Network Hardware

What is the primary function of a firewall in a network?

• To convert digital data into analog signals

• To monitor and control network traffic based on protocols

• To extend the range of a network by amplifying signals

• To connect multiple devices in a LAN

Which type of cable is typically used for high-speed internet connections and is made of glass or plastic fibres?

• Twisted pair

• Coaxial

• Fibre optic

• Aluminium

What is the main role of a router in a network?

• To act as a central hub for wireless connections

• To forward packets between networks

• To regenerate and amplify weakened signals

• To block unauthorized access

Which device is essential for connecting to the internet by converting digital data into analog signals?

• Repeater

• Modem

• Switch

• Hub

What is the function of a repeater in a network?

• To connect multiple devices in a LAN

• To extend the range of a network by regenerating and amplifying signals

• To monitor and control network traffic

• To convert digital data into signals

Which device allows wireless-capable devices to connect to a wired network?

• Firewall

• Wireless Access Point

• Network Interface Card

• Router

What is the primary difference between a hub and a switch in a LAN?

• A hub operates at the network layer, while a switch operates at the Ethernet layer

• A hub forwards data only to the intended device, while a switch transmits data to all connected devices

• A switch forwards data only to the intended device, reducing collisions

• A switch operates at the Ethernet layer, while a hub operates at the link layer

What is the purpose of a Network Interface Card (NIC) in a computer?

• To act as a barrier between internal and external networks

• To connect a computer to a network by converting digital data into signals

• To extend the range of a network

• To forward packets between networks

Which of the following is NOT a type of cable used for transmitting telecommunication signals?

• Twisted pair

• Coaxial

• Fibre optic

• Satellite

In which scenario would a repeater be most beneficial?

• In a small home network with few devices

• In a large building where signals weaken over distance

• In a network that requires blocking unauthorized access

• In a network that needs to convert digital data into analog signals
