What is Cryptology

Cryptology comes from ancient Greek as words. Cryptology, in its most basic sense, is the science of code. It is based on the encryption of the texts according to a certain system and the receiver decoding this password according to a certain system. The main purpose is the confidentiality of information. Cryptology was used extensively during World War II. The Germans in particular benefited greatly from cryptology. The Enigma machine is an example.

Computer Engineering Internship

Computer Engineering Internship

As in other engineering departments, internship is also very important for Computer Engineering. These internships are usually carried out in classes 2 and 3 of the university. Occasionally, internships are also offered in the 4th grade. My opinion is that the most productive internship classes are in grades 4 and 3. Because students in the 3rd and 4th grades have more knowledge about their departments. They should have more knowledge advantage for internship. In this way they can pass a more efficient internship period. Institutions that have been internship also have a bit of knowledge to understand what has been done. Therefore, the term to be internship is well chosen.

Why is it important to do an internship?

The internship is important to understand the department and the business that we will do, to recognize the sector. We understand the working conditions when doing the internship. We are familiar with the software and hardware industry. We learn from the books that we learned are real. This is very important. So we have an idea about what we can do when we graduate.

We must do our internships absolutely. A good internship can be a preparation for a good future.

Types And Variables C#

Types And Variables C#

We wrote our first code. We printed the 'Hello World' statement, which is standardized in the introduction to coding.

namespace TypesAndVariables




{

class Program
    {

        static void Main(string[] args)




{

Console.WriteLine("Hello World");

}




Console.ReadLine();
}

    }

In the code Console.Readline (); for black screen to close immediately. The program waits for the user to press a key to close.
