The fastest is always the attraction !! ~ the man
in the photo is happily glued to his mobile, just most people are – walking,
talking, driving, eating and what not! – happy browsing and whiling away on
social media.
At Tokyo Olympics 2020, Thompson-Herah stole the show with a quite
breath-taking 10.61sec run that broke Florence Griffith-Joiner's 1988 mark by
one hundredth of a second. She was followed over by double champion Shelly-Ann
Fraser-Pryce in 10.74sec and Shericka Jackson in 10.76sec in a Jamaican
1-2-3. In Men’s 100M sprint - Marcell
Jacobs of Italy sprinted to Olympic gold
finishing in 9.80 seconds. Fred Kerley of the United States finished
second in 9.84 seconds, and Andre De Grasse of Canada was third (9.89).
At the time
of posting this – one web revealed ‘Your Internet speed is 85 mbps; another one
put it at 93.7 - yet another one showed it at 97 mbps – it is actually slightly
less than half of the speed promised by ISP – yet am happy, because when I
upload say 30 odd photos to a post in FB – they get uploaded in less than a
minute or slight above ! .. .. and life
goes on happily browsing so many and downloading so much !!
About a two decades and a half-ago, accessing web was not
easy. One needed a telephone connection
and another from an ISP – there were no modems but ‘dial-up’ connection. Remember that in mid 1990s, an external
Agency came to our Training centre for teaching Officers, what ‘Internet’ and
‘world wide web’ is about – after close to a dozen attempts, they failed miserably
with the net not connecting and not taking to any of the searched information
! - those were the days of ‘dialler
connection’ that used the public switched telephone network (PSTN) to establish
a connection to an Internet service provider (ISP) via telephone lines.
Remember purchasing Mantra Online and Dishnet packs for usage –
and some of us bought another telephone line as We were not able to call or
receive calls when connected to the internet.
Present generation would never be able to understand that we existed
without ‘mobile connection’ and the landline could get disconnected so often !!
and for talking to people farther, one had to go the Public telephone booths or
book trunkcall !! When the dot.com
bubble burst, many were swept out. VSNL,
Dishnet, Now ISP, Mantra Online – one may not remember or know
them now …. they were the service providers for Dial-up connections, widely
used a decade ago.
‘Wireless
connections’ changed the way people
access web. The Wi-fi technology uses radio waves to provide wireless
high-speed Internet and network connections. Some say that term Wi-Fi is not short for "wireless
fidelity," but it actually is a trademarked phrase that means IEEE
802.11x. Wi-Fi is defined as any
"wireless local area network" (WLAN) product based on the Institute
of Electrical and Electronics Engineers' (IEEE) 802.11 standards". The
debate over just how dangerous small electromagnetic signals are has been going
on for years. Doctors in the United States launched an unofficial campaign last
year to try and limit women’s exposure to phones, computers, microwave ovens
and wireless equipment, claiming the radiation they emit poses a threat to
developing babies.
The speed of
your broadband (always-on, high-capacity, wide-bandwidth) internet connection
has never been more critical. It's the pipe that connects your computers,
tablets, handhelds, entertainment systems, and home automation tools, to the
outside world—and to each other. Your connection must
handle content that is critical for work, play, and keeping in touch. It has to
back your modern-day communications, from simple text up to voice calls and
video conferencing. And don't forget gaming: without the internet, your gaming
would be just lonely, single-player action. All that requires the best speeds.
Internet service providers
(ISPs), the companies that bring the high-speed broadband connections to your
doorstep, have increased speeds in the last few years. The FCC re-defined
broadband in 2015 to mean a minimum download speed of 25Mbps and upload speed
of 3Mbps, up from 4Mbps down and 1Mbps up.
Competition would help even more. There are entire cities now that can claim
gigabit internet status—ISPs there, frequently municipally owned or a utility
company, offer connections of 1 gigabit per second (Gbps) or more. That's 1,000
times better than 1Mbps speed, and 40 times what the FCC defines as broadband.
Recently read a newsitem
in MailOnline that Japan smashed the record for data transmission speed,
achieving 319
terabits per second along a 1,864 mile-long optical cable - fast enough to
transfer 10,000 HD movies in one second
In July 2021, Japanese
researchers achieved record breaking data transfer speeds through a long 1,864
mile optical cable, reaching a lightning fast 319 terabits per second. This is
fast enough that you could transfer 10,000 high definition movies at about 4
Gigabytes each in just one second, although won't be available to the average
home. This sort of technology is used in the back-end networks of broadband
providers and then split up among hundreds or thousands of customers. This new record smashes the previous best
speed for data transfer over a long distance of 172 terabits per second, also
set by a team from Japan's National Institute of Information and Communications
(NICT) in Tokyo. The new system is compatible with existing infrastructure,
meaning networks could be easily upgraded, as the cable is the same size, the
team explained.
Researchers say these sort
of speeds will be necessary for back-end-infrastructure as services place ever
greater demands on internet infrastructure, including through faster speeds
from 5G networks, as well as the internet of things and streaming. Data is then
transmitted using 'wavelength-division multiplexing', a technology that takes
the data beamed by a laser and splits it into 552 channels. Unlike earlier
generation amplifiers, these have been laced with rare Earth elements such as
thulium and erbium as they act to excite ions and boost the signal strength.
Overall each channel was
transmitting data at about 145 gigabit per second for each of the four cores,
or about 580 gigabits per second for all cores combined. With 552 channels of
transmission, this allowed them to achieve the record-setting 319 terabit speed.
Despite all the extra cladding for the four cores, it has the same diameter as
a standard single-core optical fibre cable. They are now working to work to increase
transmission capacity, extend the range and make it faster to match potential
demand as the world moves beyond 5G.
Our understanding of 2G in
India was very different and most of us without understanding the speed limits
are happy posting in Social media and playing games on the net.
Happy WWW & Internet
of Things
