Q11. 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.
Q12. What is the primary function of a file utility?
a) To manage data redundancy
b) To organize data in a database
c) To perform operations on files and directories
d) To process data in real-time
Show Answer
Correct Answer: c) To perform operations on files and directories
Explanation: File utilities are software tools that perform operations on files and directories, such as creating, deleting, copying, moving, and renaming files. They help manage and maintain the file system, ensuring efficient data storage and retrieval.
Q13. Which of the following is a component of a Database Management System (DBMS)?
a) Data definition language (DDL)
b) Data manipulation language (DML)
c) Query language
d) All of the above
Show Answer
Correct Answer: d) All of the above
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.
Q14. What is the main advantage of using a Database Management System (DBMS) over a file management system?
a) Improved data consistency
b) Reduced data redundancy
c) Enhanced data security
d) All of the above
Show Answer
Correct Answer: d) All of the above
Explanation: A DBMS offers several advantages over a file management system, including improved data consistency, reduced data redundancy, and enhanced data security. By managing the relationships between data and integrating related files, a DBMS helps maintain data integrity and consistency. It also reduces data redundancy by storing data in a centralized location, making it easier to access, update, and manage data within an organization. Additionally, a DBMS provides better data security by implementing access controls and other security measures.
Q15. Which of the following is NOT a method of organizing data?
a) File-oriented approach
b) Database-oriented approach
c) File management system
d) Data processing
Show Answer
Correct Answer: d) Data processing
Explanation: Data processing is not a method of organizing data; it is the process of converting raw data into meaningful information through various techniques. The file-oriented approach, database-oriented approach, and file management system are methods of organizing data, each with its advantages and disadvantages.
Q16. In a relational database, what is the term used to describe a single instance of a set of fields in a table?
a) Record
b) Field
c) Tuple
d) Both a) and c)
Show Answer
Correct Answer: d) Both a) and c)
Explanation: In a relational database, a single instance of a set of fields in a table is referred to as a record or tuple. Records or tuples represent groups of related data values, with each value corresponding to a specific field or attribute in the table.
Q17. 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.
Q18. 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.
Q19. 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.
Q20. 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.
