Introduction
● IT is advancing and changing at rapid pace because of Internet (TCP/IP)
● Access to Internet become necessity.. from fiber optic to 3G, 4G, WiMAX etc
● Everybody is getting connected and make themselves available and accessible anytime and anywhere
● This is achieved through advanced in software applications and technology use by Google, Twitter, Facebook etc..
● What are the software technology behind this?

Internet (Based on TCP/IP)
1965: Two computers at MIT Lincoln Lab communicate with one another using packet-switching technology
1968: Beranek and Newman, Inc. (BBN) unveils the final version of the Interface Message Processor (IMP) specifications. BBN wins ARPANET contract
1972: BBN’s Ray Tomlinson introduces network email. The Internetworking Working Group (INWG) forms to address need for establishing standard protocols
1973: Global networking becomes a reality as the University College of London (England) and Royal Radar Establishment (Norway) connect to ARPANET. The term Internet is born.

Internet (Based on TCP/IP)
1974: Vinton Cerf and Bob Kahn (Fathers of the Internet) publish "A Protocol for Packet Network Interconnection," which details the design of TCP
1982: TCP and IP, as the protocol suite, commonly known as TCP/IP, emerge as the protocol for ARPANET. (IPv4 to IPv6)
1987: The number of hosts on the Internet exceeds 20,000. Cisco ships its first router
1990: Tim Berners-Lee, develops HyperText Markup Language (HTML)
1991: World Wide Web is introduced to the public

Transmission Medium
● coaxial cable, the first broadband transmission medium, invented by AT&T in 1929 for Ethernet (Local Area Network (LAN)):
– at 400MHz, Cable Loss 5.5dB/100ft
– at 20GHz, Loss ~ 100dB/100ft
● Data Rate of 10-100Mbs
6 Of 70
Transmission Medium
● Twisted Pair cabling:
– Shielded Twisted Pair (STP) & Unshielded Twisted Pair (UTP)
● UTP: most popular network cable in data networks for short/medium length (up to 100 meters or 328 feet) BW ~ 1GHz
– Loss ~20dB/100m at 100MHz
– Data Rate of 40Gbs (50m) – 1 pair of cable
– 100Gbs (15m) – 1 pair of cable
– 1 Gigabit Ethernet (GE) – 250Mb/s per pair (there are 4 pairs)
– 10GE? Heavier, difficult to maintain → Fibre is the best option
7 Of 70
Transmission Medium
● Fiber Optic
– BW 1THz, Loss ~ 0.93dB/1km
● 26 Terabit/s in 1 Wavelength channel at 50km
● Explosive of mass data! -> Internet of Things (IoT)
** Fiber Optics is chosen NOT because of signal speed in compare to any copper based medium.. speed of electron and photon are similar!!* It is chosen because of BW and low loss.

● Free and open sharing increases access to education and knowledge for anyone, anywhere, anytime
15 Of 70
Open Courseware (OCW)
● People want to learn
● free and open access to education and knowledge, people can fulfill these desire
– Workers can learn something that will help them on the job
– Faculty can exchange material and draw on resources from all around the world
– Teachers can find new ways to help students learn
– People can connect with others they wouldn’t otherwise meet to share information and ideas
– Materials can be translated, mixed together, broken apart and openly shared again, increasing access and allowing new approaches
– Anyone can access
– New Term: MOOC (Massive Online Open Courses)

In Terms of Open Standard
17 Of 70
Important of an Open Standard?
Standards, instructions or “blueprints” that are created and maintained in an open manner.
Using a democratic approach where no single individual or company controls the standard.
Open standards provide choicechoice and interoperabilityinteroperability between systems.
* Note: Examples of media formatting, .doc, .docx, odt, mp3, mp4, ogg)

In Terms of Open Technology
19 Of 70
● OSS == FS (at this moment..)
● A type of software defined by its collaborative development model, accessibility of code and distribution models.
– Examples are GNU/Linux OS, gcc, LibreOffice, Xpdf, GIMP etc.
● This is in contrast with proprietary software which is only available in a binary or “closed” format and typically carries a license fee.
– Examples are Microsoft Mobile, Windows XP, Vista, 8 Microsoft Visual C/C++, Borland C, MS Office 2007, Adobe Photoshop etc.
Open Source Software (OSS) or Free Software (FS)?

GNU is Not Unix (a recursive acronym!)
● Started by Richard Stallman in 1984, an MIT Richard Stallman in 1984, an MIT researcherresearcher, in a time when Unix sources were no longer free.
● Initial components: C compiler (gcc), make (GNU make), Emacs, C library (glibc), coreutils (ls, cp ...)
● However, in 1991, the GNU project was still missing a kernel and was running only on proprietary unice, until the invention of Linux kernel!!

Summary of FOSS
• Everybody wants to SHARE
• Free Software provide FREEDOM
• provide access, choice and allows innovations
• Internet (TCP/IP) is FOSS
• FOSS technology been around for ~ 40 years
• FREEDOM best describe as Free Software and not Open Source Software
• Software is Free ($$) but services (installation, training, consultation) is not!
• The world is accepting FOSS and going towards “Openness”
• avoid unethical attitude if using PIRATE SOFTWARE

Next Slide (if we have more time) is on FOSS Licences (Brief)
64 Of 70
FOSS Licences
Copyright is a set of exclusive rights granted to the author or creator of an original work:
● includes the right to copy, reproduce, distribute and adapt the work.
Copyright owners have the exclusive right to:
● exercise control over copying and other exploitation of the works for a specific period of time.
● Anyone requiring to exploit and use any copyrighted work requires permission to use that work.
● Can grant permission and grant license for exploitation of the work.
65 Of 70
FOSS Licences
Copyleft is a term used in respect of FOSS licensing which is used for copyright:
● Copyleft is a practice of using copyright law to offer the right to distribute copies and modified versions of a work and requiring that the same rights be preserved in modified versions of the work.
Main idea behind copylefting the open source software was:
● to not let the product fall into the domain of proprietary software. If open source software is put into public domain with no copyright, people can make the said software proprietary and it would defeat the whole purpose of open source freedom.
● To guarantees that every user has the freedom.
66 Of 70
FOSS Licences
Copyright law has been used to withhold permission:
● to copy, modify or distribute software,
Copyleft ensures that the project remains free, and all modified and extended versions of the program remains free as well.
Proprietary software developers use copyright to:
● take away the users' freedom;
Copyleft guarantees their freedom.
That's why the name has been reversed from “copyright” to “copyleft”
67 Of 70
FOSS Licences
FOSS licenses are categorized as:
● strong,
● weak or
● with no copyleft provisions
Non-copyleft licenses, also known as permissive licenses, allows those using the software to re-license it under any terms as they want.
The most popular copyleft license is GPL.
The most popular non-copyleft license is BSD style. These licenses place no restriction on licensing for modified works.
68 Of 70
The strength of the copyleft governing a work is an expression of the extent that the copyleft provisions can be efficiently imposed on all kinds of derived works
FOSS Licenses - Copyleft
