What is maximum forward current in case of diodes?
the maximum amount of current that a forward-biased diode can withstand before burning out or being seriously degraded.
What is priority queue?
A priority queue is a collection of elements that each element has been assigned a priority and such that order in which elements are deleted and processed comes from the following riles: 1) An element of higher priority is processed before any element of lower priority. 2) Two element with the same priority are processed according to the order in which they were added to the queue.
What is difference between HttpModule and HttpHandler?
HTTP handlers are the end point objects in ASP.NET pipeline and an HTTP Handler essentially processes the request and produces the response. For example an ASP.NET Page is an HTTP Handler. HTTP Modules are objects which also participate the pipeline but they work before and after the HTTP Handler does its job, and produce additional services within the pipeline (for example associating session within a request before HTTP handler executes, and saving the session state after HTTP handler has done its job, is basically done by an HTTP module, SessionStateModule) HTTP handlers HTTP handlers are the .NET components that implement the System.Web.IHttpHandler interface. Any class that implements the IHttpHandler interface can act as a target for the incoming HTTP requests. HTTP handlers are somewhat similar to ISAPI extensions. One difference between HTTP handlers and ISAPI extensions is that HTTP handlers can be called directly by using their file name in the URL, similar to ISAPI extensions. HTTP Modules http://blbirajdar.blog.co.in HTTP modules are .NET components that implement the System.Web.IHttpModule interface. These components plug themselves into the ASP.NET request processing pipeline by registering themselves for certain events. Whenever those events occur, ASP.NET invokes the interested HTTP modules so that the modules can play with the request.
Write a program to demonstrate the catching of all exceptions what happens when a raised exception is not caught by catch block in the absence of a catch all exception block?
If an exception is not caught then your program has undefined behaviour. Ultimately the program crashes, but since you haven't handled the exception you've no way of knowing what damage has been done. Files could be wiped or currupted, planes could fall from the sky... anything is possible with undefined behavour. The best way to deal with unknown exceptions is to first catch them with a catch-all. However, you cannot actually handle the exception unless you know what type of exception you are actually dealing with. Thus the normal course of action is to assume the worst, perform any and all necessary cleanup, log the exception as an unknown exception and rethrow. As the exception percolates back down the call stack, all other exception handlers should do the same: cleanup, log and rethrow. If you're lucky, another handler might recognise the exception and be able to provide more detailed information on the type of exception. Ultimately you must never allow a program to continue executing if you cannot handle an exception. C++11 offers a more elegant solution using a nested try catch within a catch-all. However, it makes more sense to place the nested try catch in a global function (e.g., handle_eptr()) which can specifically deal with all catch-all exceptions. Like so... #include <iostream> #include <string> #include <exception> #include <stdexcept> void handle_eptr(std::exception_ptr eptr) { try { if (eptr) std::rethrow_exception (eptr); } catch (const std::exception& e) { std::cerr << "Exception: "" << e.what() << ""\n"; } } int main() { try { std::string().at(1); // throws "invalid string position" } catch(...) // catch-all { // perform any necessary cleanup here before calling the global handler handle_eptr (std::current_exception()); } } Output: Exception: "invalid string position" Note that handle_eptr() receives a std::exception_ptr. By itself this is useless, but std::rethrow_exception() converts the eptr to a standard exception which can then be thrown, caught and logged. You must still perform any necessary cleanup and allow the program to terminate gracefully, but at least you now know what type of exception you are dealing with and can provide a specific handler to handle it. Note that handle_eptr() should be fleshed out to accept all necessary debug information such as the filename and the line number from the catch_all that called it. The example merely demonstrates how to pass the eptr and convert it into an actual exception.
What is ceiling voltage in exciter?

Does silicon need to be processed before it is used?
yes it needs to be processed before it is used
Which molds the fastest bread processed cheese or processed ham?
Typically when mold is present on food, you want to throw it away. As a result of the process the food goes through before it is packaged for shipping, processed cheese will grow mold before a processed ham product.

Well, you have to get them from someplace. They have to be extracted from the ground before they can be processed.
What army regulation covers commanders exception reports?
SAMS-1E End User manual & DA Pam 738-750 Para 12-16 bb. Commander's Exception Report. This report provides a listing of all requests having a high priority or extended value of $500 or more that have been processed since the last time the Commander's Exception Report was printed. The Commander's Financial Transaction Listing (fig. 12-18) must be reviewed and initialed before the daily transactions are sent to the DSU. Any request not approved can be canceled before transactions are sent to the DSU.
