The fact that the hdd light needs it's shape and meaning need explanation and are not trivially obvious makes me feel old.
Same for the save icon and phone icon, honestly.
"A floppy disk? Lmao that's outdated tech, gramps. Everybody knows MiniDisc is the future of storage tech."
*cries next to stack of MiniDiscs while listening to Alice in Chains using a MiniDisc Walkman*
@@CyanRooper Yeah, I think I still have an ls120 disk somewhere. Far better for compatibility than the Iomega drives, just to little to late. Today's floppy drive is the "thumb drive"
makes me realize how poor and backward area that I lived because most computer in here uses HDD and SSD categorized as gaming peripheral
I've used HDDs for a long time but they never looked like cylinders. How old do you have to be to think it's an obvious icon? And how many plates do you need to make a hard disk start looking like a cylinder?
Can you do a video on the difference between different types of screens? Like oled, amoled, qhd, lcd, etc?
They have done that already
@@Gala23Milk the only ones I can find are from a while ago, and don’t mention amoled
QHD is a resolution
@@hudsonr6358 amoled is just Samsung's version of oled. It's just for marketing because there's nothing special about it. Same with all the different names for oled Sony and LG have.
@@lucassilvas1guess this proves why a video is needed lol
When someone invents something, a logo to their new invention is found under pillow in the morning
If he go in vent he sus.
Wow, I did NOT know that!
Truly, it's a strange and magical world in which we live.
Why is this the techquickie logo?
Because it is a combination of the letters T and Q.
It's a T and a Q
Because Linus decided so.
The Q is also a question/speech bubble
It looks like a question mark and inside you can see a T, the question mark is shaped like a Q or speech bubble as well.
Here i was thinking the HDD activity light got its start from the old disk platters from the 60s where you had a big machine filled with like 25 inch disks.
I guess this is more apt explanation.
Yeah I thought about this too, back in the 50s and 60s hard disks were actually stacked inside massive cylinders so large they were transported with fork lift trucks.
"Dishwasher hard drives". The kind that held as much as a whopping ONE MEGABYTE of data on platters as big in diameter as a car tire.
I read that last line completely wrong
Actually it's an older reference than even that. It's a visual reference to drum memory. Dating from 1932! but widely used beginning in the 1950s: en.wikipedia.org/wiki/Drum_memory
4:35 I triple E
IEEE
Thank you, it felt weird hearing it as I E E E
A thunderbolt? It's a lightening bolt, thunder is the sound! These tech people spend so long indoors they never seen a storm haha
Ok, but how are you supposed to visually display the sound of thunder, without showing where it comes from?
I’m pretty sure sound isn’t supposed to be seen…
Nah mate, they listen to Queen
Or maybe someone's used to the Pokémon move term. 😏
AC/DC: "THUN-DER!!!"
Bluetooth was developed by Ericsson, rather than Intel
Yes, by a Dutch man called Jaap Haartsen.
In May 1998, the Bluetooth SIG was launched with IBM and Ericsson as the founding signatories and a total of five members: Ericsson, Intel, Nokia, Toshiba, and IBM.
The first Bluetooth device was revealed in 1999
As far as the name goes... It was an Intel guy who pushed it forward.
@@lexgso5141 The name Bluetooth and technology was already partially developed by Jaap Haartsen while he was working for Ericsson, later they founded Bluetooth SIG together with a bunch of other companies in which they further developed the technology. The name was not thought up of by an Intel guy... the name was already there before Intel was involved.
Also, if you turn the logo 90 degrees clockwise, it looks like little teefees.
3:06 skip ad
It is a shame a quarter of the video is an ad
The power on-off symbol may also be a representation of an old fashioned toggle switch, once common on electronic devises.
yeeeep. O and I have long been symbolic representations of "open" and "closed", which in the world of electronics means "disconnected" and "connected" respectively.
it's a bit counter-intuitive at first, but if you think about it as "someone drilled a hole through this wire" and "a normal wire" it becomes more clear what they mean lol.
The USB logo has multiple meanings but the most relevant ones are 2:
- the USB protocol uses a star topology. The logo kind of resembles it by showing multiple shapes connected to the same central node
- the various shapes are meant to symbolize the ability to use it with a wide variety of devices. USB was born with the intention to replace the unmanageable mess of different serial and parallel ports that devices used at the time.
There may have been other reasons, possibly the resemblance to copper traces on a PCB. The latter however seems improbable at best since the USB part that is seen is the outside connector, not the internal PCB traces.
