Maharashtra HSC IT Science study guide
Maharashtra HSC IT Science · Work through your exam, one topic at a time.
The Maharashtra HSC Information Technology (Science) paper is a Class 12 board subject taken by Science-stream students under the Maharashtra State Board of Secondary and Higher Secondary Education. It is a school-level elective that builds practical computing literacy: how computers and operating systems work, how web pages are structured and styled, what emerging technologies such as IoT, cloud computing, artificial intelligence and 5G actually mean, how JavaScript adds behaviour to pages, how PHP runs on a server, how relational databases are queried with SQL, and how cyber law and security apply to everyday digital life. The Maharashtra HSC IT Science study guide has 8 sections and about 2,985 words.
01Basics of Information Technology: Units, Number Systems, Software and Logic
Basics of Information Technology is the foundation unit: the data-to-information chain, units of storage, the four number systems and their conversions, character coding, logic gates, and the system-versus-application software split. Most items are one or two marks, so a single wrong positional weight loses the whole answer.
400 words, about 2 min02Introduction to Operating System: Functions, Types and Booting
The operating system is system software that sits between the user, the application programs and the hardware. The exam asks you to name its functions, distinguish its types, explain GUI versus CLI, and describe the boot sequence in the correct order.
375 words, about 2 min03Impressive Web Designing: HTML Structure, Tags and Attributes
HTML describes the structure and meaning of a page; CSS later handles appearance. The exam checks tag spelling, attributes, correct nesting, empty elements, and the rendered output of a short snippet.
372 words, about 2 min04Emerging Technologies: IoT, Cloud, AI and 5G
Emerging technology questions are definition plus application plus one differentiating feature. Four are named in the syllabus: Internet of Things, cloud computing, artificial intelligence and 5G.
378 words, about 2 min05Advanced Web Designing: CSS Rules and JavaScript Behaviour
CSS controls presentation, JavaScript controls behaviour such as validation. The exam asks where each stylesheet type lives, how selectors and specificity work, what the box model is, and how a small script manipulates the DOM or blocks an invalid form.
346 words, about 2 min06Server-Side Scripting with PHP: Forms, Superglobals and Output
PHP runs on the server and sends generated HTML to the browser, so the visitor never sees the source code. It needs a PHP-enabled server such as Apache with the PHP module, commonly installed together in XAMPP.
349 words, about 2 min07Database Concepts and SQL: Keys, DDL and Query Logic
Database concepts and SQL test the relational vocabulary, the difference between key types, DDL versus DML, and your ability to read or write a short query with WHERE, ORDER BY and aggregates. A database is an organised collection of related data; a DBMS is the software that creates and manages it, such as MySQL.
