Kerala Plus Two Computer Applications (DHSE) · Work through your exam, one topic at a time.
The Kerala Higher Secondary Plus Two Computer Applications course is a state-board subject taken by Class 12 students under the Directorate of Higher Secondary Education (DHSE), Kerala. It suits students who want a practical, application-oriented grounding in computing rather than a purely theoretical computer science track: the syllabus runs from number systems and hardware through networking, web design, office productivity tools, databases and SQL, programming logic with C, and the social and ethical dimensions of ICT. The Kerala Plus Two Computer Applications (DHSE) study guide has 11 sections and about 3,047 words.
01Computer Fundamentals and Number Systems
This domain tests how a computer represents and manipulates data: generations and classifications, hardware/software boundaries, units, and number-system conversions. Expect direct conversion and binary-arithmetic questions rather than definitions alone.
282 words, about 1 min02Hardware, Software and Operating Systems
This domain covers the physical computer, the programs that run it, and the operating system that coordinates resources. Questions often ask you to classify a device or program, identify memory types, or match an OS function to a situation.
296 words, about 1 min03Data Communication and Computer Networks
This domain tests transmission fundamentals, media, topologies, network devices, addressing, and reference models. Expect questions that compare devices or modes, and simple calculations involving bits, bytes and time.
269 words, about 1 min04Internet
This domain covers how the global network is addressed and used: IP and DNS, WWW, URL structure, email, search, and common protocols. Questions often ask you to identify components of a URL or choose the right protocol/service.
261 words, about 1 min05Web Technology and Web Design (HTML/CSS)
This domain tests structure with HTML and presentation with CSS. Expect tag syntax, document structure, links, lists, tables, forms, selectors and the cascade.
299 words, about 1 min06Word Processing
This domain tests document creation and formatting: character and paragraph formatting, styles, tables, headers/footers, page setup, find/replace, and mail merge. Questions often ask for the correct feature or the order of operations.
282 words, about 1 min07Spreadsheet and Presentation Software
This domain covers spreadsheet calculations and presentation design. Expect cell references, formulas/functions, charts, sorting/filtering, and slide elements such as layouts, transitions and animations.
269 words, about 1 min08Database Management Systems and SQL
This domain tests data organisation and querying: keys, relationships, normalization ideas, and SQL for defining and manipulating tables. Expect short queries and questions on constraints and NULL behaviour.
285 words, about 1 min09Programming Concepts and Algorithms
This domain tests problem decomposition, algorithm representation, control structures, arrays, and basic searching/sorting. Expect pseudocode or flowchart reasoning rather than language-specific syntax.
258 words, about 1 min10Programming in C / Problem Solving
This domain applies programming concepts in C: tokens, data types, operators, input/output, control statements, functions, arrays and strings. Expect code reading, error spotting and short program writing.
254 words, about 1 min11ICT in Society, Cyber Ethics and Security
This domain covers ICT applications and the responsible, secure use of digital systems. Expect questions on e-governance, e-learning, e-commerce, digital divide, cyber ethics, threats, safeguards and cyber law.