That the two lines to the side branch out from the center one also indicates it's a bus.
USB was game changer when it first came out. It revolutionized computers. Before USB, connectors were massive and each one was different. Google "vintage computer joystick connector", and admire the 15 pin monstrosities that needed to be bolted down so they don't fall out.
@@dimruby I suppose you also remember the DB-25 or the monster DD-50 connectors... Chunky, heavy, they would rip out the connector on boards even when properly bolted... Horror tech stories :)
Looks like some kind of gender symbol.
I know the Bluetooth story i came for the usb answer you know, the one the title talked about 1:07
The cylindrical logo for storage activities resembles a drum memory
0:01 hello mobile users
Video ideas:
1. How internal fan headers regulate power delivery and therefore control fan speed.
2. The various “key” layouts for sata, m.2, ram, etc. and how they are decided from gen to gen.
3. The advantages and disadvantages of digital signals over analog and a breakdown of how analog signaling works.
RILEY!!!! Still rocking the next best hair on the platform! Second only to Kyle Hill of course. Tough to compete with "Science Thor" there.
On the USB logo .... in standard schematic and PCB design, the circle represents a power connection, the square represents ground and the arrow represents signal flow. Thus the USB logo signifies a PC powered peripheral device.
3:99 HEY, this is not an Intel invention this was a standard made of Swedish company Ericsson with Nils Rydbeck as the original creator and the later development by tasked the Norwegian Tord Wingren with specifying and Dutchman Jaap Haartsen and the Swede Sven Mattisson with developing. 1997 Örjan Johansson (Swede) became the project leader and propelled the technology and standardization, he was the one that made it Bluetooth why would some Intel employee randomly name something from Scandinavian history you need to fire your research team guys. All the development took place in Lund, Skåne (South of Sweden close to Denmark). I my self have family ties to this company as my grandfather was an of it many engineers.
This tbh, intel ? Really ?
@@abbe9641 I Think they used AI to research this, of course the AI made up some sh*t like AI does. Later in the history of Bluetooth there was a joint company for the standard that included Intel, but the standard was already named and set, that’s probably where the AI got Intel from. Really just double check the answer against Wikipedia at least, this is some really lazy sh*t.
Nobody said he invented the technology, only that he came up with the name. Try paying more attention.
@@QwerkyPengwen well that”s fu*king impossible because it was already named Bluetooth before Intel ever came into contact with. The first ever product to have the technology was an Ericsson cellphone. This is a lie plain and simple.
Harald Bluetooth was probably actually Harald Blacktooth. At that point in the development of the Nordic languages, blue and black were considered the same color*, just like how English considers cobalt and robin's eggs to both be "blue" but Russian and Italian consider them to be different colors.
* To be clear, there were different words for blue (blár) and black (svartr) which should look familiar to speakers of many modern Germanic languages, but the ways these words were used was highly context dependent, similar to how we don't describe a sheet of unused paper as "white" but rather as "blank" (which comes from the French word for white [blanc]), or how we have color words largely specific to hair (blond, brunette) and eyes (hazel) which rarely get used for other things, and how bruises are interchangeably described as "purple" or "black and blue." Gray (grár) often gets tossed in the mix as well. All of this is probably at least partially due to the distinction between these colors being fuzzy in nature. Floating ashes and wispy gray hair can appear blue, leading to the term "blue hair" referring to old people with gray hair and the depiction of e.g. various Hindu gods as blue (because they were covered in ashes). Organic things that usually look black (like crow feathers) often look blue under the right lighting conditions. And of course the sky and the ocean can appear black or blue or gray depending on weather conditions, time of day, etc. And since most color words originated as words for things typically of that color (see the much newer color word "orange" for instance, named for the fruit, or "turquoise," named for the stone) it took a long time for the oldest of these color words to affix consistently to specific colors as they originally referred to broad color ranges. Homer's Odyssey famously refers to the sea as "wine-dark" and this habit can be seen as recently as William Gibson's opening line for Neuromancer: "The sky ... was the color of television tuned to a dead channel." That last case is obvious poetic metaphor, but that's basically how all language gets built up over time.
I'm disappointed that for the hard-drive symbol you show a modern drive.
That's a symbol that goes back to the 60s. First we had "magnetic drum storage", and then when magneitc platter based "hard drives" came out they also existed in the same huge "drum" format. They looked like actual large cylinders.
When IBM started to codify their diagrams they used the "drum" to represent a database symbol, and that started to be used generically for any type of long term storage.
