Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

How will you break a subnet into two smaller subnets?
To break a subnet into two smaller subnets, you need to extend the subnet mask to create additional bits for subnetting. For example, if you start with a /24 subnet (e.g., 192.168.1.0/24), you can change the mask to /25, which divides the original subnet into two subnets: 192.168.1.0/25 (with addresses from 192.168.1.0 to 192.168.1.127) and 192.168.1.128/25 (with addresses from 192.168.1.128 to 192.168.1.255). This effectively doubles the number of subnets while halving the number of usable IP addresses in each new subnet.
Difference Between RPC and RMI?
The only real difference between RPC and RMI is that there is objects involved in RMI: instead of invoking functions through a proxy function, we invoke methods through a proxy.
What this means in practice is that we now want the client to hold references to remote objects that it can invoke methods on. These references should behave just like local objects, but when invoked dispatch the method invocation to the remote object.
Because we need to refer to both an object and a method now - not just a function - we extend the protocol so it first sends an object id across the socket, then the method and then the arguments. The server then dispatches the method to the remote object based on id and method name.-Rituparno Ganguly
10BaseT has transmission rate about 10 Mbps and 802.11b is about 11 Mbps. Usually wire connections are closer to their theoretical limits than their wireless counterparts.
Why can you only populate 3 segments of a 5 4 3 network?
The other two segments must be link segments - connecting through network connectivity devices. Adding any clients on those two links would cause additional attenuation, which is not good for the network.

What is the benefits of using layered network model?
The idea of layered software is to encapsulate or limit what an area of software might do. The various layers give you the multiple protocols that networks will utilize.
If a layer specializes in just one thing, adding more layers allows one to add more functionality to the overall scheme of things. It is generally considered a bad idea in software engineering to put too much in a single layer; it is better to spread out the responsibilities of things in several layers.
How to maintain and verify routing information?
To maintain and verify routing information use the show version command.
What does IP mean in security cameras?
IP stands for Internet Protocol (just like IP Address, etc). In other words - if you see a security camera that is marked as an IP Camera, it means that that camera can be hooked up to and viewed on a network.
Most IP security cameras have their own web server, which means that you can plug it into a standard router or switch, assign it an IP Address on that network, and view it from Internet Explorer or other specific software meant to view and record IP cameras.

What is a Hostname or IP address?
The hostname of my main computer running Ubuntu 13.04 is rodney@downstairs. rodney is my user name, and downstairs is the host name of my computer. To find your IP address, open a terminal (Ctrl + Alt + Tare the shortcut keys I like using) and type: ifconfig and press Enter. Your IP address may look something like: 192.168.1.x (x being a unique number to identify each computer or device on a network).
Types of computer servers include web servers and storage servers. A web server services client requests made by the visitors of the website it hosts while a storage server provides data storage facilities.
What is the difference between the pyramiding and networking?
Pyramiding is the schematic diagram of attaining such goal and networking is one method or tool in attaining that goal you wanted to reach or attain.
What is the importance of classifying the networks?
Not very much if its home it'll automatically link you to it if work same but public u have to select.
It will broadcast to every port in the vlan.
Among TDM and FDM which one is noisy?
tdm: total available time is divided into several user
eg: telephone system
fdm: total frequency bands are divided into several users
eg : television broad casting
wdm: total wave lengnth is divided in to number of users
eg: optical networking
These are particular one line definitions of tdm, fdm and wdm but you should realize that there is no difference in fdm and wdm, they are different terms talked in context of radio waves and optical fiber accordingly. As both light waves and radio waves are electro magnetic waves there speed is same so if you are dividing frequency or wave length both are leading to same.
