Explanation​

 

[abiodun1991]

Why might your actual internet speed be different from what your ISP advertises?
Because of network congestion and other factors
Because ISPs often overpromise and underdeliver
Because of the type of devices you use
Because of the weather

Explanation​

 

[abiodun1991]

What is different between bits and qubits?
Bits can handle more data than qubits
Bits can be either 1 or 0, while qubits can be both 1 and 0 at the same time
Bits are more powerful than qubits
Bits are used in quantum computers, while qubits are used in regular computers

Explanation​

In modern smartphones, what input device allows you to interact with the device using your fingers?
Keyboard
Scanner
Mouse
Touchscreen

Explanation​

The correct answer is Touchscreen.

Touchscreens on modern smartphones allow users to interact with the device using their fingers, enabling direct manipulation of the screen to control functions like typing, swiping, and tapping.

What does Unicode provide that ASCII does not?
Support for only English characters
Support for special characters
Support for emojis
Support for numbers

Explanation​

The correct answer is Support for emojis.

Unicode provides a much broader range of characters compared to ASCII, including support for multiple languages, symbols, and special characters, such as emojis. ASCII, on the other hand, is limited to 128 characters and primarily supports English letters, digits, and a few special symbols. Unicode encompasses all of these and extends to a vast array of characters used worldwide.

What should you do if the fix might cause a lot of downtime for the organization?
Implement the fix immediately
Cancel the fix
Wait until after hours or the weekend
Ignore the downtime

Explanation​

The correct answer is Wait until after hours or the weekend.
If a fix might cause significant downtime for an organization, it is generally best to schedule it during off-hours or the weekend to minimize disruption to regular business operations. This approach ensures that critical systems remain available during peak business times, while still allowing necessary maintenance or updates to be applied.

 

[precious]

What should you do if you can't find a solution to the problem on your own?
Restart the device
Ignore the problem
Give up
Ask for help

Explanation​

The correct answer is Ask for help.

If you can't find a solution to a problem on your own, it's always a good idea to seek assistance from colleagues, supervisors, or external experts. Collaboration often leads to quicker and more effective problem-solving.

Why might your actual internet speed be different from what your ISP advertises?
Because of network congestion and other factors
Because ISPs often overpromise and underdeliver
Because of the type of devices you use
Because of the weather

Explanation​

The correct answer is Because of network congestion and other factors.
Actual internet speed can differ from what an ISP advertises due to several factors, including network congestion, distance from the server, the quality of your router, the number of devices connected, and even the type of connection (wired vs. wireless). While ISPs may advertise speeds "up to" certain limits, various conditions can cause fluctuations in the real-world performance you experience.

What is different between bits and qubits?
Bits can handle more data than qubits
Bits can be either 1 or 0, while qubits can be both 1 and 0 at the same time
Bits are more powerful than qubits
Bits are used in quantum computers, while qubits are used in regular computers

Explanation​

The correct answer is Bits can be either 1 or 0, while qubits can be both 1 and 0 at the same time.

Bits are the fundamental unit of data in classical computing, representing a value of either 0 or 1. In contrast, qubits (quantum bits) are used in quantum computing and can exist in a state of 0, 1, or both 0 and 1 simultaneously, thanks to a property called superposition. This unique capability allows qubits to perform complex calculations much more efficiently than classical bits.

What does it mean to consider multiple approaches?
Ignore all other possible causes
Focus on one solution until it works
Immediately call technical support
Try different methods to identify the problem

Explanation​

The correct answer is Try different methods to identify the problem.

Considering multiple approaches means exploring various methods or solutions to understand or resolve an issue, rather than sticking to just one potential solution. This can involve testing different troubleshooting techniques or analyzing different aspects of the problem to find the most effective resolution.

How many potential values can a single bit store?
answer
1
8
2
256

Explanation​

The correct answer is 2.

A single bit can store one of two potential values: 0 or 1.

Why is it difficult to increase CPU speeds beyond current levels?
It needs more storage space.
It requires more internet bandwidth.
It generates too much heat.
It consumes too much electricity.

Explanation​

The correct answer is It generates too much heat.

Increasing CPU speeds beyond current levels can lead to excessive heat generation, which poses challenges for cooling and reliability. As processors run faster, they produce more heat, and managing that heat is critical to maintaining performance and preventing damage. While power consumption is also a concern, heat dissipation is a primary factor in limiting further increases in CPU speed.
