2. INFORMATION TECHNOLOGY Information technology is a contemporary term that describes the combination of computer technology ( hardware and software) with telecommunications technology (data, image, and voice networks). 2

3. In some companies, this is referred to as Management Information Services (or MIS) or simply as Information Services (or IS). These innovations enable the processing and storage of enormous amounts of information, along with rapid distribution of information through communication networks IT has enabled the globalisation of the economy and competition, and caused large-scale changes in many industries IT is also bringing a major shift in the job market; resulting in a more polarised occupational structure, consisting of highly skilled = well paid jobs lower skilled = low wages 3

4. Communication : Basic need for most human activities Tarditional - telephone, fax, mail... In the new information era- e-mail, internet, video conferencing The new communication technology enables people located in different places to work together as if they were in the same office. Big multinational companies are already exploiting this technology to achieve better use of the resources of their seperate offices. In this way projects can be shared between offices with the application of the best expertise, and around the clock 4

6. Computer Use The purpose of a computer is to process data into information Data consist of the raw facts and figures that are processed into information Information is data that has been summarized or otherwise manipulated for use in desicion making Hardware and Software Hardware consist of all the machinery and equipment in a computer system Software , or programs , consist of all the electronic instructions that tell the computer how to perform a task 6

7. Hardware and software revolution The diminishing cost of personal computers has put computing power within the reach of even the smallest contractors. Rapidly developing hardware performance, coupled with the development of storage drives with very large volumes, modems, scanners, and back up devices has made the computer suitable for storage and distribution of drawings and other data in electronic format. The evolution of servers, network cards, modems and routers have linked computers together providing a forum for community collaboration . 7

8. Internet The value of the Internet to construction companies derives from its ability to easily connect globally to a vast amount of data, which would otherwise have taken more time and money to organise. By exploiting the resources of the Internet construction companies can gain the following benefits.   Acceleration in the distribution of knowledge resources within and out with the company Promotion and marketing for the company 8

9. On-line services : The rapid development of the Internet and the World Wide Web has enabled many services that traditionally required face to face meetings to be delivered on-line. Internet distance learning: opportunities of university education, widening access to higher education ( delivering teaching and learning to people who cannot attend lectures )-increases a country’s competitiveness in a global market. E-business: Internet provides a virtual market place for buyers, suppliers, distributors and sellers to exchange information, negotiate and trade Teleworking : Flexibility in working conditions, less office space, more productive workers. 9

11. History and Development of Information Technology In the 1960s and 1970s, the term information technology (IT) was a little known phrase that was used by those who worked in places like banks and hospitals to store information. With the paradigm shift to computing technology and "paperless" workplaces, information technology has come to be a household phrase. It defines an industry that uses computers, networking, software programming, and other equipment and processes to store, process, transmit, and protect information . 11

12. Software development  and  computer programming  were best left to the computer scientists and mathematical engineers, due to their complicated nature. As time passed and technology advanced, such as with the advent of the personal computer in the 1980s and its everyday use in the home and the workplace, the world moved into the information age. 12

13. Modern Technology By the early 21st century, nearly every child in the Western world, and many in other parts of the world, knew how to use a personal computer. Businesses' information technology departments have gone from using storage tapes created by a single computer operator to interconnected networks of employee workstations that store information in a server farm, often somewhere away from the main business site. 13

14. Technology facilitate our life Technology and information may be regarded as two things are mutually binding. Both support functions that are fairly similar. Advances in technology are always facilitate the delivery of information. The rate information from one country can spread rapidly to other countries, even to all countries, through increasingly sophisticated technology. Advances in information technology provide enormous benefit in human survival. Information technology can provide facilities in various aspects of life. One area of ​​life that has a close relationship with the use of information technology is the world of work. 14

15. Impact of Advanced Information Technology Advances in information technology is to be grateful and appreciated as a remarkable achievement. Therefore, we must take advantage of advances in information technology is to do positive things . Why is that ? In fact, advances in information technology not only provides a positive effect. Many also brought along the negative impact of information technology advances. 15

16. Here's a positive impact of information technology development. Make it easier for companies or individual business transaction-based information technology or so-called E-Commerce. Simplify access to information needed for various purposes. 16

17. Besides positive impacts, advances in information technology have a negative effect . The rapid advancement in information technology, internet and other media, facilitate the entry of banned sites and violence. Ease of transactions via the Internet will provide opportunities to perform transacts forbidden, such as drug and contraband transactions. As a result , anything that is required is completed in quick time to be done by utilizing flash technology as well. Finally, human life can not be separated from the flow of information technology. 17

18. The Role of IT It is accepted that telecommunication is a basic infrastructure necessary for economic and social development of a country. This is even becoming more strong than ever as information related economic activities are growing. Information and communications technology may be described as the support of the central nervous system of complex societies, transmitting and processing information and commands among the various parts of such societies. Internet plays a fundamental function in IT role 18

19. Benefits from IT Information and communications technology carries on high promise both in human and economic terms. Benefits could be obtained in: Education Job training Health care Food security Environment management Government efficiency 19

20. IT is useful in all areas Many tourism businesses are involved in developing their internet services including traditional travel agents , tour operators , national tourist offices, airlines , hotels and other accommodation providers and car hire firms. 20
