What is different between novell network and Microsoft network?
The primary difference is that when using a workstation as a Novell client, you're most likely connecting to a Novell network, and when using one as a Microsoft Client, you're most likely connecting to a Microsoft network.
Novell and Microsoft's models of network security differ. Microsoft has their Active Directory (which arguably a lot of which has been stolen from Novell), and Novell has their NDS (Novell Directory Services).
In terms of your computer connecting to one of these networks, it'll differ between a Novell and Windows network in some technical ways, but from a user's perspective things remain pretty similar.

Patches are typically small updates to some software that either fix a security flaw or another functional flaw in part of the software. They are usually one or a few files that are changed to fix the flaw by replacing older versions of these files. Another kind of much larger patch is called a service pack and this usually is just a wrapping together of the changes that were previously made by smaller patches into a larger package. Software products exist to manage the patching process on larger groups of machines for network administrators. These products typically try to focus their "patch coverage" on the most commonly exploited (for the security flaws patches) or used products that require patches on these networks, most commonly for Windows networks. Patch coverage is related to the number of products patched by the management software.
What are the things to be monitored on a network?
Each device will have different requirements, and even then, you'll need to decide what you want to monitor and why. Are you interested in disk space? CPU utilization? Do you want to make sure that a certain application or service is running on a device? The more complex network monitoring solutions can do just that, and anything else your mind can dream up.
