WBBSE Madhyamik Computer Application (Optional) study plan

Define and correctly use core vocabulary: bit, byte, word, nibble, register, memory cell, and storage unit, writing each definition in your own words

Convert between binary, octal, decimal, and hexadecimal by hand for 20 mixed numbers, showing every division and multiplication step

Perform binary addition, subtraction (using 1's and 2's complement), and simple multiplication on 15 problems, checking each result by converting back to decimal

Classify the main computer generations and hardware categories (input, output, processing, storage) and place 25 real devices into the correct category

Explain the difference between positional and non-positional number systems with one worked example each

Convert signed numbers to 8-bit sign-magnitude, 1's complement, and 2's complement forms for 12 values, including negative numbers

Compute 1's and 2's complement subtraction for 10 cases and state clearly why 2's complement is preferred in hardware

Distinguish system software from application software and classify 20 named programs into the correct group

Describe the functions of an operating system (process, memory, file, device management, and user interface) with one concrete example of each

Explain the fetch-decode-execute cycle and label the roles of ALU, control unit, registers, and main memory in it

Write step-by-step algorithms in pseudocode for 10 small tasks (sum of n numbers, largest of three, factorial, prime check, digit reversal, and similar)

Draw correct flowcharts using standard symbols (terminal, process, decision, input/output, connector) for 8 of those algorithms

Trace a given algorithm by hand and produce a variable table showing each value change

Translate three flowcharts into actual code in your chosen high-level language and confirm the output matches your trace

Identify and fix three deliberately faulty algorithms containing an off-by-one or missing-initialisation error

Declare and use variables of the standard data types (integer, real/float, character, string, boolean) and explain type conversion with examples

Apply arithmetic, relational, logical, and assignment operators correctly in 15 expressions, stating the result and the order of evaluation

Write programs using if-else, nested if, and switch/case for 6 decision problems, testing each with boundary inputs

Write programs using for, while, and do-while loops for 6 repetition problems, including one nested loop that prints a pattern

Declare a one-dimensional array, read n values into it, and compute sum, average, maximum, and minimum in a single working program

Search an array using linear search and binary search, and state the precondition that binary search requires

Sort an array using bubble sort and selection sort, showing the array state after each pass for a 6-element example

Manipulate strings without built-in shortcuts: find length, reverse, count vowels, check palindrome, and count words in a sentence

Write a menu-driven program that combines an array operation and a string operation, using a loop and a switch

Debug four given programs containing common errors (uninitialised variable, wrong loop bound, array index out of range, string comparison with the wrong operator)

Define network, node, topology, protocol, bandwidth, and IP address, and compare LAN, MAN, and WAN with one realistic example of each

Compare star, bus, ring, and mesh topologies on cost, fault tolerance, and ease of cabling in a short written table

Explain the roles of IP, TCP, HTTP/HTTPS, FTP, SMTP, and DNS, and trace what happens step by step when a browser loads a page by URL

Distinguish the Internet from the World Wide Web and describe the function of a browser, web server, search engine, and URL structure

Identify five cyber-safety threats (phishing, malware, weak passwords, cyberbullying, identity theft) and write the correct defensive response to each

State key digital-citizenship and ethics rules: netiquette, copyright and plagiarism, safe password practice, and reporting mechanisms

Describe five application areas of computing (education, banking, healthcare, e-governance, e-commerce) with one specific real use in each

Explain the practical meaning of cloud computing, artificial intelligence, machine learning, IoT, and big data, and give one everyday example of each

Prepare a lab record format covering aim, requirements, procedure, code, output, and conclusion, and fill it for three earlier programs

Demonstrate file handling basics: open, read, write, and close a text file, and append a line to it

Practise five likely viva questions on your project and write short model answers

Re-solve 25 mixed conversion and 2's complement problems under timed conditions and score at least 90 percent

Rewrite from memory the syntax skeletons for if-else, switch, for, while, array declaration, and string input, then verify against your notes

Complete two full-length mock papers under exam timing and mark them strictly against the syllabus

Revisit every logged error from weeks 1 to 7 and confirm each is now solved correctly without notes

Summarise the whole syllabus on a single revision sheet of key definitions, formulas, and syntax
