MANAGEMENT CONCEPT OF HIGHER EDUCATION SYSTEM
The Computerisation and Information Technology on various walks of life, has made a significant impact and greatly contributed to the development of industry in general. Equally important now is
its growing influence on the working and functioning of various government and private organizations. Management of higher education can not escape this impact. In fact, the university system is keen to lend itself to the adoption of computerisation. However, the impact still is a far cry, either because of certain vested interests or lack of motivation on the part of management, or both. Never the less it has already spread its wings and the onslaught is on. The question remains how and when one should do the beginning. On one had there is considerable progress and enthusiasm in adopting the new information technology (IT), but a proper timing and process of selection has to be thought besides enough financial resources and willing manpower to take the challenge. The only
other part remaining would be the proper selection of hardware and software packages.
However,before one would like to select the Grey areas of its influence in the university management, it may be appropriate to briefly outline the problems and issues of the university management in general and then pinpoint the areas where an effective and concentrated beginning could be made.
Identification of such issues will definitely help in its implications.
Broadly the higher education system, namely the University Administration has the following two dimensions:
- Academic related and or Institutional Administration that keeps the system greased and going e.g. the management, the controls, the establishments, the accounting, the security and the over all upkeep.
- Pure Academics - the syllabus, the teaching techniques and methodology, together with evaluation and examination system.

INFORMATION TECHNOLOGY IN HIGHER EDUCATION THE NEED
- to develop a data bank
- to update the data bank
- to provide information on finger tips
- to be transparent and accessible
- help the administration to be efficient, economic and less time consuming
- to link various departments/sections/divisions and units and help
- in better coordination/evaluation and accountability for disposal of papers
1. How quick is the response to queries?
2. How quick is the disposal of cases?
3. How efficient are the mechanisms?
To illustrate the impact of IT and Computerization, we have a few examples of common day use like railway reservations, air travel reservations, banking systems particularly ATM and national and international Communication systems as a whole.
Therefore, if these systems have shown the improvement why not to adopt these systems in the university management as well, and make the system more functional, efficient and informative.

CAD and graphics
applications are characterized by loading large files. In this case the access
time of the drive isn’t as critical as the transfer rate. A 40ms or 28ms drive
would certainly be adequate, but the drive should be an ESDI drive and if possible
should be used with a caching disk controller. A disk cache, software or
hardware based, will usually speed up disk operations in a CAD/graphics system
more than the same amount spent on a better quality disk drive. In a budget
system an ST-506 controller could be used successfully but a 1:1 interleave is
desirable.
The final
element is of course the graphics adapter. The type of graphics adapter needed
depends on the nature of your application. If you can avoid using colour then
the speed of any graphics operating will be much higher. Indeed there is an
argument for using monochrome for any stage in the application for which colour
isn’t essential and then switching to colour for finishing. The minimum
graphics standard needed for CAD/graphics is VGA or Super VGA. The main problem
here is in getting the speed needed to redraw the screen in a time that makes
interactive graphics interactive. A better solution is to use an intelligent
graphics adapter either based on TIGA or 851/A and even here an MCA or EISA bus
would still be an advantage.
Intel have
introduced a special version of the 386 and 387 co-processor-the Rapid CAD chip
set-optimised for graphics. Benchmarks show that replacing a 386/387 pair by
Rapid CAD chips halves the time it takes to render a complex image. For simple
images the speed gain is much less. Another way to look at this is that
RapidCAD converts a 25MHz 386 into the equivalent of a 33MHz machine and 33MHz
into a 25MHz 486. Rapid CAD can be fitted without any modifications to the
machine.

The detailed
specification of a CAD/graphics machine depends very much on the exact software
that you are using, but the general nature of the machine is very clear. The
high use of the CPU and co-processor (as long as the software supports it)
suggests that a 486 is the best choice. Memory requirements suggest that 4
MBytes of extended memory is a reasonable allocation, although programs such as
AutoCAD can put up to 16 MBytes of extended memory to good use. The motto seems
to be the more the better apd so for a CAD/graphics machine it is important to
check the maximum amount of memory that can be installed on the mainboard or
using expansion cards without loss of speed.

displayed and then the second half frame is displayed shifted so that its lines fit between the lines of
the first frame. This is called
interlace and it succeeds in lowering
the frame rate without increasing the
flicker – it is used quit successfully,
for example in broadcast TV pictures.
Unfortunately, as far
as computer video goes its effects are very poor. Because of the way that
computer graphics often use alternate lines, or patterns of lines to make
intermediate shades or colourss,
this use of interlace often produces a strong and very noticeable flashing. It is possible to arrange a demonstration of interlaced video
so that it looks acceptable by avoiding tones or colourss that use regular odd/even line patterns.
Equally, it is possible to find displays that
make and interlaced Super VGA is
tolerable as long as you avoid
even grey tones. Some applications
packages are even altering there colours scheme to avoid flicker on interlaced systems – Ventura 4 for
instance gives the user the option of
changing the grey surround
to an even colours to reduce
flicker.
Some Super VGA boards support non-interlaced monitors and
even increased vertical scan rates
up to 70Hz. Changing to a non-interlaced monitor makes the biggest
difference but a scan rate of 70Hz is
also worthwhile. Notice that to make use of non-interlaced high scan rate modes you need a video card and monitor that
supports them.
