please koi to post karo solution..

 

In the modern age a vast range of communicating devices are operated and used in wireless environment, i.e Bluetooth, Infrared, GPRS and Wi-Fi. These are good sources of unguided media in the modern age. The wireless network will cover a vast range of communication in near future. It has main advantage of cable less communication which saves additional cost for cabling. Now a day a lot of remote controlled toys are using radio way technology which is a wireless communication and covers communication or signaling distances up to some extent. Any how warless communication is limited to some specific working range or distance. Wireless communication usually has less data transfer rate as compared to cabled/wired network. Therefore we will still have to continue using wired communication because it covers more communication distance and more data transfer rate. 

Please do not make exact copy. make changes before uploading otherwise u will get zeor marks

i don't think so that it has less data transfer rate and its range is limited because we control all Satellite from earth through signals not with wires...

CS601-Data Communication
Dear Students!

Graded Discussion Board will be launched on Wednesday February 06, 2013 and it will be remained open for two days (February 06 to February 07, 2013).


The topic of Graded Discussion Board:




Day by day, our communication is being furnished with new and more sophisticated wireless devices and the trend in the use of wireless equipment is increasing extensively. Do you see that in future, all networks based on physical communication media will completely be replaced by the wireless media where every device in the network will be without wire? In your opinion, will it be possible to have every network without physical communication media or there will always be the need of physical communication media for networks? Give solid reason supporting your opinion.

Idea Solution


Physical media


With physical media we mean channels where the person who is talking can be seen and heard by the audience. 
The whole point here is to be able to not only hear the messages but also to see the body language and feel the climate in the room. 
This does not need to be two-way channels. In certain situations the receiver expect physical communication. This is the case especially when dealing with high concern messages, e.g. organizational change or down sizing. If a message is perceived as important to the receiver they expect to hear it live from their manager

Wireless network 


Wireless network a magic word which can change your status very promptly that can get access to internet very speedily, and make possible conversation more and more than two users such as text messages, downloading and uploading of pictures, hear online radio, music and video downloading with a very high speed. Wireless network offering hotspot therefore now the usage of internet at airport, business companies is not an issue now.

Nice keep it up

well physical media doesnt mean the place where we cah see or touch people....  physical media means the channals which help in connection to internet  as cables.... and in this GDB they asked us to tell that will there always a need of such channels in future or not!! 

@cute girl wah cute girl ap ka answer is exemplary 

As we all know wireless network is the most important part of any business ,industry or project now- a-days .This technology makes our lives more comfortable and effective in the form of mobiles,laptops and radio.Now wireless network also offering hotspot therefore the usage of internet at airports and business companies is not an issue,But besides all this , its not possible to use this facility without physical communication media in my opinion Submarine internet cable is the example of this issue which is the basic and most fundamental part of internet in the form of physical communication media.
