    Which is not impact printer?

    • A.

      Laser printer

    • B.

      Dot-matrix printer

    • C.

      Daisy wheel

    • D.

      Line printer

    Correct Answer
    A. Laser printer
    Explanation
    A laser printer is not an impact printer because it does not physically strike the paper to create an image. Instead, it uses a laser beam to transfer toner onto the paper, creating high-quality prints. In contrast, dot-matrix printers, daisy wheel printers, and line printers all use physical impact to create characters on the paper. Dot-matrix printers use a matrix of pins to strike an ink ribbon, while daisy wheel printers use a rotating wheel with characters on it. Line printers use a line of print hammers to strike the paper.

    Rate this question:

  • 3. 

    Which one is a sequential (series) access device?

    • A.

      Floppy disk

    • B.

      Magnetic tape

    • C.

      Compact disk

    • D.

      None of above

    Correct Answer
    B. Magnetic tape
    Explanation
    A magnetic tape is a sequential (series) access device because it stores data in a linear format that can only be accessed sequentially. To retrieve data from a magnetic tape, the tape must be wound or rewound to the specific location where the data is stored. This makes it suitable for applications that require large amounts of data to be stored and accessed sequentially, such as backup systems or archival storage. Floppy disks and compact disks, on the other hand, are random access devices, meaning that data can be accessed directly without the need to sequentially move through the storage medium.

    • D.

      Assembler

    Correct Answer
    A. Interpreter
    Explanation
    An interpreter is a program that translates and executes one line of code at a time. It reads each line, translates it into machine code or bytecode, and immediately executes it. This allows for a line-by-line execution and immediate feedback on any errors or issues encountered. In contrast, a compiler translates the entire program into machine code before execution, and an assembler translates assembly language into machine code. A translator is a more general term that can refer to any program that converts code from one language to another.
