    Computer Virus is ?

    • Windows Tool

    • A hardware

    • A computer programme

    • Combination of above two

    • None of the above

    Correct Answer
    A. A computer programme
    Explanation
    A computer virus is a type of malicious software that is designed to replicate itself and spread from one computer to another without the knowledge or consent of the user. It can cause harm to the infected computer by corrupting files, stealing personal information, or disrupting the normal functioning of the system. Therefore, the correct answer is "a computer programme" as it accurately describes the nature and purpose of a computer virus.

    Which of the following functions is not performed by CPU?

    • Graphical Display of data

    • Arithmetic calculations

    • Managing Memory

    • Managing Input and Output

    • None of these

    Correct Answer
    A. Graphical Display of data
    Explanation
    The CPU is responsible for performing arithmetic calculations, managing memory, and managing input and output. However, the graphical display of data is not a function typically performed by the CPU. This task is usually handled by the graphics processing unit (GPU) or dedicated graphics hardware.

    • RAM

    • ROM

    • Hard disk

    • Software

    • None of these

    Correct Answer
    A. Software
    Explanation
    Compilers and translators are software programs used in computer systems. They are responsible for converting high-level programming languages into machine code that can be understood and executed by the computer's hardware. These programs play a crucial role in the development and execution of software applications. Therefore, the correct answer is software.

    What hardware was used by first generation computer ?

    • CLSI

    • IC

    • Valves

    • Transistors

    • None of these

    Correct Answer
    A. Valves
    Explanation
    The correct answer is "Valves." The first generation computers, also known as vacuum tube computers, used valves as their primary hardware component. Valves were large, fragile, and consumed a lot of power. They functioned as electronic switches, allowing the flow of electricity to be controlled and creating the binary logic necessary for computing. However, valves were eventually replaced by transistors in later generations of computers due to their size, power consumption, and reliability issues.

    A hard Copy would be prepared on a  ?

    • Plotter

    • Line Printer

    • Dot Matrix Printer

    • Type writer Terminal

    • All of the above

    Correct Answer
    A. Dot Matrix Printer
    Explanation
    A dot matrix printer would be used to prepare a hard copy. Dot matrix printers use a series of small pins to strike an ink ribbon, creating dots on the paper to form characters and images. This type of printer is commonly used for printing documents that require multiple copies, such as invoices or receipts. It is a reliable and cost-effective option for producing hard copies.

    • Different Engine

    • Electronic Coputer

    • None of the Above

    Correct Answer
    A. Different Engine
    Explanation
    Charles Babbage is known for his invention of the Difference Engine, not the Different Engine. The Difference Engine was a mechanical calculator designed to automatically calculate and print mathematical tables. Babbage's invention laid the foundation for modern computers and is considered a precursor to the electronic computer. Therefore, the correct answer is "None of the Above" as none of the options listed accurately describe Charles Babbage's invention.

    Which of the following is a secondary device ?

    • ALU

    • CD

    • Keyboard

    • Printer

    • Mouse

    Correct Answer
    A. Printer
    Explanation
    A printer is considered a secondary device because it is not directly involved in the processing of data. It is used to produce hard copies of documents or images that have been processed by the computer. Unlike primary devices such as the ALU (Arithmetic Logic Unit) which performs calculations and the keyboard and mouse which input data, the printer is used for outputting data. Therefore, it is categorized as a secondary device.
