Solutions
S1. Ans.(c)
Sol. Database is stored in high capacity disc.
S2. Ans.(e)
Sol. All of the above are objective of DBMS.
S3. Ans.(b)
Sol. Structured Query Language. SQL is used to communicate with a database. According to ANSI (American National Standards Institute), it is the standard language for relational database management systems.
S4. Ans.(a)
Sol. An entity relationship model, also called an entity-relationship (ER) diagram, is a graphical representation of entities and their relationships to each other, typically used in computing in regard to the organization of data within databases or information systems.
S5. Ans.(e)
Sol. A desktop or laptop computer that is used on its own without requiring a connection to a local area network (LAN) or wide area network (WAN). Although it may be connected to a network, it is still a stand-alone PC as long as the network connection is not mandatory for its general use.
S6. Ans.(e)
Sol. The data that is provided by banks can be easily analyzed to find out if there is unusual activity in currency flow at an end point or the person using the currency, no matter whether it is happening at individual or regional level.
S7. Ans.(a)
Sol. Speech recognition (SR) is the inter-disciplinary sub-field of Artificial Intelligence.
S8. Ans.(d)
Sol. Data mining automates the process of finding predictive information in large databases.
S9. Ans.(b)
Sol. Embedded software is computer software, written to control machines or devices that are not typically thought of as computers. It is typically specialized for the particular hardware that it runs on and has time and memory constraints.
S10. Ans.(e)
Sol. SQL SERVER and MS ACCESS is Microsoft's DBMS to take on rivals Oracle.
