Computer Science or CSE / cse is a high level subject. Every year many students are admitted in this subject. But the problem is that they can't do well in computer science without proper guidelines . So I will try to tell in detail about computer science in this post. I will tell you in detail about the future of computer science, what is taught here and how a student should study. So the subject of our review today, Subject Review: CSE.
A few words before that:
One thing I always say, if you can work hard in any subject then success will come. Because any subject has a future, that subject has been included in the varsity. On the other hand, you have got a very good subject. But you don't have to work. Then you will have nothing in your good subject. Hard work is the mother of happiness. This is not only the truth but also the ultimate reality. Many people think I got a good subject, I got it all. But if you don't work hard, you won't get anything. So your hard work is more important than your subject matter for your success. We basically review the subject to make your effort a little easier. But we would suggest that you reach your success by choosing the right subject, working hard and knowing.
What is computer science?
Many people think that computer science or CSE means ms word, powerpoint, html, css, php, photoshop, website building etc. A friend of mine had to tell me one day, when will we teach MS Word, PowerPoint, Excel! Surprised, I told him, "Friends, don't teach us these things."
Admission test requests, try to know well about each of the subjects you are thinking of studying, do research, be a detective if necessary, find out what is taught there, and get admitted only if you really like them. No subject is number 1 or number 2, which is your choice, even if it is a lower subject in the eyes of people.
Now we will know step by step what is taught in computer science. Then you will decide whether you will study computer science or any other subject.
To study Computer Science (CSE) you need to have 3 skills.
1. Fairly proficient in mathematics,
2. Thinking of doing something new,
3. The mentality and patience to do programming.
Programming:
What is programming:
Various problems can be solved through programming. To solve the problem, a programmer creates programming in the language of the computer. That is, programming is the computer's own language to understand the computer.
Learning programming can build a career in software development, website development. It is also possible to learn programming to solve mathematical problems, rocket motion, quantum mechanics, research in various fields including medical science. The computer we use today is made up of many different programs. Computers work through various instructions. Which is done in the form of coding in the operator.
Most universities first teach C programming (C_Programming_Language). C is called the mother tongue of programmers . Then C ++ or Java is taught as Object Oriented Programming. Development is taught on Android while teaching Java in different universities. Because Java programming is popular for Android development. In addition, as Python has become an important language, Python programming language is introduced in almost all universities. Python is a very popular programming language due to its rich framework and library.
Assembly language was taught later. Here low-level works directly on different parts of memory. The computer saves various data in the form of bits / bytes in memory. Assembly language helps to know how it actually works. It also helps to know assembly language how to save data at hardware level. If you can learn assembly language well, it is possible to create a virus. However, by programming the assembly, different parts of the memory are basically controlled.
Programming language courses are mainly divided into theoretical and lab. In fact most students like the theory class. But whenever the lab is done, they are in a terrible condition. The main work of programming has to be done in the lab and computer science student means programming. So you have to think about how much programming you can do and do more. At first programming may seem scary to you but once you can love programming then you will love programming. If necessary, like your wife, think about programming all the time from morning to noon and night. Make programming a part of your life. Try to solve various problems through programming and try to develop logic.
Projects are usually allowed in the lab so that students have the opportunity to show creativity.
Although there are many more parts in computer science, knowing good programming is basically the main tool to do well in this subject.
Data Structure:
Just think, how does Google, Facebook store so much information? Again, randomly storing data is a problem to find, so there are certain rules for storing data. If we store information according to certain rules, they will not be random. And the data structure helps us in this work. That is, how the data will be structured, how to sort the data are taught in the data structure course.
If documents can be kept in a drawer in order, then it can be found easily by following certain structures and saving data.
Algorithm :
If you give some instructions to the computer, it does it very quickly. But the question is how to do it so fast? How to reduce the size of a large file by compressing? How does Google find the necessary information in the blink of an eye from numerous websites?
If you want to find the answers to these questions then you have to pay attention to the algorithm course.
