Definition Flip

Define the term 'automation' in the context of computer science.

Answer Flip

Automation is the use of technology to perform tasks with minimal human intervention. It increases efficiency and reduces errors,

Example: automating the assembly line in a car factory.
Definition Flip

Explain the function of a 'sensor' within an automated system, providing a practical example.

Answer Flip

A sensor detects changes in the environment and converts them into electrical signals. For instance, a temperature sensor in a central heating system measures the room's temperature.

Definition Flip

What is the purpose of an 'actuator' in an automated system? Provide an example.

Answer Flip

An actuator is a device that controls a mechanism or system, often based on signals from a control system. An example is a motor that controls the robotic arm in a manufacturing plant.

Definition Flip

Describe the role of 'feedback' in a closed-loop automated control system.

Answer Flip

Feedback is the process of taking the output of a system and using it to adjust the input, ensuring the system operates correctly.

Example: a thermostat monitors temperature and adjusts the heater accordingly.
Definition Flip

Explain what a 'control system' is and outline its key components.

Answer Flip

A control system manages, commands, directs or regulates the behavior of other devices or systems. It usually consists of sensors, a controller (microprocessor), and actuators.

Definition Flip

What is an 'embedded system', and where might you find one?

Answer Flip

An embedded system is a specialized computer system designed to perform a specific task within a larger system. They are commonly found in devices like washing machines, cars, and medical equipment.

Definition Flip

Distinguish between a 'microprocessor' and a 'microcontroller'.

Answer Flip

A microprocessor is a central processing unit (CPU) on a single integrated circuit, while a microcontroller integrates a CPU with peripherals like memory and I/O interfaces. Microcontrollers are often used in embedded systems.

Key Concept Flip

Describe the process of a robot arm picking up an object in a factory (include relevant keywords).

Answer Flip

The robot arm uses sensors to detect the object's position. A microcontroller processes this data and controls actuators (motors) to move the arm and gripper. Feedback from the sensors ensures accurate object retrieval.

Key Concept Flip

Explain how automation can improve the efficiency of a manufacturing process.

Answer Flip

Automation reduces human error, increases speed and throughput, and allows for continuous operation. This leads to higher productivity and lower production costs compared to manual processes.
