Sending a message to a group is called multicasting, and its routing algorithm is called multicast routing

IEEE 1394 (Firewire) supports the maximum of 63 connected devices with speeds upto 400 Mbps.

main()

{

   char *str[] = { "Frogs", "Do", "Not", "Die." , "They", "Croak!" };

   int i;

         for ( i = 0;i<=5;i++)

         printf ("\n%s%d", str[i], strlen( str[i]));

}

The order may vary from compiler to compiler.

Here the multiplication will happen before the addition , but in which order the functions would be called is undefined. In an arithmetic expression the parentheses tell the compiler which operands go with which operators but do not force the compiler to evaluate everything within the parentheses first.

1.The hardware

2.The operating system

3.The application programs

4.The users.

Integration testing is done at module level when various modules are integrated with each other to form a system or sub-system. Its main purpose is to ensure that interfaces between various modules are working properly; i.e. modules which are working individually are also working correctly together.

System testing is done on a complete, integrated system to evaluate the system’s compliance with its specified requirements. It validates that the system meets its functional and non-functional requirements.

From these definitions, it is clear that the purpose of Integration and purpose of System Testing are different. Therefore, Integration test cases focus more on the interfaces between modules (interface integrity) - the data transfer and their interaction with each other. System test cases focus on testing the product as a whole; i.e. whether the functional, non-functional requirements of the System are met or not. Since System Testing is the final phase before delivery of the product, System test cases should pinpoint configuration related errors along with testing for performance, security, reliability etc.

To clear the CMOS password you just remove the CMOS Battery or else you can also use a jumper settings.

In batched operating system the users gives their jobs to the operator who sorts the programs according to their requirements and executes them. This is time consuming but makes the CPU busy all the time.
