Kerala Plus Two Computer Science (DHSE) study guide
Kerala Plus Two Computer Science (DHSE) · Work through your exam, one topic at a time.
The Kerala Higher Secondary Computer Science course, examined by the Directorate of Higher Secondary Education (DHSE) at the end of Class 12, is the state's Plus Two elective in computing. It suits students who want a programming-and-systems foundation before engineering, BSc Computer Science, BCA or vocational IT study, and it also counts as a science-subject score for general degree admission. The Kerala Plus Two Computer Science (DHSE) study guide has 10 sections and about 3,067 words.
01Structures and Pointers in C++
The exam tests whether you can model records with struct , access members correctly, and use pointers safely for indirection and dynamic data. A struct groups variables of different types under one name.
295 words, about 1 min02Data Structures: Arrays, Stacks and Queues
Questions test representation, operations, and the LIFO/FIFO behaviour that decides output sequences. A fixed-size, contiguous collection of same-type elements; index starts at 0.
307 words, about 2 min03Linked Lists and Memory Management
This domain tests dynamic node structures, pointer rewiring, and the lifetime rules of heap memory. A node holds data and a next pointer.
313 words, about 2 min04Object-Oriented Programming Concepts
The exam checks whether you can distinguish the four pillars and match each to C++ mechanisms. Class is a blueprint; object is an instance with its own data members.
289 words, about 1 min05Classes, Objects, Constructors and Inheritance
This section tests object lifecycle and the order in which constructors and destructors run. A constructor has the same name as the class, no return type, and runs automatically when an object is created.
312 words, about 2 min06Database Concepts and SQL
Questions cover relational terminology, keys, integrity rules, and single-table SQL with aggregates. A relation is a table; a tuple is a row; an attribute is a column.
297 words, about 1 min07Web Technology: HTML, CSS and JavaScript
The exam tests document structure, presentation rules, and client-side behaviour, including form validation. HTML describes structure with elements and attributes: <html , <head , <body , headings, lists, links, images, tables, forms.
301 words, about 2 min08PHP and Server-Side Scripting
This domain tests how a server executes PHP, handles form data, and interacts with databases securely. PHP runs on the web server; the browser receives only the generated HTML, never the PHP source.
308 words, about 2 min09Computer Networks and Internet Basics
The exam tests network components, addressing, protocols, and how a URL becomes a page. A network links devices to share resources.
300 words, about 2 min10ICT, IT Applications and Emerging Trends
This domain tests how information and communication technology is applied in society and the vocabulary of newer technologies. ICT covers hardware, software, networks, and services used to create, store, process, and exchange information.
