GATE, Difference Between Articles Assist in Preparation – Here Is How

The General Aptitude Test for Engineering (GATE) examination is one of the most prestigious exams conducted in India. Every year, millions of tech aspirants look forward to cracking it to secure the best seats in IITs, NITs, etc. But the scores of this exam are not just a criterion of preference for getting admission to the top-most universities, it also acts as a prerequisite for getting a safe spot in Public Sector Undertakings (PSUs), cracking various other exams like ONGC, DRDO, ISRO, etc.

Due to the wide range of benefits that an aspirant can get by cracking the exam, the competition is way too high. If you are also an aspirant, then you must cover the entire syllabus, including all the basics concerning every topic and sub topic. Checking out the GATE difference between articles and full-form articles will help clarify these doubts. And while students often check out the full forms and explanations of individual topics, they often ignore the difference between articles. In this article, we will discuss why these are important.

Benefits of Referring to Difference Between Articles

Individuals might be confused with some basic terms used in day-to-day applications. Being tech enthusiasts, they must know the correct usage of these terms. In such cases, the difference between articles would help when two terms sound confusing, such as the difference between malloc and calloc, primary key and foreign key, GPS and GPRS, etc.

Similarly, you might also get confused with some terms during the exams. Now, the sole purpose of the GATE exam is to test your knowledge of the concerned subject. And a candidate who has cracked the exam is expected to be aware of all the basics. So you can avoid getting confused with the terms by checking these articles. It will help you clear the GATE exams with much better scores.


Just like we discussed in the previous section, various technical terms might create confusion in the minds of readers as well as listeners. Here are a few common examples:

Difference Between Structure and Union

They are both container data types, and they are capable of holding any data type. There is one very major difference between structure and union. The union has the same memory location for all of its members, while the Structure possesses separate ones for the same purpose.

Structures basically represent a record. All of its elements are stored in contiguous memory locations. A Structure type, the Variables, can store more than one data item from ranging data types all under one name. A user can define a Union using many members, but only one of them holds a value at any given time. It provides you with an efficient way of using a single memory location for various purposes. Thus, varying objects can share a similar location. A user must deploy the struct statement to define a structure and the union statement for defining a Union.

Difference Between Malloc and Calloc

Both- malloc() and calloc() functions are used for dynamic memory allocation in the C programming language. The main difference between malloc() and calloc() is that calloc() always requires two arguments, and malloc() requires only one.

The malloc is also known as the memory allocation function. Malloc() dynamically allocates a large block of memory with a specific size. It returns a void type pointer and is cast into any form. The calloc() function allocates a specific amount of memory and initialize it to zero. The function can be cast to the desired type when it returns a void pointer to the memory location.

Other Resources You Must Have

Here are a few more resources that you must keep handy when you prepare for the GATE exams in 2022:

  • GATE offline and online study materials from trusted sources to cover the syllabus – including books, ebooks, articles, MCQs, full forms, individual topic explanations, etc.
  • GATE syllabus to narrow down the study materials and study what is more important.
  • GATE notes from the previous year and running notes to help with the preparation on the go.
  • GATE previous years’ question papers, from at least 4 years, to gauge the pattern of questions and exam’s difficulty.
  • GATE sample papers to practice in an exam-like environment.
  • GATE mock tests for marking the current level of preparation and understanding the topics that need more focus.

Cracking an exam as difficult as GATE is no layman’s job. Not only is the competition high but you also must ensure that you secure a spot on the merit list to get better employment and educational opportunities. If you wish to crack the GATE exam, be ready to buck up and study hard! All the best for your future!
