Program Plan Intro
Data replication in a distributed system:
- In the distributed
database management, the main advantage is the availability of the system, so that the user who uses the data most, can avail it easily. - To make it possible, the distributed database system replicates the data in the database because in case one system fails, the data will available in another site.
Remote backup site:
- Remote backup site searches for the server 's content and takes backup of the data that could be used for future purposes in case of data failure or device crashes.
- Remote backup site avoids data loss by making a copy of data.

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forward
- We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.arrow_forwardConsider the following Turing Machine (TM).
