Computer Networking

RMI stands for Remote Method Invocation. It is a mechansim that allows objects located in different computers in a network to interact. It is usually used in Java. It is quite similar to RPC(Remote Procedural Call).

A. Its double-ring topology.... try using the book now and again :D

And for those of us confused and lost, thank you

Crossbar Switch: A Crossbar Switch connects n inputs to m outputs in a grid, using electronic micro-switches (transistors) at each cross point. The major limitation of this design is the number of crosspoints required. Connecting n inputs to m outputs using a crossbar switch requires n * m crosspoints. For example, to connect 1000 inputs to 1000 outputs requires a crossbar with 1,000,000 crosspoints. A crossbar with this number of crosspoints is impractical. Such a switch is also inefficient because statistics show that, in practice, fewer that 25 percent of the crosspoints are in use at any given time. The rest are idle.

Multistage Switch: The solution to the limitations of the crossbar switch is the Multistage Switch, which combines crossbar switches in several stages. In multistage switching, devices are linked to switches that, in turn are linked top other switches.

The design of a multistage switch depends on the number of stages and the number postages required (or desired) in each stage.

It depends on brand and how much you buy. Usually a box of good cable is approx 25 cents a foot for 1000 feet

There are all different kinds of routers that Belkin makes. Before you buy anything you should make sure to read what it does and what it is used for. If you have any questions or concerns you can ask an electronics clerk or call the manufacturer yourself and ask them any questions you need answered before buying.

The specialized tool for this is usually called a "crimper" or "crimping tool". A knife or cable stripper may also be helpful to remove the outer jacket of the cable; a lot of crimpers have a built-in piece to do this (though the knife or cable stripper generally works better).

One can purchase wireless network adapters from stores that sell computer related products. Examples of such stores would be Best Buy, Walmart, and Future Shop. One can also purchase wireless network adapters online at websites like eBay and Amazon.

A personal computer is usually a stand alone computer in the home and is fully functional by itself. A server computer can do many things, usually used in offices, schools and any other establishment with several machines. A servers main existence is to connect other computers around it and proved services. Such as on a network at one of these establishments let say you click print on a word document, this would then be sent to the server and then sent to the printer nearby. I use to work for a University, they had about 70 servers, quite often a server will have one duty such as a web server which simply sends the websites you want to see to your computer. The Internet is made of servers that share data all day.

Cladding in optical fibre is done for the total internal reflection of the waves propagating inside the fibre. The core of the fibre is made of material with less refractive index value than the material covering the core. When wave falls on the high refractive index material passing through the core it is reflected back.

the control panel applet used to uninstall software is 'add/remove software', click on it then it will have a list of all the software you have downloaded click on the one you want to uninstall and it will expand when you click on it choose a button on it what says 'remove', it might say 'remove/change' but it doesn't matter, anyway click it then it might say somthing like 'do you want uninstall this software' click 'yes' or 'ok' and it will, it doesn't matter if it doesn't say 'do you want to uninstall this software' so don't worry

A network protocol allows two data communication devices to be able to talk to each other. They are necessary because your web browser gets data down to your network card and out onto the network cable

The five components are sender, receiver, protocol, medium and message

"Ping uses the Internet Control Message Protocol (ICMP) Echo function which is detailed in RFC 792"

http://www.activexperts.com/activsocket/tutorials/ping/

So the short answer is that it uses the ICMP protocol.

Fiber optic cables are used to send digital data using pulses of light instead of pulses of electricity. They are made of layers of glass or plastic with an external sheathing and inner core. There are single-mode fibers and multi-mode fibers.

The maximum length of a cat 5 e cable with out a repeater is 100meters

This depends on what "type" of twisted pair. Category 5 ( CAT5 ) cable can transmit up to 100 Mb/s, while Category 6 can transfer up to 1 Gb/s ( 1,024 Mb/s )

The most common twisted pair is CAT5, and CAT5e, used in home networks, business networks, and some multi-line telephone lines.

what type of static route does the administrator configure

ring topology uses token ring i.e one way communication which passes the token with header and Destination address into the network.If one client in the network just disconectd from the network then the the entire network collapse. For this problem FDDI is used for fault tolorence Where as ethernet works much efficiently in packet delivering

As the name says, a back bone network is an interconnection of different networks at the back end.

It is not true. Two computers or devices connectes to each other are in a "network". A basic home network would consist of a bunch of computers and phones connected to a switch via either cable or wirelessly.
