Q :  

Which cobble is used to send modulated light?

(A) Category 3 UTP

(B) Category 5 UTP

(C) fiber

(D) coax

Correct Answer : C
Explanation :

It seems there might be a confusion in your question. If you are referring to the technology used for transmitting data using modulated light, the term you are looking for is "fiber optic cable" or simply "fiber." Fiber optic cables are thin, flexible strands of glass or plastic that transmit data as modulated light pulses. They are widely used for high-speed data transmission over long distances due to their ability to carry large amounts of data with low attenuation and high bandwidth capabilities.


Q :  

Computer language FORTRAN is useful in which field?

(A) business

(B) Drawing

(C) Science

(D) Commerce

Correct Answer : C
Explanation :

FORTRAN (short for "Formula Translation") is a high-level programming language that is particularly well-suited for scientific and engineering applications. It was developed for numeric and scientific computing and is widely used in fields such as physics, engineering, mathematics, and other scientific disciplines. FORTRAN allows for efficient processing of mathematical and scientific computations, making it a popular choice for complex scientific simulations, mathematical modeling, and computational research.


Q :  

What is Oracle?

(A) an operating system

(B) word processor software

(C) Database software

(D) none of these

Correct Answer : C
Explanation :

Oracle is a multinational computer technology corporation that specializes in developing and marketing database software and technology, cloud-engineered systems, and enterprise software products. One of its primary offerings is the Oracle Database, which is a widely used relational database management system (RDBMS). Oracle Database is designed to handle large volumes of data and complex transactions, making it popular among enterprises for various applications, including online transaction processing (OLTP), data warehousing, and business intelligence.


Q :  

Which language is called 'foundation stone' for teaching languages like FORTRAN, ALGOL, PASCAL etc.?

(A) BASIC

(B) COBOL

(C) FORTRAN

(D) none of these

Correct Answer : A
Explanation :
The language considered the "foundation stone" for teaching languages like FORTRAN, ALGOL, PASCAL, and many others is ALGOL (Algorithmic Language). ALGOL was a significant early programming language that influenced the design of subsequent programming languages, providing important concepts and structures used in the development of languages like FORTRAN, PASCAL, and C. While BASIC is also a widely used beginner-friendly programming language, ALGOL had a substantial impact on the development of programming language theory and design.



Q :  

Which command is used to remove a table from the database in SQL?

(A) DELETE TABLE

(B) DROP TABLE

(C) ERASE TABLE

(D) UNATTACH TABLE

Correct Answer : B
Explanation :
In SQL, the DROP TABLE command is used to remove a table from the database. When you execute DROP TABLE, it deletes the table along with all its data, indexes, triggers, constraints, and permissions. It should be used with caution as it permanently removes the table and all associated objects from the database.



Q :  

While using a database management system, the first thing you have to do is ________.

(A) Create a database file

(B) Activate file editor

(C) Load the software into your computer

(D) Keep a floppy disk in readiness

Correct Answer : C
Explanation :

While using a database management system, the first thing you have to do is install the software on your computer. Loading the software involves the installation process, which includes copying the necessary files and configuring the system to run the database management software effectively. Once installed, you can then create databases, define data structures, and start working with the DBMS to manage your data.


Q :  

What is virus that spreads in computer?

(A) It is hardware

(B) It is a computer program

(C) It is system software

(D) It is a windows tool

Correct Answer : B
Explanation :

a virus that spreads in a computer is a type of malicious computer program. Computer viruses are software programs designed to replicate themselves and spread from one computer to another. They can attach themselves to legitimate programs or documents, and when the infected program or document is executed, the virus activates and starts spreading to other files and systems. Viruses can cause various harmful effects, such as corrupting or deleting files, stealing sensitive information, or disrupting computer operations. Antivirus software and best practices, such as avoiding suspicious downloads and email attachments, are used to protect computers from these malicious programs.


Q :  

When does Time Bomb happen?

(A) during a particular logic and data

(B) during a particular date or time

(C) during a particular time

(D) none of the above

Correct Answer : B
Explanation :

it can be programmed to activate during a particular date or time, making it a significant threat if it goes undetected until the specified trigger conditions are met. Time bombs are often used by attackers to initiate their malicious activities at a specific moment, adding an element of surprise and making it difficult to prevent or mitigate the damage.


Q :  

What is it called when more than one if-statement is used together?

(A) if-else statement

(B) nested statement

(C) more if statements

(D) None of the above

Correct Answer : B
Explanation :
Certainly! A nested if statement refers to an if statement that is placed inside another if statement or other control structures. It allows for more specific conditions and complex decision-making in a program. The inner if statement is only executed if the outer if statement's condition is true.



Q :  

With which of the following is the Break statement used?

(A) if Statement

(B) else if Statement

(C) Switch Statement

(D) None of these

Correct Answer : C
Explanation :
The break statement is used with loops (such as for and while loops) and switch statements in programming. In loops, it is used to exit the loop prematurely, while in a switch statement, it is used to exit the switch block after executing a specific case.
