Q : Which of the following is not an OS?
(A) DOS
(B) MUS
(C) UNIX
(D) None of the above
"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.

Which cobble is used to send modulated light?
(A) Category 3 UTP
(B) Category 5 UTP
(C) fiber
(D) coax
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.
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
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.
Which device is designed to send packets using package addresses?
(A) Specialty Hub
(B) switching hub
(C) Port Hub
(D) filtering hub
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.
Which language is called 'foundation stone' for teaching languages like FORTRAN, ALGOL, PASCAL etc.?
(A) BASIC
(B) COBOL
(C) FORTRAN
(D) none of these
Computer language FORTRAN is useful in which field?
(A) business
(B) Drawing
(C) Science
(D) Commerce
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.
What is the computer language COBOL useful for?
(A) Professional work
(B) Graphic work
(C) Scientific work
(D) none of these
Which is the fastest printer?
(A) Laser Printer
(B) Jet printer
(C) Thermal Printer
(D) Daisy wheel printer
What is Oracle?
(A) an operating system
(B) word processor software
(C) Database software
(D) none of these
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.
