Understanding Tech Devices and Functions

In a computer lab, Mustapha is curious about the primary function of a CPU. He asks his classmates, 'What does the CPU do?'

• To execute instructions from computer programs.

• To store data permanently.

• To manage network connections.

• To provide power to the computer.

During a technology class, Arnau and Luka were discussing how an SSD differs from an HDD in terms of performance.

• HDDs provide better performance in random data access than SSDs.

• SSDs offer significantly better performance than HDDs due to faster data access speeds and no moving parts.

• HDDs are faster than SSDs due to their spinning disks.

• SSDs have moving parts that slow down performance.

During a group project, Arnau and Hugo were discussing the importance of RAM in their computers. Arnau mentioned that RAM acts as the short-term memory of a computer, facilitating quick access to data for active processes. Hugo, however, thought that RAM was responsible for processing graphics and images. What role does RAM actually play in a computer system?

• RAM controls the power supply to the computer.

• RAM stores data permanently for long-term use.

• RAM is responsible for processing graphics and images.

• RAM acts as the short-term memory of a computer, facilitating quick access to data for active processes.

In a school, Leo is trying to understand the functions of a router and a switch while working on a group project with Joaquín and Manuel.

• Routers manage traffic within a single network; switches route data between multiple networks.

• Routers are used for wireless connections; switches are used for wired connections.

• Routers connect devices within the same network; switches connect different networks.

• Routers connect different networks; switches connect devices within the same network.

Luka is building a new gaming PC and is considering which component is essential for enhancing his gaming experience. What is the main purpose of a graphics card?

• To render images and videos for display.

• To store large amounts of data.

• To increase internet speed.

• To manage system memory.

How do smartphones and tablets differ in terms of user interface, as experienced by Jose and Luka while using their devices for school projects?

• Smartphones and tablets have identical user interfaces with no differences.

• Smartphones have a compact, one-handed interface; tablets have a larger, multi-window interface.

• Smartphones have a larger, multi-window interface; tablets have a compact, one-handed interface.

• Tablets are designed for voice commands only, while smartphones use touch gestures.

During a group project, Diego and Alejandro were discussing the role of a motherboard in a computer. They wondered, what is the function of a motherboard in a computer?

• To store data permanently in a computer.

• To manage the operating system's user interface.

• The function of a motherboard in a computer is to connect and allow communication between all hardware components.

• To provide power to the CPU only.

During a school event, Manuel and Luis were discussing the difference between active and passive speakers.

• Active speakers have built-in amplifiers; passive speakers require external amplifiers.

• Active speakers are larger than passive speakers.

• Passive speakers have built-in amplifiers; active speakers do not.

• Active speakers are used for outdoor events, while passive speakers are for indoor use.

During a science project, Leo and his friends are discussing the role of a power supply unit in their electronic circuit. What is the primary function of a power supply unit?

• To regulate the temperature of electronic devices.

• To store electrical energy for later use.

• To amplify electrical signals for better transmission.

• To convert electrical power to usable power for electronic devices.

Mustapha and Vladislav are discussing how laser printers and inkjet printers differ in operation. Can you help them understand the differences?

• Laser printers use liquid ink and spray technology, while inkjet printers use laser technology and toner.

• Inkjet printers are faster than laser printers and use toner cartridges.

• Laser printers are more affordable than inkjet printers and use liquid ink.

• Laser printers use laser technology and toner, while inkjet printers use liquid ink and spray technology.
