Which of the following is most efficient access procedure?

  1. (1) Random access

  2. (2) Static access

  3. (3) Dynamic access

  4. (4) Sequential access


Correct Option: D

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Random access - Random access refers to the ability to access data in any order, without the need to read through the entire dataset sequentially. While random access can be efficient for accessing specific data points, it may not be the most efficient access procedure for accessing large amounts of data.

Option B) Static access - Static access typically refers to accessing data that is stored in a fixed location or position. This access procedure may be efficient for accessing data that is organized in a static manner, but it may not be the most efficient for accessing dynamic or changing data.

Option C) Dynamic access - Dynamic access typically refers to accessing data that is stored in a dynamic or changing manner, where the location of the data may vary. This access procedure may be efficient for accessing dynamic or changing data, but it may not be the most efficient for accessing large amounts of data.

Option D) Sequential access - Sequential access refers to accessing data in a sequential or linear manner, where data is accessed one after the other in a specific order. This access procedure involves reading through the entire dataset sequentially, which may not be the most efficient for accessing specific data points. However, for accessing large amounts of data in a linear manner, sequential access can be the most efficient procedure.

The correct answer is D) Sequential access. This option is correct because sequential access is the most efficient access procedure for accessing large amounts of data in a linear manner.

Procedure pointers are data items defined by which of the following clause?

  1. (1) USING PICTURE Clause

  2. (2) The USAGE IS FUNCTION-POINTER clause

  3. (3) The USAGE IS PROCEDURE-POINTER clause

  4. (4) The USAGE IS FUNCTION-ADDRESS clause


Correct Option: C
Explanation:

To answer this question, the user needs to have knowledge about procedure pointers in COBOL.

Option A is incorrect because the USING PICTURE clause is used to define the picture of data items.

Option B is incorrect because the USAGE IS FUNCTION-POINTER clause is used to define function pointers, not procedure pointers.

Option C is the correct answer. The USAGE IS PROCEDURE-POINTER clause is used to define procedure pointers in COBOL. Procedure pointers are data items that store the addresses of procedures.

Option D is incorrect because the USAGE IS FUNCTION-ADDRESS clause is used to define a data item that stores the address of a function, not a procedure.

Therefore, the answer is:

The Answer is: C. (3) The USAGE IS PROCEDURE-POINTER clause.

  1. (1) Using 5 to 9 digits is 35% faster than using 1 to 4 digits.

  2. (2) Using 10 to 18 digits is 2200% slower than using 1 to 4 digits.

  3. (3) using an odd number of digits is 5% to 20% faster than using an even number of digits

  4. (4) Using the 16 to 18 digits is up to 140% slower than using 1 to 15 digits


Correct Option: B

In a COBOL program it is possible to specify another entry point at which a program will begin running by using the ENTRY label in the called program, it is called as?

  1. (1) Dynamic entry point

  2. (2) Alternate entry point

  3. (3) Static entry point

  4. (4) Normarl enrty Point


Correct Option: B
Explanation:

To answer this question, the user needs to know about COBOL programs, entry points, and the use of the ENTRY label.

The ENTRY label in a COBOL program is used to specify another entry point at which a program will begin running. This allows the program to be executed from different starting points within the same program. The use of an alternate entry point enables a program to be divided into smaller, more manageable components.

Now, let's go through each option and explain why it is right or wrong:

A. (1) Dynamic entry point: This option is incorrect. Dynamic entry point refers to the ability of a program to call another program or subroutine at run time, rather than at compile time.

B. (2) Alternate entry point: This option is correct. The use of the ENTRY label in a COBOL program specifies an alternate entry point at which a program will begin running.

C. (3) Static entry point: This option is incorrect. A static entry point is a fixed starting point within a program that is determined at compile time.

D. (4) Normal entry point: This option is incorrect. There is no such term as a normal entry point in COBOL programming.

Therefore, the answer is: B. (2) Alternate entry point
