Database
Support |
A
well-designed application will to some extent validate information
entered, but no system can check total accuracy. Thus whoever enters
data may be held responsible for its validity and accuracy, while
the IT team accepts responsibility for the data's integrity within
the database....... |
| Networks |
Network
exists to transfer data between the various components of a computer
system or, increasingly, between different computer systems. Networks
have existed in one form or another since the earliest days of commercial
computing....... |
| Ethernet
Overview |
Ethernet has been with us since 1980. Early Ethernet was carried
over stiff coax and later more malleable thin coax. Coax Ethernet
installations require that the cable be snaked past each network
device and that the device tap into the cable as it goes past...... |

This puts the quality of those systems fully under the spotlight
and shows that achieving quality in IT is much more than just a
technical issue......... |
| Risk
Analysis |
There
is no such thing as complete security. All that a company's managers
can do is to manage the various hazards to which they might be exposed
and thereby minimise the risks......
|
| Security |
Computer
security is thought of as a series of purely technical problems
to which a range of technical solutions can be applied. Most companies
that use IT soon become completely dependent on computers and change
their whole way of conducting business as result........ |
| Security
Measures |
A
proper security programme will depend on a combination of:
(a)
a means of preventing the occurrence
(b)
a means of timely detection of the occurrence
(c)
where possible, some form of defence (eg anti-virus software)
(d)
a means of recovery....... |
| Standards |
As
in any industry, the need to have standards in the IT industry is
vital. Standards provide the IT or purchasing manager with:
(a)
a method of comparing the price of like pieces
of equipment that meet the same standard; this ensures equipment
has the same technical specification
(b) confidence
in the safe operation of equipment with regard to electrical insulation,
