Understanding the Information Processing Cycle

What is the primary function of input devices?

• To allow users to input data and control signals into a computer.

• To manage the computer's power supply.

• To display output from the computer to the user.

• To store data permanently in the computer.

Name three common input devices used in computers.

• Projector

• Keyboard, Mouse, Scanner

• Monitor

• Printer

What role do output devices play in the information processing cycle?

• Output devices display or present the results of data processing.

• Output devices process data before it is sent to storage.

• Output devices store data for future use.

• Output devices input data into the system.

List two examples of output devices.

• Scanner

• Speaker

• Monitor, Printer

• Keyboard

What is the purpose of storage devices in a computer system?

• To manage the power supply of the computer.

• To increase the processing speed of the CPU.

• The purpose of storage devices is to store data and programs in a computer system.

• To connect peripheral devices to the system.

Identify three types of storage devices.

• Floppy Disk

• CD-ROM

• Tape Drive

• Hard Disk Drive, Solid State Drive, USB Flash Drive

What is the function of the processing unit in a computer?

• To manage network connections

• The function of the processing unit in a computer is to execute instructions and process data.

• To store data permanently

• To provide power to the computer

Explain the difference between the CPU and GPU.

• The CPU is for general-purpose tasks with few powerful cores, while the GPU is for parallel processing with many less powerful cores.

• The CPU is used exclusively for gaming, while the GPU is used for office applications.

• The CPU has many cores for parallel processing, while the GPU has a single powerful core.

• The CPU is designed for graphics rendering, while the GPU handles general computing tasks.

How does data flow through the information processing cycle?

• Data flows through input, processing, output, storage, and feedback.

• Data flows only through input and output.

• Data is processed before being input.

• Data is stored before any processing occurs.

Describe the characteristics of solid-state drives (SSDs).

• Higher power consumption than traditional drives

• Characteristics of SSDs include faster data access speeds, durability due to no moving parts, lower power consumption, lightweight design, and compact size.

• Heavier design with multiple moving parts

• Higher data access speeds than HDDs
