TODAY WAS OUR PRESENTATION
We followed our presentation closely and during this time all went smoothly. Mr Siva commented that Firdaus was speaking too fast as if he was nervous and he could do better.
During the Q&A session, we couldn't answer to Mr Siva what a router and a switch does. Thus we were both left stuck.
In the next question regarding WHAT WAS THE PURPOSE OF SETTING UP A VIRTUAL MACHINE FOR, we couldn't answer accordingly and Terence tried answering but gave the wrong replied.
Can you do a research and find out the answer for the questions posted during your presentation? I might be asked again :)

I find the best way to tell people what a router or switch does is to relate it to the road transport system. For example, a router can be seen as a miniature version of the road transport system as it can control which direction traffic is allowed to go. To better understand this picture a road with lots of streets, avenues etc branching from it, these can be imagined (in terms of the router) as the allowed directions that traffic can flow because nothing is restricting access. However, put a road block at one of those streets and traffic is now unable to flow through there. This can be related to adding a firewall rule to your router to restrict access. I hope this helps anyone trying to explain this concept to non-technical staff/people.
ReplyDeleteCommenting on the virtualization part. When is virtualization not a good idea? When high cpu usage is likely to occur. This is about the only "WORTHY" reason I can come up with for not using virtualization. There are just so many advantages and benefits of using virtualization. Some of the benefits of using virtualization; easy to deploy, less downtime (scheduled changes/updates), easier to modify, portable and the use of different OS flavours. These are just some of the benefits, but once you start its hard to go back. My current setup allows me to have 5 linux systems all running within a single core 2 duo all happily chugging away (DNS Servers, Mail Server, Web Server, Radius Server, Build Server). The biggest benefit of virtualization has got to be being able to consolidate space and resources. If you run a data center or lease space in one, virtualization can help dramatically reduce your overall costs by consolidating an entire farm of web servers to a single dual processor system or the such. For those in the development industry being able to test your application in a controlled environment where necessary stressors need to be applied without affecting the rest of the network can all be done from within a virtualized environment. The advantages definitely outweigh the cons I'm afraid. However, making that statement I may be wrong as I haven't tried some of the more CPU intense applications recently so there may be no cons! ... if others would care to comment or correct me please do.
