ARPANET was the network that became the basis for the Internet. Based on a concept first published in 1967, ARPANET was developed under the direction of the U.S. Advanced Research Projects Agency (ARPA). In 1969, the idea became a modest reality with the interconnection of four university computers. The initial purpose was to communicate with and share computer resources among mainly scientific users at the connected institutions. ARPANET took advantage of the new idea of sending information in small units called packets that could be routed on different paths and reconstructed at their destination. The development of the TCP/IP protocols in the 1970s made it possible to expand the size of the network, which now had become a network of networks, in an orderly way.

A relationship, in the context of databases, is a situation that exists between two relational database tables when one table has a foreign key that references the primary key of the other table. Relationships allow relational databases to split and store data in different tables, while linking disparate data items.
For example, in a bank database a CUSTOMER_MASTER table stores customer data with a primary key column named CUSTOMER_ID; it also stores customer data in an ACCOUNTS_MASTER table, which holds information about various bank accounts and associated customers. To link these two tables and determine customer and bank account information, a corresponding CUSTOMER_ID column must be inserted in the ACCOUNTS_MASTER table, referencing existing customer IDs from the CUSTOMER_MASTER table. In this case, the ACCOUNTS_MASTER table’s CUSTOMER_ID column is a foreign key that references a column with the same name in the CUSTOMER_MASTER table. This is an example of a relationship between the two tables.
Answer: B) Collision Resistance
Explanation: A hash algorithm is the function that works by changing the string of data into the string of numeric values. The numeric values that are obtained are of the fixed length.
The collision is the attack in found when the produced outcome is same for the two different string inputs. The hash algorithm has the ability to resist the collision by the cryptography technique . Cryptographic hash function are is for maintaining the authenticity of the input function.
Thus, the correct option is option(B). The other option are collision avoidance refers as the escaping the collision ,collision strength refers to the strength ability of collision and collision metric refers to pattern of collision, which are incorrect.
