3.2a Wired & Wireless Networks

What type of connection uses physical cables?

• Ethernet

• WiFi

• Satellite

• Bluetooth

Answer explanation

Ethernet is the type of connection that uses physical cables for data transmission.

What device is essential for creating a local wireless network?

• Switch

• Router

• Firewall

• Hub

Answer explanation

A router is essential for creating a local wireless network as it connects multiple devices and routes data between them. It also provides wireless access to the network.

What can affect the speed of a wireless connection?

• Type of cable used

• Distance from router

• Ethernet protocol

• Type of NIC

Answer explanation

Distance from router can affect the speed of a wireless connection due to signal strength degradation over longer distances.

Which connection type generally offers more security?

• Infrared

• Wired

• Bluetooth

• Wireless

Answer explanation

Wired connections generally offer more security than wireless options due to the physical nature of the connection, making it harder for unauthorized access.

What is a common protocol used in wired connections?

• Ethernet

• TCP/IP

• HTTP

• FTP

Answer explanation

Ethernet is a common protocol used in wired connections, providing a standard way for devices to communicate over a network.

What is required to connect to a wired network?

• Router

• WNIC

• NIC

• Access Point

Answer explanation

To connect to a wired network, a NIC (Network Interface Card) is required to establish a physical connection between the device and the network.

Which of the following is a disadvantage of wireless connections?

• Faster speed

• More secure

• Freedom of movement

• Slower speed

Answer explanation

The correct choice is 'Slower speed' because one of the disadvantages of wireless connections is that they can be slower compared to wired connections.

Which material is primarily used in the manufacturing of cables for internet connectivity?

• Aluminum

• Copper

• Silicon

• Gold

Answer explanation

Copper is primarily used in the manufacturing of cables for internet connectivity due to its excellent conductivity and durability.

Which connection type allows for greater freedom of movement?

• Wired

• Fibre optic

• Wireless

• Ethernet

Answer explanation

The correct choice is Wireless because it allows for greater freedom of movement compared to wired, fibre optic, and Ethernet connections.

What can interfere with wireless network connections?

• Fibre optic cables

• USB cables

• Obstacles like walls

• Ethernet cables

Answer explanation

Obstacles like walls can interfere with wireless network connections by blocking or weakening the signal strength, leading to poor connectivity.
