Here in,
recordSetVar="accounts"
we are assigning a variable to standard controller Account so that we can use it easily instead of writing Account everywhere, generally we use any small length variable but it does the same function.
For,
<apex:pageBlockTable value="{!accounts}" var="a">
we are iterating over all accounts i.e. as in Loops, we need a temperory variable to iterate.
Similarly, we are using "a" over here.
Please mark it as best if you find it helpful.
Thanks

In the above code, you are iterating over all the accounts using standard controller.
So, while iterating over those accounts you will require a variable i.e "a" here.
But
e.g. if you go for creating accounts from the page by taking name as input then you would not require another variable "a". you can use recordsetvar.

recordSetVar="accounts" Here what is accounts having?
and what about this <apex:pageBlockTable value="{!accounts}" var="a"> ??
