Answer:

b. foreign key

Explanation:

In the database world, a foreign key is a field on one table and a primary key for another table. The purpose of a foreign key is to provide linkages between two or more tables. Given two tables A and B, and making A the point of reference, a primary key is a field that is unique in A while a foreign key is unique in B.

On another hand, a composite primary key is a combination of two or more fields/columns on database table that can be used to uniquely identify each row in the table.

In the database lingua, what we have is a unique key not a distinct key, though the two words are similar in meaning.

A duplicate key is used when an information may be repeatedly entered on a table.

So the correct option is a foreign key.

What is the exact number of bytes in system of memory that contains (a) 64K bytes (In Binary)(b) 32M bytes
VashaNatasha [74]

Answer:

64 K bytes = 65536 bytes

32 M bytes = 33554432 bytes

Explanation:

The question expect the number of bytes in binary instead of decimal. So this is important to understand that:

  • 1K bytes = 1024 bytes (in binary)

Therefore,

  • 64 Kb = 64 x 1024 =  65536 bytes

Using the similar calculation logic, we know

  • 1M bytes = 1024 x 1024 = 1048576 bytes (in binary)

Therefore,

  • 32 M bytes = 32 x 1048576 =  33554432 bytes
