Top 100 Basic Computer Questions and Answers

Correct Answer : A
Explanation :

The motherboard controls communications for the entire computer system. The main printed circuit board (PCB) in a computer is called the motherboard. All components and external peripherals connect to a computer's motherboard, which serves as its main communications hub.

Correct Answer : B
Explanation :

1. Digital Versatile Disc (DVD), sometimes also known as Digital Video Disc (DVD), is an optical disc storage media format for storing digital data.

2. DVD offers higher storage capacity than compact disc (CD) when having the same size.

3. It is a digital optical dose storage format. It can be used for storing video, audio, images or data.

Correct Answer : B
Explanation :

"MUS" is not a recognized operating system abbreviation in common use. Operating systems are software programs that manage computer hardware and provide services for computer programs. Examples of well-known operating systems include Windows, macOS, Linux, and Unix. "MUS" does not correspond to any widely used operating system.

Correct Answer : C
Explanation :

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.

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.

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.

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.

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.

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.
