The micro-operations in computers are classified into the following categories:

Register transfer micro-operations: These type of micro operations are used to transfer from one register to another binary information.
Arithmetic micro-operations: These micro-operations are used to perform on numeric data stored in the REGISTERS some arithmetic operations.
Logic micro-operations: These micro operations are used to perform bit style operations / MANIPULATIONS on non numeric data.
Shift micro operations: As their NAME suggests they are used to perform shift operations in data STORE in registers.
