BSEH SS Computer Science study guide
BSEH SS Computer Science · Work through your exam, one topic at a time.
The BSEH Senior Secondary Computer Science examination is the Class 12 Computer Science paper set by the Board of School Education, Haryana (BSEH). It is taken by Haryana board students who have chosen Computer Science as an elective in the science, commerce or arts stream, and it serves both as a school-leaving qualification and as a stepping stone towards BCA, B.Tech, B.Sc. The BSEH SS Computer Science study guide has 11 sections and about 3,083 words.
01Computer Fundamentals and Hardware
Computer Fundamentals and Hardware covers the stored-program model, CPU organisation, memory hierarchy, motherboard components, ports and storage. Questions often ask you to distinguish primary from secondary memory, identify a device by function, or calculate capacity and addressable memory.
303 words, about 2 min02Number Systems and Data Representation
Decimal is base 10, binary base 2, octal base 8, hexadecimal base 16. Each positional digit has weight base^position.
279 words, about 1 min03Operating Systems and File Management
Operating Systems and File Management tests process and memory management, scheduling, file systems, paths, permissions and user interfaces. Expect definitions plus small scheduling or path questions.
301 words, about 2 min04Problem Solving and Programming Fundamentals
Problem Solving and Programming Fundamentals tests algorithm design, flowcharts, pseudocode, variables, data types, control structures, functions and testing. The exam rewards precise sequencing and correct dry runs.
286 words, about 1 min05Python Programming
Python Programming tests syntax, indentation, data types, operators, selection, loops, functions, strings, lists, dictionaries, exceptions and basic file handling. Questions often require predicting output or finding an error.
245 words, about 1 min06Data Structures: Lists, Stacks and Queues
Lists, stacks and queues tests linear data structures, their operations, LIFO/FIFO behaviour and applications. Expect output prediction, pointer/front-rear tracking and complexity.
282 words, about 1 min07Database Concepts and SQL
Database Concepts and SQL tests the relational model, keys, integrity, normalisation and query writing. Expect SELECT queries with filtering, grouping, ordering and joins.
285 words, about 1 min08Computer Networks and Internet
Computer Networks and Internet tests topologies, layers, addressing, devices, protocols and services. Questions mix definitions with small IP calculations.
240 words, about 1 min09Web Technologies and HTML
Web Technologies and HTML tests client-server basics, URL structure, HTML document structure, common tags, forms, tables, links and basic CSS. Expect code correction and output.
301 words, about 2 min10Cyber Safety, Ethics and Emerging Technologies
Cyber Safety, Ethics and Emerging Technologies tests threats, protective practices, legal/ethical use and awareness of AI, IoT, cloud, blockchain and big data. Malware types: virus (attaches to files), worm (self-replicates over networks), Trojan (disguised), ransomware (encrypts for payment), spyware (collects data).
274 words, about 1 min11Practical Work and Project
Practical Work and Project tests lab skills: writing and running Python programs, SQL queries, HTML pages, documenting algorithms, testing and explaining your project in a viva. A practical record should show problem statement, algorithm/pseudocode, code, test data, output and conclusion.
