6.1 Hardware and software

• What does the term "hardware" refer to in computer systems?

  Physical components
• The Central Processing Unit (CPU) is an example of a hardware component
• Match the type of software with its example:

  System software ↔️ Operating system

  Application software ↔️ Web browser
• Hardware consists of tangible, physical components
• What is the function of hardware in a computer system?

  Executes instructions
• The CPU has multiple cores and cache memory.
• RAM is volatile, meaning data is lost when power is turned off.
• Order the following hardware components from fastest to slowest access speeds:

  1️⃣ RAM

  2️⃣ SSD

  3️⃣ HDD
• What is the primary role of the CPU in a computer system?

  Executes instructions
• RAM has a high storage capacity and is non-volatile.

  False
• The speed of data access in storage determines its impact on system performance
• What feature of the CPU determines its overall processing speed?

  Clock speed
• Match the input device with its function:

  Keyboard ↔️ Data entry

  Microphone ↔️ Audio input
• Storage devices like HDDs and SSDs are non-volatile.
• Output devices provide feedback to users through visual, auditory, or physical output
• What is an example of system software in a computer system?

  Operating system
• Hardware and software must work together to perform tasks in a computer system.
• Hardware is tangible, while software is intangible
• What is the brain of the computer that executes instructions called?

  Central Processing Unit
• Storage devices such as HDDs and SSDs provide temporary data storage.

  False
• The CPU's clock speed is measured in Hertz
• What type of memory stores active data and instructions for the CPU?

  Random Access Memory
• The number of cores in a CPU affects its overall processing speed.
• Persistent storage devices like HDDs and SSDs are non-volatile
• Match the input device with its purpose:

  Mouse ↔️ Cursor control

  Keyboard ↔️ Text input
• What is the primary purpose of storage devices like HDDs and SSDs?

  Persistent data storage
• RAM enables efficient multitasking due to its high speed and limited capacity.
• The two main types of software are system software and application software
• Match the type of software with its definition:

  System software ↔️ Manages computer hardware

  Application software ↔️ Performs specific tasks
• What does system software manage and control in a computer system?

  Hardware
• Application software is designed for users to perform specific tasks
• System software ensures the computer functions correctly, while application software allows users to accomplish specific tasks.
• Match the type of software with its definition:

  System software ↔️ Manages hardware

  Application software ↔️ Performs user tasks
• What is the purpose of application software in a computer system?

  Specific user tasks
• Hardware refers to the physical components of a computer system that you can touch
• What are examples of software in a computer system?

  Operating systems, applications
• Hardware and software must work together for a computer to function.
• Match the hardware component with its function:

  CPU ↔️ Executes instructions

  RAM ↔️ Temporary storage

  HDD/SSD ↔️ Permanent storage

  Input devices ↔️ Allows data entry

  Output devices ↔️ Displays data
• What is the key feature of the CPU that impacts overall processing speed?

  Clock speed
• RAM is a type of memory that provides fast access but is volatile
