Computer Internet Questions and Answers

Answer: A

Correct answer: E-business

E-business is the broadest of the four: it covers every use of electronic platforms in running a business, internal as well as external. E-commerce is the narrower activity of buying and selling, and e-marketing and e-procurement are narrower still.

Answer: A

Correct answer: Digital subscriber line (DSL)

DSL uses the same copper pair as the telephone but transmits at frequencies above the voice band, so it is far faster than a dial-up modem and the line remains usable for calls. Cable and fibre are faster still but do not use the phone line.

Answer: C

Correct answer: Protocol

A protocol is the set of rules governing how data is exchanged. The internet and the web are what those rules are used to build.

Answer: D

Correct answer: All of the above

All three are true of a firewall: it may be implemented in hardware or in software, it examines the traffic crossing a boundary, and what it does with each packet is decided by a configured set of rules.
