What is Computer Science?
Computer Science is the study of computers and their applications. It is an interdisciplinary field in which students are introduced to computer science concepts and learn how to apply those concepts to real-world problems.
Computer science students learn how to design, implement and evaluate complex information systems, including software applications and hardware systems. Computer science students also learn about the theoretical basis for computing: computer hardware, software and algorithms. They study database management systems, operating systems, artificial intelligence, computer networks, graphics and web design.
What are the Computer Science courses?
Computer science courses are offered at both the undergraduate and graduate levels. Undergraduate students who major in computer science may focus on either software engineering or computer systems engineering. Graduate students may choose from a variety of areas within computer science such as artificial intelligence or distributed computing.
Courses for Computer Science
There are many different ways to approach computer science, but most courses focus on one or more of these areas:
Data Structures and Algorithms
Algorithms . Algorithms are sets of rules for solving problems. Computer scientists use algorithms to instruct computers how to solve problems in a way that is both efficient and effective.
This course will teach you how to use data structures and algorithms to solve complex problems in computer science. You’ll learn about things like sorting, searching, and graph analysis. You’ll also learn how to implement these algorithms using a variety of programming languages.
Software Design and Development
In this course, you’ll learn how to design software systems with elegant code that can be easily modified by other developers. You’ll learn about object-oriented programming and various other methods for creating robust code. As an added bonus, you’ll also get experience working with open source frameworks like Django and Ruby on Rails!
Web Application Development
Systems . A system is a collection of components that work together to perform a specific function. Systems in computer science include networks, operating systems, and databases. They can be isolated from one another or interconnected by networks.
Programming languages. Programming languages are used by humans to communicate with computers through code. There are many different types of programming languages based on what they’re used for (e.g., web development), who uses them (e.g., business software), or even where they’re developed (e.g., C++).
Which Computer Course is Easiest?
The computer course that is easiest depends on the student. Some students have learned to code by watching YouTube videos, while others have taken classes at a community college. Each student will have different strengths and weaknesses, so it’s important to look at yourself and consider what kind of learner you are.
If you’re an auditory learner, then a video-based course might be the best option for you. You can watch the instructor explain things in their own words, and then listen to some examples of how to apply those concepts in your own life. If this sounds like it would work well for you, then check out Udemy or Coursera for some great options!
If you’re more visual and like seeing things laid out in front of you (rather than reading), then books might be a better fit for your learning style. Books tend to go into more detail about specific topics than videos do, because there’s more space for explanation and examples within each chapter or section. Books also tend to be more structured than videos—which means there are fewer distractions when trying to focus on learning something new!
As said earlier, It totally depends on your ability to grasp knowledge and your area of interest. Same course is easy for some people while some find it very difficult. But if you are new to computers field, I can tell you some courses which are easy and interesting:
- Typing : It is very good to learn typing first.
- MS Excel : If you want to become an accountant or data analyst then this course will be useful for you.
- MS Word : There is no need to explain about this course because everyone knows about MS Word.
- Photoshop Programming : This course is very useful if you want to become a graphic designer in future or if you want to do web designing related jobs.
- Skills : These days everything is digitalized so it’s very important that every person should have basic computer skills like using internet properly (not hacking), making presentations etc.”
- Typing : It is very good to learn typing first.

Which Field in Computer is Best?
Cryptography and Network Security
Cryptography and Network Security is the best field in computer.
Cryptography and Network Security is the field of computer science that focuses on the development of new methods for protecting data from theft, alteration, or other malicious attacks. The field includes work on encryption and decryption, as well as security protocols like SSL/TLS and PGP.
There are two main features of cryptography: confidentiality and integrity. Confidentiality is the process of keeping information secret, which can be accomplished by encrypting it so that only those who have the key to decrypt it can see it. Integrity is the process of making sure that a message’s contents haven’t been altered in transit from one place to another.
Cryptography and Network Security deals with both confidentiality and integrity, as well as other aspects of security such as authentication (ensuring that someone is who they say they are) and non-repudiation (ensuring that someone cannot deny having sent or received something).
This field has a high demand for workers. The reason for this is because the world is becoming more dependent on the internet and therefore more vulnerable to cyber attacks. This makes it so that a lot of people need to learn how to protect themselves from these attacks.
There are many different types of jobs in this field. Some of them include: computer security analyst, computer forensic investigator, ethical hacker, penetration tester and malware analyst.
All of these careers require some type of education but most can be done online via an online school program or even at home through books or tutorials on YouTube.
Cryptography and Network Security is the best field to be in. It is the most lucrative and rewarding field of computer science. The average salary for a Cryptography and Network Security professional is $101,000 per year, with a range between $83,000 and $126,000. This field is growing at a rate of about 19% per year, which means that there will be plenty of opportunities for new graduates in this field. The job outlook for Cryptography and Network Security professionals is good as well; there are currently more than 1 million jobs open in this field.
This field was ranked number one on Glassdoor’s list of top careers in 2018, beating out other popular fields like Software Engineering and Information Technology Management.
