Below you will find the entire question list, two complete sample answers so you can judge the quality yourself, the modules the assignment draws from, and the exact steps to receive the full solved set. This internal task, known across the board as the NIOS TMA, is compulsory for every enrolled learner, so an accurate submission is worth the effort.
NIOS Class 12 Computer Science 330 Solved TMA for the 2026 Session
Computer Science is a subject where the assignment mixes two very different skills. Some questions ask you to explain a concept clearly, such as the types of software or what green computing means, while others hand you a snippet of C++ and expect the exact output or a corrected version. A good solved set has to handle both, and this one does.
The file covers the whole assignment as issued for the current session. It runs from the basic computing and office automation questions, through the C++ expression and output tasks, to the database, web design and professional skills items and the final project question with its multiple parts. Every internal choice is answered, so you are never stuck deciding which option to attempt.
You do not have to trust the standard blindly. Two answers are fully worked out further down, exactly as they appear in the file, so you can read the method and decide whether it suits the way you study.
Complete Question List in the Computer Science 330 TMA
Here is the full question paper for the Computer Science 330 assignment, with each internal choice and the lesson it is tagged to. Read it first, then check the two sample solutions to see how the concept answers and the coding answers are handled.

Option B · Lesson 12 to 13, C++ output
Write the output of the following C++ programs: (i) a program that computes the area of a circle for radius 10, (ii) a program that swaps assignments of a = 10 and b = 27 and prints the result, and (iii) a code segment where you underline the errors, correct them and give the output.
Sample Solved Answers from the Computer Science 330 TMA
These two answers are taken straight from the file so you can see the presentation before asking for the full set. One is a C++ expression task and the other is a core object oriented concept question, which together show how both the coding items and the theory items are treated.
Sample 1 · Question 2, Option B · Lesson 12
Evaluating a C++ expression with integer arithmetic
The key idea here is that each division and each remainder uses integer arithmetic, so any fractional part is dropped before the next step.
Given: int a, b = 6, k = 8;
a = b * 3 / 4 + k % 4 − b + 5 / 8
a = 6 * 3 / 4 + 8 % 4 − 6 + 5 / 8
= 18 / 4 + 0 − 6 + 0 (6 * 3 = 18, 8 % 4 = 0, 5 / 8 = 0)
= 4 − 6 + 0 (18 / 4 = 4 in integer division)
= −2
Final value of a = −2.
Sample 2 · Question 5, Option A · Lesson 13
Object and Class, and Polymorphism
Object. An object is an instance of a class that represents a real world entity. It holds data together with the functions that operate on that data. For example, a "Customer" object may interact with an "Account" object in a banking program.
Class. A class is a user defined data type, a blueprint that groups data members and member functions. Objects are created from a class. For example, an "Employee" class can have many objects such as Ram, Shyam or Sita.
Polymorphism. Polymorphism is the ability of a function or operation to behave differently depending on the type of data. For example, the "+" operator adds two integers (3 + 2 = 5) or joins two strings ("a" + "b" = "ab"). It brings flexibility and reusability to object oriented programming.
The remaining items, including the output programs, the error correction task, the data processing cycle and the green computing answer, are worked out to the same standard in the complete file.
How We Prepare the NIOS Class 12 Computer Science 330 Solved TMA
Every answer begins with the source, not a shortcut. Our subject team reads the relevant lesson in the official Computer Science (330) book, confirms the concept the question is testing, and then writes the solution so the reasoning is easy to follow. For the coding questions, the program is actually traced or run rather than guessed, which is why the output values are reliable.
Once a draft is written, a second reviewer checks the logic, the output, and the word limits the paper specifies, such as the forty to sixty word items and the hundred to fifty word ones. Code sections are kept properly aligned so they stay readable when copied into your submission.
Because this subject blends theory and programming, each type is handled on its own terms. Concept answers stay crisp and example driven, while code answers show declarations, steps and the exact printed result. Learners who want lesson notes beside the answers can pair this file with our wider NIOS Study Material for the same subject.
Modules and Lessons Covered in the Computer Science 330 TMA
The Computer Science 330 assignment pulls questions from across the whole book, not one section, so the solved set spans all five modules. The table below lists every module with its lesson range and the specific topics this TMA can test, so you can see exactly where each question comes from.
| Module | Lessons | Topics this TMA draws from |
|---|---|---|
| Module 1: Basic Computing | Lessons 1 to 7 | Computer organisation, input and output devices, plotters for engineering drawings, memory and storage, operating systems, and email search features |
| Module 2: Office Automation | Lessons 8 to 11 | Word processing, spreadsheets and functions, presentations, and MOOCs in online learning |
| Module 3: Programming in C++ | Lessons 12 to 21 | Data types and operators, integer expression evaluation, program output, classes and objects, polymorphism, and error correction in code |
| Module 4: Database and Web Designing | Lessons 22 to 26 | The data processing cycle, database keys, SQL queries, HTML pages, and green computing |
| Module 5: Professional Skills | Lessons 27 to 29 | Assertive communication, professional ethics, and the difference between an entrepreneur and entrepreneurship |
Because the assignment reaches into every module, students often review the wider NIOS Class 12 Syllabus to see how these same topics resurface in the theory paper and the practical exam.
Why Students Trust This Computer Science 330 TMA Solution Set
Trust in a coding assignment comes down to two things. Are the outputs correct, and is the file presented the way a checker wants to read it. This set is built for both, which is why learners come back each session instead of chasing a new source every year.
The answers are original working, not recycled screenshots, so the file reads naturally in your own hand and the C++ stays aligned when you copy it. Students who need more than one subject usually pick everything up together through our main NIOS Class 12 Solved TMA hub, and the same team keeps the standard consistent across subjects.
You also get a real person to talk to. If your study centre uses a slightly different question set or wants a particular format, we adjust the affected answers rather than sending a fixed file and vanishing. That responsiveness is what keeps our Computer Science 330 answers dependable through the whole session.

TMA Format, Practical File and Submission Rules for Computer Science 330
Computer Science 330 is assessed through an eighty mark theory paper and a twenty mark practical, and the TMA is a compulsory internal task you must submit before the theory exam. Those internal marks are among the easiest to secure, because you prepare them at home without exam pressure, which is exactly why a careful submission pays off.
Write the assignment on plain sheets, copy each answer in your own handwriting, and keep the working visible, especially for the C++ items where the steps matter as much as the output. Attempt only the required number of choices, since answering extra parts adds no marks and only crowds the file. Alongside the TMA, maintain your practical file of programs with their inputs and outputs, as it is needed for the practical exam.
Submit the completed set at your study centre before the deadline announced for the session. Deadlines and any question revisions are set by NIOS, so confirm the current assignment against your centre before you submit rather than relying on last year's paper.
TMA and practical deadlines for Computer Science 330 are fixed by NIOS and your study centre for the running session. Always verify the current questions and dates at nios.ac.in or with your centre before submitting.
