Presentation on various applications of encoders and decoders with examples.

1. APPLICATIONS OF
ENCODER’S,DECODER’S

2. 1.DATA PRIVACY & SECURITY
 Secure layer of communication over the web such
as SSL which is used in secure websites (HTTPS)
you daily browse, VPN services to access office
network securely etc.
 Encrypting files, hard drive and PDF password
encryption are few examples of it.

3. 2. DATA COMMUNICATION
 Converting data into digital bits so that our electrical
and wireless media could represent it via high and
low signals, example : modems used to connect
internet.
 Modulating data with a high carrier frequency to avoid
long distance signal degradation, examples : all
forms of wireless communication like Wi-fi , FM
radio, cellular phone services etc.

4. 3. DATA COMPRESSION
 Music, Video/Photos capturing/recording, playing or
even streaming over the internet would not have
been possible without compressing it into
manageable size. Here we use compression
techniques like mpeg4, mp3, jpeg etc.
 We daily save our hard disk memory space
by RARING and ZIPING our large chunks of data.

6. 4.DATA SCAN
 In some cases we may need to quickly grab the data
from something instead of reading and manually
inserting into the computer, such as in a retails store
at the checkout to generate bill. For obvious reasons
we would want to utilize the computing power of our
smart phones and computers to store and manage
the data. To name a few, we use barcode and QR
codes very frequently nowadays.

7. 5.MAKE DATA HUMAN READABLE
** Humans use different languages to read and write
which requires a lot of character types hence the
need to character encoding standards
like ASCII and UTF, we also see a lot of emojis
nowadays, which are extensions of these encodings.
