A számítástechnika is the study of computers and computational systems. It encompasses both hardware, which refers to the physical components of a computer, and software, which includes the programs and applications that run on these devices. This field plays a crucial role in various industries, enabling tasks such as data processing, communication, and automation. In addition to traditional computing, számítástechnika also covers areas like programozás (programming), adatbázisok (databases), and hálózatok (networks). Professionals in this field work to develop new technologies, improve existing systems, and solve complex problems using computational methods.
