access modifiers in c#

In addition to correct answer by harish85: all correct, only in the link there are no exact explanation of access specifier application.

I suggest to use a better link: http://msdn.microsoft.com/en-us/library/wxh6fsc7.aspx[^].

Conclusions: all key words you mentioned are, well… keywords and all are modifiers. Some subset of them are access modifiers, listed in the document referenced above. Note that "internal protected" is a special combination of the two, always used together.

Advice: do not provide more access where less access is enough. In particular, do not use public for access within the same assembly; use internal; do not use protected for access within the same assembly; use internal protected.

Basically all above you have given are modifiers.
check this - (Classification of modifiers and their details

1. Yes they're called access modifiers.
2. These are plainly called modifiers.

MSDN - Access Modifiers[^]

sealed - a class that can't be inherited

abstract - a class that MUST be inherited

readonly - a variable that cannot be modified unless done so when the variable is declared or from within the class' constructor(s)

const - a variable that must be initialized when it's defined, and cannot otherwise be changed programatically

Seriously dude, this is all essential and basic knowldeg needed to write code, and beyond that is easily found on google. If this is your version of "research", you should look for a job that adheres more closely to your work ethic.

- Yes, public,private, protected, internal and protected internal are called Access Modifiers.
After reading SA's comments, all these are Keywords basically, also termed as Modifiers. The above list are Access Modifiers, a subset of Modifiers.

- sealed, abstract, readonly and const are called keywords. To add on, you cannot use these keywords to name your variables.
