    What does DIMM stands for?

    • Dual Interrupt Memory Module

    • Dual Inverse Memory Module

    • Dual Inline Memory Module

    • Dual Interactive Memory Module

    Correct Answer
    A. Dual Inline Memory Module
    Explanation
    DIMM stands for Dual Inline Memory Module. DIMM is a type of computer memory module that is used to store data and instructions for the CPU. It is called "dual" because it has separate electrical contacts on both sides of the module, allowing for increased data transfer rates. The term "inline" refers to the fact that the module is plugged directly into the motherboard, rather than being connected via a cable. DIMMs are commonly used in desktop and server computers to provide high-speed and efficient memory storage.

    Which device does the processor uses to interact with rest of the hardware?

    • CMOS Battery

    • Expansion slot

    • Memory slot

    • BIOS chip

    Correct Answer
    A. BIOS chip
    Explanation
    The processor uses the BIOS chip to interact with the rest of the hardware. The BIOS (Basic Input/Output System) is a firmware that is stored on the BIOS chip and is responsible for initializing and controlling the hardware components during the boot process. It provides the necessary instructions for the processor to communicate with devices such as the memory, storage, and input/output devices. Without the BIOS chip, the processor would not be able to effectively interact with the rest of the hardware.

    Which of the following computer case is generally used for Servers?

    • Mid Tower case

    • Desktop case

    • Micro Tower case

    • Full Tower case

    Correct Answer
    A. Full Tower case
    Explanation
    Full Tower case is generally used for Servers because it provides ample space for multiple hard drives, expansion cards, and cooling systems. Servers require larger cases to accommodate their high-performance components and to allow for future upgrades. Full Tower cases also offer better airflow and cable management options, which are crucial for maintaining optimal server performance and preventing overheating. Additionally, the larger size of Full Tower cases allows for better organization and accessibility of server components, making maintenance and upgrades easier.

    What is the full form of ATAPI?

    • Advanced Technology Attachment Packing Interface

    • Advanced Technology Attachment Packet Interface

    • Advanced Technology Attachment Packet Interrupt

    • Advanced Technology Attachment Packing Interrelate

    Correct Answer
    A. Advanced Technology Attachment Packet Interface
    Explanation
    ATAPI stands for Advanced Technology Attachment Packet Interface. This interface is an extension of the ATA (Advanced Technology Attachment) standard that allows for the connection of devices such as CD-ROM drives, DVD drives, and tape drives to a computer's motherboard. ATAPI enables these devices to communicate with the computer and transfer data using packets. This allows for faster and more efficient data transfer compared to the older ATA standard.

  • 7. 

    A device that translates digital signal of computers into analog signal, is known as?

    • NIC

    • Sound card

    • Modem

    • Display devices

    Correct Answer
    A. Modem
    Explanation
    A modem is a device that translates digital signals from computers into analog signals that can be transmitted over telephone lines. It allows computers to communicate with each other over long distances using existing telephone infrastructure. A modem converts the digital data into analog signals that can be transmitted through telephone lines, and then converts the analog signals back into digital data at the receiving end. This enables the transmission of data over long distances and facilitates internet connectivity.

    System Lockup Errors can be best described as:

    • System Lockup Error stop all processes and shut the system down without warning

    • System Lockup Error is an error condition that causes the system or an application to stop responding to user input

    • System Lock error occurs when an application is attempting to perform an action that Windows does not permit. Windows forces the application to close

    • System Lockup Error is an error condition that occurs when you try to start an application that is not properly installed

    Correct Answer
    A. System Lockup Error is an error condition that causes the system or an application to stop responding to user input
    Explanation
    System Lockup Errors can be best described as an error condition that causes the system or an application to stop responding to user input. This means that when a system lockup error occurs, the system or application becomes unresponsive and does not react to any commands or actions from the user. This can result in the need to forcefully shut down the system or application in order to regain control.

    Choose a DC voltage that power supply does NOT have?

    • +3.3 volts

    • +5 volts

    • -3.3 volts

    • -5 volts

    Correct Answer
    A. -3.3 volts
    Explanation
    The power supply does not have a -3.3 volts DC voltage because it only provides positive DC voltages (+3.3 volts and +5 volts) and negative DC voltages (-5 volts). Therefore, -3.3 volts is not available as an option for the DC voltage provided by the power supply.

    Port COM1 is a type of _____________________

    • Parallel Port

    • USB Port

    • Serial Port

    • PS/2 Port

    Correct Answer
    A. Serial Port
    Explanation
    A Port COM1 is a type of serial port. Serial ports are used to connect devices such as modems, printers, and mice to a computer. They transmit data one bit at a time in a sequential manner, hence the term "serial." In contrast, parallel ports transmit multiple bits simultaneously. USB ports are a different type of interface used for connecting various devices, while PS/2 ports are typically used for connecting keyboards and mice.

    Which bus does the processor uses to communicate with other peripherals?

    • Data bus

    • System bus

    • Address bus

    • Memory bus

    Correct Answer
    A. System bus
    Explanation
    The processor uses the system bus to communicate with other peripherals. The system bus is responsible for transferring data, addresses, and control signals between the processor and other components such as memory, input/output devices, and the motherboard. It acts as a communication pathway, allowing the processor to send and receive information to and from different peripherals connected to the system.

    Which one is NOT a type of bus?

    • External

    • Memory

    • Data

    • Address

    Correct Answer
    A. External
    Explanation
    The given question asks to identify the option that is not a type of bus. The options provided are External, Memory, Data, and Address. Among these options, External is not a type of bus. Buses are communication pathways that transfer data between different components of a computer system. Memory, Data, and Address are all types of buses that facilitate the transfer of specific types of information within a computer system. However, External does not pertain to a specific type of bus and is therefore the correct answer.

    What is the data transfer rate for IDE - ATA/2 PIO mode?

    • 3.3 Mbps

    • 5 Mbps

    • 8.3 Mbps

    • 1.3 Mbps

    Correct Answer
    A. 8.3 Mbps
    Explanation
    The data transfer rate for IDE - ATA/2 PIO mode is 8.3 Mbps. This mode refers to the Programmed Input/Output mode used in IDE (Integrated Drive Electronics) or ATA (Advanced Technology Attachment) devices. It allows for data transfer between the device and the computer's memory using the PIO protocol. The transfer rate of 8.3 Mbps indicates the speed at which data can be read from or written to the device in this mode.

    Which one of the following ATA standards introduced SMART?

    • ATA-1

    • ATA-2

    • ATA-3

    • ATAPI

    Correct Answer
    A. ATA-3
    Explanation
    ATA-3 is the correct answer because it was the ATA standard that introduced SMART (Self-Monitoring, Analysis, and Reporting Technology). SMART is a feature that allows hard drives to monitor their own health and report any potential issues to the user. ATA-1, ATA-2, and ATAPI are not associated with the introduction of SMART.
