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.
