💡 Hint

Common Mistakes

Selecting 'ignore' which does not describe network functions.

Networks connect devices to share messages and access resources like files and printers.

Practice

1. Why do computer networks enable communication between devices?

easy

A. Because they make devices physically larger

B. Because they increase the speed of individual devices

C. Because they replace the need for software applications

D. Because they connect devices allowing data exchange

Solution

1. Step 1: Understand the role of networks

   Networks link devices so they can send and receive information.

2. Step 2: Identify how communication happens

   By connecting devices, networks allow data to move between them easily.

3. Final Answer:

   Because they connect devices allowing data exchange -> Option D

4. Quick Check:

   Networks connect devices = communication enabled [OK]

Hint: Networks connect devices to share data easily [OK]

Common Mistakes:

• Thinking networks speed up devices individually
• Confusing networks with software functions
• Believing networks change device size

2. Which of the following is the correct way to describe a network's function?

easy

A. Networks store all data locally on each device

B. Networks allow devices to share resources like printers

C. Networks prevent devices from communicating

D. Networks make devices work without electricity

Solution

1. Step 1: Review network functions

   Networks enable devices to share resources such as printers and files.

2. Step 2: Eliminate incorrect options

   Networks do not store data locally on each device, prevent communication, or supply power.

3. Final Answer:

   Networks allow devices to share resources like printers -> Option B

4. Quick Check:

   Resource sharing = networks enable it [OK]

Hint: Networks share resources like printers and files [OK]

Common Mistakes:

• Thinking networks store data only locally
• Believing networks block communication
• Assuming networks provide power to devices

3. Consider this scenario: A home network connects a laptop, a smartphone, and a printer. Which of the following is true?

medium

A. The smartphone can print documents using the printer over the network

B. The printer can send emails to the laptop directly

C. The laptop cannot access the internet through the network

D. Devices on the network cannot share files

Solution

1. Step 1: Understand device roles in a home network

   Devices connected in a network can share resources like printers and internet.

2. Step 2: Analyze each option

   The smartphone can use the printer via the network; printers do not send emails; laptops usually access internet through networks; file sharing is possible.

3. Final Answer:

   The smartphone can print documents using the printer over the network -> Option A

4. Quick Check:

   Network resource sharing = smartphone prints [OK]

Hint: Devices on a network share printers and internet [OK]

Common Mistakes:

• Assuming printers send emails
• Thinking laptops can't access internet via network
• Believing file sharing is impossible on networks

4. A small office network is not allowing employees to share files. What is the most likely cause?

medium

A. The network cables are unplugged

B. The printer is turned off

C. File sharing is disabled on the devices

D. The internet connection is slow

Solution

1. Step 1: Identify the problem context

   Employees cannot share files, which depends on device settings and network connection.

2. Step 2: Evaluate each option's impact

   Unplugged cables stop all network communication; file sharing disabled stops file access; printer off does not affect file sharing; slow internet affects speed but not local sharing.

3. Final Answer:

   File sharing is disabled on the devices -> Option C

4. Quick Check:

   File sharing disabled = no file sharing [OK]

Hint: Check if file sharing is enabled on devices first [OK]

Common Mistakes:

• Blaming printer status for file sharing issues
• Assuming slow internet stops local file sharing
• Ignoring device settings for sharing

5. In a company, employees need to access a shared database and print documents from different floors. How does the network enable this?

hard

A. By connecting all computers and printers to a central network allowing resource sharing

B. By installing the same software on every device without connecting them

C. By using separate internet connections for each floor

D. By physically moving files using USB drives only

Solution

1. Step 1: Understand network resource sharing in a company

   Networks connect devices so they can share resources like databases and printers across locations.

2. Step 2: Compare options for enabling access

   Connecting devices to a central network allows shared access; installing software alone doesn't connect devices; separate internet connections don't share resources; USB drives are manual and inefficient.

3. Final Answer:

   By connecting all computers and printers to a central network allowing resource sharing -> Option A

4. Quick Check:

   Central network connection = shared access [OK]

Hint: Central network connects devices for shared access [OK]

Common Mistakes:

• Thinking software alone shares resources
• Assuming separate internet connections share files
• Relying only on USB drives for sharing
