And as most of the execution time is taken by actual work (instead of waiting), and the work in a computer is done by a <abbr title="Central Processing Unit">CPU</abbr>, they call these problems "CPU bound".

---

Common examples of CPU bound operations are things that require complex math processing.

For example:

* **Audio** or **image processing**.

 *   <li>Convert between specific preset values using {@link
 *       com.google.common.collect.Maps#asConverter Maps.asConverter}. For example, use this to
 *       create a "fake" converter for a unit test. It is unnecessary (and confusing) to <i>mock</i>
 *       the {@code Converter} type using a mocking framework.
 *   <li>Pass two lambda expressions or method references to the {@link #from from} factory method.

## 7. Testing Strategy

### 7.1 Unit Tests
```java
@Test
public void testWitnessRegistration() {
    WitnessRegistration registration = new WitnessRegistration(
        "\\\\server\\share", 
        InetAddress.getByName("192.168.1.100"),

import java.util.Random;
import java.util.SortedMap;
import java.util.concurrent.atomic.AtomicInteger;
import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;
import org.jspecify.annotations.NullMarked;
import org.jspecify.annotations.Nullable;

/**
 * Unit test for {@link MinMaxPriorityQueue}.
 *
 * @author Alexei Stolboushkin
 * @author Sverre Sundsdal
 */

E a maior parte do tempo de execução é tomada por trabalho real (ao invés de ficar esperando), e o trabalho em um computador é feito pela <abbr title="Central Processing Unit – Unidade Central de Processamento">CPU</abbr>. Eles chamam esses problemas de "limitados por CPU".

Exemplos comuns de operações limitadas por CPU são coisas que exigem processamento matemático complexo.
