It
is
very
insecure
if
we
are
talking
about
Internet
because
data
is
sent
unencrypted
since we don’t use any kind of encryption technology. Therefore, in order to send data
securely,
firewall
needs to be
implemented.
An
intranet
is
a
secure
network,
usually
corporate,
that
uses
Internet
technology
to
integrate desktop, work group, and enterprise computing into a cohesive framework.
2.1.7 Testing Phase
Testing
is
important during the completion of
a
system.
Testing
allows
the system to
be reviewed and repaired if there are any errors occurred before implementation.
2.1.7.1 Testing Definition
Testing is an important phase performed by a software developer in order to know the
system meets user requirements, any errors and bugs, any kind of recommendation, etc.
Testing shouldn’t be done after the whole program
has been
written or done after the
implementation
phase.
There
are
3
types
of
level
testing
to
be
performed:
stub
testing,
unit or program testing, and systems testing.
1. Stub testing is like testing one module or events of the entire program. It’s testing
of a subset of a program.
2. Unit or program testing is
testing
the entire program and
must be done after stub
testing is completed.
3. Systems
testing
are
testing
the
entire
program
by
using
a
real
data
and
must
be
performed after unit or program testing completed.
