CAPTCHA….

                                                                                                                           Y6FPRSB4CZPE

                    

          A CAPTCHA is a type of Challenge response test used in Computing as an attempt to ensure that the response is generated by a person. The process usually involves one computer ( a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are assumed to be unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. Thus, it is sometimes described as a reverse turing test, because it is administered by a machine and targeted at a human, in contrast to the standard Turing test that is typically administered by a human and targeted at a machine. A common type of CAPTCHA requires the user to type letters or digits from a distorted image that appears on the screen. It is an acronym based on the word "capture" and standing for "Completely Automated Public Turing test to tell Computers and Humans Apart".

A modern CAPTCHA, rather than attempting to create a distorted background and high levels of warping on the text, might focus on making segmentation difficult by adding an angled line.

           CAPTCHAs are used in attempts to prevent automated software from performing actions which degrade the quality of service of a given system, whether due to abuse or resource expenditure. CAPTCHAs can be deployed to protect systems vulnerable to e-mail spam, such as the webmail services of Gmail, Hotmail and Yahoo-mail.

404 error....

   

       A 404 error is a common website error message that indicates a webpage cannot be found. It may be produced when a user clicks an outdated (or "broken") link or when a URL  is typed incorrectly in a Web browser's address field. Other websites simply display the Web server's default error message text, which typically begins with "Not Found." Regardless of the appearance, a 404 error means the server is up and running, but the webpage or path to the webpage is not valid.

       So why call it a "404 error" instead of simply a "Missing Webpage Error?" The reason is that 404 is an error code produced by the Web server when it cannot find a webpage. This error code is recognized by search engines , which helps prevent search engine crawlers from indexing bad URLs. 404 errors can also be read by Web scripts and website  monitoring tools, which can help webmasters  locate and fix broken links.

Emulation...

The term "emulation" comes from the verb "emulate," which means to imitate or reproduce. Therefore, computer emulation is when one system imitates or reproduces another system. This can be done using hardware, software, or a combination of the two. However, since hardware is expensive to reproduce, most emulation is done via software.

One of the most common types of software emulation involves running different operating systems in a virtual environment. For example, programs like Parallels Desktop, VMware, and Apple's Boot Camp allow Windows and other operating systems to run on an Intel-based Macintosh computer. Sun Microsystems' xVM VirtualBox allows multiple operating systems to be run on Windows, Mac, and Unix platforms. These applications are collectively referred to as software emulators, since they emulate different computer systems.

Another popular type of software emulation allows console video games, such as Nintendo, Sega, and PlayStation games, to be run on a PC. The program ZSNES, for example, allows Super Nintendo (SNES) games to be played on a Windows or Unix machine. The Virtual Boy Advance emulator allows users to play Game Boy Advance games on Windows or Macintosh computers. Games for these emulators are saved as ROM files, which are exact copies of a game cartridge or disk. Therefore, instead loading a physical cartridge, video game emulators simply load ROM files from the computer's hard drive.

A third type of emulation uses a type of file called a disk image. While ROM files are used to emulate game cartridges, disk images can be used to emulate optical media and physical hard disk. For example, an .ISO file (Windows) or .DMG file (Mac) can be mounted on the desktop, which makes the operating system view the file as a physical disk. This provides an easy way to make exact copies of CDs, DVDs, and hard disks. Disk images are also commonly used to create virtual installer disks that can't be modified by the user.
