INTRODUCTION

            

ICT (Information and Communication Technology) is a broad term that refers to all technologies and services related to computing, data processing, telecommunications, and the internet. All of these systems are concerned with the transmission and reception of data in some way. It allows people to communicate in different way, making it  easier, and faster for people to connect, engage, seek support, learn, and obtain access to information through the use of computers, electronic devices, and software programs to encode, store, encrypt, process, distribute, and retrieve data from anywhere, at any time.

ICT (Information and Communication Technology) is an effective instrument that can be used to boost the country's economic growth. As it can be used as a learning and education medium, as well as a mass communication form of media for advocating and campaigning on practical and significant topics such as healthcare and personal issues, it can increase the quality of human life. It gives you a broader understanding and can assist you in obtaining and accessing information. Though we are still struggling to make successful use of ICT in an area where other countries have already gotten ahead of us.

SIGNIFICANCE OF ICT IN THE SOCIETY

 

         Our world continuously evolve and becomes more and more modern everyday. With its new technologies and advances, ICT play a significant role in our everyday lives. It has huge impact to the society and its future. Information and Communications Technology (ICT) has the power to transform society and and it is an important enabler of change. It changed the way we communicate with each other, how we find information and how we manage our social lives. ICT affects almost every aspect of 21st century life, from transport efficiency and safety, to access to food and healthcare, socialization and productivity. The power of the internet has enabled global communities to form ideas and share resources more easily.

         People have incorporated ICT into their everyday lives, such as using cell phones to make calls, withdrawing cash out of the ATM, or using the computer to browse the internet. It affect all aspects of life by providing newer, better, and quicker ways for people to interact, network, seek help, gain access to information, and learn.  Our society has become more accustomed to having the benefits of ICT, which has changed the way people live and interact with one another.

HISTORY OF ICT

PRE-HISTORIC PERIOD

At first humans developed information technology at this time serves as a system for the introduction of the forms that they know. They describe the information they get on the walls of the cave, about hunting and prey animals. At this time they began to identify objects that exist in the environment they live and represent it with the forms which they then painted on cave walls tempa.t they live, because of their ability to speak only about the form of voice grunts and hand gestures as a form of their initial communication at this time. Further development is created and use the tools that generate sounds and cues, such as drums, trumpets made of animal horn, or smoke signals as a means of giving warning of danger.

HISTORICAL PERIOD

2900 BC

The use of letters hierogliph on the ancient Egyptians. Hierogliph a language of symbols where each phrase is represented by different symbols. When combined into one will have a way of pronunciation and different meanings. Heirogliph form of writing and language is more advanced than Sumerian writing.

500 BC

Papyrus fibers are used as paper. Paper made from papyrus tree fiber that grows around the Nile is a medium for writing or media information that is more powerful and flexible than the clay tablets that were previously used as a medium of information.

1995

Public enterprises began to be allowed into the provider by purchasing network in this Backbone.Langkah began development of information technology especially the internet and research to develop systems and more sophisticated tools.

Negative Impacts of ICT to the Society

NEGATIVE IMPACTS OF ICT

Loss of Jobs

One of the largest negative effects of ICT can be the loss of  a person's job. this has both economic consequences, loss of income, and sociel consequences, loss of status and self-esteem. Job losses may occur for some reasons, including: Manual operations being replaced by automation. e.g. robots replacing people on an asesmbly line.

Reduced Personal Interaction

Being able to work form home is usually regarded as being a positive effect of using ICT, but tgere can be negative aspects as well. Most people need some form of social interctaion if they do not get the chance to meet and talk with other people they may feel isolated and unhappy.

Health Problems

A computer may harm the users if tey use it for a long hours. Computer users are also exposed to bad posture, eyestrain, physical and mental health.

Reduced Physical Activity

Users may adopt a more sedentary lifestyle. This can lead to health problems such as obesity, heart disease and diabetes.

POSITIVE IMPACTS OF ICT TO THE SOCIETY

EXAMPLES OF ICT TOOLS

LAPTOPS

Laptops, also known as notebooks and portable PCs, are electronic devices that include a monitor, keyboard, processor, memory, hard drive, and cursor-positioning system, such as a touchpad or trackpad, all in one unit and are powered by a battery.

TABLETS

Tablets are ultraportable laptops that are smaller than regular laptops. Tablets are usually less expensive than brand new laptops, but their processors and other components are less efficient. Instead of physical keyboards, tablets have virtual keyboards or use a digital pen.

SMARTPHONES

The storage on these hand devices is provided by flash memory rather than a hard drive. It has touch-screen technology and virtual keyboards. Smartphones are small and compact, with varying battery life; you can access data and information as long as you have an internet connection. It can also take photos, navigate the roads, set alarms, making calls and sending and receiving short messages.

ATM

ATMs are automated teller machines that allow customers to withdraw and deposit money, pay bills, and apply for loans without having to visit a bank branch. ATMs are referred to as dedicated machines because they are only equipped to perform banking functions.

SERVERS

Servers are used to manage networks, provide access to specific files, host websites, and process large quantitiess of data. Not at all portable, since they are connected to each other in a network. Removing one means that it is no longer functions as a server.

EMBEDDED COMPUTERS

Embedded computers are devices that are designed to serve a specific function, such as waking you up in the morning, controlling the temperature of your air conditioning or refrigerator, or managing the navigation system.
