This device is referred to as a USB hub. It allows multiple devices to connect to a single USB port.

This process is called data mining. It involves analyzing large datasets to find meaningful patterns and insights.

The variable name that is NOT valid in Delphi is _dSalary. Variable names in Delphi cannot start with an underscore.

First, we perform the calculations step by step:

1. Calculate $25.0/6$: rac{25.0}{6} ext{ gives approximately } 4.1667 Thus, $ext{ceil}(4.1667) = 5$.

2. Next, calculate $30 ext{ mod } 6$: This results in $0$ since $30$ is a multiple of $6$.

3. Finally, calculate $round(15.0/4)$: rac{15.0}{4} = 3.75 ext{ which rounds to } 4.

Now putting it all together: $y = 5 + 0 - 4 = 1.$ Thus, the value of y is 1.
