the two original connector specifications for USB Were A and B
don't you love it when Engineers name things with both male and female
connector types for each female a receptacles were intended for host
devices like computers the ones that control the transfer of data over the
USB connection while female B receptacles were intended for Upstream
peripheral devices printer scanners CD burners and the like most cables feature
a male a connector and a male B connector of some sort because with the
exception of on thee-o capable devices there's no reason to connect two hosts
to each other or two peripherals now back to the original standards I don't
want to hate on them or anything they did Propel the universal serial bus to
damn near ubiquity in the Computing world but they had some fairly
significant limitations they were large bulky and fragile rated at a mere 1,500
insertion Cycles they were only designed to deliver a little bit of power the
speeds at which they operated quickly became a bottleneck and finally
particularly irritating on the a connector they only went in one way
without any clear visual indication of which way was right leading to awesome
computer nerd jokes like how many tries does it take to get a plug into a USB
connection four twice to get it wrong once to think you got it wrong and one
more time to put the damn thing in so that you can hear that ever so
satisfying now many of these issues have been improved over the years almost
right away USB 2.0 dramatically improves speeds without requiring ing new
physical connectors or cables mini and micro versions of the B connector were
developed to be more durable and more suitable for devices that fit in your
pocket and more recently the backwards compatible USB 3.0 standard brought
about new ab and microe connectors that
add physical pins to dramatically improve speed and power delivery again
to keep USB competitive with newer standards like EA and Thunderbolt and
that's where we're at today but can USB be even better Apple sure thought so
introduced their proprietary lightning connector which is smaller rugged enough
for me to sleep with my phone under my pillow without worrying about breaking it and reversible but unfortunately
still limited to USB 2.0 speeds so
there's still room for improvement and here it is the future is now the USB
type-c connector has been finalized and if it delivers what it's promising it's
going to basically kick all those other connectors to the curb with a completely
redesigned connector designed to deliver up to double the data of USB 3.0 10 GB
per second up to 100 watts of power so you could conceivably power a monitor or
charge your laptop off of it really you can't go 4 seconds without reusing a
joke anyway back on topic it has a slim design with a 10,000 cycle durability
rating so you can use the same cables across all your different devices and
not worry about breaking them and
finally it has a reversible connector so
you never have to play guess the orientation again speaking of
orientation today's episode of how not to shave is brought to you by Dollar
