Arrays vs Lists
The key difference between a list and
an array is that an array is fixed size
while a list is dynamic -- you can add
new elements to a list, but to add a
new element to an array you need to
create a new larger array and copy the
old elements.
Arrays are a little leaner and more
efficient if you don't need dynamic
resizing, but lists are usually more
convenient and the performance
difference rarely matters for most
applications.

****Why is the 250GB hard disk
having less than 233 GB?*****
This was a question that one of
my friends asks me after buying a
new 250GB Hard Disk. I really
didn’t ask that question to myself.
So, I couldn’t answer that
instantly. After a few days of
information searching I realize
the truth. So, here I’m going
bringthe facts the way I told my
friend.
All Hard Disk manufacturer way of
counting
space is different from the way a
software count a space. This
means to a Hard Disk
Manufacturer, 1GB is 1000 MB, 1
MB is 1000 KB and so on.
Software or computer language
recognize a space in terms of
power of 2 say 21, 22,23 etc.
hence a KB is 210 Bytes which is
1024 Bytes.
Lets do a little math:
From a Manufacturer a 250 GB
hard disk is
250 x 1000 x 1000 x 1000 =
250000000000 Bytes
From the Computer Language
point of view a 250000000000
Bytes is:
250000000000/
(1024*1024*1024) = 232.83 GB
Now you’ll see why your 250GB
hard disk has only less than
232.83 GB space in total. Well if
you go with higher space like
500GB and so on the space
missing isincreasing.
