Practice

1. Why is mobile computing considered dominant in today's technology world?

easy

A. Because it allows people to use devices anywhere and anytime

B. Because it requires large, stationary computers

C. Because it only works with wired connections

D. Because it limits users to specific locations

Solution

1. Step 1: Understand the meaning of mobile computing

   Mobile computing means using technology on portable devices with wireless connections.

2. Step 2: Identify why it is dominant

   It is dominant because it allows users freedom to work anywhere and anytime, unlike stationary computers.

3. Final Answer:

   Because it allows people to use devices anywhere and anytime -> Option A

4. Quick Check:

   Mobile computing = freedom to use anywhere [OK]

Hint: Mobile means portable and wireless use anytime, anywhere [OK]

Common Mistakes:

• Thinking mobile computing needs wired connections
• Believing it restricts users to fixed locations
• Confusing mobile computing with desktop computing

2. Which of the following is the correct description of mobile computing?

easy

A. Using devices that cannot connect to the internet

B. Using desktop computers connected by cables

C. Using devices only in offices with wired internet

D. Using portable devices connected wirelessly to access data

Solution

1. Step 1: Identify key features of mobile computing

   Mobile computing involves portable devices and wireless connections.

2. Step 2: Match the correct description

   Using portable devices connected wirelessly to access data correctly describes portable devices with wireless access, unlike other options.

3. Final Answer:

   Using portable devices connected wirelessly to access data -> Option D

4. Quick Check:

   Portable + wireless = mobile computing [OK]

Hint: Mobile means portable devices + wireless connection [OK]

Common Mistakes:

• Choosing wired or desktop-only options
• Ignoring the wireless aspect
• Confusing mobile computing with offline devices

3. Look at this flowchart describing mobile computing usage:



What is the main reason this flowchart shows mobile computing as dominant?

medium

A. It shows users limited to one location

B. It shows wireless connection enabling access anywhere

C. It shows devices needing cables to connect

D. It shows users only accessing offline data

Solution

1. Step 1: Analyze the flowchart elements

   The flowchart shows a user with a mobile device connecting wirelessly to cloud services from any location.

2. Step 2: Understand why this shows dominance

   Wireless access anywhere allows freedom and convenience, making mobile computing dominant.

3. Final Answer:

   It shows wireless connection enabling access anywhere -> Option B

4. Quick Check:

   Wireless + anywhere access = mobile computing dominance [OK]

Hint: Wireless access anywhere means mobile computing wins [OK]

Common Mistakes:

• Ignoring wireless connection in the flowchart
• Thinking devices need cables
• Assuming offline access only

4. This code snippet tries to describe mobile computing features:

device = "mobile"
connection = "wired"
if device == "mobile" and connection == "wireless":
    print("Mobile computing active")
else:
    print("Not mobile computing")

What is the error and how to fix it?

medium

A. The connection should be 'wireless' to activate mobile computing

B. The device should be 'desktop' for mobile computing

C. The print statements are reversed

D. No error, code is correct

Solution

1. Step 1: Check variable values and condition

   The device is 'mobile' but connection is 'wired', while condition checks for 'wireless'.

2. Step 2: Fix the connection value

   Change connection to 'wireless' to meet the condition and print 'Mobile computing active'.

3. Final Answer:

   The connection should be 'wireless' to activate mobile computing -> Option A

4. Quick Check:

   Mobile + wireless = active mobile computing [OK]

Hint: Mobile needs wireless connection to be active [OK]

Common Mistakes:

• Not matching connection string exactly
• Thinking device type is wrong
• Ignoring the condition logic

5. A company wants to improve employee productivity by adopting mobile computing. Which combination best explains why mobile computing will help?
