Computers are not god gifted these are human
creations..humans just like u and I..
Those legends make their imaginations true
with computer science.
ohky I suppose u know the individual meaning
of computer and science..but what is computer
science or CS..
In simple words
it just a process of solving problems..solving
problem means to give some input and get some
output or solution to a particular problem..but
the question come how we get output from this
blank box..
 .: It's something which
we call algorithms..
Means Certain steps to get the output...just
like solving a math problem we go step by
step and sometimes different steps followed
by various ppl but they got the result correct..
It differs bcz of computational thinking of
person to person..about how they get a particular
problem and what certain steps they gonna
follow for better result..
this step by step procedure is called algorithm..
For instance ...when we prepare instant noodles
there is process to make it..
After performing some steps we our desired
food..
This is also an algorithm..
It's just a computer term but its boundaries
are spread all over..
Not only computers but humans also perform
algorithms..
Some set of instructions..
Let just know how these instructions are given
to the system..
when we consider a problem to be solved, how
we represent the input, I mean there is a
requirement of some sort of language or something
to communicate , especially when we are talking
with machines..
as most of us know that the brain of computer
can only understand binary, zeros and ones,
binary is nothing but a system of counting..like
tally marks and ten positional system or decimal..
we all familiar with it from the beginning
with 10 digits..0,1,2,....9..
We add a new digit after every ten things..
In decimal this is four hundred twenty seven..and
we all know how...because the power of 10
keep on increasing..and after multiplying
the digits with increasing power of 10 gives
us addition value...four hundred and twenty
seven..
And in binary bi means two..
Which means
Increasing power of base 2 on addition of
more bit ...
.: Each bit is generally a single number either
one or zero
Addition of more bits or digits technically
means need more hardware to store larger numbers
with the help of these two numbers, computer
can store numbers, letters, images , videos
and many more.
More and more bits are required for files
with larger size..
Here must be a question going through head
that why we are not using decimal system in
computer..
Instead of binary ,having only 2 digits..
The only answer is bcz computer works with
electricity and it may be on or off..zero
for off and one for on...
Just think of switch which could only be on
or off...in a system there are millions or
trillions of these kind of switches inside
it called transistors.
