64 kilobytes of memory
operated at 0.043MHz.
An iPhone 5s has a CPU running at speeds
of up to 1.3GHz
and has 512MB to 1GB of memory
Cray-1 (1975) produced 80 million Floating
point operations per second (FLOPS)
10 years later, Cray-2 produced 1.9G FLOPS
An iPhone 5s produces 76.8 GFLOPS – nearly
a thousand times more
Cray-2 used 200-kilowatt power

4. Computing Power
4
−Smaller size
−More Powerful
−More memory and more storage
−"Moore's law" over the history of computing, the
number of transistors in a dense integrated circuit
has doubled approximately every two years.

6. The Internet:A brief history
6
− 1961: Leonard Kleinrock at MIT published the first paper on
packet switching theory in July 1961.
− 1962: J.C.R. Licklider of MIT discussed his "Galactic Network"
concept - a globally interconnected set of computers through
which everyone could quickly access data and programs from
any site.
− 1968: an RFQ was released by DARPA for the development of
one of the key components, the packet switches called
Interface Message Processors (IMP's).
− The RFQ was won in December 1968 by a group headed by
Frank Heart at Bolt Beranek and Newman (BBN).

7. The Internet:A brief history
7
− 1970: the Network Working Group (NWG) working under S.
Crocker finished the initial ARPANET Host-to-Host protocol,
called the Network Control Protocol (NCP).
− 1972: Bob Kahn organized a large, very successful
demonstration of the ARPANET at the International
Computer Communication Conference (ICCC).
− This was the first public demonstration of this new network
technology to the public.
− 1972: the first "hot" application, electronic mail, was
introduced.

8. The old Internet timeline

9. TCP/IP in the early days of the Internet
9
− The original Cerf/Kahn paper on the Internet described one
protocol, called TCP, which provided all the transport and
forwarding services in the Internet.
− A 32 bit IP address was used of which the first 8 bits signified
the network and the remaining 24 bits designated the host on
that network.
− The assumption was that 256 networks would be sufficient
for the foreseeable future…
− Obviously this was before LANs (Ethernet was under
development at Xerox PARC at that time)

10. Expansion beyond estimation
10
In November 1979, a proposal was submitted
to NSF to fund a consortium of eleven
universities at an estimated cost of $3 million
over five years. This is viewed as too costly by
the NSF.

11. Predicting the future (in 1999)!
11
− 1999:“The number of hosts (locatable through DNS) will
exceed 100 M, very soon!”
− A few years later in 2013, 80 “things” per second were
connecting to the internet. In 2014 that number was around
100 per second, and by 2020, more than 250 things will
connect each second. (source Cisco)
− It is estimated that by 2020 there will be more than 50 billion
internet connected devices. (source Cisco)

12. Submarine cables

13. Fiber optic cables around the world
A single fibre can
transmit as much as 100
billion bits per second
(100 Gbps, about ten
thousand times faster
than a typical home
broadband connection)
- A cable can contain
hundreds of fibres, a
single cable can have
enough capacity for the
communications of
millions of users.

the internet

16. Connectivity and information exchange was
(and is ) one of the main motivations behind
the Internet; but Content and Services are
now the key elements;
and all started growing rapidly by the
introduction of the World Wide Web.

Internet of Things (IoT)
− Extending the current Internet and providing connection,
communication, and inter-networking between devices and
physical objects, or "Things," is a growing trend that is often
referred to as the Internet ofThings.
− “The technologies and solutions that enable integration of
real world data and services into the current information
networking technologies are often described under the
umbrella term of the Internet of Things (IoT)”

46. Applications and potentials
− Analysis of thousands of traffic, pollution, weather, congestion, public
transport, waste and event sensory data to provide better transport and
city management.
− Converting smart meter readings to information that can help prediction
and balance of power consumption in a city.
− Monitoring elderly homes, personal and public healthcare applications.
− Event and incident analysis and prediction using (near) real-time data
collected by citizen and device sensors.
− Turning social media data (e.g.Tweets) related to city issues into event and
sentiment analysis.
− Any many more…
46

47. The physical world data
− Multi-modal and heterogeneous
− Noisy and incomplete
− Time and location dependent
− Dynamic and varies in quality
− Crowed sourced data can be unreliable
− Requires (near-) real-time analysis
− Privacy and security are important issues
− Data can be biased- we need to know our data!
− Data alone may not give a clear picture -we need contextual
information, background knowledge, multi-source information
and obviously better data analytics solutions…
