What is the primary function of a switch in a LAN?
Broadcasts data to all devices
Sends data only to the intended device
Translates IP addresses to MAC addresses
Converts digital to analogue signals
Which device allows a LAN to connect to a WAN such as the internet?
NIC
Switch
Router
Hub
Which of the following devices assigns IP addresses dynamically to devices on a LAN?
Modem
Hub
Router
NIC
Which is a benefit of using a network instead of stand-alone computers?
Higher maintenance cost
Central data backup
Fewer software licenses required
Devices cannot share printers
What distinguishes a switch from a hub?
Hubs only work on wireless networks
Switches send data to a specific device
Switches use coaxial cables
Hubs have built-in firewalls
What is the main advantage of using fibre optic cables in a wired LAN?
Cheapest cable type
Most affected by interference
Highest data transmission rate
Suitable only for short distances
A LAN is most likely to be used in:
A multinational corporation
A network of ATMs
A school building
A university campus
Which device is responsible for converting digital data to analogue and vice versa?
Router
Modem
Bridge
Switch
Which characteristic best describes a WAN?
Uses only private communication lines
Covers one building only
Is cheaper than a LAN to maintain
Connects LANs over a large area
What is a major drawback of using a wireless network?
Devices must be physically connected
More vulnerable to data interception
Cannot support mobile devices
Higher cost than fibre optics
Which device connects two LANs using different protocols?
Switch
Router
Gateway
Repeater
What is a function of a repeater in a network?
Converts protocols
Assigns MAC addresses
Boosts signal strength
Blocks unauthorised access
Which of the following is NOT a benefit of networking devices?
Easier to install than stand-alone systems
Software can be shared between users
Central data storage
Easier access control
Which of the following is a characteristic of a WLAN?
Uses fibre optic cabling
Cannot connect to routers
Uses wireless signals for short-range communication
Slower than a WAN
Which of these is NOT an advantage of using a wired network?
More stable connection
Greater mobility
Faster data transmission
Less interference
Which component is essential for a computer to connect to a network?
Modem
Switch
Network Interface Card (NIC)
Bridge
In which scenario is a switch preferred over a hub?
When devices do not need IP addresses
When network efficiency and security are important
When using a wireless connection
When connecting to the internet
Which of the following is a limitation of fibre optic cables?
High installation cost
Poor resistance to interference
Low transmission speed
Frequent signal loss
Which feature is most commonly associated with a wireless router?
Converts analogue to digital signals
Provides Wi-Fi access and routing functionality
Offers only LAN connectivity
Requires coaxial input only
What is the purpose of encryption on wireless networks?
Increases signal range
Boosts internet speed
Prevents unauthorised access to data
Connects to multiple routers
What is the main role of a router in a network?
Connect devices inside a LAN only
Direct data packets between different networks
Store files for network users
Boost network signal strength
Which address does a router use to decide where to send a data packet?
MAC address
Port number
IP address
URL
What does it mean when a router acts as a DHCP server?
It provides firewall protection
It automatically assigns IP addresses to devices
It translates between different protocols
It blocks harmful websites
In home networks, a single device often acts as a router and also:
A repeater
A hub
A switch and wireless access point
Firewall and file server
Which of the following is not typically a function performed by a router in a network?
Connecting a LAN to a WAN
Filtering network traffic for security
Acting as a wireless access point
Printing documents for network users
