I would a Standard Access control List
There are two common access lists: The standard and extended access list. With the standard access list, it creates filters only on source addresses and is commonly used for server-based filtering. They are not as powerful as extended access lists. Standard Access lists are typically used for restricting access to a router through HTTP and HTTPS.
A device connected to the internet is known as a Node.
Small programs stored on the harddrive that provide basic functionality for he devices listed would be called Hardware Drivers.
I hope this helps!
Explanation:
In simple English, an array is a collection.
In C also, it is a collection of similar type of data which can be either of int, float, double, char (String), etc. All the data types must be same. For example, we can't have an array in which some of the data are integer and some are float.
