The campus net is take the computer as a foundation,
serves to the teaching scientific research, the administration and
inside and outside correspondence and so on three big goals computer
local area network winds. He through to world in massive
knowledge information picking
The collection, the analysis, the reorganization, and
regards, the audio frequency and the writing, the multi-dimensional
picture and so on alone or the synthesis manifestation and the
technique, applies to the school teaching. Thus changed the past
mainly to depend upon the student abstract thinking primarily passive
form educational model. Computer network introduction elementary
and middle schools campus, not only the massive information storage,
will transmit for the teacher and the elementary and middle school
students, improved the teacher teaching method, enhanced the teacher
teaching efficiency and the teaching quality, what will be main will
be through the network, will train the teacher and the student from
on-line gathering, the analysis and the processing massive information
ability, thus greatly enhanced the student to study the quality, met
the 21st century information time need.
[ System principle >
The campus net network system is basic may divide into
the campus hub, teach the scholar the net, manages the son net, the
books inn net, the dormitory area sub- net, the rear service sub-
network and the original wired television network's transformation
turns on the net and so on.
The campus net construction, should follow the system the
usability, extended, the reliable three big principles:
1st, usability:
The education is by invests the primarily profession.
Relatively says, is in the developing nation our country, the
economy insufficiently developed, causes the education funds to be
short and origin sole. Therefore, the campus net construction
should fully consider the concrete school the present situation,
construction both economy and practical campus net.
2nd, extension:
The computer technology unceasing consummation and the
application scope unceasing expansion, can cause its unceasing
promotion and the renewal. Therefore, constructs when the
concrete campus net, to the foundation and a host partial construction
and the disposition, should have foresightedness; To the
terminal construction, should remain has the expandable leeway, in
order to has the continuous nature to the entire campus net
construction which may develop.
3rd, reliability:
The school is only the campus net user, is not unnecessary also
with difficulty to provide for network engineer. Therefore, in
concrete construction time, must consider the campus net the
usability, the easy maintenance and the reliability.
Because of this, the high performance, may expand, is easy
promote, economical practical "EVOC the" industry level computer,
becomes constructs the campus network system most competitive hardware
platform.

[ System appraisal >
1st, the system uses reliable extremely high "EVOC the"
industry level computer, the use is simple, maintains easily, while
full guarantee system secure, certainly does not need specially to
suppose network engineer to carry on the management;
2nd, may choose the ledger wall type, may promote the industry
motherboard, enables the overall system to have the nimble extension,
slightly makes the change in view of the different school special
details to the system disposition then; |
