Currently, the development of communication networks has influenced how humans communicate and exchange information. Data communications technology reflects the rapid evolution in the way humans communicate and exchange information. Data communication is the process of exchanging information between two or more devices via a transmission medium, such as cables, radio waves, or other network infrastructure. The goal of data communications is to transfer data from one location to another quickly, efficiently, and accurately. The method used is to look for references from several internet sources such as Google. The OSI model has 7 layers, namely Application Layer, Presentation layer, Session Layer, Transport layer, Network layer, data link layer, physical layer

The development of the world of telecommunications continues to improve. Its initial appearance was as first generation technology (1G) which still uses the same system. In 1991, 2G technology began to develop, using a digital system and being able to provide not only voice services but also data services. This technological development was then followed by 3G and 4G. Currently, technological progress has increased very rapidly in almost every field of technology. has created very sophisticated tools to support human work. One of the latest technological advances that plays an important role is the emergence of 5G technology. 5G technology is a wireless technology that is more complex than previous wireless technologies. With greater bandwidth, higher data speeds and lower latency, this technology can provide opportunities and benefits for operators to create new business models.

Abstract. Input/output (I/O) technology plays an important role in the development of modern computer hardware and software. The rapid development of I/O technology has allowed computers to become more interactive, faster, and more efficient in processing information. In the I/O process, there are hardware and software that function as a medium to produce data. Hardware and software are interrelated and support each other in computer operations. This study aims to analyze the role of I/O technology in hardware and software based on its development. I/O technology refers to the way a computer interacts with the outside world through inputs and outputs. Data is obtained based on literature studies using references from various sources. This research method aims to understand the existing framework of knowledge about judu, identify and support or detail arguments. Based on existing literature, the results show the role of I/O technology in hardware and software is very influential on its development can be seen from better hardware performance, innovation in hardware that continues to develop and more advanced software developments.