Bluetooth's designers wanted to call it PAN - Personal Area Network, but their suits told them they'd never be able to trademark such a generic word as pan.
I do like PAN as a generic term for wireless technology
BLUETOOTH: I thought it was simply a very radical and original symbol so that non-tech people could quickly and easily recognize it.
USB: I thought the root represented anything digital in general, while the branches unified everything digital as one. The top branch represents the past, the bottom branch represents the present, and the middle arrow signifies future-proofing.
HARDDRIVE: Everyone knows that, but there have been variations of that icon.
POWER: I thought the line represents a human finger hovering over a button.
*raises hand* -...isn't that technically a lightning bolt..? (Thunder = the sound)
Correct but it's WAY easier to understand at a glance what the logo represents and means instead of thunder. Idk how you'd even represent the sound in a logo, it'd just look like a wifi symbol or something that could be misinterpreted
Lightning is a proprietary computer bus and power connector, created and designed by Apple Inc. The icon showing a lightning is not for Lightning. It is for thunder... Crazy.
They manufacture squares, triangles, and circles at their factory

FUN FACT
OK was also initials of a German engineer Otto Krovens who worked for Ford car company in America.
As chief inspector he wrote his initial as OK upon each car he passed.
Hence it continued till date as All correct
Some say "oll korrect" as a misspelling of "all correct".
That's not the correct etymology.
"OK" does indeed stand for "oll korrect", but it's an intentional and humourous misspelling dating back all the way to 1838.
There was a fad of comical misspellings in the USA, starting in Boston. It's basically a Victorian-era (or rather a Martin-van-Buren-era) meme that managed to survive until this day.
"OK" was first used in writing in 1839, way before Henry Ford was even born, and I couldn't find any information on someone namend Otto Kroven.
I just hope people won't continue to use words like "rizz" until 2210. 😬
The power symbol is something that came to be understood as the power on or off switch, in part because a line breaking a circle as it does suggests a broken circuit. Breaking a circuit is literally how you disrupt power. The grandest irony about it, though, is that the symbol came to prominence and use as we went from a standard of a hard power switch (physically, directly breaking the main power delivery circuit) to a soft power switch (breaking or closing a circuit with a small amount of power to trigger a relay to open or close a larger circuit, or act as a signal to a more complex control system).
A switch that is fully on or fully off has a 1 encircled by a 0 (IEC 60417-5010). A switch that is fully on or in standby has a 1 encircled by a 0 (IEC 60417-5009). 30 years later in 2004, IEEE reimagined this as IEEE 1621 where the standby symbol just meant power, and a new symbol, a crescent moon, meant standby/sleep.

0:46 A NAAAAME THEORY
I’ll take my leave now
I've always been something of a geek with anything tech-related, and am a strong advocate for Affordance - making something new/unfamiliar similar to something old/familiar so that people intuitively understand it (even if they don't understand why they understand it). With that in mind, most of these designs are fairly obvious:
~ Bluetooth ~
While it is 100% true that the Bluetooth icon combined the Danish runes for H and B (in reference to its namesake), there were once many other competing technologies (some of which were technically superior) which all fell by the wayside. The star-like center of the Bluetooth icon intuitively reads as wireless omnidirectional connectivity, while the two triangles resemble the classic Play icon (used by everything from the old Walkman to UA-cam). Even a complete luddite can interpret the Bluetooth icon as something providing two-way wireless connectivity - in any direction, unlike its predecessors which primarily relied upon infrared (which is still used by most remote controls).
~ USB ~
Even if you know absolutely nothing about computers, this logo reads very intuitively - you have one larger device connected to multiple smaller devices simultaneously through a common channel. With the larger circle generally reading as a desktop computer, the smaller circle intuits as another computer (possibly a cell phone), which reads as a way for two computers to communicate (aka networking). Arrows are typical of indicating supply and flow, which makes the middle portion read for functioning as a power source for other devices. Boxes are typical of indicating storage, which makes the lower portion read as a portable storage device (aka thumb drive).
~ Power Icon ~
Whether you're European (where light switches are round rockers), American (where light switches are elongated toggles), or Old Skool (growing up with Ye Olde Toggle Switch), the Power Icon universally reads as a power switch. It's also (mostly) universal that all these switches are oriented such that they're moved upwards to activate. Hence, the icon resembles a switch in the on position. (The whole 'zero and one' thing is a techie backronym.)
