魔力鸭的机械键盘:谁能帮我翻译一下这篇计算机文章(要人工翻译),谢谢!

A very brief conceptual introduction to time-sharing is not an easy task because the term

has already become so generalized that it has a great variety of meanings to scores of

interesting groups and wide ranges of intelligence levels in such groups.It might best be

developed by listing its logical components: simultaneity - a variable number of people can

use the computer at essentially the same time; independence - the programs being handled by

the system are operated independently of one another without risk of being intermixed or

having security breached; immediacy - all requests for computer response receive that

response within seconds (or less) of the completion of the required computation, and most

often before "action deadlines" occur; spatial unlimited ability - missiles millions of

miles away have operated in real-time; and earth-bound time-sharing users can communicate

with the computer by means of teletype, visual displays(cathode-ray tubes) and scores of

other input/output devices which are not generally in close proximity to the central

computer, and can be continent away .Time-sharing is really the utilization of time.
