SystemVerilog Interview Question: Difference Between `logic` and `bit`

In SystemVerilog, the keyword `logic` is used to declare a variable that can represent multiple binary states, such as 0, 1, and X (unknown state), while the keyword `bit` is used to declare a variable that can only represent two states, 0 and 1.

The `logic` data type is more versatile and allows for modeling more complex digital logic behaviors, whereas the `bit` data type is more restrictive but can be more efficient in terms of memory usage.

It's important to choose the appropriate data type based on the requirements of the design and the desired behavior of the variable in SystemVerilog.
