Question

Difference between lock based protocol and timestamp based protocol

Answer 1

Timestamp-based Protocols:- The most commonly used concurrency protocol is the timestamp based protocol. ... Lock-based protocols manage the order between the conflicting pairs among transactions at the time of execution, whereas timestamp-based protocols start working as soon as a transaction is created.

Answer 2

Difference between lock based protocol and timestamp-based protocol is given below:-

Explanation:

Lock-based protocol

• Lock-based protocols control the balance between competing pairs of payments at the time of operation.
• A lock is a process for controlling sequential access to a data item.
• Locking protocol is a set of rules accompanied by all exchanges while asking for and distributing locks. Locking protocols limit the number of possible timetables.

Timestamp based protocol

• Timestamp-based protocols will start to work as soon as a transaction is made.
• Each transaction has a date stamp connected with it, and the order is determined by the maturity of the transactions.
• The Timestamp Ordering Protocol is being used to schedule transfers depending on their Timestamps to evaluate the time span of the payment, this method uses device time or logical clock.
