Final answer:

In technology, events are detectable actions or occurrences that can trigger a response by a program. The four examples of events are moving a mouse, clicking a mouse button, a sensor detecting an earthquake, and scanning a credit card.

Step-by-step explanation:

An event in computer science and technology is an action or occurrence that can be detected by a program and which may trigger a response or a process. In the given options, there are four that qualify as events:

  1. Moving a mouse: This is an event because it is a physical action that can trigger a response in a computer system.
  2. Clicking a mouse button: Similar to moving a mouse, clicking is an actionable event that a computer program can detect and respond to.
  3. A sensor detecting the motion of an earthquake detector: This is considered an event because the sensor's detection is an occurrence that can prompt further actions, such as activating an alarm or recording data.
  4. Scanning a credit card when you shop: The act of scanning is an event that initiates a transaction process.

Adding three and four in a program is not considered an event in this context; it's simply an operation or function execution within the program.

Final answer:

In the context of programming and digital systems, events include moving a mouse, clicking a mouse button, a sensor detecting motion, and scanning a credit card. These events prompt a response or activity, unlike a simple operation like adding numbers.

Step-by-step explanation:

Among the provided options, the following are events:

  • Moving a mouse
  • Clicking a mouse button
  • A sensor detecting the motion of an earthquake detector
  • Scanning a credit card when you shop

Adding three and four in a program is not considered an event but rather an operation within the program. An event can be understood as an action or occurrence that may prompt a response or change, especially in the context of programming and digital systems. For example, the action of clicking a mouse button generates an event that might be used by a program to initiate a specific action. Similarly, the detection of an earthquake by a sensor is an event that might trigger alarms or automated safety procedures. Scanning a credit card involves the event of reading the card information, which further communicates with the payment systems to process a transaction.
