Now let's talk about one coding scheme which is called BCD
Before this I have read this coding scheme that was sky vote
Here one thing comes EBCDIC
Now what is this EBCDIC
I will tell him that this is also your coding scheme
Now tell me about this coding scheme
What things are written in it
EBCDIC stands for Extended Binary Coded Decimal Interchange
Code
Which was BCD
It has been improved a little
And what it has brought? EBCDIC
It uses 8 bits to represent a symbol
If I talk about BCD
What BCD used to do?
BCD used to represent data in 6 bits 1,2,3,4,5 If I talk
about BCD vs EBCDIC
Here I will get to know that 1,2,3,4,5,6,7 Means 8 bit
representation
What was in BCD?
In BCD I had 6 bit representation
So I understood both of these things
Now here it can represent 256 different characters
What it could do?
It could show 64 different characters
But what it can do?
This is your coding scheme
It can represent 256 different characters
So this is the benefit
The more you can represent the character
The better it is for you
Now let's see the coding of alphabetic and numeric
characters
How it is given in alphabetic and numeric characters
If I talk about alphabets
My character is given
And in hexadecimal
This is my C1
What is given here?
It is given a zone
You belong to 001
Its digit is 1100
Similarly, my others are given
Like I took I
What is in I?
Same thing
What is the digit given to me?
It is given 1100
And what is the zone here?
It is my 1,001
And in hexadecimal it is C9
So in this way, my whole table is given
You can see this table
What is here?
All these things have become alphabets
And what is here?
It is characters
So characters and alphabets were also in our BCD
You can see characters and alphabets in our coding scheme
Which is your EBCDIC
Very good
So let's move forward
Zoned decimal numbers
Now this thing was going on
What are zoned decimal numbers?
See here
Let's read a little text
What is written here?
Zoned decimal numbers are used to represent numeric values
If you want to represent numeric values
Then zoned decimal numbers are given
For positive, negative, unsigned
In EBCDIC
It is given in EBCDIC
Sign indicator C
If C is written then what is it for?
It is for plus
D for minus
F for unsigned
It is used in the zoned position of the rightmost digit
Let's see examples
Zones for all other digits remain as F
The zoned value for numeric character in EBCDIC in zoned
format
There is only one digit per byte
It means one digit per byte
Zones for all other digits remain as F
It means whatever digits are left
For that, you will write F
Like the example given here
Let's see an example
Here is your numeric value 345
The same numeric value is given in plus and minus
If you want to show it here
Then see
What is F3, F4, F5?
This is for F4 unsigned
There is no sign D
Can you see anything here?
Tell me
Here you can't see plus
Neither can you see minus
Nothing is visible here
Now let's talk about C4 positive
Here your C is positive for what?
You can also see the sign of positive
If I talk about D, then what is D for you?
Here is negative
What is D for you?
It represents negative
So what happened here?
I got this minus
Here is the sign of D
Now let's talk about packed decimal numbers
What is this?
Packed decimal numbers are formed from zoned decimal numbers
What can we make from the zoned decimal numbers?
We can make packed decimal numbers from them
How to make them?
Follow the steps
Tell me what are the steps?
Step 1
The zoned half and the digit half of the rightmost byte are
reversed
What you have to do is
You have to reverse the zoned half and the digit half
All remaining zones are dropped out
And drop out the remaining
Packed Although it is not much
Packed decimal format requires fewer numbers of bytes than
zoned decimal format for
Leave it
Numbers represented in packed decimal format can be used
for arithmetic operations
What are the examples?
Conversion of zoned decimal numbers to packed decimal
numbers
See the numerical value is given
The numerical value was also given there 345 plus 345 minus
345
And what is written here? 3456 Now if you look here
Sign indicator
F, C, D, F
It does not matter much
We did not have this kind of value before
Sign indicator
We used to have this
F, C, D
Now we have done
Sign indicator
Do not go into so much depth
Now let's see the example of this coding scheme
Using binary notation write EBCDIC coding for the word bit
What do you have?
You have a word
Bit How many bytes are required for this representation?
How many bytes do you need?
Sorry, how many bytes do you need?
I will give B
Now see here
One thing will be your zone
And one thing will be your digit
This is your
I I In this case, you have been given the same
Let's check the cross
Let's check the B
Let's see what is given in B
My digit is 1100 and my code is 0010
So my code is 0010
So let's go here and see
My code is 0010
And what I have is
This is 0010
Which is my digit
Hence I am coding for the byte bit in binary notation
You will write the zone and the code
This is your zone and this is your digit
You have written it like this 3 bytes will be required for
this representation
Because each letter requires 1 byte
You can count it as 1,2,3,4,5,6,7,8
This means how your B is being represented
Your 8 bits are being represented
And your T is also being represented
In the same way
So we saw that I had a BCD coding scheme
After that I had an EBCD coding scheme
In which I got to see
How can I store my numbers and alphabets
It was in 6 bits and then it became 8 bits
Now let's talk about ASCII which is very important
We also looked at the table above
ASCII stands for American Standard Code for Information
Interchange
If you want to exchange information
What can you do more
You can do this
You have to follow the American Standard Code
ASCII is of two types
ASCII is also like this
ASCII 7 was not there before
So we got to see the upgraded version
ASCII 7 uses 7 bits 7 bits to represent a symbol
And can represent 128 different characters
What can ASCII 7 do
It can represent 128 different characters
If I talk about BCD
It can represent 64 characters
ASCII 8 takes 8 bits to represent a symbol
And can represent 256 different characters
First 128 characters
ASCII 7 and ASCII 8 are same
Means the previous 128 characters are same
But when it comes to 129 and 130
Then what is the use of ASCII 8
Let's see the coding of numeric and alphabetic characters
What is given in it
This is numeric
And here are the alphabetic characters 0,1,2,3,4,5,6,7,8,9
These are the characters
Here is the ASCII 7 0011 Here are the digits
1,2,3,4,5,6,7,8,9 0011 Now you will understand how to get
this
It is very simple 0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8
0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8
0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8 0011
0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8
0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8
0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8
0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8 0011 0011 0011 0011
0011 0011 0011 0011 0011 0011 0011
0011 0011 0011 0011 0011 0011 0011 0011 0011
0,1,2,3,4,5,6,7,8 1,2,3,4,5,6,7,8 1,2,3,4,5,6,7,8
1,2,3,4,5,6,7,8 1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8
0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8 0,1,2,3,4,5,6,7,8
0,1,2,3,4,5,6,7,8 for its representation and there are
3 characters in the word sky 3 bytes will be required for
the representation.
I understood this very well, that's all in it, so what did
I understand in it, let's see this thing quickly, we saw in
it that your sky code is used, means you have a lot of
coding schemes, generally you have coding schemes, what
coding schemes are there?
you have a lot of coding schemes, you have a lot of coding

Remember to spread the word to all my classmate.
