What is Digital Technology?

What do you imagine when you hear the term digital technology (teknoloji digital)? Surely objects that are already familiar, such as computers and all their supporting devices. Apparently, this is not quite right considering the computer is only one result of digital technology. So what exactly is the meaning of digital technology itself?

Digital technology is a technology whose operating system runs automatically using a computerized system. Basically digital technology is just a very fast counting system that processes all forms of information as numeric values ​​or digital codes.

The emergence of digital technology at the end of the decade of the 70s marked a technological revolution. The term digital itself is an antonym or opposite of the term analog. Where, digital technology is a form of development of analog technology, but it is different from that technology. Digital technology does not store data or information in the form of images and sound.

While data storage is the process of storing data in a computer or a hard disk, flash disk, CD and others with the aim of keeping the data from being lost when it is opened and processed again in the future.

Basically digital technology processes all forms of information as numeric values ​​so that they can be read by computers. One example is a cellular telephone, where when calling a digit is sent to a recipient somewhere using radio waves. The recipient’s phone then again converts the received numbers into a voice that can be heard by the recipient.

Data Transmission

Data transmission is a process of sending data from a data source to a data recipient using computer or electronic media. As for the data transmission, there are several important parts contained in it, namely signals and modulation, data transmission media, data transmission directions, and data transmission modes.

  • Signals and Modulation are electromagnetic waves used to transmit data or information from one place to another. Signals are grouped into two, namely analog signals and digital signals. While modulation is the merging of data signals and carrier signals to transmit information with the aim of efficiency and minimizing noise.
  • Data Transmission Media, is the media used to transmit data so that it can connect the sender with the recipient of the data. The data transmission media is in the form of Guided Transmission Media which uses a cable system and Unguided Transmission Media which uses an electromagnetic wave system.
  • Direction of Data Transmission, is a process that explains how the direction of data transmission contact that occurs between the sender and receiver of data. The direction of data transmission is divided into three, namely simplex, half duplex, and full duplex.
  • Transmission Mode, is a process or method in transmitting data from a medium or device to another medium or device. This transmission mode affects the number of transmission media paths used. Transmission mode is divided into two, namely serial transmission and parallel transmission.

Applications of Digital Technology in Daily Life

Digital technology has been widely applied in everyday life, where its existence acts as a medium or tool for activities in various fields such as in the fields of research, education, business, social, and so on.

Some of the applications that are often used here and are familiar in everyday life are cell phones, CDs for data storage, computers, and so on.
