Practice

1. Which industry uses computing mainly to keep patient records and manage appointments?

easy

A. Healthcare

B. Banking

C. Agriculture

D. Retail

Solution

1. Step 1: Identify the industry related to patient care

   Healthcare is the industry focused on patient health and medical services.

2. Step 2: Match computing use to patient records and appointments

   Hospitals and clinics use computing to store patient records and schedule appointments efficiently.

3. Final Answer:

   Healthcare -> Option A

4. Quick Check:

   Patient records = Healthcare [OK]

Hint: Think where patient info is stored digitally [OK]

Common Mistakes:

• Confusing banking with healthcare
• Choosing retail for patient records
• Mixing agriculture with medical tasks

2. Which of the following is the correct way to describe computing use in retail?

easy

A. Computers analyze patient health data

B. Computers help farmers track crop growth

C. Computers manage sales and inventory

D. Computers process bank transactions

Solution

1. Step 1: Understand retail computing tasks

   Retail stores use computers to track sales and manage stock levels.

2. Step 2: Match options to retail tasks

   Computers manage sales and inventory correctly states managing sales and inventory, which fits retail.

3. Final Answer:

   Computers manage sales and inventory -> Option C

4. Quick Check:

   Retail = Sales and inventory [OK]

Hint: Retail = sales + stock management [OK]

Common Mistakes:

• Choosing farming tasks for retail
• Mixing healthcare tasks with retail
• Confusing banking with retail

3. Look at this example: A farm uses sensors connected to computers to monitor soil moisture and weather. What is the main benefit of this computing use?

medium

A. Faster patient diagnosis

B. Better crop growth and water use

C. Quicker bank loan approvals

D. Improved store checkout speed

Solution

1. Step 1: Identify the industry from the example

   The example describes a farm using sensors and computers, so it's agriculture.

2. Step 2: Understand the benefit of monitoring soil moisture and weather

   This helps farmers water crops properly and improve growth, saving resources.

3. Final Answer:

   Better crop growth and water use -> Option B

4. Quick Check:

   Agriculture + sensors = better crops [OK]

Hint: Sensors + soil = better farming [OK]

Common Mistakes:

• Picking retail improvements

4. A bank uses a computer program to approve loans automatically. The program crashes when a customer's income is missing. What is the likely error?

medium

A. The program does not handle missing data properly

B. The program is designed for farming data

C. The program uses wrong patient records

D. The program is missing sales data

Solution

1. Step 1: Understand the program's purpose and error

   The program approves loans but crashes if income data is missing, indicating a data handling issue.

2. Step 2: Identify the cause of the crash

   Missing income means the program lacks checks for empty or null values, causing failure.

3. Final Answer:

   The program does not handle missing data properly -> Option A

4. Quick Check:

   Missing data crash = no error handling [OK]

Hint: Check for missing data handling in code [OK]

Common Mistakes:

• Confusing farming or healthcare data
• Ignoring missing data causes
• Assuming wrong data type errors
