What is a smart phone

A smartphone is a handheld personal computer with a mobile operating
system and an integrated mobile broadband cellular
network connection for voice, SMS, and Internet data communication;
most if not all smartphones also support Wi-Fi.
Smartphones are typically pocket-sized, as opposed to tablet computers,
which are much larger. They are able to run a
variety of software components, known as “apps”. Most basic apps
(e.g. event calendar, camera, web browser) come
pre-installed with the system, while others are available for download
from official sources like the Google Play Store
or Apple App Store. Apps can receive bug fixes and gain additional
functionality through software updates; similarly,
operating systems are able to update. Modern smartphones have a
touchscreen color display with a graphical user interface
that covers the front surface and enables the user to use a
virtual keyboard to type and press onscreen icons to activate
“app” features. Mobile payment is now a common theme amongst
most smartphones.

Today, smartphones largely fulfill their users’ needs for a
telephone, digital camera and video camera, GPS navigation,
a media player, clock, news, calculator, web browser, handheld
video game player, flashlight, compass, an address book,
note-taking, digital messaging, an event calendar, etc. Typical
smartphones will include one or more of the following
sensors: magnetometer, proximity sensor, barometer, gyroscope,
or accelerometer. Since 2010, smartphones adopted integrated
virtual assistants, such as Apple Siri, Amazon Alexa, Google Assistant,
Microsoft Cortana, BlackBerry Assistant and Samsung
Bixby. Most smartphones produced from 2012 onward have high-speed mobile
broadband 4G LTE capability and touchscreen starting
to grow in use more.

Semantic Markup

Semantics is the use of HTML to reinforce the semantics, or meaning, of information in web pages
and web applications instead of simply defining its presentation. When processed by traditional
Internet browsers, CSS is used to suggest its presentation to human users. CSS is ideal for designing
documents. You can access any element, or give it a class name and apply a class name. In terms of what
the user sees, a paragraph tag can be made to look similar to a Header tag. If the page has been rendered
in the browser, the user does not care if the text is inside a paragrpah or heads a label as CSS style.

Section 508 Accessibiliy

Section 508, an amendment to the Workforce Rehabilitation Act of the United States of 1973,
is a federal law that requires all electronic and computer technology developed, acquired,
maintained or used by the federal government to be accessible to People with disabilities.

How are they related

The combination of semantaic markup, 508 Acessibility working ogether will provide users a
better experience. Without having semantic markup, it might not be as assessable to those people
with disabilities.
