IT

(Information Technology) Processing information by computer. IT is the latest moniker for the industry as a whole, and the term became popular in the 1990s. It actually took 40 years before the industry settled on what to call itself. First it was "electronic data processing" (EDP), followed by "management information systems" (MIS) and "information systems" (IS) and finally "information technology" (IT).

IT Versus OT
Contrast information technology with "operations technology" (OT), which uses computers to control machines in manufacturing and other industrial applications. IT handles the business information derived from the products made by OT. IT and OT systems may be highly integrated or have minimal or no integration. See Internet of Things, process control and PLC.

Networking and Often Voice
IT includes networking but may exclude telephone service. Increasingly however, voice is based on the same IP networks as the company's computers, and telecom has become part of the IT world rather than an entirely separate department. See information system and enterprise networking.

Thought was then free only in this manner; hence it never wrote itself out completely except on the books called edifices.
There was nothing down to poor poetry,--properly speaking, that which persisted in vegetating in manuscripts,--which was not forced, in order to make something of itself, to come and frame itself in the edifice in the shape of a hymn or of prose; the same part, after all, which the tragedies of AEschylus had played in the sacerdotal festivals of Greece; Genesis, in the temple of Solomon.
And so without particularly analyzing all the contiguous sections of a cone and of the ranks of an army, or the ranks and positions in any administrative or public business whatever from the lowest to the highest, we see a law by which men, to take associated action, combine in such relations that the more directly they participate in performing the action the less they can command and the more numerous they are, while the less their direct participation in the action itself, the more they command and the fewer of them there are; rising in this way from the lowest ranks to the man at the top, who takes the least direct share in the action and directs his activity chiefly to commanding.
Restoring the essential condition of relation between those who command and those who execute, we find that by the very nature of the case those who command take the smallest part in the action itself and that their activity is exclusively directed to commanding.
Among the beds of lilies I Have sought it oft where it should lie, Yet could not, till itself would rise, Find it, although before mine eyes.
I wished to observe the different forms taken by the irritation that I should naturally produce; for it is under the influence of irritation that the French character most completely expresses itself.
Thinking over what he would say, he somewhat regretted that he should have to use his time and mental powers for domestic consumption, with so little to show for it, but, in spite of that, the form and contents of the speech before him shaped itself as clearly and distinctly in his head as a ministerial report.
Far and deep in its own region, busying itself, with preternatural activity, to marshal a procession of stately thoughts that were soon to issue thence; and so he saw nothing, heard nothing, knew nothing of what was around him; but the spiritual element took up the feeble frame and carried it along, unconscious of the burden, and converting it to spirit like itself.
So, year after year, Silas Marner had lived in this solitude, his guineas rising in the iron pot, and his life narrowing and hardening itself more and more into a mere pulsation of desire and satisfaction that had no relation to any other being.
Thus, in respect of the manner in which the thing takes place, it is the peculiar mark of substance that it should be capable of admitting contrary qualities; for it is by itself changing that it does so.
It is high time that Communists should openly, in the face of the whole world, publish their views, their aims, their tendencies, and meet this nursery tale of the Spectre of Communism with a Manifesto of the party itself.
See how the deep divine thought reduces centuries and millenniums and makes itself present through all ages.
