ICT SECTOR IN MALAYSIA

ICT Sector in Malaysia
The last two decades in Malaysia has been considered to be the era of wireless communications being led by two major trends: the outburst of wireless access communications - offering mobility to the telephone users and the mobile multimedia, and the increasing number of mobile communications subscribers.

Broadband penetration rate has increased from 10,9 for every 100 households in 2006, to 33,2 as of March 3, 2010, whereas the mobile phone penetration rate has breached the 100% threshold (per 100 inhabitants) in Q1 this year, and expected to reach 108,1% by Q1 2010 (Q4 2009: 106,2%)

Transformation to Internet Protocol Era
Meanwhile, the physical work for the High Speed Broadband (HSBB) project has begun in May 2009, with its retail services expected to be rolled out in some parts of the country by March 24, 2010. This RM 11,3 billion project, which is part-funded by the Malaysian government, is supposed to offer bandwidth at network speeds of 10Mbps where 1,3 million premises in the country will be covered under the project within the next 2-3 years.

This project is widely seen as instrumental in transforming the country's telecommunications infrastructure into the Internet Protocal era, where households and businesses will be getting broadband network access for triple play services (voice, video and internet). For example, there is a plan to move the country into digital TV era, with analogue swiff-off planned in 2015.

The overall Malaysian telecommunications industry has a market size of more than RM 40 million, whereas the network telecommunication market is said to be worth around RM 5 billion with a compounded annual growth rate of more than 50%. This sector will continue to represent one of the most important arenas of research and expansion in the ICT industry in Malaysia.

ICT IN MALAYSIA

Malaysia Case Study
Malaysia is, in many ways, an atypical country. It is hard to categorize and neither developed nor developing, or both, depending on the region. It is characterized by great disparities within the country and faces the dilemma of ensuring its regional and global competitiveness in ICT while at the same time ensuring equitable ICT access in rural areas. Thus there are projects such as the Multimedia Super Corridor (MSC), a government-driven initiative to develop a Malaysian Silicon Valley, as well as the Internet Desa, a program to install Internet centers in rural areas.
The Internet is developing rapidly in Malaysia, helped by some of the lowest dial-up rates in the world (around 40 US cents per hour). As a result, there were some 1.2 million Internet subscribers—the majority residential—at the end of 2000 with an estimated 15 per cent of the population using the Internet. Broadband access is predominantly via leased lines. Asynchronous Digital Subscriber Line (ADSL) technology is being tested but is not yet widely available. Pay television service is mainly through Direct-to-Home satellite technology so cable modem access is not an option in Malaysia. Another option for broadband access is through fixed wireless but there are a number of technical and regulatory challenges to overcome in this area.
An ITU team, consisting of Vanessa Gray, Michael Minges and Lucy Firth, carried out field research for Malaysia from 2-6 April 2001. The Malaysian Communications and Multimedia Commission (CMC)—the country’s Information and Communication Technology (ICT) regulator—served as counterpart and organized meetings with relevant government and industry organization.

ict

introduction - what is ICT?
You see the letters ICT everywhere - particularly in education. But what does it mean? Read our brief introduction to this important and fast-changing subject.
ICT is an acronym that stands for Information Communications Tecnology
However, apart from explaining an acronym, there is not a universally accepted defininition of ICT? Why? Because the concepts, methods and applications involved in ICT are constantly evolving on an almost daily basis. Its difficult to keep up with the changes - they happen so fast.
Lets focus on the three words behind ICT:
- INFORMATION- COMMUNICATIONS- TECHNOLOGY
A good way to think about ICT is to consider all the uses of digital technology that already exist to help individuals, businesses and organisations use information.
ICT covers any product that will store, retrieve, manipulate, transmit or receive information electronically in a digital form. For example, personal computers, digital television, email, robots.
So ICT is concerned with the storage, retrieval, manipulation, transmission or receipt of digital data. Importantly, it is also concerned with the way these different uses can work with each other.
In business, ICT is often categorised into two broad types of product: -
(1) The traditional computer-based technologies (things you can typically do on a personal computer or using computers at home or at work); and
(2) The more recent, and fast-growing range of digital communication technologies (which allow people and organisations to communicate and share information digitally)
Let's take a brief look at these two categories to demonstrate the kinds of products and ideas that are covered by ICT:
Traditional Computer Based Technologies
These types of ICT include:
Application
Use
Standard Office Applications - Main Examples
Word processing
E.g. Microsoft Word: Write letters, reports etc
Spreadsheets
E.g. Microsoft Excel; Analyse financial information; calculations; create forecasting models etc
Database software
E.g. Oracle, Microsoft SQL Server, Access; Managing data in many forms, from basic lists (e.g. customer contacts through to complex material (e.g. catalogue)
Presentation software
E.g. Microsoft PowerPoint; make presentations, either directly using a computer screen or data projector. Publish in digital format via email or over the Internet
Desktop publishing
E.g. Adobe Indesign, Quark Express, Microsoft Publisher; produce newsletters, magazines and other complex documents.
Graphics software
E.g Adobe Photoshop and Illustrator; Macromedia Freehand and Fireworks; create and edit images such as logos, drawings or pictures for use in DTP, web sites or other publications
Specialist Applications - Examples (there are many!)
Accounting package
E.g. Sage, Oracle; Manage an organisation's accounts including revenues/sales, purchases, bank accounts etc. A wide range of systems is available ranging from basic packages suitable for small businesses through to sophisticated ones aimed at multinational companies.
Computer Aided Design
Computer Aided Design (CAD) is the use of computers to assist the design process. Specialised CAD programs exist for many types of design: architectural, engineering, electronics, roadways
Customer Relations Management (CRM)
Software that allows businesses to better understand their customers by collecting and analysing data on them such as their product preferences, buying habits etc. Often linked to software applications that run call centres and loyalty cards for example.
Traditional Computer Based Technologies
The C part of ICT refers to the communication of data by electronic means, usually over some distance. This is often achieved via networks of sending and receiving equipment, wires and satellite links.
The technologies involved in communication tend to be complex. You certainly don't need to understand them for your ICT course. However, there are aspects of digital communications that you needs to be aware of. These relate primarily to the types of network and the ways of connecting to the Internet. Let's look at these two briefly (further revision notes provide much more detail to support your study).
Internal networks
Usually referred to as a local area network (LAN), this involves linking a number of hardware items (input and output devices plus computer processing) together within an office or building.
The aim of a LAN is to be able to share hardware facilities such as printers or scanners, software applications and data. This type of network is invaluable in the office environment where colleagues need to have access to common data or programmes.
External networks
Often you need to communicate with someone outside your internal network, in this case you will need to be part of a Wide Area Network (WAN). The Internet is the ultimate WAN - it is a vast network of networks.ICT in a Broader Context
Your ICT course will almost certainly cover the above examples of ICT in action, perhaps focusing on the use of key applications such as spreadsheets, databases, presentation, graphics and web design software.
It will also consider the following important topics that deal with the way ICT is used and managed in an organisation:
- The nature of information (the "I" in ICT); this covers topics such as the meaning and value of information; how information is controlled; the limitations of ICT; legal considerations
- Management of information - this covers how data is captured, verified and stored for effective use; the manipulation, processing and distribution of information; keeping information secure; designing networks to share information
- Information systems strategy - this considers how ICT can be used within a business or organisation as part of achieving goals and objectives
As you can see, ICT is a broad and fast-changing subject. We hope our free study materials (revision notes, quizzes, presentations etc) will help you master IT!

