3. DISCREATE MATH IN COMPUTERS
Computers run software and store files. The software and
files are both stored as huge string of 1s and 0s Binary
math is discrete mathematics. All computer data is
represented using binary. Binary digits can be grouped
together into bytes.

4. Discreate math in Railway planning
Railway planning uses discrete math deciding how to
expand train rail lines, train timetable scheduling, and
scheduling crews and equipment for train trips use both
graph theory and linear algebra.

5. Discreate math in Computer graphics
Computer graphics (such as in video games) use linear
algebra in order to transform (move, scale, change
perspective) objects. That's true for both applications like
game development, and for operating system
XY rotation matrix:

6. Discreate math in cryptography
Cryptography is a method of storing and transmitting data in a particular form so that only
those for whom it is intended can read and process it. Cryptography provide secure any
data or passwords in encryption methods.

7. Discreate math in Google Maps
Google Maps uses discrete
mathematics to determine fastest
driving routes and times. There is a
simpler version that works with small
maps and technicalities involved in
adapting to large maps.

8. Image processing
Image processing is a method to
convert an image into digital form and
perform some operations on it, in
order to get an enhanced image or to
extract some useful information from
it. It convert image as two
dimensional signals.

10. Automatic Doors
Infrared sensors
These specialized sensors use infrared technology to
trigger the opening/closing of doors. These sensors detect
changes in temperature in the area surrounding the doors,
so when an individual approaches the doors, their heat
signature is detected by the sensors, which cause the
doors to fly open!

11. Microprocessors
A microprocessor, sometimes called a logic chip, is a
computer processor on a microchip. The
microprocessor contains all, or most of, the central
processing unit (CPU) functions and is the "engine"
that goes into motion when you turn your computer on.

12. fitness tracker
An activity tracker, also known as a fitness tracker, is a
device or application for monitoring and tracking fitness
related metrics such as distance walked or
run, calorie consumption, and in some cases heartbeat
and quality of sleep.

13. Digital electronic safe box
Electronic digital safe is perfect for securely storing your
jewelry, valuables and confidential paper work. It features
an easy to set electronic code with floor or wall mounting.
There is also a digital lock, incorrect password alarm and
two back up keys. There is a cash box with tray to keep
your valuables and coins in and a carrying handle for your
convenience.

14. Fingerprint Optical Scanner
Fingerprint Optical Scanner measures your finger electrically.
Only specific characteristics, which are unique to every
fingerprint, are filtered and saved as an encrypted
biometric key or mathematical representation. No image
of a fingerprint is ever saved, only a series of numbers (a
binary code), which is used for verification. The algorithm
cannot be reconverted to an image, so no one can
duplicate your fingerprints.
