Bhutan Civil Service Main Examination (ICT Category) study guide
Bhutan Civil Service Main Examination (ICT Category) · Work through your exam, one topic at a time.
The Bhutan Civil Service Main Examination (ICT Category) is the competitive written stage through which the Royal Civil Service Commission selects graduate candidates for professional information and communication technology posts in the Bhutanese civil service. It is intended for candidates who already hold a relevant degree and who have cleared the earlier screening stage; it is not an entry-level certification and it does not test vocational tool skills in isolation. The Bhutan Civil Service Main Examination (ICT Category) study guide has 10 sections and about 2,744 words.
01Computer Fundamentals and Operating Systems
A candidate must be fluent in number systems and conversion (binary, octal, decimal, hexadecimal), two's complement representation of signed integers, character encodings (ASCII, Unicode/UTF-8), and the layered structure of a computer: CPU (ALU, control unit, registers), memory hierarchy (registers, cache, RAM, secondary storage), and I/O. Understand stored-program execution: fetch-decode-execute, instruction cycle, addressing modes, and the distinction between RISC and CISC.
260 words, about 1 min02Programming and Data Structures
Candidates need control structures, functions and parameter passing (by value versus by reference), recursion, pointers, scope and lifetime of variables, and static versus dynamic binding. Know the phases of program translation: preprocessing, compilation, assembly, linking, and loading.
269 words, about 1 min03Database Management Systems
Understand the three-schema architecture (external, conceptual, internal), data independence, and the relational model: relations, tuples, attributes, keys (super, candidate, primary, foreign), and integrity constraints (entity and referential). Master relational algebra basics (select, project, join) and SQL: DDL (CREATE, ALTER, DROP), DML (INSERT, UPDATE, DELETE), DQL (SELECT with WHERE, GROUP BY, HAVING, ORDER BY), joins, subqueries, views, and triggers.
263 words, about 1 min04Computer Networks and Internet Technologies
Know the OSI seven layers and the TCP/IP model, mapping protocols to layers: application (HTTP, FTP, SMTP, DNS, DHCP), transport (TCP, UDP), network (IP, ICMP, ARP), and link layers. Understand TCP's connection setup (three-way handshake), reliability, flow control, and congestion control versus UDP's connectionless speed.
244 words, about 1 min05Software Engineering and System Analysis and Design
Understand the software development life cycle (SDLC): requirements, analysis, design, implementation, testing, deployment, maintenance. Compare process models: waterfall, iterative, spiral (risk-driven), prototype, and agile (Scrum, XP, Kanban).
242 words, about 1 min06Cybersecurity and Information Assurance
Master the CIA triad (confidentiality, integrity, availability) plus authentication, authorization, and non-repudiation. Know cryptographic primitives: symmetric (AES, DES), asymmetric (RSA, ECC), hashing (SHA family, MD5 weaknesses), digital signatures, and PKI.
240 words, about 1 min07Web and Mobile Application Development
Understand client-server architecture, the request-response cycle, and the roles of HTML (structure), CSS (presentation), and JavaScript (behavior). Know the DOM, events, forms and validation, responsive design (media queries, flexible grids), and accessibility basics.
228 words, about 1 min08Emerging Technologies (AI, Cloud, IoT, Big Data)
Artificial intelligence spans machine learning (supervised, unsupervised, reinforcement), neural networks and deep learning, natural language processing, and expert systems. Know the difference between training and inference, overfitting versus underfitting, and evaluation metrics (accuracy, precision, recall, F1).
258 words, about 1 min09ICT Policy, Governance and e-Government in Bhutan
Understand Bhutan's ICT governance landscape: the Ministry of Industry, Commerce and Employment (formerly the Ministry of Information and Communications) and the Bhutan InfoComm and Media Authority (BICMA) as regulator, alongside the Royal Government's digital transformation agenda. Know the national ICT policy framework, the e-Government master plan, and flagship services such as the Government-to-Citizen (G2C) portal, Dzongkhag and Gewog connectivity, and the national digital identity initiative.
251 words, about 1 min10General Aptitude
General aptitude tests quantitative reasoning, logical reasoning, verbal ability, and data interpretation. Quantitative topics include percentages, ratios, averages, profit and loss, simple and compound interest, time-speed-distance, time and work, permutations and combinations, probability, and basic mensuration.
