Most Important Topics For GATE CSE Preparation 2022

‘Graduate Aptitude Test in Engineering’ popularly known as GATE is one of the most sought-after competitive test offered by top-tier institutes and colleges across India. It is conducted for Master of Engineering (ME), Master’s in Technology (M. Tech), and Ph.D. admissions in top-tier Indian Institute of Technology (IITs), National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs), and other institutes/universities across India.
GATE also acts as a passport to fly abroad for higher studies and secure jobs in the top Indian PSUs. Some of the established PSUs that use the GATE score for hiring include ONGC, HPCL, BHEL, DRDO, BARC, GAIL, SAIL, NHPC, HAL, BEL, etc. Every year nearly one million candidates enroll for the GATE examination thereby making it one of the toughest entrance competitions in India. You can even fly abroad for higher studies in countries such as Germany and Singapore or pursue fellowship programs.
IIT Kharagpur will conduct GATE Exam 2022 and has recently issued an official GATE 2022 notification on its site in August 2021. The notice will display information regarding the important dates, registration process, application form & fees, GATE Syllabus and GATE exam pattern, etc. Candidates can visit the official site to get a complete idea of the GATE examination or follow the Ekeeda blog with the latest updates and trends.
IIT Kharagpur GATE 2022 has recently announced that it will include two new designing papers, namely - Naval Architecture and Marine Engineering and Geomatics Engineering.  With the inclusion of two new papers, GATE 2022 will now have 29 papers/subjects in total. A year ago, two new papers were included by IIT, Bombay - Environmental Science and Engineering (ES), and Humanities and Social Science (XS). To get complete GATE Syllabus candidates can read

Since candidates are allowed to appear for two papers (only a specified set) of the 29 papers, they should carefully make a choice of the papers they wish to appear. Candidates are advised to appear in the papers appropriate to the discipline of his or her qualifying degree. However, they are also free to choose any paper according to their future plans based on the GATE eligibility criteria of the institute/university they wish to seek admission into.
A total of 8,58,890 candidates had applied for GATE 2021 out of which 6,85,088 candidates were eligible to appear GATE 2021. Out of these, 128797 approx were able to qualify for the GATE examination. Thus, you can imagine how tough the GATE exam is and what is the level of competition for the exam. The GATE 2021 results have already been announced and several applicants have met their academic goals and others have also begun preparing for GATE 2022.
Computer Science is one of the most popular streams in GATE and we’re going to tell you about some important topics you need to study in Computer Science for the GATE exam if you wish to secure a spot on the merit list.

Our blog will help you in your
GATE CSE preparation journey in 2022. So, let’s start exploring the important topics of the GATE CSE syllabus 2022. In this blog, we will try and cover every GATE CSE important topic subject wise for you:
General Aptitude –
It’s a common section across all subjects/papers and it's amongst the highly important topics for GATE. It carries 15 marks in the GATE examination. These fifteen numbers are distributed as follows – 5 questions with 1 mark and 5 questions with 2 marks.
In the GATE CSE examination, the General Aptitude section consists of two parts: Verbal Ability and Numerical Ability.
In Verbal ability, we must study sentence completion, English grammar, verbal analogies, commands, word groups, verbal deduction, and critical reasoning, according to the GATE CS syllabus.
Besides, numerical estimation, numerical calculation, data interpretation, and numerical reasoning must all be covered in Numerical ability.
It’s advisable for the general aptitude section in GATE CS, you can go over the last 10-12 years' previous year questions. It will give you a complete idea of the types of questions that may appear in the GATE CS examination.

Engineering Mathematics -
Engineering mathematics is a basic subject for GATE paper and the following are some of the important topics from the GATE CSE syllabus are –
Linear Algebra: LU decomposition, Matrices, systems of linear equations, determinants, and eigenvectors.
Probability: Bayes theorem, Random variables, Uniform, normal, exponential, Poisson and binomial distributions, and standard deviation, Conditional probability and Mean median, mode.
Calculus: Differentiability, limits, and continuity, Integration, Maxima and minima, Mean value theorem.
Discrete Mathematics: Combinatory: generating functions, counting, recurrence relations. First-order logic and Propositional.
Groups, sets, lattices, functions, partial orders, and relations.
Graphs: coloring, matching, connectivity.
Experts say, ‘The only way to prepare for Engineering Mathematics is to practice as much GATE previous year question papers as possible. This is an important topic for GATE computer science and it’s a part of the subject-specified paper. If worked hard and plan properly you can get full marks in this subject.
The only way to prepare for this subject is to practice previous year's questions; this is an important topic for GATE computer science because you can get full marks in this subject.

Operating systems –
It is one of the high-scoring subjects that will help you get maximum marks in the GATE CS Examination. Important topics in an operating system subject for the computer science GATE 2022 exam include:

  • Memory management and virtual memory

  • Concurrency and synchronization and Deadlock

  • CPU scheduling

  • Scheduling Algorithms

  • Semaphores

  • Paging and Page replacement algorithms

  • Processes, threads, interposes communication

  • File systems

Out of these topics, paging and page replacement algorithms will receive the maximum weightage. Therefore, it's important to have a better understanding that is properly described when each subject is taken concept-wise.
Digital Logic
Combinational Circuits, Logic Families, Minimization, Semiconductor memories, Dat Convertors, microprocessors, and Counters are the most important topics in Digital Logic. The topic of Combinational Circuits receives the maximum weightage for the GATE examination. The topics Sequential Circuits might also have good weightage and generate questions at any stage. The subjects – fixed and floating-point registers, number system, – will have simple questions.
DBS - Database Management Systems
The topics in this subject are simple and high scoring relative to the other subjects. With a little practice and understanding, you can lock the marks in GATE exam. Important topics for DBS GATE computer science include:

  • ER model
