Chapter 3 Hardware

What is the primary function of input devices in a computer system?

• To process data

• To store data

• To enter data into the computer

• To display data

Which of the following is an example of secondary storage?

• RAM

• CPU

• Hard Disk Drive

• Power Supply

Which of the following is a benefit of using embedded systems?

• High power consumption

• Large size

• Increased complexity

• Specific functionality

How does a laser printer primarily operate?

• By engraving the text on the paper with a laser

• By spraying ink directly onto paper

• By using a laser beam to transfer toner to paper

• By heating up and melting wax onto paper

What is the main purpose of a buffer in computer systems?

• To increase processing speed

• To store temporary data during data transfer

• To enhance graphics quality

• To reduce power consumption

Which of the following statements correctly describes RAM?

• Non-volatile and used for permanent storage

• Volatile and used for temporary storage

• Non-volatile and used for temporary storage

• Volatile and used for permanent storage

What is a key difference between Static RAM (SRAM) and Dynamic RAM (DRAM)?

• SRAM is slower than DRAM

• DRAM is more expensive than SRAM

• SRAM needs to be refreshed periodically

• DRAM needs to be refreshed periodically

Why might a device use Static RAM (SRAM) instead of Dynamic RAM (DRAM)?

• For lower cost

• For higher speed

• For larger storage capacity

• For lower power consumption

What distinguishes Programmable ROM (PROM) from EPROM and EEPROM?

• It is written once and cannot be erased

• It can be erased using ultraviolet light

• It can be erased electrically

In what type of systems is monitoring and control most commonly used?

• Video gaming systems

• Home heating systems

• Word processing software

• Email servers
