process(CLK)

In VHDL, a process is a basic unit of concurrent execution that describes a piece of sequential logic. The `process(CLK)` line indicates that the process is sensitive to changes on the `CLK` signal, which means that the process will execute whenever there is a rising or falling edge on the clock signal.
Here is an example VHDL process that is sensitive to the `CLK` signal:
```
process (CLK)
begin
if rising_edge(CLK) then
-- Do something on the rising edge of the clock
end if;
end process;
```
In this example, the process is triggered on the rising edge of the clock signal using the `rising_edge` function. The process can contain any kind of sequential logic, such as registers, counters, or state machines, and it will execute on each rising edge of the clock signal.
