Q21. Which of the following is a type of database model?
a) Relational
b) Object-oriented
c) Hierarchical
d) All of the above
Show Answer
Correct Answer: d) All of the above
Explanation: Relational, object-oriented, and hierarchical are all types of database models. The relational model organizes data into tables with rows and columns, the object-oriented model represents data as objects and their relationships, and the hierarchical model organizes data in a tree-like structure with parent-child relationships.
Q22. In a file processing system, what is the primary purpose of a file organization method?
a) To eliminate data redundancy
b) To manage the storage and retrieval of data in files
c) To process data in real-time
d) To organize data in a database
Show Answer
Correct Answer: b) To manage the storage and retrieval of data in files
Explanation: The primary purpose of a file organization method in a file processing system is to manage the storage and retrieval of data in files. File organization methods, such as sequential, indexed, and hierarchical, determine how data is stored, accessed, and managed within a file system, ensuring efficient data storage and retrieval.
Q23. What is the primary advantage of a database-oriented approach to data processing over a file-oriented approach?
a) Reduced data redundancy
b) Improved data isolation
c) Increased program or data dependency
d) Easier data access
Show Answer
Correct Answer: a) Reduced data redundancy
Explanation: The primary advantage of a database-oriented approach to data processing over a file-oriented approach is reduced data redundancy. By integrating related files and managing the relationships between data, a database-oriented approach helps maintain data integrity and consistency, making it easier to access, update, and manage data within an organization.
Q24. Which of the following is NOT a component of a Database Management System (DBMS)?
a) Data definition language (DDL)
b) Data manipulation language (DML)
c) Query language
d) File organization method
Show Answer
Correct Answer: d) File organization method
Explanation: A DBMS consists of several components, including data definition language (DDL), data manipulation language (DML), and query language. DDL is used to define the structure of the database, such as creating, altering, and deleting tables. DML is used to manipulate the data stored in the database, such as inserting, updating, and deleting records. Query language is used to retrieve data from the database based on specific criteria. File organization method is not a component of a DBMS, as it is related to file processing systems.
Q25. In a relational database, what is the term used to describe a collection of related data values?
a) Table
b) Record
c) Field
d) Attribute
Show Answer
Correct Answer: b) Record
Explanation: In a relational database, a collection of related data values is referred to as a record. Records, also known as tuples or rows, represent groups of related data values, with each value corresponding to a specific field or attribute in the table.
Q26. Which of the following is a type of file organization?
a) Sequential
b) Indexed
c) Hierarchical
d) All of the above
Show Answer
Correct Answer: d) All of the above
Explanation: Sequential, indexed, and hierarchical are all types of file organization methods. These methods determine how data is stored, accessed, and managed within a file system. Sequential file organization stores data in a linear sequence, indexed file organization uses an index to speed up data access, and hierarchical file organization arranges data in a tree-like structure.
Q27. What is the primary purpose of a data storage hierarchy?
a) To eliminate data redundancy
b) To manage file organizations
c) To organize data in a systematic manner
d) To process data in real-time
Show Answer
Correct Answer: c) To organize data in a systematic manner
Explanation: The primary purpose of a data storage hierarchy is to organize data in a systematic manner, often in a hierarchical form. Data organization involves characters, fields, records, files, and so on. The data storage hierarchy helps manage data efficiently and effectively, ensuring that data is easily accessible and retrievable.
Q28. Which of the following is a disadvantage of a file management system?
a) Data redundancy
b) Data isolation
c) Program or data dependency
d) All of the above
Show Answer
Correct Answer: d) All of the above
Explanation: A file management system has several disadvantages, including data redundancy, data isolation, and program or data dependency. Data redundancy occurs when the same data is stored in multiple files, leading to inconsistencies and increased storage requirements. Data isolation happens when data is scattered in different files, making it difficult to access and manage related data. Program or data dependency is a drawback where programs are dependent on the files and the files depend on the data, making it challenging to maintain and update the system.
Q29. In a file processing system, what is the smallest unit of data?
a) Bit
b) Byte
c) Field
d) Record
Show Answer
Correct Answer: a) Bit
Explanation: In a file processing system, the smallest unit of data is a bit. A bit is a binary digit, which can have a value of either 0 or 1. Bits are the fundamental building blocks of data storage and processing in computer systems.
Q30. Which of the following is a type of database model?
a) Network
b) Sequential
c) Indexed
d) Hierarchical
Show Answer
Correct Answer: a) Network
Explanation: A network database model is a type of database model that allows multiple relationships between entities, forming a complex network structure. Other types of database models include hierarchical, relational, and object-oriented models. Sequential and indexed are types of file organization methods, not database models.
