ICT General Knowledge 5 — Questions and Answers
Question 1: Which encryption standard is commonly used to secure wireless networks today?
- WEP
- WPA
- WPA2/WPA3 (Correct answer)
- TKIP
Correct answer: WPA2/WPA3
WPA2 and WPA3 are the current standards for securing Wi-Fi networks, offering strong AES encryption.
Question 2: What is 'latency' in the context of networking?
- The total amount of data transferred per second
- The time delay between sending and receiving data (Correct answer)
- The number of hops a packet takes
- The physical distance between two servers
Correct answer: The time delay between sending and receiving data
Latency is the time delay measured from when data is sent to when it is received, typically measured in milliseconds.
Question 3: What is the purpose of a VPN (Virtual Private Network)?
- Increase internet connection speed
- Create a secure, encrypted connection over a public network (Correct answer)
- Replace the need for a router
- Block advertisements on websites
Correct answer: Create a secure, encrypted connection over a public network
A VPN creates an encrypted tunnel between your device and a server, securing your data and masking your IP address.
Question 4: In software development, what does 'API' stand for?
- Automated Programming Interface
- Application Programming Interface (Correct answer)
- Applied Protocol Integration
- Advanced Processing Instruction
Correct answer: Application Programming Interface
An API (Application Programming Interface) defines rules and protocols for how software applications communicate with each other.
Question 5: Which of the following correctly describes 'machine learning'?
- Programming a computer with explicit rules for every situation
- Training computers to learn from data and improve performance without being explicitly programmed (Correct answer)
- Replacing human workers with robotic machines
- Using computers to repair other computers
Correct answer: Training computers to learn from data and improve performance without being explicitly programmed
Machine learning enables computers to learn patterns from data and make decisions or predictions without explicit rule-based programming.
Question 6: What is the difference between a virus and a worm in cybersecurity?
- A virus is more dangerous than a worm
- A worm requires human action to spread, while a virus spreads automatically
- A virus needs a host file to spread, while a worm can self-replicate and spread independently (Correct answer)
- There is no difference; the terms are interchangeable
Correct answer: A virus needs a host file to spread, while a worm can self-replicate and spread independently
A virus attaches to a host file and spreads when that file is shared, while a worm self-replicates and spreads across networks without a host.
Question 7: In computing, what does 'GUI' stand for?
- General Usage Interface
- Graphical User Interface (Correct answer)
- Global Unified Index
- Generated Utility Input
Correct answer: Graphical User Interface
GUI (Graphical User Interface) allows users to interact with software through visual elements like icons, buttons, and windows.
