What is Computer Science?: Course Fees 2026, Subjects, Top Colleges, Admissions

Computer Science is a STEM specialization. It combines theory and practical applications of computational systems, programming, data structures, algorithms, software, hardware, etc. Popular CS picks are BSc/ BTech CS at undergraduate level and MSc/ M.Tech CS at postgraduate level. 

Computer Science is now a necessary part of modern life as a result of how swiftly technology is developing and how much more frequently it is used. This has increased the demand for programmers, coders, data translators, and experts in IT solutions and application systems from the IT and software industries. This provides Computer Science students with a unique experience and a variety of job opportunities following graduation. So, the top-demanding Computer Science courses are given below:

• BCA
• BSc in Computer Science
• BCA+MCA (Integrated)
• BE Cloud Computing
• MSc Computer Science
• BTech CSE with specialisation in Full Stack Development
• BTech CSE with specialisation in Artificial Intelligence
• BSc Information Technology

Yes, you can. Many private colleges offer Computer Science to candidates who are from the PCB stream. However, if such candidates wish to enroll on a Computer Science course in a government college, admission can be tough. The candidates are advised to go through the admission requirements of their desired colleges before applying for Computer Science admission. Also engineering courses could be off limits for students who did not have maths in class 12th.

You can consider Computer Science courses to be ideal if you want to get into tech, academia, research,  plan for a master's too. The core focus could vary across course types but some general topics are -  Software and Algorithms, Application, Engineering and  Hardware. CS specializations include AI, ML, Cloud Computing, Cyber Security etc.

With good skills, experience/ projects in resume you can apply for roles like - Software engineer, Web developer, Data scientist, Database, Cybersecurity analyst, Data analyst etc. There is good scope in research & academia as well. Though a few places might prefer a pure tech degree.

You can aspire to work in areas like -  IT firms, startups or academia abroad. Make sure you meet language proficiency test, additional qualifications, work visa, etc. If you are planning to pursue MS abroad, note that some universities may prefer BTech for that. 

YES, it is most possible to pursue a MSc Computer Science without a BSc Computer Science degree. In general, institutes do not limit students to entering MSCS programs without a bachelor in CS.

The reason here is the relevant subjects you have taken in your bachelor's. CS uses computer and scientific principles to deal with software systems and computational functions.

As a commerce student wanting to transition into Computer Science courses, you have the following options.

You can do a BSc Computer Science. Note that some universities require you to have a maths background for that.

You can go for BCA. Again, make sure you meet the college requirements, as some may require you to have Computer Science and Maths in class 12.

Though engineering courses accept admissions from a science background only. Sometimes after a BCA/BSc, you may be eligible for lateral entry into the second year of a BTech. This totally depends on the flexibility of the college guidelines.

The 'better' course depends on various factors. Some of the core differences between the two are covered below:

BSc Computer Science: A 3-year UG academic degree in Computer Science. Usually preferred to get into research & academia. Though one can also work in roles like developer, analyst, or engineer after this course if they have a relevant skillset.  Though the curriculum has both theory & lab work included, it is still more of a theory-driven course focused on CS fundamentals. BSc CS has a shorter duration, an easier entry, and an affordable cost.

BTech CSE: By the name, a 4-year tech degree. Comparatively more advanced & application-based approach. Probably the most preferred for tech roles (ofcourse if you have the skills). Extensive labs works in the curriculum. The fee structures are usually high with highly competitive entry in top colleges. A bit more acceptable by foreign companies & universities for pursuing a Master's.

Relevant skills, experience and projects can lead you to job roles like - Software engineer, Web developer, Data scientist, Database, Cybersecurity analyst, Data analyst etc. Or you can go into research & academia as well. You can either go for a tech degree like BTech CS, M.Tech CS or academic degrees like BSc, MSc.

The decision can be quite overwhelming for students straight out of class 12.

To know for sure, ask yourself if the subjects are resonating with you. If you have a genuine interest or not. One can pursue a course in CS if he/ she has keen interest in -

Computer Science, Computer Applications, basics of top Programming Languages, Data Analysis, Problem-solving ability, Logical Reasoning, Numerical Ability, etc.

Both are closely related fields. Simply put - Computer Science is the creation of software & hardware by using programming. IT is just the selection of the proper software or hardware for the task. CS is basically working with the physical component of computers like processors, supercomputer and dealing with the software which runs them basically making hardware and software and IT deals with selecting proper software to run the machines. 

Some of the most popular Computer Science Engineering entrance exams in India are mentioned below -  
CUET, LPU NEST, JEE Main, JEE Advanced, GATE, MHT CET, Andhra Pradesh EAMCET, TS EAMCET, KCET, VITEEE and SRMJEEE.

In difficulty the Computer Science entrance ranges from moderate to high. The difficulty level is based on Individual capabilities, Prior knowledge and syllabus. Candidates need to get a hold of the syllabus properly to keep their preparation on point and save their time. Attribute more effort to topics with more weightage. The population estimated to take that particular exam also plays a role in determining your rank and competition to get into the top colleges of the country.

Research further on these courses and know which entrance exams you can aim for as per the respective course choices. Some of the top courses one can opt for after class 12 are

The better course is subjective. It's just that you need to see what works for you and aligns better with your interests and goals. On one hand there is Computer Science (CS) is the study of all aspects of computers with a focus on secure software systems. 
On the other hand Computer Science Engineering (CE) is a separate educational path focused on designing and developing secure hardware systems, even though the terms are frequently used interchangeably. 

Computer Science focuses on Coding or Computer Programming in developing computer programs and applications. Most businesses have a team of IT specialists in charge of managing their IT assets and infrastructure. CS basically creates and develops the software that IT specialists use and maintain. 

Some of the common Computer Science elective subjects are covered below

No, Computer Science cannot be pursued without Class 12 Science stream. It is not possible to pursue Computer Science without having a traditional Science background. Though many CS programs and courses are designed to accommodate students from various academic backgrounds yet having a math background might give you an edge in understanding various concepts during higher studies.

As per the most common Computer Science eligibility criteria candidates seeking admission to Computer Science courses at the undergraduate level should have cleared Class 12 with Science subjects.

Although there are numerous entrance exams for computer Science courses in India. The most common entrance exam for a computer Science undergraduate course is CUET UG in India. A generic overview of the syllabus topics that are supposed to be covered while preparing for the CUET entrance exam for CS courses is mentioned below -