This is because the solution to such problems lies in the algorithm course. We can call algorithms different steps to solve a problem. Although the university will not show direct problem-solving, this course provides a basis for the techniques needed to solve the problem.
Can teach some common problem solving techniques. It will teach you how to solve different problems with less space and less time on computer.
This course is also divided into Lab and Theory. If you can understand the theory and implement them in the lab, you will understand the algorithm better.
In fact, algorithms and data structures are the foundation of computer science.
Mathematics :
Name of Computer Science Department in Foreign Country -Department of Computer Science and Mathematics. The importance of mathematics can be understood by looking at the name.
Mathematics is required when designing new algorithms or data structures. A problem can be solved in different ways, which method will take up less space in the memory and the program can be done quickly. Mathematics is required for these calculations. The more you can do math, the better your problem solving skills will be.
Curriculum, Probability, Number Theory, Geometry and Linear Algebra are taught in Mathematics. If you can do math well, it will be much easier for you to do well in computer science. Computer science can be a good subject even if one wants to learn real life applications of mathematics.
Operating systems and system programming:
Currently the most popular operating system is Windows. Important course from Operating System Computer Science. This course teaches how the operating system works. Here the internal structure of the operating system is taught. If we work 20 hours at a time on a computer, then the operating system has to create a schedule for 20 hours. Learn how to create a schedule here. Also learn about the management system. Suppose you are allowed to eat a lot of fruit, now it depends on your choice which fruit you will eat first. Similarly, when we give different inputs to the computer, which input the computer will receive first and display the output, the management required for this is taught in this course.
This course deals with Unix / Linux operating system source code.
Database:
Various websites or software store a lot of data. Such as Facebook. Lots of people's data is stored here. How are you talking? Websites or software store this huge amount of data inside a "database". This course is basically about how to input data in the database, how to fetch data from, how to sort data etc. This course may cover different types of databases including mysql, mongoDB.
Artificial Intelligence:
This course is a popular topic for thesis or research. Artificial Intelligence includes all the interesting topics like how to work with robots, how the characters of the game make different decisions on their own, how the computer plays chess . These topics have to be implemented through programming. This course is for you if you are interested in games or robotics.
Data Communications and Networking:
One computer can be connected to many computers. This course teaches how to do these things, how data is exchanged, how data is sent and received on the other end. Glad to know that Network Security is also included in this course. More will be taught LAN, DNS server, IPV-6, cryptography etc.
Job or workplace in computer science
There are endless job opportunities in computer science. There are many fields here. In addition, computer science students can work in any field. E.g.,
1. Various government departments such as Department of Power Development, Rural Electrification Board, Department of Public Health, Department of Disaster Management, Department of Environment, Department of Meteorology will be able to work as engineers in almost all places.
2. Can work as a Software Engineer, Programmer, IT expert in different firms.

10. Mobile companies.
11. Microsoft, Google, Yahoo, Facebook, Intel are all there.
12. Why NASA will be dropped!
13. Besides, if there is an IT firm, where is the problem?
14. Freelancing can be done.
15. You can make apps, games, web as required.
16. By learning programming you can make your hobby robot. Then you can get a job at Google, Microsoft.
১৭. Android Developer
16. Networking.
Also if you are proficient in computer science then you can give yourself an IT firm and not only your own employment but also employment opportunities for many people. But one thing remains, you have to be efficient.
Scholarship in Computer Science
The opportunity to study with scholarship is much more in computer science. High ranking universities like Massachusetts Institute of Technology (MIT), Harvard University, The University of Melbourne, University of California at Berkeley (UCB) offer a lot of scholarships in computer science .
There are also computer science subjects in almost every university. So you can get scholarship in any country. To be sure, the future of the world will be based on technology and science. So there is no chance of reducing the popularity of computer. Therefore, scholarships in this field are easily available in developed countries and every year a lot of students from Bangladesh go abroad to take degrees in this field.
Maybe the writing is getting bigger. We request you to work hard to reach the right destination in whatever subject you study. If you have any questions related to computer science , let us know in the comments or email us.
