Which protocol is used to access the Internet by mobile devices?

• A. Wireless Application Protocol (WAP)
• B. Web Access Protocol (WAP)
• C. Wireless Access Point (WAP)
• D. Web API Protocol

Answer: (A)

Wireless Application Protocol is the protocol designed to let mobile devices access the Internet, especially those with small screens and limited bandwidth. It was created to optimize content for mobile use, using a compact markup and a tiered protocol stack (including WSP, WTP, WTLS) and often a WAP gateway to bridge to the broader Web. This makes it the best fit for the idea of mobile Internet access, as it specifically targeted how phones and similar devices would retrieve and render information over wireless networks. The other options don’t describe a protocol for mobile Internet access: a wireless access point is hardware, not a protocol; a Web API Protocol isn’t a standard term; and a so-called Web Access Protocol isn’t a recognized protocol name.
