3. Hardwired
Control Unit
• This type of control unit is built directly
into the hardware of the computer. It
uses a fixed set of instructions to control
the data flow within the CPU (Central
Processing Unit). Think of it like a set of
rules hardwired into the computer's
circuits that can't be changed.

4. Microprogrammed
Control Unit
• Microprogrammed control units use
microcode, which is a set of instructions
stored in memory. This allows for more
flexibility since the control unit's
behavior can be changed by modifying
the microcode.
