Questions


1. Describe what is meant by information systems hardware. Information systems hardware refers to the physical components of a computer system that enable data processing and storage. This includes devices such as the CPU, memory modules, storage devices, input and output devices, and networking hardware. These tangible components work together to facilitate the execution of software applications and manage data flow within an information system.


2. What has led to the shift toward mobility in computing? The shift toward mobility in computing has been driven by advancements in wireless technology, miniaturization of devices, and the proliferation of smartphones and tablets. The desire for constant connectivity, portability, and access to information from anywhere has pushed manufacturers to develop lightweight, wireless devices that support remote access, cloud computing, and mobile applications, transforming how users interact with technology.


3. What is the impact of Moore’s Law on hardware components? Moore’s Law, which predicts the doubling of transistors on a microchip approximately every two years, has significantly impacted hardware by enabling continual improvements in processing speed, capacity, and energy efficiency. This exponential growth has led to smaller, faster, and more affordable processors, RAM modules, and storage devices, fundamentally transforming the capabilities and affordability of computing hardware.


4. Summarize one item linked to in the “Integrated Computing” section. (Summary of a linked item, e.g., integrated circuits). Integrated circuits (ICs), also known as microchips, are compact assemblies of numerous electronic components such as transistors, resistors, and capacitors embedded onto a small semiconductor substrate. They revolutionized electronic device design by enabling the miniaturization of complex circuits, leading to faster, more reliable, and energy-efficient hardware essential for modern computing systems.


5. Why is the personal computer now considered a commodity? The personal computer is now considered a commodity because it is widely produced and available at a standardized quality and price point, with minimal differentiation between brands. Mass production, technological convergence, and economies of scale have made PCs accessible and interchangeable, much like other everyday goods.


6. The CPU can also be thought of as the _____________ of the computer. brain


7. List the units of measure for data storage in increasing order from smallest to largest, kilobyte to yottabyte. byte, kilobyte, megabyte, gigabyte, terabyte, petabyte, exabyte, zettabyte, yottabyte


8. What is the bus of a computer? The bus of a computer is a communication pathway that transmits data between different components like the CPU, memory, and peripherals.


9. Name two differences between RAM and a hard disk. RAM is volatile, temporary memory that provides fast access for active processes, whereas a hard disk is non-volatile, permanent storage. RAM is faster but more expensive per unit, while hard disks have larger storage capacity at lower cost.


10. What are the advantages of solid-state drives over hard disks? Solid-state drives (SSDs) offer faster data access speeds, lower power consumption, greater durability (no moving parts), and quieter operation compared to traditional hard disks.
