Total questions: 15
Worksheet time: 8mins
Which term best describes a system of interconnected computers and devices that can share data and resources?
Protocol
Network
Packet
Topology
What is the process of sending digital information from one device or location to another called?
Fault tolerance
Data transmission
Packet switching
Network mapping
Data can move through different types of networks. Which pair correctly names the two examples highlighted in class?
LANs and WANs
PANs and MANs
VPNs and ISPs
Servers and clients
Which option correctly defines protocols in the context of networking?
Physical pathways that carry electrical signals
Sets of rules that determine how data is communicated between devices
Small units that data is broken into while traveling
Alternative routes a network uses during failures
When data travels across a network, it is often broken into small units. What are these units called?
Frames
Segments
Packets
Blocks
Which statement best captures the meaning of fault tolerance for a network?
The network can send larger packets without delay
The network keeps working even when part of it fails
The network prevents all security threats automatically
The network uses only wired connections to avoid interference
What term describes a simplified visual or physical representation of how a network is set up and how data moves through it?
Network protocol
Network diagram or model
Network packet
Network gateway
Reliable networks often include __________ paths or backups so that if one path fails, data can still get to its destination. Which term best completes the sentence?
single or one
redundant or alternative
random
temporary
Fault tolerance helps prevent __________ or loss of service when a part of the system isn’t working. Choose the best word to complete the sentence.
downtime
latency
bandwidth
encryption
Which practice directly improves a network’s reliability by finding and fixing issues before they become problems?
Increasing user passwords length
Analyzing the network for possible failures or weaknesses
Installing only one router to simplify paths
Turning off monitoring to reduce alerts
Why is fault tolerance important in a network? Select the most accurate reason.
It guarantees infinite bandwidth for all users.
It allows service to continue even when some components fail.
It eliminates the need for backups and maintenance.
It prevents all cyber attacks automatically.
Which set of elements is most likely included in a basic network model?
Users, applications, and data flows
Only cables and connectors
Printer ink levels and paper trays
Weather forecasts and temperature sensors
You are designing a school network and want it to keep working if part of it goes down. Which approach best supports reliability?
Use a single switch so there’s only one device to manage.
Rely on manual data transfers between classrooms.
Provide redundant paths and regularly analyze for possible failures.
Disable monitoring to prevent false alarms.
Which statement best contrasts how data typically moves on a LAN versus a WAN?
LANs usually transmit data over short distances within a building or campus, often achieving lower latency and higher speeds than WANs.
LANs primarily connect devices across cities and countries, leading to higher latency than WANs, which are limited to a single room.
WANs are designed for very short-distance connections with minimal equipment, while LANs rely on long-distance leased lines.
WANs always provide faster speeds than LANs because they use wireless signals exclusively.
During a video call, the audio starts cutting out and the video becomes very pixelated. Which network improvement would most directly help prevent these symptoms?
Increase available bandwidth or prioritize real-time traffic (QoS) to reduce latency and packet loss.
Disable all encryption so packets travel faster across the internet.
Switch from a LAN to a WAN so the call uses longer paths and more intermediate networks.
Limit devices to 2G mobile data so the connection remains consistent.
