Correct Option: A,B,C

In TPF data isolation can be achieved by

  1. Data Hiding

  2. Reentrancy

  3. Encapsulation

  4. None of the above


Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of TPF (Transaction Processing Facility) and data isolation.

TPF is an operating system designed for high-volume transaction processing. Data isolation refers to the ability to ensure that each transaction is executed in isolation from other transactions, meaning that the changes made by one transaction are not visible to other transactions until the changes are committed.

Let's go through each option to understand why it is correct or incorrect:

Option A) Data Hiding - Data hiding is a concept in object-oriented programming that refers to the practice of hiding the internal details of an object. While data hiding can help improve security and modularity, it is not directly related to achieving data isolation in TPF.

Option B) Reentrancy - Reentrancy refers to the ability of a program or subroutine to be invoked multiple times simultaneously or recursively. While reentrancy can help improve concurrency and efficiency, it is not directly related to achieving data isolation in TPF.

Option C) Encapsulation - Encapsulation is a concept in object-oriented programming that refers to the bundling of data and methods within a single unit. While encapsulation can help improve modularity and maintainability, it is not directly related to achieving data isolation in TPF.

Option D) None of the above - Since options A, B, and C are incorrect, the correct answer must be option D, None of the above.

The correct answer is D) None of the above. None of the options listed directly relate to achieving data isolation in TPF.

Correct Option: A

How many sections an easytrieve program contains and what are they?

  1. 3;Identification,Environment, Procedure

  2. 4;Cofiguration, Input Output, File section, Procedure

  3. 3;Environment, Library, Activity

  4. 3; Configuration, File section, Procedure


Correct Option: C

Which is the only mandatory section of an easytrieve program?

  1. Activity

  2. Identification

  3. Procedure

  4. Environent


Correct Option: A

AI Explanation

To answer this question, you need to understand the structure of an Easytrieve program.

Option A) Activity - This option is correct because the Activity section is the only mandatory section of an Easytrieve program. The Activity section contains the main logic and processing instructions of the program.

Option B) Identification - This option is incorrect because the Identification section is not mandatory. The Identification section is used to provide information about the program, such as the program name and author.

Option C) Procedure - This option is incorrect because the Procedure section is not mandatory. The Procedure section is used to define reusable code segments that can be called from different parts of the program.

Option D) Environment - This option is incorrect because the Environment section is not mandatory. The Environment section is used to specify file definitions and other environmental settings for the program.

The correct answer is A) Activity. This option is correct because the Activity section is the only mandatory section of an Easytrieve program, containing the main logic and processing instructions.

An easytrieve file is defined as given. NAME * 10 A What does '*' indicates here?

  1. It does not indicates anything , it is a syntax error.

  2. It indicates that the field will begin in next position.

  3. It indicates that no data record is present before 'NAME'.

  4. It indicates no data record exists after 'NAME'.


Correct Option: B

What are the two processing activities in an easytrieve program?

  1. JOB activity, LOOP activity

  2. PROCEDURE activity, SECTION activity

  3. JOB activity, SORT activity

  4. STATEMENT activity, PARAGRAPH activity


Correct Option: C

Can there be more than one activity in a single easytrieve program?

  1. True

  2. False
