Technology's central role in our lives has drawn concerns and backlash. The backlash against technology is not a uniform movement and encompasses many heterogeneous ideologies. The earliest known revolt against technology was Luddism, a pushback against early automation in textile production.
Technology ethics is the application of ethical thinking to the growing concerns of technology as new technologies continue to rise in prominence. The topic has evolved as technologies have developed. Technology poses an ethical dilemma on producers and consumers alike.
Negative effects on the environment. The effects of technology on the environment are both obvious and subtle. The more obvious effects include the depletion of nonrenewable natural resources (such as petroleum, coal, ores), and the added pollution of air, water, and land.
Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users ...
Disadvantages of e-mail: the presence of such a phenomenon as spam (massive advertising and viral mailings); the theoretical impossibility of guaranteed delivery of a particular letter; possible delays in message delivery (up to several days); limits on the size of one message and on the total size of messages in the mailbox (personal for users).
Technology transfer aims to ensure that scientific and technological developments are accessible to a wider range of users who can then further develop and exploit the technology into new products, processes, applications, materials, or services.
Disadvantages of this form of educational technology are readily apparent: image and sound quality are often grainy or pixelated; videoconferencing requires setting up a type of mini-television studio within the museum for broadcast; space becomes an issue; and specialized equipment is required for both the provider and the participant.
Social construction of technology (SCOT) is a theory within the field of science and technology studies. Advocates of SCOT—that is, social constructivists —argue that technology does not determine human action, but that rather, human action shapes technology.
Since technology has evolved in the past ten years or so, companies are beginning to converge technologies to create demand for new products. This includes phone companies integrating 3G and 4G on their phones.
The protocol suite does not explicitly specify hardware methods to transfer bits, or protocols to manage such hardware, but assumes that appropriate technology is available. Examples of that technology include Wi-Fi, Ethernet, and DSL.
