A serial schedule is when all the operations of one transactions appear together (not mixed with the operations of any other transactions on the schedule). A serializable schedule is a weaker term -- it is a schedule where the operations of different transactions may be mixed together on the schedule, so long as they are conflict-equivalent to some serial schedule.

Difference between serial and non-serial schedule?
Serial ScheduleNon-Serial ScheduleA serial schedule is a sequence of operation by a set of concurrent transaction that preserves the order of operations in each of the individual transactions.A non-serial schedule is a schedule where the operations of a group of concurrent transactions are interleaved.Transactions are performed in serial order.Transactions are performed in non-serial order, but result should be same as serial.No interference between transactionsConcurrency problem can arise here.It does not matter which transaction is executed first, as long as every transaction is executed in its entirely from the beginning to end.The problem we have seen earlier lost update, uncommitted data, inconsistent analysis is arise if scheduling is not proper.A serial schedule gives the benefits of concurrent execution without any problemIn this schedule there is no any benefit of concurrent execution.Serial schedule that does interleaved the actions of different transactions.Where non-serial schedule has no only fix actions of any transaction.EXAMPLE:If some transaction T is long, the other transaction must wait for T to complete all its operations.EXAMPLE:In this schedule the execution of other transaction goes on without waiting the completion of T.If we consider transaction to be independent serial schedule is correct based on (property ACID) above assumption is valid.The objective behind serializability is to find the non-serial schedule that allows transactions to execute concurrently without interfering one another.

What is the difference between Serial and Parallel Adder?
Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.
