Answer:
D. Applying strong encryption
Explanation:
Strong cryptography or cryptographic-ally strong are general terms applied to cryptographic systems or components that are considered highly resistant to cryptanalysis.One cryptographic cipher has been mathematically proven to be unbreakable when it is used correctly, but it is only very rarely used.
Answer:
log 5,6,7,8,9 is the binary number according to the computer
Answer: Time slicing
Explanation:
Time slicing is one of the technique that basically implement the multitasking in the operating system. It basically generate the interrupt and at the each clock of the interrupt in the operating system basically regain control and then assign that particular system or processor to the another user.
Time slice are typically work in milliseconds. By using the multi users system, the time slice is the total amount of the processing time for the each user get assigned.
Answer:
1. A. True
2. A. True
3. B. Conceptual.
4. Three (3).
Explanation:
An Entity-Relationship Model is used in databases to describe the structure and relationship between data elements known as entities.
1. True: In the Entity-Relationship Model, relationships can have attributes.
2. True: Attributes are the smallest division of data in ER diagram.
3. Conceptual: the level of abstraction which the Entity-Relationship Model most concerned with.
4. Consider the following relationship involving two entities, students and classes: A student can take many classes. A class can be taken by many students. The number of tables which can be used to represent this relationship in a schema is 3 because we are having three (3) parameters which are simply the students and the two entities.
In database management, the term "schema" is used to denote a representation of data.
A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
