    The contents of these chips are lost when the computer is switched off?

    • ROM chips

    • RAM chips

    • DRAM chips

    Correct Answer
    A. RAM chips
    Explanation
    RAM stands for Random Access Memory, which is a type of computer memory that is volatile, meaning its contents are lost when the computer is switched off. This is in contrast to ROM (Read-Only Memory) chips, which retain their contents even when the power is turned off. DRAM (Dynamic Random Access Memory) chips are a specific type of RAM that also lose their contents when the power is switched off. Therefore, the correct answer is RAM chips.

    Which parts of the computer perform arithmetic calculations?

    • ALU

    • Registers

    • Logic bus

    Correct Answer
    A. ALU
    Explanation
    The ALU, or Arithmetic Logic Unit, is the part of a computer that performs arithmetic calculations. It is responsible for executing mathematical operations such as addition, subtraction, multiplication, and division. The ALU is a critical component of the CPU (Central Processing Unit) and is designed to handle numerical computations efficiently and accurately. In contrast, registers are small storage units within the CPU that temporarily hold data during processing, while the logic bus is a communication pathway that transfers data between different components of the computer. Therefore, the ALU is the correct answer as it specifically handles arithmetic calculations.

    What are responsible for storing permanent data and instructions?

    • RAM chips

    • ROM chips

    • DRAM chips

    Correct Answer
    A. ROM chips
    Explanation
    ROM chips are responsible for storing permanent data and instructions. Unlike RAM chips, which are volatile and lose their data when the power is turned off, ROM chips retain their data even when the power is off. This makes them ideal for storing important data and instructions that need to be permanently stored and accessed by the computer. DRAM chips, on the other hand, are a type of volatile memory used for temporary storage and quick access to data during computer operations.

    Which bus controls the sequencing of reading/write operations.

    • Data bus

    • Address bus

    • Control bus

    Correct Answer
    A. Control bus
    Explanation
    The control bus is responsible for controlling the sequencing of reading/write operations. It carries control signals that instruct the various components of a computer system to perform specific tasks, such as initiating memory read or write operations. The control bus ensures that these operations are executed in the correct order and at the appropriate times, coordinating the flow of data between the CPU, memory, and other peripherals.

    All activities on the computer are directed by the?

    • Arithmetic Logic Unit

    • Data Bus

    • Control Unit

    • Main store

    Correct Answer
    A. Control Unit
    Explanation
    The control unit is responsible for directing and coordinating all activities on the computer. It fetches instructions from the memory, decodes them, and then executes them by sending signals to other components of the computer such as the arithmetic logic unit and data bus. Without the control unit, the computer would not be able to perform any operations or execute any instructions.

    What type of computer chips are said to be volatile?

    • RAM chips

    • ROM chips

    • DRAM

    Correct Answer
    A. RAM chips
    Explanation
    RAM chips are said to be volatile because they require constant power to retain the data stored in them. Volatile memory means that the data is lost when the power is turned off or interrupted. RAM (Random Access Memory) is a type of volatile memory where data can be read from and written to quickly, making it ideal for temporary storage and running programs. In contrast, ROM (Read-Only Memory) chips contain non-volatile memory that retains data even when the power is turned off, and DRAM (Dynamic Random Access Memory) is a specific type of RAM chip.

    You need to update some work on the computer but have deleted all your files by mistake. Luckily you have kept a printed copy. Which one of the following devices would you use to rectify this problem?

    • Camera

    • Printer

    • Scanner

    • OMR

    • Keyboard

    Correct Answer
    A. Scanner
    Explanation
    A scanner is a device that can convert physical documents or printed copies into digital files. In this scenario, since you have a printed copy of the files that you need to update on the computer, using a scanner would be the most suitable option. By scanning the printed copy, you can create a digital version of the file and then transfer it to your computer, thus rectifying the problem caused by deleting the original digital files.

    What are small high-speed memory units used for storing temporary results?

    • CPUs

    • Registers

    • Control unit

    Correct Answer
    A. Registers
    Explanation
    Registers are small high-speed memory units used for storing temporary results. They are located inside the CPU and are used to hold data that is frequently accessed or manipulated by the processor. Registers are faster to access than other types of memory, such as RAM, which makes them ideal for storing temporary data that needs to be quickly retrieved and used by the CPU.

    Rate this question:

  • 10. 

    Which port transmits only one bit at a time?

    • Serial Vs Parellel Ports

    • Usb Port

    • Serial Port

    • Parallel port

    Correct Answer
    A. Serial Port
    Explanation
    A serial port is a type of port that transmits data one bit at a time. Unlike parallel ports, which transmit multiple bits simultaneously, a serial port sends data in a sequential manner. This makes it slower compared to parallel ports but more suitable for long-distance communication and connecting devices that only require low data transfer rates. The USB port, on the other hand, can transmit multiple bits simultaneously and is commonly used for connecting various devices to a computer.
