Punjab PSEB SS Computer Science study plan

Define computer fundamentals vocabulary in writing: hardware versus software, input-process-output cycle, and the four primary functional units of a computer, giving one concrete example for each unit

Classify ten common devices (keyboard, scanner, plotter, touchscreen, modem, SSD, and others) as input, output, storage, or processing, and justify each classification in one sentence

Compare primary memory and secondary memory across at least four attributes (volatility, speed, capacity, cost per unit) in a self-made table

Trace how a single keystroke travels from input device to displayed character, naming each component involved in order

List the main motherboard components and state the function of each in a single line

Convert between number systems by hand: binary, octal, decimal, and hexadecimal, completing at least twenty conversions in each direction without a calculator

Perform binary addition, subtraction, and multiplication on 8-bit numbers, showing borrow and carry steps explicitly

Compute 1's complement and 2's complement of given 8-bit binary numbers and use 2's complement to subtract two numbers

State the truth tables for AND, OR, NOT, NAND, NOR, XOR, and XNOR gates from memory and draw each symbol

Simplify three small Boolean expressions using algebraic rules and verify each simplification with a truth table

Describe the fetch-decode-execute cycle in sequence, naming the role of the program counter, instruction register, ALU, and control unit at each stage

Differentiate RAM and ROM types (SRAM, DRAM, PROM, EPROM, EEPROM) by volatility, erasability, and typical use

Explain cache memory, registers, and virtual memory, and rank them with RAM and secondary storage by speed and cost

Identify at least six secondary storage media and compare them on capacity, access speed, portability, and durability

Define operating system functions and distinguish single-user, multi-user, multitasking, and real-time operating systems with one example each

Convert algorithms into flowcharts using correct standard symbols for terminal, process, decision, input/output, and connector

Write pseudocode for five common problems: sum of n numbers, largest of three numbers, factorial, prime check, and reverse of a number

Trace a given flowchart with sample inputs and produce the exact output, documenting variable values at each decision point

Distinguish syntax errors, logical errors, and runtime errors, and give one concrete example of each in a short program

Solve ten previous-style questions on programming logic under timed conditions

Explain the characteristics of a good algorithm (finiteness, definiteness, effectiveness, input, output) and apply them to critique two flawed algorithms

Describe the role of a compiler, interpreter, and assembler, and state two differences between compilers and interpreters

Write short programs in a PSEB-syllabus language covering input, output, conditional statements, and loops

Identify and correct at least five buggy code snippets, stating the error type and the fix for each

Define constants, variables, data types, and operators, and evaluate mixed expressions respecting operator precedence

Define database, DBMS, table, record, field, primary key, and foreign key, and give an example schema for a school library or student record system

Write SQL statements for SELECT, WHERE, ORDER BY, INSERT, UPDATE, and DELETE on a small two-table schema

Explain data redundancy and inconsistency, and describe how normalization to first and second normal form reduces them

Differentiate DDL and DML commands and classify at least eight SQL commands accordingly

Describe the layered model of computer networking, naming the function of each layer and one protocol associated with it

Define computer virus, malware, worm, trojan, and ransomware, and state one prevention measure for each

Explain symmetric versus asymmetric encryption and the role of digital signatures and firewalls in protecting data

Describe cybercrime categories relevant to the syllabus and list safe-practice rules for passwords, phishing, and social media use

Explain the terms hacking, cracking, and ethical hacking and distinguish them precisely

Outline intellectual property concepts: copyright, patent, trademark, and software piracy, with one example each

Consolidate all prior weeks into a single index of formulas, definitions, truth tables, and SQL syntax for rapid review

Complete two full-length timed mock papers under exam conditions and score them strictly against the marking scheme

Identify the three weakest sub-topics from mock results and rewrite condensed notes for each

Practice at least twenty short-answer and definition questions aloud or in writing within time limits

Review flagged uncertain items and confirm each against the PSEB textbook so no unresolved gaps remain
