Answer:
Sound
Explanation:
Dart is object oriented. It's sound feature helps to make codes more maintainable and readable. The sound type system means that one can never experience w state where where an expression would evaluate to a value that wouldn't match that expressions static type.
The sound system makes the code to be unambiguous. It makes the code to be easier to read as types cannot lie, also your code would be more maintainable since when a piece of code gets to be changed, you would be warned of other pieces that may have gotten broken.
Answer:
This is not true
Explanation:
The optimal Huffman code is used to encrypt and compress text files. It uses fixed-length code or variable-length code for encryption and compression of data.
The professor's character code is similar to Huffman's variable-length coding which uses variable length od binary digits to represent the word strings. The file size of the text file above is;
= 6 x 1 + 2 x 2 + 3 x 2 + 2 x 2 + 8 x 1 = 28 bits
This would be the same for both cases.
The encrypt would be the problem as the encoded and decoding of the characters B and E may cause an error.
Answer:
Option B is the correct answer for the above question.
Explanation:
- The data warehouse is a collection of large data or a database that includes historical and operational or current data. This database can be used to make the decisions for the prospects of the organization.
- The above question asked about to select the database which can collect the historical and operational data from various source. That type of database is a data warehouse that is described above. Hence option B is correct while the other is not because:-
- Option a states about data model which is used to define the database structure.
- Option c states about the relational database which is used to collect only current data.
- Option d states about the DBMS which is used to manage the relational database.
