Computer General Knowledge Quiz Questions and Answers for Competitive Exams
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.
Which device is designed to send packets using package addresses?
(A) Specialty Hub
(B) switching hub
(C) Port Hub
(D) filtering hub
Correct Answer : B
Explanation :
A switching hub, also known as a network switch, is designed to send packets using package addresses. A network switch operates at the data link layer of the OSI model and uses MAC addresses to forward data frames to specific devices within a local area network (LAN). Unlike a hub, which simply broadcasts data to all devices in the network, a switch intelligently forwards packets only to the device intended to receive the data, increasing network efficiency and reducing unnecessary network traffic.
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.
Which is the fastest printer?
(A) Laser Printer
(B) Jet printer
(C) Thermal Printer
(D) Daisy wheel printer
Correct Answer : A
Explanation :
Laser printers are generally known for their speed and efficiency, making them one of the fastest types of printers available for everyday office use. They use laser technology to print text and images, which allows for high-speed printing without compromising print quality. Laser printers are especially well-suited for printing large volumes of text documents quickly and are commonly used in office environments where fast and high-quality printing is required.
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).

What is the computer language COBOL useful for?
(A) Professional work
(B) Graphic work
(C) Scientific work
(D) none of these
Correct Answer : A
Explanation :
COBOL (Common Business Oriented Language) is a high-level programming language primarily used for business, finance, and administrative systems within companies and governments. It is particularly useful for handling large-scale, data-centric applications in areas such as accounting, payroll, inventory management, and other business-related tasks. COBOL is known for its readability and ease of use, making it suitable for professionals working on applications that require extensive data processing and business logic. Despite being an older language, COBOL continues to be used in many legacy systems, especially in industries where stability and reliability are paramount.
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.
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.
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.
What is the key combination to move down one paragraph in MS PowerPoint?
(A) down arrow
(B) shift+down arrow
(C) ctrl+down arrow
(D) Alt+Down Arrow
Correct Answer : C
Explanation :
Actually, in MS PowerPoint (and most other word processing applications), the key combination to move down one paragraph is "Enter". Pressing the "Enter" key moves the cursor to the next paragraph. If you want to move the cursor down one line within the same paragraph, you can use the "Down Arrow" key. There isn't a specific default key combination to move down one paragraph in PowerPoint; it's more about using the "Enter" key to start a new paragraph.