Affordance - particularly in UI - runs so deep that many people never even think about it. (Sometimes to the detriment of developers, as so aptly demonstrated with the Windows 8 debacle.) Even when something is insanely outmoded, Affordance perpetuates itself. This is why the HDD activity icon still looks like a cylinder, despite many computers using 100% solid-state storage devices. This is why the Save icon looks like a floppy disk, even though floppy drives pretty much died a quarter century ago. This is why the Battery/Charging icon looks like a classic AA/C battery, despite the actual batteries looking nothing like one (and usually aren't replaceable). This is why Health is red and Mana is blue in virtually every video game ever made.
Why share logo looks like that?😂
The share icon represents one person (the one sharing) connected to two others. (Also it's not in Unicode because it's trademarked.)
@@m2pt5 So it's a binary tree?
I don't know when it really happened, or why, but the whole combined circle/line logo for power when separated circle represented a completed circuit and meant "on" while a line represented an incomplete circuit and thus meant "off." There are lots of electrical devices back in the 90s that followed this creed, but I think the inter-personal confusion about how different switches could be open to interpretation may have led to this strange shift in which meant on or off. Annoys me as a child of the 90s who knew and understood this concept, when things started doing it backwards and it somehow stuck.
That is interesting. And from my intuition I could argue that the circle is a wheel which depicts motion (=on), and the line is something standing still and depicts no motion (=off).
I always figured the thumbnail image was an in company sex joke that was forgotten but still used. Cause I'll be damned if that isn't one in the bum, one in the youwhoo and the last on the go button.
I always thought the hard drive light looked like a stack of CD's, like the ones my mom used to burn songs and pictures too
I am glad that we have stopped saying 'burn' meaning store.
The power symbol isn't a one in a zero. The wikipedia page states that is a common misconception. It is a "line" and a "circle".
The line, |, means power on. The circle, O, means power off. The line fully inside the circle means the switch physically removes all power. The line halfway in the circle (what you showed in the video) means the device "turns off", but still has a small portion of it powered which is how it can power itself back on.
Per the wikipedia page:
> The symbol for the standby button was created by superimposing the symbols "|" and "◯"; however, it is commonly interpreted as the numerals "0" and "1" (binary code); yet, the IEC holds these symbols as a graphical representation of a line and a circle.
If you look at older computers from the 90s, the power switch literally had AC mains voltage running through it. Turning off the switch effectively unplugged the computer -- nothing was powered. Those switches had | and O (or the stick fully inside the circle). Modern power switches have milliamps of low DC signal voltage controlling the always-powered motherboard.
Fun fact for all those UEFI only kids....
Back in the CMOS/BIOS days, you had to manually enter your Hard Drive information requiring:
Cylinders, Heads and Sectors (CHS), and during the early 1990's we got fancier LBA drives..... I have always attributed the HDD icon as a reference to the Cylinder part of the CHS term. Makes perfect sense.
The USB (Universal Serial Bus) logo is indeed composed of four connector types, which are represented by different shapes: A trapezoid (or a triangle with an extension), a circle, a square, and a delta.
The creator of this iconic logo was Jeff Kovaal, but the design process involved several individuals.
Jeff Kovaal worked at Intel Corporation in 1996 when he led the team that developed the USB standard. To create the logo, they consulted with Jerry Lowenthal from Intel's marketing department and other experts.
Their thought process for designing the logo focused on simplicity, clarity, and inclusiveness of various connector types used by different devices. The idea was to have a single symbol that could represent all four main types of connectors:
A trapezoid (or triangle with an extension) represents USB-A, which is commonly found in computers.
A circle represents the USB-B type, often seen on printers and scanners.
A square represents the mini-USB connector used by smaller devices like cameras and phones.
The delta shape was initially intended to represent a micro-connector but later replaced with an "extension" of the trapezoid (triangle) for consistency.
The design aimed to be easy to recognize, memorable, and versatile enough to work across various platforms without being too complex or confusing.
Lol, I never thought about the logo being under a pillow! 😄 It's cool how all these symbols have hidden meanings. Makes you see tech in a whole new light! 💡 Would love to hear more fun stories behind other logos! Maybe a video on the history of the power symbol too? ⚡
Im pretty shure the bluetooth guy (harrald gormsson blåtan) his initials where HB, and HB in nordic rune symbols create more or less the bluetoth symbol.
Oh an btw, blåtann is actualy direct translation to blue tooth, kinda sick!
