the server will be set up with IIS - Internet Information Service which allows website to be hosted or Apache if using Linux or other Web service software
generally a web server hosting loads of site will have lots of hard drive space and RAM and powerful processors for running a couple site done need anything really fancy
How does a virtual lAN allow devices to be grouped?
Devices in the same VLAN are part of the same subnet, or "group". (The fact of belonging to one VLAN or another is, to a certain degree, independent of the physical location, thus the name "virtual".)

Difference between Campus area network and MAN?
That is used just on campus like a university. It is used as a large LAN type environment owned by one person or company. MAN is metropolitian and it would be more like a satellite connection for a whole city, and own by gov or state officials, and not one person or company.
How will you protect or prohibit unauthorized users from accessing the company LAN?

First step for cyber security is a good firewall. For physical security you need access control (locked doors and card entry, ect).

What is the difference between context switching and mode switching?
Context means ,in terms of computers, the status of various general purpose registers having some process specific data values and even some other structures dependent on computer hardware,i.e. PCB etc.
Now what context switch means ,""switching from one status of registers set to another status of registers set.""
This context may be of a process or thread etc.
Now when we are talking about any type of context switching,,it means we are requesting the KERNEL to save the current context anywhere,and fetch the next context for us..
It requires a mode switch between user mode to kernel mode, so that required switching may be performed in right order....
Isn't it simple ,,or what.
