terminology - Simulator or Emulator? What is the difference? -

-

However, I understand that I'm almost always confused about the meaning of simulation and emulation. Suppose I will make a piece of software that mimics the existing hardware / software, what should I say? A simulator or an emulator?

What can explain the difference in programming?
Bonus: What is the difference between English between these two words? (Sorry, I'm not a native speaker):

emulation, externally imitating observational behavior The process of doing is to match the existing goal, the internal state of the emulation system does not accurately reflect the internal state of the target, which is simulating it.

Simulation, on the other hand, involves modeling the underlying position of the goal. The end result of a good simulation is that the simulation model will emulate the target that it is simulating.

Ideally, you can check the simulation and inspect the properties, which you see in the original goal, you will also see this. In practice, there are some shortcuts to simulate performance reasons - that is, some internal aspects of simulation can actually be a simulation.

MAME is an arcade game emulator; HyperTermum is a (not very good) terminal emulator. There is no need to prepare the arcade machine or terminal to achieve the desired simulation behavior.

Flight Simulator is a simulator; Spice is an electronics simulator, they make every detail as much as possible of the goal of representing the goal as possible, as much as possible.

EDIT: Other responses have indicated that the simulation target is based on the location of the object. This is an important point, the goal of a simulation is more on the modeling of the target's internal state - and the simulation does not lead to essentially emulation. In particular, a simulation can run slower than the real-time. Spice, for example, can not substitute for an actual electronics circuit (even if there was such a magical device which interfaces electrical circuits completely for spice simulation.) A simulation simulation is not always for simulation -

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

-
I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