Also, "blå" (blue) was the word for black, since there just was no special word for black back then. Bad teeth, like Harald allegedly had, being black is after all more common than them being blue. At least linguistically, black was considered a very dark shade of blue. For example, "blåmän" (blue-men) is an archaic Swedish word for Negroes and possibly other dark-skinned peoples encountered by early Nordic adventurers and traders.
While having proposed the name, that Intel guy had nothing to do with the development of bluetooth. The tech was developed by Ericsson Mobile in Sweden, specifically by the Dutchman Jaap Haartsen.
How about "Winchester" drives?
I always thought the power logo was flipping the bird, "You think it's gonna turn on! HA"
Funny, my HCI teacher said "nobody knows where the power symbol comes from"
I had an old vacuum that had a switch with a separate circle and a line on it so it seemed obvious to me
At 4:00, it can also indicate an open and closed circuit, for electrical engineers.
My uncle worked for USB after leaving his job at Sega, and he said the USB symbol was modeled after Hanson the Butler's hand from Scary Movie.
Love these Techquickie videos.
I come from a different universe where the circle meant complete circuit and the line meant broken circuit.
Actually, King Bluetooth was the guy who invented the first Sharpie, back when blue dyes were the only machine-washable dyes available. He had a bad habit of chewing the pen tips, hence, Bluetooth. ‘Blueteeth’ would likely have been a more accurate nickname, but “Bluetooth” sounds way more badass, so that’s what they went with, and it stuck.
Machine washable huh? LOL :)
In the 'old days', power switches were mounted through front panels or casings of appliances by a round knurled nut and had a lever to flip up or down to turn the device On or Off.
THAT's what the power logo represents, nothing what so ever to do with '1's and '0's.
Looking at the usb graphic, it appears to include information. It can be used to connect two sources (pc's) or pc to peripheral, or pc to other devices such as storage, hence the 2 symbols for pc in the first row, a single direction in the second (old mouses/keyboards) and a square device in the third row (usb storage, printers, etc with bidirectional communication, but where pc is still source)
You can't connect two PCs using USB, so that can't be right. I'm guessing the square is a keyboard, the arrow is a mouse, and the circle is a camera.
@@pauldzim you absolutely can, they're called transfer cables
The USB symbol was explained to me to represent that it replaced many cables with just one. That is a lightening symbol, not a thunderbolt LOL. None of my pc's have ever had a symbol for HDD like the one you show. It has always been nothing but a light blinking. The power symbol is standard for about everything that operates with electric power. You are right about it being representative of a binary code though.
Cause Marvel already trademarked Namor's trident?
Posted this before watching and seeing the Poseidon reference lol
3:37 memory unlocked - I still have no idea what the Turbo button did and if it always needed to be pressed, why wasn't it running automatically
So this is where Riley was! 😆
I think the USB logo looks more like a flowchart
I have such a deep crush on this man... That mustache does things to me...
More simple electronics still run on 1s and 0s. They obviously aren't as complicated as your PC but does still represent turning a circuit on and off to turn the device on/off.
Those of us that were desktop techs and network engineers in the 1990's can tell you that the invention of USB was every bit "that big of a deal." lol
The bluetooth symbol is pretty clever. Thanks for the history lesson!
The HDD logo comes from the very first hard disk solutions that used 60cm (24in) platters, stacked in a tall column (50 platters).
As a logo, it was hard to convey the sense of platters, thus, only the outer shape has been kept - which, you guessed it, looks like a cylinder. Look up the IBM 350 (RAMAC) for an awesome journey in the past of storage technology!
There are variants with separation circles that sort of resemble multiple platters (usually 3, but I have seen variants with 4), however they are less common.
Fun fact: if you look up a generic "database" icon, the same cylinder / platters logo comes up! With the current SSD technology there is imagery portraying more squarey shapes, but very often, separation layers exist in the imagery, keeping continuity with the good old cylinder / platters logo.
I always figured the power symbol represented open/closed, like you see printed on a couple of places on machinery (especially with small engines).
Thought the different shapes on the USB warned that it's impossible to insert it the right way round without at least three attemps.
I remember reading about USB in PC Magazine slightly before it hits the shelves. They were showing keyboards with a USB port to plug your mouse into it, and were saying how great it is that all USB evices are daisy chain-able. That might have influenced the logo, either that or the hub architecture that ended up winning
USB devices are not daisy chain-able. FireWire devices are daisy chain-able.
I always thought the power icon represented a toggle switch. I guess it represents both a toggle switch and binary 1/0. Thanks for sharing.
