Has its own operating system, memory and sometimes own file system
Clusters use message passing technique to retrieve and pass data from one node to another
Cluster computing has improved reliability and speed provided by single computers

A group of networked computers which work together as a virtual supercomputer
Use to solve complex problems with large computational power such as climate modeling, drug design and protein analysis
Computers are loosely coupled, heterogeneous and geographically dispersed
eScience-Open Grid Computing Environment Toolkit
Developed by Lanka Software Foundation
Provides a platform for scientists to compose, execute, monitor and share their experiments as scientific work flows
Conducted to solve problems in domains such as particle physics, bio-informatics, earth sciences
Parties involved in these projects belong to different organizations such as governments, universities and private firms
Aims to minimize the barriers by not only automating scientific workflows
Type of computation in which execution of processes are carried out simultaneously
A computational task is broken down into several very similar sub tasks that can be processed independently
Results are combined afterward upon completion
The gap between individuals, households, businesses and geographic areas
At different socio-economic levels
With regard to both their opportunities to access information and communication technologies (ICTs) and to their use of the Internet for a wide variety of activities
Bridging the Digital Divide
ICTA initiated the Nenasala project in order to raise the IT literacy of Sri Lanka
Ways of Measuring Digital Divide
Access infrastructure – e.g. mobile phones, TVs, community access centres
Communication infrastructure – Internet bandwidth, mobile phone coverage, telephone, Internet/broadband
Household income and whether there is capacity to purchase and subscribe to ICTs
ICT skills curriculum in education
Government policies for enabling access (e-government, competition/regulatory frameworks, tariff structure)

Implemented under the e-Sri Lanka Initiative
Known as the “Vishva Gnana Kendra Project (Nenasala)”
Introduce several models of the tele-centres or knowledge centres to be established in all parts of Sri-Lanka
To spread ICT services to the rural and semi-urban population.
The main objectives of a Nenasala is to assist communities in:
Poverty reduction
Social and economic development, and
Peace building
Creation of virtual machines that act like a real computer with its own OS

Multiple instances of such virtual machines are run on one physical machine

Goal - Consolidate hardware resources


Digital Divide
Infrastructure of the Internet
IPv6
IPv6 is the next generation of the Internet protocol
IPv4 allows for four billion IP addresses
IPv6 provides for 3.4 x 1038 addresses
Auto-configuration
Devices can be configured automatically when connected to IPv6 network
Multicast
Source sends information only once, to be received by many, which helps with network efficiency
Jumbo grams
IPv4 has a limit of 64kB payload while IPv6 can do up to 4GB

Internationalized Domain Names (IDN)
IPv6
Security
IPSec, the protocol for IP network-layer encryption and authentication, is an integral part of the IPv6 base protocol
Mobility
File or data transfer can continue uninterrupted as a device “roams”
Quality of service
There is better support for multimedia and other applications requiring quality of service
Better routing features
There is more efficient fragmentation reassembly and support for today’s networks and routers
Virtual infrastructure or hardware

Internal business networks such a private clouds and virtual local area networks

Hardware resources for virtual server space, network connections, bandwidth, IP addresses and load balancers

A branch of Computer Science
Pursues creating computers or machines as intelligent as human beings
AI is accomplished by studying how human brain thinks and how humans learn, decide, and work while trying to solve a problem
Then used outcomes of this study as a basis of developing intelligent software and systems
Goals of AI
To Create Expert Systems − Systems which exhibit intelligent behavior, learn, demonstrate, explain and advise its users
To Implement Human Intelligence in Machines − Creating systems that understand, think, learn, and behave like humans

Lanka Government Network (LGN) 2.0 has been proposed by ICTA to be implemented from 2016-2018
LGN 2.0 aims at connecting a significant amount of government locations and each location will be provided with wi-fi facility
It is intended to provide high speed and secure connectivity for all e-Government initiatives
Wi-Fi
Use radio waves to create a communication link between two or more points with end devices using Ethernet to complete the link
Range of a Wi-Fi access point which allows Wi-Fi enabled equipment to communicate with each other
Indoors - around 30 metres
Outdoors- around 100 metres
Worldwide Interoperability for Microwave Access (WiMax)
Overcome limitations of DSL and Wi-Fi by providing high-speed broadband access over wireless technology
Cheaper to deploy and widespread coverage similar to that of mobile phone networks
WiMax specifications allow speeds up to 70Mbps and a range up to 50 km from base station with no line-of-sight requirements between user and base station
Can operate at various frequencies ranging from 2GHz-11GHz and 10GHz-66GHz
The Internet of Things enables objects sharing information with other objects/members in network, recognizing events and changes so to react autonomously in an appropriate manner
The IoT therefore builds on communication between things (machines, buildings, cars, animals etc.) that leads to action and value creation
IoT is also expected to generate large amounts of data from diverse locations, with consequent necessity for quick aggregation of data and increase in need to index, store, and process such data more effectively
IoT is one of the platforms of today's Smart City, and Smart Energy Management Systems
A term for data sets that are so large or complex that traditional data processing software is inadequate to deal with them
Big data can be analyzed for insights that lead to better decisions and strategic business moves
Key Characteristics
Volume- Data Quantity
Velocity- Data Speed
Variety- Data Types, Big Data analysis includes different types of data
Long Term Evolution (LTE)
Standard for high-speed wireless communication for mobile phones and data terminals
It increases the capacity and speed using a different radio interface together with core network improvements
3rd Generation (3G)
The third generation of wireless mobile telecommunications technology
3G mobile phones are multimedia devices (Smartphones) with ability to access the Internet, send and receive audio and video
Smartphones include productivity applications like document editors
3.5G and 3.75G refer to more recent releases of 3G technology
Allow for higher data speeds with speeds ranging from 7.2Mbps to 56Mbps or more depending on technology deployed by service provider
4th Generation (4G)
Fourth generation of mobile phone communication technology and is successor to 3G and earlier standards
4G sets peak download speed for mobile users at 100Mbps and for fixed users at 1Gbps
4th Generation (4G)
In 2014, Sri Lanka was the first country in the region to get 4G thanks to Dialog
In 2015, Sri Lanka was ranked as one of the leading countries with the fastest internet speeds in South Asia
In 2016 June, Sri Lanka beacame 21st country that has 4.5G Internet
This was confirmed by a successful test by Dialog using Huawei’s infrastructure
