Answer : 3. "fiber"
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.

Answer : 2. "switching hub"
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.

Answer : 3. "Science"
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.

Answer : 1. "Laser Printer"
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.

Answer : 1. "Professional work"
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.
Q: Which language is called 'foundation stone' for teaching languages like FORTRAN, ALGOL, PASCAL etc.?

Answer : 1. "BASIC"
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: What is the key combination to move down one paragraph in MS PowerPoint?

Answer : 3. "ctrl+down arrow "
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.
