The
new MacBook Pro has ensured goodbye to USB type A, a connector on Macs for
almost twenty years and that has made the story of Apple, and more. A painful,
but inevitable transition.
The
Universal Serial Bus (known by all as USB) is an interface that older MAC users
have learned to know at the time of the first IMac, the first model of Apple's
second life, which enshrined the return home of Steve Jobs and who has (re)
launched Apple In the world of casual computing and (then) different.
But
in spite of rumors that today shout to the scandal for the lack of presence of
the connector more using in the history of computer science in the new models,
at first things did not go Toppo well: in 1998 computers, especially Macs, were
mostly a Office accessory or graphic studio, hard to find them in the living
room or bedroom, having to stop the PCs, cheaper and suitable for an industry
with which Apple never (really) tied up, the games.
The
USB input in the Mac World (in version 1.1) coincided with the farewell of the
SCSI connector, a little soft passage that, if in the Windows world was well
received (where SCSI never really arrived) in that Mac was like a trauma.
Elephant
memory
USB
had the huge advantage of being able to be plugged in "hot", which
meant a computer turned on, was smaller and could be used for both external
memory units (disks and keys) and for peripherals (mice, keyboards, pads and
more on IPod, IPhone and headphones), But it had the huge drawback of being
very slow (12 Mbps rated against the 40 of the Ultra Wide SCSI).
Not
missed so much that Apple joined to usb the FireWire, more expensive but more
capable of USB for disks and memory drives, which already beat 10 to 1 SCSI.
But
the history and fame of USB, despite the early moans, grew fast aided
especially by the diffusion in Windows, where FireWire is never (really)
arrived. In 2000 came the USB 2.0 format, backward compatible with USB 1 and
1.1 and capable of a nominal transfer rate of 480 Mbps, more or less when Apple
passed to the FireWire 800 format (which dubbed the first FireWire in all,
including speed , but had a different connector).
Apple
took a while to adopt the new USB 2.0 format that came three years later than
the Windows world, a very mature market.
The
USB 2.0 format was a revelation: they blossomed hubs of all kinds, practically
any accessory was equipped with a USB port and also the series of IPod,
initially based on FireWire, passed to USB mainly because of compatibility with
the Windows world, then A key turning point in the market.
Mice,
keyboards, headphones, speakers, graphic tablets, MP3 players, ipods, iphones,
ipads, clocks, mechanical discs, flash drives and keys or even only bulbs, fans
and accessories for intimate use are now sold with a USB connector. Whether you
are exchanging data with the computer or drawing only to the power of the
channel to date a USB connector is much more universal, for example, an
electrical outlet (which is subject to the change of characteristics and form
of country in the country).
USB,
a nice type
But
despite the diffusiore of oil, in memory of those who write far greater than
any other hardware standard in the world of computing, the history of USB is
not without shadows, misunderstandings and controversial aspects.
The
duality with SCSI and FireWire, albeit in specific areas was short-lived, but
it is undeniable that the story will bring it back. Much more controversial was
the history of the connectors, of which USB is well stuffed.
The
type a connector, what we all know, rectangular with a footprint in the center,
is the typical USB connector that stops (VA) computer side.
It
is estimated that it was a technical limit of the time to determine its
asymmetric shape, which still makes it difficult to insert it into a computer
(especially in an iMac), but it was not the only one. Also the choice to create
a second USB connector type B, of square shape, which typically rests on the
device side, turned out in uncomfortable time.
Minor
aspects, or not
Not
to mention the little precision of the cables: a USB 1.1 and 2.0 cable are
different internally (but they use the same connectors) and can frustrate some
advantages of the second, I have never been regulated a standard wording to
alert the Users, who Tipicametne once opened the box had no way of
distinguishing the difference between them if not trying it on the field.
To
make things difficult have arrived other connectors, always USB 2.0, probably
asked by the big computer manufacturers and devices to minimize the spaces.
Mini USB was the first attempt to replace the type B connector with a smaller
one, which has spread a lot in cameras, 2.5 "discs, camcorders
To
make things difficult have arrived other connectors, always USB 2.0, probably
asked by the big computer manufacturers and devices to minimize the spaces.
Mini USB was the first attempt to replace the Type B connector with a smaller
one, which has spread much in cameras, 2.5 "discs, camcorders and
accessories such as graphics tablets, while in the printers sector the old Type
B connector still resists.
This
has succeeded the Micro USB, which today dominates the market thanks to the
diffusion in the smartphone sector (where it has become a standard) first and
accessories for smartphones then (as speakers and battery pack). Apple never
believed in the Micro USB preferring to impose its variant first in 6Pin
version and then Lightning, the first serial connector to be symmetrical.
But
if on the one hand the type B has ceded the step to the Mini USB first and
Micro USB then (with Variant Lightning), the type a connector has remained
unchangeable until today, switching to a version 3.0 unchanged aesthetically
(except for the internal dimensions often of blue color) Capable of bringing a
speed ten times higher than USB 2.0, but being backward compatible with it and
often even with the old standard 1.1. On the other side the type B has split
offering a normal variant and a Micro, aesthetically unwatchable, always
asymmetrical but very functional and economical.
This
is to say that you, the USB is a standard, you can connect practically
anything, from the mouse to the Hard Disk, from the Bluetooth speaker to charge
the battery to the portable fan. But it's not a standard that easy, to think
about it: four versions (1.0, 1.1, 2.0 and 3.0, the first ever arrived on Mac),
eight connectors, three cables and all intertwined with each other in spite of
users, who are often left to themselves and a drawer full or cables to which it
is difficult to give an order.
Apple,
first, had the courage and daring to impose a change, as it was at the time for
the Floppy, for the CD/DVD and for other abandoned hardware formats.
The
new advancing
The
USB 3.1 connector (also called type-C) is a very important change, and the new
MacBook Pro today offers a model historically equal to the first iMac in many
places of view.
The
first novelty is the unique connector, on both sides: this means that a cable
can do everything, connect to everything, without differences (for now, we will
see in the future).
The
second novelty is that cable and connector are symmetrical: We could connect
the cable to the connector without worrying about the verse, and the same on
the part of the device, being the two identical parts. In practice, type C is
the definitive connector: Considering that the current standard is also common
with Thunderbolt 3, with differences in performance but not of shape and
design, we expect a more rosy future, less anger and a more tidy cable tray.
Finally,
also from the software point of view things are certainly better: a USB 3.1
connector can drive a data connection with an external disk, a network
connection, drive an external display in 4k (or Anaogico in VGA) and also
provide an additional socket for the Old USB 3.0.
Sure,
it will take more than a few years before the market is adjust to the new
standard, that the investments of producers and users are based on the new
format instead of the old ones, we will probably spend a lot in adapters (here
a brief overview) that in aspirin When we forget them at home, but who writes
has already passed this stage so many times, and is still here.
The
USB 3.1, or USB-C HUB as the friends call
it, is here to stay, it says Apple, they will say it all sooner or later.
