  • Why do some laptops have microSD slots?

    I was reading a review of a laptop and it said that the laptop includes a 'microSD slot (up to 256GB)'. However, I was under the impression that microSD slots applied only to devices like tablets and phones, and as a means of expanding their storage?

    Plus, given that some laptops also have SD card slots, what is the distinction between the two and their respective purpose?

  • What can an external SSD be used for?

    I recently purchased a new laptop that has an internal SSD. I then came across a review of an external SSD. 

    What can external SSDs be used for? Plus, why would someone wish to buy an external SSD over an external hard drive? Is it simply a question of speed?

  • Do I need to adjust the Wi-Fi option in Windows Settings to get an ethernet connection?

    I recently asked whether I need to obtain a USB to ethernet adapter in order to be able to get a wired, ethernet connection for my Windows 10 laptop, as it doesn't have an ethernet port. The consensus was that I do.

    However, once I do that and connect it, do I then need to move the Wi-Fi option in Windows Settings to 'off'?

    Or will simply connecting the ethernet cable be all I need to do in order to get that wired connection and thus the faster speeds? Will my laptop make any kind of acknowledgement that I am now using an ethernet connection?

  • Do I need a USB to Ethernet adapter?

    I figure I do, but before I spend cash I just wanted to be sure. 

    I have an old Windows 7 laptop which has what I assume would be described as an Ethernet port - and indeed, my Ethernet cables slotted in. 

    Now I've bought a Windows 10 machine and, just as there is no in-built optical drive, there's also no Ethernet port - only what I assume are USB-C ports, but then I'm quite new to computing. 

    In order to use the Ethernet cable to create a wired connection between my router and my laptop, can I simply purchase a 'USB to Ethernet Adapter', or might there even be a cheaper option? It's annoying to buy a new laptop then immediately have to spend more money on an optical drive and other peripherals.

    Whether it be the theory of evolution or the theory of gravity, what level of acceptance and endorsement does there need to be in order to say that there exists a scientific consensus about something?

  • Why does my Kindle lose battery life when it's switched off?

    Why does my Kindle e-reader lose battery life even when I switch it off? Recently, I had about 60% battery life but switched it off and didn't use it for around a week. Upon firing it up, the battery had drained completely. 

    Although it's 5 years old, it still works well.

  • How do ISPs handle customers' data?

    Leafing through a computer magazine the other day, it mentioned that although using incognito mode in a web browser won't leave a history or cookies, it still won't prevent your ISP - among others - from knowing which sites you've visited.

    But what do ISPs do with this information? Is any employee free to dip in at any one time? Do ISPs have a system in place so that if someone accesses an illegal site they're alerted?

  • Why might a hardcover book not get released in paperback?

    More often than not, a book that is released in hardcover often appears in paperback around a year later. But I've noticed that some titles - admittedly, often comparatively obscure ones - do not get issued in a paperback format.

    Is this simply because the hardcover edition didn't sell particularly well?

  • How is it that dogs can see ghosts?

    I have read books on the paranormal and also watched paranormal TV shows, and it has been observed how dogs can suddenly become very agitated and begin barking at someone (or something) in, say, the corner of a room, when there doesn't appear to be anything there. 

    I don't know if any other animals exhibit this behaviour, but are there any parapsychological theories which seek to account for this? 

    By what means could a dog see or sense a ghost - assuming of course that such things exist?

  • Do people recommend living in an apartment or advise against it?

    I have been thinking of buying an apartment, since I feel one would suit my needs. However, most people advise against it, telling me communal living is too noisy and that when problems arise, it could prove very costly.

    What has been your experience?

  • Was this a demon or a psychic joker?

    I came across an intriguing story of the paranormal recently that was related by a third party.

    Two fairly young people were in a room and were fooling around with a tape recorder. They happened to record themselves singing a christian hymn which mentioned Jesus. They didn't notice anything unusual during the recording but, upon playing it back, part way into their singing a harsh voice could be heard over their singing. Clearly referring to Jesus, it thundered, 'HE IS WEAK BUT I AM STRONG!'

    The whole family was terrified and the third party happened to observe that the voice sounded 'old' - the implication being of course that it could be a demon. They were also puzzled as to how the voice had managed to get on to the recording, given it wasn't heard at the time.

    My question to psi researchers is: how can we know if this was really a demon, rather than just some psychic joker, and what do psi researchers have to say about the mechanism behind this phenomena, since I have read of similar occurrences in relation to electronic voice phenomena?

  • Can anyone explain how to read this nutrition table correctly?

    I have 4 slices of black pudding and I'm a little confused about how to correctly read the nutrition table on the back of the product. Please forgive my obtuseness.

    1. There is "energy kJ and "energy kcal". What is the "energy kJ" and am I right in assuming that the "energy kcal" (which is 325) is the one to go by if you're interested in counting your calorie intake?

    2. The packaging of the product says 227 g. Is this referring to the combined weight of all four slices or does it refer to each individual slice? The table shows, for example, that 11.0 g of saturated fat is contained per 100 g. So if I ate one slice would I therefore have eaten just over 22 g of saturated fat assuming that each slice is 227g?

    3. Why is there a row showing sodium and another row beneath it that says 'equivalent as salt'? I thought sodium and salt were the same things?

  • What are programming and coding and is there a difference between them?

    I am an older computer user and have noticed that programming and coding are being mentioned more and more in the news. But as someone who only uses the internet to send e-mails, shop online, download music, etc. I do not understand what these ideas are about.

  • Is China the main offender in state-sponsored hacking or is the reality more complicated?

    I was reading an article recently about a security researcher who created a series of 'honeypots' - vulnerable, important-looking computer systems - in order to tempt international hackers. Over the subsequent month there were 39 attacks from 14 different countries. More than a third of these seemed to come from China, but apparently this may not necessarily be the case since apparently hackers often use Chinese characters and code in order to hide their paymasters' real country of origin.

    So what is the truth and why use Chinese characters and code anyway in order to conceal the origin of the hacking?
