Question 1

Which operating systems are most widely used?

Accepted Answer

Google and Windows

Answer

'Google' here likely refers to Android (for mobile devices) and Chrome OS (for laptops), while 'Windows' refers to Microsoft Windows (for desktop and laptop computers). These two ecosystems dominate the global market share for both mobile and desktop operating systems, respectively. Android is the most widely used mobile OS, and Windows holds the largest share in the desktop OS market.

Question 2

What type of USB connector is growing in popularity due to its speed?

Accepted Answer

USB-C

Answer

USB-C is rapidly gaining popularity due to its reversible connector, versatile functionality, and significantly faster data transfer speeds compared to older USB types. It supports various protocols like USB 3.1/3.2 and Thunderbolt, enabling high-speed data transfer, video output, and power delivery through a single port. Its adoption across new devices highlights its efficiency and future-proofing capabilities.

Question 3

The infrastructure of a network

Accepted Answer

All of the above

Answer

Network infrastructure encompasses all the hardware and software components that enable network connectivity, communication, and management. This includes physical components like wired (Ethernet cables) and wireless connections (Wi-Fi), as well as networking devices such as routers, switches, and servers. The internet itself is a vast global network infrastructure, relying on these underlying components.

Question 4

To carry out an appropriate search you should:

Accepted Answer

Use top-level domains

Answer

While all options relate to web browsing, using top-level domains (like .gov, .edu, .org) can significantly enhance the appropriateness and reliability of search results. These domains often indicate authoritative sources, helping users filter for credible information. Typing into the search bar is how you initiate a search, and checking for security is important, but using TLDs is a specific strategy for *appropriate* search quality.

Question 5

This sorting method has the least complexity in the worst-case scenario.

Accepted Answer

Merge sort

Answer

Merge sort consistently exhibits a time complexity of O(n log n) in its worst-case, average-case, and best-case scenarios. This makes it a very stable and reliable sorting algorithm, especially when compared to Quick sort, which can degrade to O(n^2) in its worst-case, or Bubble sort, which is always O(n^2) in its worst and average cases. Its divide-and-conquer approach ensures predictable performance.
