💡 Hint

Common Mistakes

Mixing wired and wireless connections incorrectly.

Confusing Ethernet with Wi-Fi for internet.

Keyboards connect via USB, monitors via HDMI, and internet connectivity is often wireless via Wi-Fi.

Practice

1. Which port is commonly used to connect a keyboard or mouse to a computer?

easy

A. Ethernet port

B. HDMI port

C. USB port

D. Audio jack

Solution

1. Step 1: Understand common device connections

   Keyboards and mice usually connect via USB ports because they transfer data and power.

2. Step 2: Identify port functions

   HDMI is for video/audio, Ethernet for network, and audio jack for sound, so they are not used for keyboards/mice.

3. Final Answer:

   USB port -> Option C

4. Quick Check:

   Keyboard/mouse connection = USB port [OK]

Hint: Keyboards/mice use USB, not video or network ports [OK]

Common Mistakes:

• Confusing HDMI as a data port for input devices
• Thinking Ethernet connects keyboards
• Assuming audio jack transfers data

2. Which of the following is the correct way to describe HDMI?

easy

A. A port for high-definition video and audio

B. A port used only for charging devices

C. A type of USB connector

D. A wireless connection for internet

Solution

1. Step 1: Recall HDMI purpose

   HDMI stands for High-Definition Multimedia Interface and is used to send video and audio signals.

2. Step 2: Eliminate incorrect options

   It is not a wireless connection, not used only for charging devices, and not a type of USB connector.

3. Final Answer:

   A port for high-definition video and audio -> Option A

4. Quick Check:

   HDMI = video/audio port [OK]

Hint: HDMI always relates to video and audio, not wireless or charging [OK]

Common Mistakes:

• Thinking HDMI is wireless
• Confusing HDMI with USB
• Assuming HDMI charges devices

3. You want to connect your laptop to the internet without cables. Which option correctly describes how to do this?

easy

A. Connect via Wi-Fi to the wireless network

B. Use a USB cable to connect to the router

C. Plug an HDMI cable into the laptop

D. Use an Ethernet cable to connect to the monitor

Solution

1. Step 1: Understand wireless internet connection

   Wi-Fi allows devices to connect to the internet without cables.

2. Step 2: Evaluate options for internet connection

   USB and Ethernet cables require wires; HDMI connects video, not internet; only Wi-Fi is wireless internet.

3. Final Answer:

   Connect via Wi-Fi to the wireless network -> Option A

4. Quick Check:

   Wireless internet = Wi-Fi connection [OK]

Hint: Wireless internet means Wi-Fi, not cables [OK]

Common Mistakes:

• Confusing HDMI with internet connection
• Thinking USB cable provides wireless internet
• Using Ethernet to connect to monitor for internet

4. A laptop is connected to a monitor using an HDMI cable. What will happen if the HDMI cable is unplugged while the laptop is on?

medium

A. The laptop will shut down immediately

B. The laptop will start charging

C. The laptop will lose internet connection

D. The monitor will stop displaying the laptop screen

Solution

1. Step 1: Understand HDMI cable role

   HDMI carries video and audio signals from laptop to monitor.

2. Step 2: Predict effect of unplugging HDMI

   Removing HDMI stops video signal, so monitor shows no laptop screen. Laptop stays on and internet is unaffected.

3. Final Answer:

   The monitor will stop displaying the laptop screen -> Option D

4. Quick Check:

   Unplug HDMI = no video on monitor [OK]

Hint: HDMI unplugged means no video on monitor, laptop stays on [OK]

Common Mistakes:

• Thinking laptop shuts down
• Assuming internet disconnects
• Believing laptop starts charging

5. A user tries to connect a USB device but it is not recognized by the computer. Which of the following is the most likely cause?

medium

A. The HDMI cable is unplugged

B. The USB port is damaged or not working

C. The Wi-Fi signal is weak

D. The monitor is turned off

Solution

1. Step 1: Identify the problem context

   The USB device is not recognized, so the issue relates to USB connection.

2. Step 2: Analyze options

   Damaged USB port can cause this. HDMI cable, Wi-Fi, or monitor status do not affect USB device recognition.

3. Final Answer:

   The USB port is damaged or not working -> Option B

4. Quick Check:

   USB device not recognized = USB port issue [OK]

Hint: USB device issues usually mean USB port problems [OK]

Common Mistakes:

• Blaming HDMI cable for USB device issues
• Thinking Wi-Fi affects USB recognition
• Assuming monitor power affects USB devices
