ict is the abbreviation of information and communication technology.
ICT (information and communications technology) is an all-encompassing term, covering all communication devices or application software: for example, radios, televisions, mobile phones, computers, network hardware and software, satellite systems, and so on; And related services and application software, such as video conferencing and distance learning.
this term is often used in a specific field, such as information and communication technology in education, information and communication technology in health care, information and communication technology in libraries and so on. This term is more commonly used outside the United States.
the European union believes that information and communication technology (ICT) is not only technically important, but also more important for economically backward countries to have more opportunities to access advanced information and communication technology.
Many countries in the world have established organizations to promote information and communication technology, because people are afraid that with the development of information technology, the economic gap between developed countries with information technology and underdeveloped countries without information technology will widen if backward countries do not seize the opportunity to catch up. The United Nations is promoting the development plan of information and communication technology on a global scale to bridge the information gap between countries.
Evolution of information and communication technology
Human communication has a long history, from ancient beacon towers to modern multimedia communication, at least thousands of years. The revolutionary change of human communication took place after electricity was used as the information carrier, and its remarkable signs were Morse's invention of telegraph in 1844 and Bell's patent for telephone invention in 1876.
in p>1946, the world's first general-purpose electronic computer came out, and the development of computer technology went through four stages, namely, the mainframe era from 195s to 198s, the minicomputer era in 198s, the PC era in 199s, and the network era starting in the mid-199s.
it is the mutual penetration and integration of computer technology and communication technology that has brought mankind into a brand-new era-ICT era. Today, ICT has been widely integrated into human economic and social life. With the continuous expansion of ICT applications, ICT is not only limited to information and communication technology itself, but also includes consumer electronics, technology and its related services.