Thunderbolt is not self explanatory at all! Thunder is sound!
This video is wrong. Hard drive symbols have a DRUM logo, as they used to be giant iron oxide covered cylinders called drums.
Because it connects to circles, triangles and squares.
i guess we doin circles now
I anticipated that segue and turned the other cheek
I've never personally never seen a thunderbolt during a storm. I've seen a lightning bolt, and heard thunder.
We're going to have to now explain the hard drive symbol to our kids just like the floppy disk "save icon".
I did not know the origins of the power logo. It's very interesting.
-- Grandpa Riley! Tell me about those me-cha-nee-kal drives from your times!
-- Sonny, what the hell are you talking about, they still available for purchasing for regular people in regular retail shops.
Being old enough to have to have suffered through a different fucking serial port for every single peripheral device, I can say with confidence that yes, USB really is that exciting.
I somehow knew the history of most of these icons, except for the thunderbolt logo which I didn't realise was a lightning bolt...
The thing I find funny these days is that a modern SSD is still called such - a Solid State _Drive_ - even though it's not actually driven any more. In years to come, this is going to seem so quaint and old-fashioned (once people forget about mechanical data storage that actually used a physical motor to *drive* its spinning platters.) 😁
It seemed so new back then but the odd shapes feels so 90/2000’s now in a nostalgic and quirky way
Blue was the word for black in old norse
"Back when we were all using HDDs..."
I still use them exclusively.
The power logo looks like it's an open circuit and if the "1" flips to it's side (or rotates 90 degrees) it closes the circuit.
Idk Riley, I thought we were a similar age... I remember when USB came out. It was pretty fucking exciting. Not only did it not need thumb screws, it also was hot pluggable. Before that, you had to power down your pc before plugging something in.
I would say the USB logo looks more like a bus transit map or metro transit map. The different shapes look like different stations.
It's because that's the face I make when I put the USB in the wrong way.
USB logo was apparently made by Jim Dowse (working at DEC at the time) for a friend who was appointed to the International Symbols Committee by the company... he did many others but the USB one is the most famous.
The original USB logo with the PC and peripherals was supposed to show that you can tether devices on one USB cord. I forgot what they said the limit was, like 128 devices or something? It was a high number. I remember when it came out. Anyway, not knowing this shows your age. The reality is that no one really tethered their devices no one hub that often.
note the power button logo or XBOX logo as some say. is found on buttons that function as both ON and OFF. for switches like the one on your power supply the 1 and 0 are shows independent.
Huh, I always thought the power logo came from the shape of tubular locks, which look exactly the same. Though I don’t know how often they are used to toggle the power of something.
Whoa! What was up with that computer with a lock!? And, where can I get such an electrical lock!?!?
The meaning of the USB logo has always seemed self explanatory.
It is interesting that there is certain reasons for these symbols I just assumed they were all standardization that were created by some insane guy in a room and had no actual purpose or reasoning but "oh the strong circle with a line through it totally looks cool lets use that!"
I swore all of these were covered in another tech quickie. But honestly even if it was I'd forget I watched it and just rewatch anyway.... because my human brain can't remember jack.
knew the bluetooth one, and had assumed the power one, but the USB one was kind of interesting
i have a drive activity light, and i have literally used it for any reason whatsoever. not once. i always wondered why a modern case even has it, but i never REALLY thought about it.
My laptop is in runes.... ¯\(°_o)/¯
There was indeed a weird time when pc makers felt the need to make a new graphical language.
Like I get it but at the same time, it feels like they took themselves a little too seriously in retrospect.
I believe that the power button simbol is the combination of a 1 for on and a 0 for off, but I might be mistaken
What about 1 for standing still (off) and 0 for rolling as a wheel (on)?
I prefer to think of the on/off symbol as a person with a tiny finger pressing a very large power button.
I always thought the usb symbol looked like a stick figure taking a briefcase to work.
The reason the HDD icon looks like a can is because of a much older technology than HDD platters, It's a visual reference to "drum memory" common in the 1950s & 60s. en.wikipedia.org/wiki/Drum_memory
1) The USB clearly represents the user (big circle) and the three tries it takes to get the plug in.
2) Why does the IO power logo look like every electrical device's power knob then?
IEEE is usually pronounced as "I triple-E"
Tom Scott made a dedicated video about the bluetooth logo with some more information. For those interested.
There are two versions of the power logo depending on if it's on and off or standby. See Tom Scott's video.