Virus

A virus (from the Latin virus meaning toxin or poison) is a small infectious agent that can replicate only inside the cells of other organisms. Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms, from animals and plants to bacteria and archaea.[1] Since the initial discovery of tobacco mosaic virus by Martinus Beijerinck in 1898,[2] about 5,000 viruses have been described in detail,[3] although there are millions of different types.[4] Viruses are found in almost every ecosystem on Earth and these minute structures are the most abundant type of biological entity.[5][6] The study of viruses is known as virology, a sub-specialty of microbiology.
Unlike prions and viroids, viruses consist of two or three parts: all viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. (Viroids do not have a protein coat and prions contain no RNA or DNA.) Viruses vary from simple helical and icosahedral shapes to more complex structures. Most viruses are about one hundred times smaller than an average bacterium. The origins of viruses in the evolutionary history of life are unclear: some may have evolved from plasmids—pieces of DNA that can move between cells—while others may have evolved from bacteria. In evolution, viruses are an important means of horizontal gene transfer, which increases genetic diversity.[7]
Viruses spread in many ways; plant viruses are often transmitted from plant to plant by insects that feed on sap, such as aphids, while animal viruses can be carried by blood-sucking insects. These disease-bearing organisms are known as vectors. Influenza viruses are spread by coughing and sneezing. The norovirus and rotavirus, common causes of viral gastroenteritis, are transmitted by the faecal-oral route and are passed from person to person by contact, entering the body in food or water. HIV is one of several viruses transmitted through sexual contact and by exposure to infected blood.
Viral infections in animals provoke an immune response that usually eliminates the infecting virus. Immune responses can also be produced by vaccines, which confer an artificially acquired immunity to the specific viral infection. However, some viruses including those causing HIV and viral hepatitis evade these immune responses and result in chronic infections. Microorganisms also have defences against viral infection, such as restriction modification systems which restrict the growth of viruses. Antibiotics have no effect on viruses, but several antiviral drugs have been developed.

Virus

In computers, a virus is a program or programming code that replicates by being copied or initiating its copying to another program, computer boot sector or document. Viruses can be transmitted as attachments to an e-mail note or in a downloaded file, or be present on a diskette or CD. The immediate source of the e-mail note, downloaded file, or diskette you've received is usually unaware that it contains a virus. Some viruses wreak their effect as soon as their code is executed; other viruses lie dormant until circumstances cause their code to be executed by the computer. Some viruses are benign or playful in intent and effect ("Happy Birthday, Ludwig!") and some can be quite harmful, erasing data or causing your hard disk to require reformatting. A virus that replicates itself by resending itself as an e-mail attachment or as part of a network message is known as a worm

Removing the infection

Removing the infection
The worms often schedule themselves to be run automatically when you start your operating system; some of them even register themselves to be run when any other application is started. Removing such a worm is not as simple as deleting it - when you just delete the worm file, your operating system might not be able to start your applications (such as Explorer) any more.
So, in order to properly remove the worm from your computer, it is often necessary to make additional fixes in your system registry, delete the links from your Startup Folder etc. Here the avast! Virus Cleaner comes - it will find and remove selected worms from your computer, as well as fix the registry and startup items to make sure your system will work correctly after the disinfection.
Many worms - when activated - create additional working files on your hard disk. Even though these files alone are harmless, they are useless and they should not be there. When avast! Virus Cleaner detects and removes a known worm from your computer, its working/temporary files are removed as well. The same applies for worm-specific registry entries etc.
