Answer:
The difference between the centralized and the distributed database architecture are as follows:
- The centralized database is the type of database which works on the single file in the database. Whereas, the distributed database works with the multiple files in the database.
- The centralized database refers to the proper planning and the helps in the decision making in the management system. Whereas, in the distributed database system the data are mainly distributed in the multiple files and the user can easily access the near by file in the database system.
- In the centralized database, if the database are get fail then the overall system come to halt. On the other hand in the distributed system, if the component get failed then the performance of the system are get reduced.
Answer:
Yess the answer is correct
Explanation:
Answer:
The answer is below
Explanation:
A) The total bandwidth = 1 Mbps = 1000 Kbps
The requirement for each user = 100 Kbps
Total number of users = Total bandwidth / requirement for each user
Total number of users = 1000 Kbps / 100 Kbps = 10 users
B) Since each user transmits only 10 percent of the time, probability that a given user is transmitting is:
Probability = 0.1
C) Binomial distribution formula is given by:
Hence:
Probability=
D) The probability that there are 11 or more is:
