Test documentation normally is included
with the software during packaging. Vendor patches, fixes, and
upgrades usually occur after the product has been purchased. Vendors
provide patches and updates of their products when bugs are found in
their software or to make their software run more efficiently. In the
case where a bug is found in an earlier release, patches are provided
to fix the bugs. The most current patch or fix is likely to be found
on a vendor's web page. Normally, a search feature or online support
guide on the vendor's web page is available to easily navigate the site
to locate the specific patch needed.
Software upgrades are designed to improve and make current software more powerful. Normally, upgrades are free (or can be purchased for a fee) and can be downloaded from a vendor's webpage in the same way as a patch would be downloaded.
However, a backup should be made before installation to prevent loss
of data.
Without anti-virus software installed
on the servers and workstations, no modern network will continue
working efficiently. Depending on the users needs, a wide variety of
anti-viral packages are available. An ongoing network maintenance
strategy should be to update virus signatures frequently; because new
viruses are spawned frequently, within a few months, what was
previously protective anti-virus software can become useless.
