Answer:
I dont know about 1800 words but I sure can tell you abit about array
Explanation: Array in simple sense refers to a collection of similar data. It holds data which is homogeneous in nature, meaning they are all alike. The use of array provide a lot of advantages in the fields of computer programming. When you declare a variable for an array, you can store as much data as you wish in the same variable without having to declare many variables. A 2X2 dimensional array can also be used in programming which represents matrices as well. The search process in an array too is really convenient and time saving. Also in an array, accessing an element is very easy by using the index number.
The benefit of getting information from a government website is that the information can be trusted. Government wouldn't post just about anything on its website - if it wants to share something on its webpage, it has to be a correct and reliable information, and something that you definitely can trust. No other website can guarantee that the way government websites can.

DES is a commonly used symmetric encryption
A) is a commonly used symmetric encryption
<u>Explanation:</u>
DES stands for Data Encryption Standard. It is a symmetric key algorithm and is used for encrypting electronic data. It was developed in 1975. DES is one of the oldest encryption standards to be used in the industry.
The algorithm takes 16 rounds of permutations in order to encrypt data. But now, with the advent of technology, as new algorithms have been designed and put in use, DES is less preferable.
In the process of key generation, some keys generated sometimes turn out to be weak and hence are prone to attacks. If not for the weak keys generation, DES works perfectly fine and is an effective algorithm to encrypt data.
