Answer:
A(n) <u>Cipher</u> or crypto-system is an encryption method or process encompassing the algorithm, key(s) or crypto-variable(s), and procedures used to perform encryption and decryption.
Explanation:
- Cryptography is such a technique that is used for the secure transfer of the information. We make codes for this purpose.
- Cryptosystem is such a system in cryptography is simply an encryption method that has three algorithms. One algorithm is used for the generation of key, one for encryption and decryption.
- Encryption is a process of converting the information in a data that is not understandable and decryption, this non-understandable data is converted into information so that we can read it.
Answer:
Option 4: Value-returning
Explanation:
In programming, a method is a named section of codes that perform a specific task. This is possible to define a method that return a value after performing its task. This type of method is known as Value-returning method.
For example, we can define a method addition that takes two inputs, x, y and return the summation of x + y to the code that called it. The codes are as follows:
- public static void main(String[] args) {
- int sum = addition(3, 5);
- }
-
- public static int addition(int x, int y){
- return x + y;
- }
A bar code is a series of bars and spaces representing numbers or letters.
<h3><u>
Explanation:</u></h3>
A method that is used for the purpose of representing a data in the form of a picture or image that can be easily understood by the machine. It consists of many lines that has different widths and spaces. They either represent the letter or a number. These are mainly used for the representation of data in the machine understandable format.
For example an UPC-A bar codes has 12 numbers. The numbering system is represented by the first digit. The manufacturer will be represented by the next five digits in it. The product will be represented by the five digits following it. Check digit is represented in the last digit.
