What do the Grade 11 Information Technology cards cover?

16 cards across 6 chapters of the national textbook: Information Systems and Its Applications, Emerging Technologies, Database Management, Web Development, Hardware Troubleshooting and Preventive Maintenance and Fundamentals of Programming. You can take any chapter one card at a time on the page itself.

Is there a national exam in Grade 11?

No. Ethiopia sets national exams in Grade 6, Grade 8 and Grade 12 only. These cards are for your school's own exams, and for the national exam that comes a few years later.

Where do these cards come from?

They are drafted from Grade 11 Information Communication Technology, the Ministry of Education textbook for this grade. A second pass that cannot see the chapter then re-derives every formula, constant and table row, and anything it cannot confirm is held back instead of published.

Yes. Every card here is free to read and the printable sheet is free to download. Neither needs an account.

When was this last checked?

30 August 2026. Cards arrive chapter by chapter, and the line under each one says when that card was last read through.

Information Systems and Its Applications

DIKW HierarchyReference tableData · Information · Knowledge · +1

Level	Description	Example
Data	Raw facts without inherent context or meaning	100, +251...
Information	Data processed and structured to answer who, what, or when	Phone number: +251...
Knowledge	Understanding patterns and skills acquired to think and act	Knowing how to ride a bicycle
Wisdom	Highest level of intelligence to make wise decisions and judgments	Making sound life decisions

When you use it

Use this to distinguish between the four stages of human understanding from raw facts to judgment.

Watch out

Do not treat raw numbers or words as information until context or meaning is added to them.

Five Components of an Information SystemReference tableHardware · Software · Data and Information · +2

Component	Function	Examples
Hardware	Physical digital devices for storage, processing, and communication	Computers, servers, networks
Software	Instructions that command the computer hardware	OS, DBMS, application programs
Data and Information	Critical recorded facts stored in databases for reporting	Daily sales, student records
People	Qualified technical personnel who operate and manage the system	System administrators, users
Procedure	Policies and step by step methods to operate and maintain the system	Access rules, update policies

When you use it

Use this when identifying or categorizing the essential parts required to run an Information System.

Watch out

An Information System is not just hardware and software; people and procedures are equally required components.

Emerging Technologies

Branches of Artificial IntelligenceReference tableMachine Learning · Robotics · Natural Language Processing · +1

Branch	Core Focus	Application Examples
Machine Learning	Algorithms learning from sample data without explicit programming	Fraud detection, spam filtering, recommendation systems
Robotics	Machines substituting physical human labor and hazardous tasks	Car assembly lines, vacuum cleaners, space exploration
Natural Language Processing	Enabling computers to understand spoken and written human language	Virtual assistants, machine translation, sentiment analysis
Expert Systems	Software programs emulating human experts to solve domain problems	Medical diagnosis (MYCIN), financial investment analysis

When you use it

Use to categorize AI technologies into their specific subfields and match them with real-world applications.

Watch out

Do not treat Machine Learning as conventional programming; it trains on data patterns rather than executing hard-coded step-by-step instructions.

Components of an Expert SystemReference tableUser Interface · Knowledge Base · Inference Engine

Component	Role and Description
User Interface	Accepts queries from users and displays recommendations
Knowledge Base	Stores expert domain knowledge organized in if-then-else rules
Inference Engine	Acts as the brain to reason and deduce answers using the knowledge base

When you use it

Use when identifying the three core structural components of an expert system and their specific functions.

Watch out

The inference engine derives conclusions, but it relies entirely on the quality and completeness of the rules stored in the knowledge base.

Mistaking Virtual Reality for Augmented RealityCommon mistake

When you use it

Review when answering questions about user interaction modes, sensory simulation, and display hardware.

Watch out

Students often claim VR displays information over the real world. In fact, VR shuts out the physical world completely, while AR overlays digital graphics onto the physical world.

Database Management

File-Based versus Database ApproachReference tableData Storage · Data Redundancy · Data Consistency · +1

Feature	File-Based Approach	Database Approach
Data Storage	Separate isolated files	Single central repository
Data Redundancy	High duplication across departments	Controlled and avoided
Data Consistency	Low, risk of contradictions	High, centralized updates
Security and Sharing	Isolated and program dependent	Shared via DBMS with user access rights

When you use it

Use when comparing traditional file management limitations with modern DBMS advantages.

Watch out

File-based modifications require changing the application program, whereas DBMS provides data independence.

Primary Key and Foreign Key RulesRule

When you use it

Use when defining unique row identifiers or creating navigational links between related tables.

Watch out

A foreign key in a child table must match the data type and values of the primary key in the related parent table.

Query Selection Criteria MismatchCommon mistake

When you use it

Use when filtering records using specific conditions in MS Access Query Design.

Watch out

The criteria value must match the exact format stored in the table. Typing Male when the table uses the abbreviation M returns zero results.

Relational Model and ERD NotationReference tableEntity · Attribute · Tuple (Record) · +1

Concept	Relational Database	ERD Representation
Entity	Table	Rectangle
Attribute	Field (Column)	Ellipse
Tuple (Record)	Row	Instance
Relationship	Foreign Key Link	Line

When you use it

Use when converting an Entity Relationship Diagram into relational database tables or identifying table components.

Watch out

Do not confuse records (tuples/rows) with attributes (fields/columns).

Web Development

HTML Hyperlinks and Page NavigationRule

When you use it

Use the anchor tag to link to external websites, local files, or specific sections on the same page.

Watch out

Internal section links require a hash symbol before the section name in href, such as href="#section_one".

HTML List Types and Bullet FormatsReference tableOrdered List · Unordered List · Description List

List Type	Tag	Type Attribute Values
Ordered List	<ol>	1, I, i, A, a
Unordered List	<ul>	disc, square, circle
Description List	<dl>	<dt> (term), <dd> (description)

When you use it

Use to display numbered, bulleted, or term-definition lists on a webpage.

Watch out

Ordered lists use Arabic numerals by default, while unordered lists default to disc.

Void Elements and Missing Required AttributesCommon mistake

When you use it

Reach for this card when working with standalone HTML tags like line breaks, images, and horizontal rules.

Watch out

Void elements like br, hr, and img do not have closing tags, and img will fail to render without the src attribute.

Hardware Troubleshooting and Preventive Maintenance

Troubleshooting Without Prior Data BackupCommon mistake

When you use it

Consult this before performing any hardware diagnosis or maintenance procedure.

Watch out

Never start troubleshooting or hardware replacement before taking a complete backup of user data.

Fundamentals of Programming

Python Identifier Naming RulesRule

When you use it

Use when creating variable names and checking if an identifier is valid in Python.

Watch out

Variable names cannot start with a digit, cannot contain special characters like & or *, and cannot be Python keywords like while or if.

Syntax Errors versus Logic ErrorsRule

When you use it

Use to distinguish between program grammatical violations and incorrect computational results.

Watch out

Compilers and interpreters automatically detect syntax errors and stop execution, but logic errors do not generate error messages and must be found by checking program output.

Unconverted input() Return ValueCommon mistake

When you use it

Reach for this when reading numerical user input from the keyboard in Python.

Watch out

The input() function always returns a string (str), so performing arithmetic on it without explicit conversion using int() or float() causes a runtime TypeError.
