Computer Hardware Review Questions

True/False Questions

• False: Flash memory is a type of non-volatile memory. Volatile memory loses its contents when power is removed, whereas non-volatile memory retains its contents.
• True: Volatile memory loses its contents when power is removed. This is a key characteristic that distinguishes it from non-volatile memory.
• True: In an 8-bit coding scheme, 8 bits can represent one character. This is a common standard, often associated with ASCII encoding.
• True: In general, a high-powered processor is not necessary for a computer that will be used primarily to check email and browse the web. These tasks are not computationally intensive.
• False: Plotters are not small, lightweight printers that easily can be connected to mobile devices. Plotters are specialized printers used for producing high-quality graphics and are typically larger and more complex than standard printers.
• False: The speed at which data travels on a bus is not referred to as the word size. The speed is generally referred to as the bus speed or bus clock rate. Word size refers to the number of bits a processor can handle simultaneously.
• True: Uninterruptible power supplies (UPS) and surge suppressors will help protect your computer from power outages and voltage spikes. UPS provides temporary power, while surge suppressors protect against voltage fluctuations.

Multiple Choice Questions

• Cloud storage: Cloud storage requires an Internet connection to access and store data. Internal hard drives, solid-state drives, and flash memory do not inherently require an Internet connection.
• Desktop computer: In a desktop computer, the system unit is in a separate housing from the monitor. All-in-one computers integrate the system unit and monitor into a single device. Laptop and tablet computers also integrate these components.
• Touchpointer: A touchpointer is not typically considered a pointing device in the same category as trackballs, touchpads, and mice. The latter are specifically designed for cursor control.
• Device driver: A device driver tells your computer how to connect to devices. It acts as an interface between the operating system and the hardware.

Troubleshooting

• Check to see that all cables are properly connected: If experiencing display problems, the first troubleshooting step should be to check cable connections. This is the simplest and least invasive approach. Other options, like contacting a professional or buying a new monitor, are more drastic and should be considered after basic checks have been performed.

Repair Scenarios

• Screen is broken: Likely requiring professional assistance. Replacing a screen often involves specialized tools and expertise.
