Role of Information Technology

The role of information technology today, seems to have very inherent in human life. Starting from interacting, reading news, deals, and more. In fact, information technology became a major facilitator for business activities.

In addition, information technology also contributes greatly to the fundamental changes to the structure, operation, and management of an organization.
Advances in information technology make high investments bold entrepreneurs in the field of information technology, the most common reason is the need to maintain and enhance its competitive position, reduce costs, and increase flexibility.

With the information technology, the convenience can be felt by humans. For instance in making money through the ATM (Automated Teller Machine). In addition, you can perform transactions over the Internet are dkenal with e-commerce (electronic commerce).

In education, the development of information technology to make the transformation of science learning faster and easier. Information technology can transform rural economy to be better in agriculture, plantations, and farms.

Can not be denied again, the advent of technology brought many influences in the lives of people in various fields, such as economics, social, political, cultural, defense, security, and others. Thus, the presence of information technology in human life make the most of information technology to meet human needs.

So it can be concluded that in general the role of information technology are as follows.

Information technology replacing human role, that automate a process or a human task.

Strengthen the role of human technology, by providing information to a task or process.

Information technology plays a role in the restructuring of the human role in making these changes and the task.

Information Technology Systems

The term IT (information technology) that is popular today is part of a chain of long term developments in the world of SI (System Information). An information technology system is basically built on five levels in a pyramid of STI (Information Technology Systems). Depth is a question of basic concepts, technologies, applications, development, and management.

Information technology system is a system that is formed in relation to the use of information technology. Component of the information technology system was 3, which hadware (hardware), software (software), and brainware (human).

In the information technology systems, both complex and simple, the goal is to produce the information. An existing information systems information technology can be said to be useful if sustained by three things right on their needs (relevant), just in time (timeliness), and the exact value (accurate). If the information in the information technology systems are not supported by the third case, the information in it is useless.

In general, the information on the STI (Information Technology Systems) is divided into 3 types. The breakdown is as follows.
1. Information Data Collection

This information is information that takes the form of accumulation (data collection) to answer questions. Within an organization, this information is very useful for lower-level managers to evaluate the performance of its employees.
2. Steering Information Caution

This information is information that is used to focus attention on issues that deviate, inefficiency, or irregularities. Deviation here can be over-budget costs, which have not achieved the sales target, the company’s revenue decline, increased production costs, and others.
3. Troubleshooting Information

This information is information that helps decision-makers to solve the problems being faced. Problems here are the problems that require repeated analysis of the top-level management.

Development of Information Technology

Actually, since the first humans are familiar with the technology. But, of course, the existing technology used to be much different than today’s technology. For instance typewriters, ancient machine is used to assist people in creating documents. More advanced age makes typewriters are not used anymore.

Today, people have more sophisticated technology to make the documents, the computer. The use of computers not only enable people to create documents, but in the finish ‘the job’.

In addition, the first people still send letters using couriers and require a long time. Meanwhile, today people are able to send mail via telegraph. Even now, with the invention of computers and the internet, people can also send a letter via e-mail in seconds.

Later, after Alexander Gragam Bell managed to find the phone, people are able to communicate with each other even though the distance is very far. It is proved that the development of information technology develops very rapidly.

Currently, the development of information and technology make people can already make a robot, for example, the household robot (like a vacuum cleaner), robot dogs and others. All the robot was created to enable people to get the job done. It is possible, sometime in the work of man can be replaced by robots. The robot will work automatically and corrects errors by itself.

It could be concluded that the development of information technology is more advanced and rapidly than in the past. Predictably, the 21st century will appear technologically advanced and beneficial to humans.

Information Technology

Information technology is derived from the Latin ‘texere’ which means to build. Basically, the technology has two important aspects, namely the software (software) and hardware (hardware). Information technology is not far away from the life-world development technology itself.

Both components (hardware and software) are related to each other, working together to create an information technology. However, it looks more dominant technology in hardware (hardware). Even so, the software (software) also has a very important role.

Information technology is a technology that serves to process data (process, obtain, compile, store and manipulate data) in various ways, so as to produce quality information. In this case, the required information must be relevant and accurate. In addition, the information is useful for personal, business, and government.

Information technology is often associated with communication technology. This is because the software and hardware is interconnected with one another. Basically, information technology and communication technology have the same definition. Communications technology means all information technology that supports all communication technologies.

No wonder, if this time comes the term ICT (Information and Communication Technology). ICT is an evidence of the merging of two aspects: information technology and communication technology. This term appears, after the combination of information technology and communications technology in the 20th century.
