PPT On Wireless and Satellite Communication
Why Terrestrial Wireless :
1. Alternative to fibre and copper wire
2. New technology: deliver today´s services and meet tomorrow´s demands
3. Low start-up costs: need to install base stations only,"pay as you go", viable for low penetration rates
Near Future:
1. Terrestrial broadband systems licensed and starting to roll out around the world.
2. Broadband Multimedia Satellite systems beginning services this year with many more to be launched the next 5 years, providing global broadband access.

PPT on File Handling in C
Files are places where data can be stored permanently.
Some programs expect the same set of data to be fed as input every time it is run.
Cumbersome.
Better if the data are kept in a file, and the program reads from the file.
Programs generating large volumes of output.
Difficult to view on the screen.
Better to store them in a file for later viewing/ processing

Distributed System Practicals
1. Write a Program in RMI by which Client send
hello message to Server.
2. Write a Program in RMI by which you can add
two numbers.
3. Implementation of a Gross server in RMI. Gross
server calculates the basic salary, HRA, DA
passed by the client & returns it to client.
4. Implementation of a File access server in RMI. File
server returns the content of a file that is stored
on that server to client when requested by the client.
5. Implementation of a DNS server in RMI. DNS server
returns the IP address of a text URL to client, passed
by the client to server in request.
6. Write a Program in RMI in which client send a message
to a sever and server stores it in the file at server machine.
7. Implementation of a Authentication server in RMI.

public static void main(String[] args)
{
try
{
return;
}
finally
{
System.out.println( "Finally" );
}
}
}
A.Finally
B.Compilation fails.
C.The code runs with no output.
D.An exception is thrown at runtime.
Answer: Option A
Explanation:
If you put a finally block after a try and its associated catch blocks, then once execution enters the try block, the code in that finally block will definitely be executed except in the following circumstances:
1. An exception arising in the finally block itself.
2. The death of the thread.
3. The use of System.exit()
4. Turning off the power to the CPU.
