NIELIT BCC study plan

Define and distinguish the core IECT building blocks - signal, bandwidth, frequency, modulation, and multiplexing - in your own words with one worked numeric example each

Convert between binary, decimal, hexadecimal, and one's/two's complement representations, and identify the bit-width and range limits of each

Trace a signal path from source through encoder, channel, and decoder to sink, and label where noise, attenuation, and distortion enter

Classify transmission media (twisted pair, coaxial, fibre, radio) by bandwidth, distance, and interference immunity in a comparison chart

Differentiate analog and digital modulation schemes (AM, FM, ASK, FSK, PSK, QAM) and state one practical use for each

Explain multiplexing (FDM, TDM, WDM) and switching (circuit, packet, message) with a diagram of how a shared link is divided

Describe error detection and correction basics - parity, checksum, CRC concept, Hamming distance - and compute a simple parity and checksum example

Summarise the layered roles of the OSI and TCP/IP models and map at least three protocols to their layers

Relate IECT concepts to everyday services: broadcast, mobile telephony, Wi-Fi, and broadband access

Identify internal hardware components (CPU, ALU, registers, cache, RAM, ROM, buses, storage) and state the function and unit of each

Distinguish volatile from non-volatile memory and rank storage types by speed, cost per unit, and typical capacity

Convert between units (bit, byte, KB, MB, GB, TB) and compute file sizes and storage requirements for given scenarios

Describe the boot sequence from power-on through POST, firmware, and OS loading

Classify input, output, and peripheral devices and match each to a typical office use case

Explain the roles of an operating system - process, memory, file, and device management - and demonstrate basic file/folder operations and search

Compare software categories (system, application, utility, open-source vs proprietary) and give two examples of each

Apply safe computing practices: strong passwords, screen lock, backups, malware awareness, and recognising phishing messages

Navigate a desktop environment confidently: create, rename, move, copy, delete, restore from recycle bin, and compress a folder

Identify common file extensions and choose the correct application to open each

Format a word-processor document using styles, headings, page setup, margins, line spacing, tables, and bulleted/numbered lists

Insert and format images, page numbers, headers/footers, and a table of contents, then export the document to PDF

Build a spreadsheet with formulas, relative and absolute references, and at least four functions (SUM, AVERAGE, IF, COUNT/COUNTA)

Create a chart from spreadsheet data and apply sorting, filtering, and basic conditional formatting

Design a presentation of 6-8 slides applying a consistent theme, readable fonts, and minimal text per slide

Explain how the internet works at a user level: IP addressing, DNS resolution, HTTP/HTTPS, and the role of a browser and ISP

Configure and use a web browser effectively: bookmarks, history, downloads, tabs, private mode, and clearing cache/cookies

Compose, send, reply, forward, and attach files in email, and apply good etiquette, subject lines, and CC/BCC correctly

Evaluate a website for credibility using authorship, date, domain, and cross-checking, and identify secure (HTTPS) connections

Perform effective search using operators (quotes, site:, minus, filetype:) and refine results to answer a specific question

Define digital literacy and demonstrate netiquette, digital footprint awareness, and responsible social-media behaviour

Explain key threats - phishing, malware, ransomware, identity theft, social engineering - and match each to a preventive action

Describe data protection principles: consent, purpose limitation, confidentiality, and the individual's rights over personal data

Explain cloud computing service and deployment models (IaaS, PaaS, SaaS; public, private, hybrid) with one example each

Outline emerging technologies - AI/ML, IoT, blockchain, 5G, and big data - stating one benefit and one risk for each

Revise all four domains using spaced repetition, prioritising weak areas flagged in earlier weeks

Complete two timed full-length mock tests under exam conditions and log every wrong answer with its cause

Re-derive the 20 highest-yield facts (unit conversions, OSI layers, formula syntax, threat definitions) from memory without notes

Practise a hands-on office task end-to-end (document, spreadsheet, and presentation) within a set time limit

Consolidate a one-page formula and definition sheet for final pre-exam review
