Systems
(RTOS)?
A. Multi-threading
B. Multitasking
C. Scheduling with priority
D. All of the above
Answer: D) All of the above
Rationale: RTOS is designed for real-time applications where tasks
need to be executed within precise timing constraints.

7. Which of the following is NOT a type of memory commonly used in
embedded systems?
A. ROM
B. Flash
C. EEPROM
D. Virtual Memory
Answer: D) Virtual Memory
Rationale: Embedded systems typically do not use virtual memory, as it
adds complexity, and embedded systems often require deterministic

, memory usage.

8. Which communication protocol is typically used for short-range
communication in embedded systems?
A. USB
B. Bluetooth
C. Ethernet
D. HDMI
Answer: B) Bluetooth
Rationale: Bluetooth is a widely used short-range wireless
communication protocol, ideal for embedded systems.

9. What is the primary function of an embedded system's Peripheral
Interface Controller (PIC)?
A. To store data
B. To provide network connectivity
C. To interface with external devices
D. To manage system memory
Answer: C) To interface with external devices
Rationale: A PIC is a microcontroller or a chip designed to control
peripherals and manage I/O interfaces in embedded systems.

10. The process of converting high-level language code to machine
language code in embedded systems is known as:
A. Compilation
B. Assembly
C. Linking
D. Emulation
Answer: A) Compilation
Rationale: Compilation is the process where high-level code is
translated into machine code that the embedded system can execute.

11. Which of the following is a feature of the ARM architecture used in
many embedded systems?
A. RISC (Reduced Instruction Set Computing)
B. CISC (Complex Instruction Set Computing)
