Test: Hardware and Software work together - Year 3 MCQ

Computer software consists of programs and applications that instruct the hardware on how to perform specific tasks. Without software, the hardware would not know how to operate, making software essential for the functionality of computers. This includes operating systems that manage resources and applications that perform tasks.

A barcode reader is an automatic input device that scans barcodes to retrieve information without needing direct human intervention. This technology is widely used in retail and inventory management to streamline data entry.

Systems software is responsible for managing hardware and system resources, ensuring that the computer operates efficiently and providing a platform for application software to run.

A microphone is a manual input device that requires human intervention to capture audio and convert it into digital signals for processing. Users must speak into the microphone for it to function effectively.

If a computer's hard drive fails, it must be replaced to restore functionality. The hard drive is crucial for storing data and software, and without it, the computer cannot operate correctly.

The key difference is that manual input devices require human intervention to operate, while automatic input devices function independently to collect and input data, enhancing efficiency in various applications.

Hardware requires software to function as it is the software that instructs the hardware on what tasks to perform. Without software, hardware cannot operate effectively.

Application software is created for end-users to perform specific tasks, such as word processing or spreadsheet management, allowing individuals to accomplish various functions on their computers.

Software functionality can be primarily affected by bugs in the code or by viruses, which can corrupt or disrupt normal operations. Regular updates and maintenance are essential to mitigate these issues.

Random Access Memory (RAM) is a physical component of a computer system, classified as hardware. Unlike software, which consists of programs and applications, hardware includes the tangible parts of a computer that can be touched and seen.

Hardware components can fail and require physical replacement, while software can often be reinstalled to resolve issues. This key difference highlights the functional roles of both in a computing environment.

The CPU (Central Processing Unit) is responsible for processing instructions from both the operating system and application software, making it the core component that enables a computer to perform tasks.

Utility software is designed to help maintain and optimize computer performance. Examples include antivirus programs and disk management tools, which ensure the system runs efficiently and securely.

Input devices are designed to allow users to enter data into a computer system. This includes devices like keyboards and mice, which enable interaction with the computer’s interface.

Hardware components, such as keyboards, can malfunction over time due to physical wear and tear, which may cause certain keys to stop functioning. Regular use can lead to degradation of these physical devices.
