1. Understanding IT (Information Technology)

Information Technology, or more commonly known as IT, is the heart of today's digital world, encompassing everything from computers and hardware to software and interconnected networks.

According to Bambang Warsita, IT is not just a tool, but a sophisticated system for processing and utilizing data in a meaningful way.

Meanwhile, Hamzah B. Uno and Nina Lamatenggo emphasize that IT is a technology that supports the processing of data into relevant, accurate, and timely quality information.

Interestingly, IT is not limited to personal computers; it also encompasses various modern devices such as smartphones, tablets, and smart TVs, which have now become an inseparable part of our daily lives.

2. History of IT Development

The history of Information Technology (IT) began in the pre-computer era, where communication was conducted orally and in writing, followed by the invention of the alphabet and numbers.

The invention of the printing press by Johannes Gutenberg in the 15th century was revolutionary in the dissemination of information. Subsequently, the inventions of the telegraph, telephone, radio, and television in the 19th and early 20th centuries accelerated the flow of information.

The mid-20th century saw the birth of computers, with ENIAC as a pioneer. The development of the internet began in the 1960s with ARPANET, which evolved into a global network.

Today, the mobile and cloud era is changing the way we access information, enabling connectivity anytime and anywhere, with continuously increasing computing and telecommunications capacity, creating unimaginable new opportunities.

3. The Important Role of IT in Various Fields

Information Technology (IT) has become a key pillar in the transformation of daily life and the business world. IT enhances efficiency and productivity through process automation, ERP systems, and better communication with platforms like Slack and Microsoft Teams.

Access to information has become faster thanks to the internet, supporting learning and research. Product and service innovations, such as streaming applications and ride-sharing, are changing the way we interact and transport ourselves.

Additionally, data analysis supported by IT helps companies make better strategic decisions. Overall, IT is the key to unlocking unlimited potential in the modern era.

4. Main Functions of IT

To understand the world of IT, we need to recognize its six main functions:

1. Capturing: Collecting data through devices such as keyboards and sensors, for example, POS systems that record transactions in real-time.
2. Processing: Transforming raw data into valuable information through analysis, as done by CRM systems to understand customer behavior.
3. Generating: Presenting information in the form of reports and graphs that are easy to understand, such as business dashboards displaying KPIs.
4. Storage: Ensuring the security of data storage across various media, from hard drives to the cloud.
5. Retrieval: Facilitating the quick discovery of stored information through database management systems.
6. Transmission: Enabling the sending of data between locations via networks, using applications like email and video conferencing.

Understanding these functions helps us appreciate the role of IT in everyday life.

5. Main Components of IT

To understand the world of IT, we need to explore five main components that complement each other:

1. Hardware: Physical components such as computers and servers for storing data.

2. Software: Operating systems and applications that manage daily tasks.

3. Networking: Enables communication between devices through infrastructure and protocols.

4. Database: Stores information in an organized manner and facilitates data management.

5. Human Resources (Brainware): Professionals who manage and ensure that systems function well and efficiently.
