BSEH SS Computer Science study plan

Label the internal components of a computer (CPU, ALU, control unit, registers, cache, RAM, ROM, buses) and state the function of each in one sentence

Distinguish primary from secondary storage and compare HDD, SSD, and optical media on speed, capacity, volatility, and typical use

Classify input and output devices and explain the role of device drivers in mediating hardware access

Convert between binary, octal, decimal, and hexadecimal by hand for at least 20 mixed numbers, showing the working

Perform 8-bit two's complement representation of signed integers and compute the range of values for n-bit signed and unsigned storage

Describe the boot sequence from power-on through firmware, bootloader, and kernel handoff, and name where each step can fail

Compare process scheduling, memory management, and virtual memory in terms of what problem each solves

Create, move, rename, delete, and set permissions on files and directories using both a GUI and command-line equivalents, and explain absolute versus relative paths

Write algorithms as pseudocode and as flowcharts for at least three everyday tasks, using sequence, selection, and iteration correctly

Trace a given algorithm by hand and predict its output for three different inputs, including one edge case

Write and run Python programs that use variables, the four core data types, input/output with type casting, and formatted printing

Control program flow with if/elif/else, while, and for loops, including nested loops and break/continue

Define functions with positional, keyword, and default parameters, and explain local versus global scope with an example of each

Manipulate strings using slicing, indexing, and at least six built-in string methods

Handle runtime errors with try/except and identify the exception type raised by common mistakes such as int('abc')

Create, index, slice, append, insert, remove, and sort Python lists, and predict the result of each operation before running it

Implement a stack using a list with push, pop, peek, and isEmpty, and state the LIFO rule in your own words

Implement a queue with enqueue and dequeue, and explain why a naive list-based queue differs in cost from collections.deque

Trace stack and queue contents step by step for a given sequence of operations and give the final state

Convert a simple iterative solution into a function that uses a stack or queue, and justify the choice

Explain tables, rows, columns, primary keys, foreign keys, and candidate keys using a small schema you design yourself

Write SELECT queries with WHERE, ORDER BY, DISTINCT, and aggregate functions including GROUP BY and HAVING

Write inner and left joins across two or three tables and predict the row count of each result before executing

Classify SQL statements as DDL or DML and use CREATE, INSERT, UPDATE, and DELETE on a scratch database

Normalize a flat table to third normal form, stating the anomaly removed at each step

Map the layers of the TCP/IP model to their functions and name one protocol at each layer

Distinguish IP addressing concepts: IPv4 versus IPv6, private versus public addresses, and the roles of DNS, DHCP, and NAT

Explain how a URL resolves to a rendered page, ordering the steps from DNS lookup through HTTP request and response

Write valid HTML using document structure, headings, lists, tables, links, and images, and use forms with common input types

Apply CSS selectors and the box model to style a page, and separate structure from presentation

Identify phishing, malware, ransomware, and social engineering attacks and state one concrete preventive practice for each

Explain strong password and authentication practices, including multi-factor authentication and why password reuse is dangerous

Describe safe browsing and data protection habits: HTTPS indicators, permissions, backups, and handling personal data responsibly

Summarize the current state of at least three emerging technologies (for example AI, cloud computing, IoT, blockchain) with one realistic benefit and one risk each

Plan the practical project: define scope, list features, sketch the interface, and break work into tasks with time estimates

Build the project end to end, integrating Python logic with either a database or a styled web front end, and fix all errors found during testing

Write a short project report covering aim, design decisions, code or markup listing, test cases with expected versus actual results, and limitations

Complete two full-length timed practice papers under exam conditions and mark them against the domain weightings

Re-derive weak areas from the marked papers and redo at least 20 questions per weak domain until accuracy exceeds 80%

Recite from memory the key facts for each domain: unit conversions, SQL clause order, OSI/TCP-IP layers, HTML tag rules, and Python syntax traps
