4. Today’s Topic
• Using electronics today is so much a part of our daily lives we hardly think of the way the world would be without electronics. Everything from cooking
to music uses electronics or electronic components in some way. Our family car has many electronic components, as does our cooking stove, laptop
and cell phone. Children and teenagers carry mobile phones with them everywhere and use them to take and send pictures, videos, and to play music.
They send text messages on the cell phone to other phones and to their home computers.

• Higher Accuracy
• Not Everyone Can Read Analog
Clocks
• Readable In the Dark
• This is important since 25 percent of Americans are late
for work once a month or more. You need a clock that
shows you the exact hours and minutes so that you can
plan your time more effectively. Accuracy also helps at
home when cooking or doing other projects.
• Manufacturers can incorporate a number of features into
any digital clock. This allows you to have a clock that can
also function as an alarm, a radio or even a stopwatch. It
can often be more helpful to have a compact digital clock
in the home with extra features to make things easier.
• This can be a real problem in your household if your
guests, children or younger family members come over
and need to know the time. Digital clocks are very clear
and just show numbers. They are instantly readable
without having to possess special knowledge.
• One possible cause is that analog clocks are not visible at
night in the dark. This leaves you wondering what time it
is or attempting to judge the time by the dim light
outside. Digital clocks use a liquid crystal display, or LCD,
face that will glow brightly in the dark. This lets you
always see the time even in total darkness.
