WBCHSE HS Modern Computer Application study guide
WBCHSE HS Modern Computer Application · Work through your exam, one topic at a time.
Modern Computer Application is an elective subject offered at the Higher Secondary stage by the West Bengal Council of Higher Secondary Education, studied across Classes XI and XII alongside a candidate's main stream. It suits students who want a computing qualification on their HS marksheet without committing to a science-only route: commerce and arts candidates take it regularly, and science students often pair it with Mathematics or Computer Science. The WBCHSE HS Modern Computer Application study guide has 8 sections and about 2,701 words.
01Introduction to Computer System and Computer Organization
WBCHSE questions here check that you can name the functional units of a computer system, place them inside the von Neumann model, and explain how a stored program is actually executed. Expect one-mark definitions, short notes on memory and devices, and a small numerical part on capacity or address lines.
353 words, about 2 min02Number Systems and Boolean Algebra
This domain covers positional number systems, base conversion, signed number representation, binary arithmetic, logic gates and Boolean simplification. Questions are usually short and exact: convert, subtract, complete a truth table, prove an identity, or reduce an expression.
367 words, about 2 min03Computer Software and Operating Systems
The paper checks whether you can classify software, describe what an operating system does, compare scheduling policies and recognise deadlock. Expect definitions, comparison tables, short notes on translators and utility programs, and a small scheduling calculation.
312 words, about 2 min04Programming in C
You must read and write short C programs: declarations, operators, control statements, loops, functions, arrays, strings, structures and simple file handling. A typical question gives a snippet and asks for output, or asks you to correct a faulty program.
338 words, about 2 min05Data Structures
Questions ask you to classify data structures, trace stack and queue operations, convert or evaluate expressions, traverse a binary tree, and compare searching and sorting methods by time complexity. Linear structures (array, stack, queue, linked list) arrange data in sequence; non-linear structures (tree, graph) do not.
347 words, about 2 min06Relational Database Management Systems and SQL
You must explain the relational model, identify keys and constraints, justify normalisation, and write or interpret SQL statements using SELECT with filtering, grouping and joins. A relation is a table; a tuple is a row, an attribute a column.
314 words, about 2 min07Computer Networks and the Internet
The domain covers network types, topologies, transmission media, networking devices, protocols and IPv4 addressing. Expect classification questions, device comparisons and a small addressing calculation.
316 words, about 2 min08Web Technology and Multimedia
You must write and read small HTML documents, apply basic CSS, distinguish static from dynamic pages and client-side from server-side scripting, and handle multimedia file formats and size calculations. The Internet is the physical network; the WWW is a service over it.
