Internet and Web Architecture Questions and Answers

Answer: B

It is called EDI, Electronic Data Interchange.

EDI is the computer-to-computer exchange of business documents, such as purchase orders, invoices and shipping notices, between trading partners in standard formats like ANSI X12 or UN/EDIFACT, without paper or manual re-entry.

ERP (Enterprise Resource Planning) is integrated software for running a single organisation's internal processes. B2B is the broad category of business-to-business commerce, which may use EDI but is not the name of the standard document exchange itself.

Answer: B

The correct anchor is the one with href="ftp://ftp.google.com", option B.

An HTML link is an a element whose href attribute is given with an equals sign, href="URL", and an anonymous FTP server is addressed with the ftp: URL scheme, as in ftp://ftp.google.com. Option B is the only one with both (the paper prints spaces round the colon and slashes, which are not part of a URL).

Option A uses 'ftpto', which is not a URL scheme. Options C and D write href with a colon instead of an equals sign, which is not valid HTML, and D also uses 'ftp to'.

Answer: A

The statement that is not true is All web browsers support Applets.

Java applets needed the Java plug-in, and modern browsers dropped plug-in support; the applet API was deprecated in Java 9 and removed later. Even in their time, applets ran only where the plug-in was installed.

The other statements are true: applets were a well-known security risk, an applet can open a network connection back to the server it came from, and applets can play audio and display images on the client.

Answer: B

The keyed answer is that an ecosystem is a framework for building an Internet market. In e-commerce the word ecosystem is used for the set of interdependent parties, such as sellers, buyers, payment providers, logistics firms and software platforms, that together make an online market work, so it is a framework for the market and not for a single machine. Building a computer system is a hardware or design task, an offline market is a physical one, and 'building market' is too general and omits the Internet setting that the term belongs to. The keyed answer is Building Internet Market.

Answer: D

Evaluating an employee is not an E-Commerce application.

E-Commerce is the buying and selling of goods and services, and the handling of money, over electronic networks. House banking, buying stocks and conducting an auction are all done online as commercial transactions. Evaluating an employee is an internal personnel matter and does not involve a commercial exchange.

Answer: D

ActiveX controls are Pentium binary programs that can be embedded in Web pages. A browser such as Internet Explorer downloads the control and runs the compiled code on the user's machine, which gives it speed but raises security concerns.

'Word pages' and 'URL pages' are not categories of embedding targets, and script pages hold interpreted code such as JavaScript, not compiled binary controls.

Answer: B

The EDI document standards were first developed by large businesses in the 1970s and are now controlled by ANSI, through the ANSI X12 standard. The accredited standards committee defines the formats of the business documents.

ISO is an international standards body, but the question names the US body. ITU-T deals with telecommunications standards and IEEE with electrical and computing standards, neither of which owns the EDI document standard.

Answer: B

EDI software consists of four layers: the business application, the internal format conversion, the EDI translator and the EDI envelope. The application produces the data, the conversion layer turns it into an intermediate form, the translator converts it to the EDI standard format and the envelope wraps it for transmission.

The option with a 'network translator' is not an EDI term. The remaining two options mix in transport and IP layers, which belong to the network protocol stack and not to EDI software.
