Answer:
Explanation:
Given, total payload is: 2000 bytes
MTU is: 1500 bytes
Header is: 20 bytes
Base header is: 40 bytes
Total number of fragments = Total Payload / MTU
= 2500 / 1500
= 2 fragments
Fragment Base header Fragmentation header Authentication
header + Data
1 40 bytes 8 bytes 20 bytes +772bytes
2 40 bytes 8 bytes 792 bytes
Answer:
Check the explanation
Explanation:
Selecting the bio-metric technique fingerprint, it requires a scanner to read the fingerprint The cost for a scanner is in between 1000 and 5000 Placing two scanners at two entrance of office win cost bellow 10,000 So the cost needed for this technique is medium as compared with other bio-metric techniques
Attacks on this technique can be in saner, channel from scanner to feature extractor, in feature extractor, way in between feature extractor and marcher, in marcher, in database etc this attacks can be protect by using security methods such as cryptography, hashing, watermarking, noses etc
By using watermarking, cryptography and stenography methods, fingerprint has less false detection rate I e it gives high accuracy
I recommend fingerprint technique. Because of it is a standard technique, it has good accuracy and cost is less, and easy to handle, and it is taking small storage space in database.

Answer: serializability and isolation
Explanation: A database system that is also known as the database management system(DBMS) which is a system that is responsible for the data storage interface. It has the capability of storing large data units and can has interface language which is easy to maintain connection/interface.
When there is one execution cycle in database ,then serial order of the database is maintained automatically with the isolation feature because there will be only one cycle for the execution and ensuring that no error arises.
Answer:
=F5*$F$12+F5
Explanation:
If we want to increment the salaries in the cell F5, we must multiply the cell F5 by cell F12, and then we must sum that result.
If we want to drag the formula from the cell F5 to F10, we must use the dollar symbol $ to apply the same percent in our formula.
For example:
F12 = 5% = 0.05
F5 = 10,000
=F5*$F$12+F5
=10,000×0.05+10,000 = 10,500
