Free short notes and revision cards
Grade 7 Information Technology on Temari has 16 revision cards, arranged by the chapters of the Ethiopian national curriculum. Every card says when the rule applies, what each symbol in it stands for, and the mistake students most often make with it. They are free to read and need no account.

When you use it
Use when identifying whether a given item is raw input or meaningful processed output.
Watch out
Never state that data has meaning on its own. Data consists of unorganized raw symbols or numbers, and it only becomes information after processing and interpretation.

When you use it
Use when comparing the scope and focus of Information Technology and Information Communication Technology.
Watch out
Do not treat IT and ICT as identical terms. IT focuses on managing data through computers, software, and hardware, whereas ICT emphasizes communication technologies and network integration.

| Element | Role in ICT System |
|---|---|
| Data | Raw representation of objects or events without context. |
| Information | Processed data that provides meaning and context. |
| User | Human who develops, maintains, and operates the ICT system. |
| Communication | Passing or transferring information from one place to another. |
| Technology | Set of tools and machines created by humans to solve problems. |
When you use it
Use when listing or explaining the foundational components that make up any ICT system.
Watch out
Do not omit User or Communication. An ICT system is not merely hardware and software, it requires human interaction and transmission.

| Function | Description |
|---|---|
| Input | Entering raw data into the computer system. |
| Processing | Manipulating data according to program instructions. |
| Storage | Saving data and information for later retrieval. |
| Output | Producing processed results as usable information. |
When you use it
Use when identifying the operational stages a computer performs on data.
Watch out
Do not confuse the sequence. Data must be entered before it can be processed, stored, or output.

| Unit | Equivalent Value |
|---|---|
| 1 Byte | 8 bits |
| 1 Kilobyte (KB) | 1,024 Bytes |
| 1 Megabyte (MB) | 1,024 Kilobytes |
| 1 Gigabyte (GB) | 1,024 Megabytes |
| 1 Terabyte (TB) | 1,024 Gigabytes |
When you use it
Use when converting between binary data measurement units from bits up to terabytes.
Watch out
1 Byte equals 8 bits, and each step from Kilobyte up uses a multiplier of 1,024, not 1,000.

When you use it
Use when answering conceptual questions about whether hardware or software can function alone.
Watch out
Hardware and software cannot work independently. Hardware cannot perform any task without software, and software cannot run without hardware.

| Screen Element | Function |
|---|---|
| Title bar | Displays program and document names at the top center |
| Menu bar | Contains major menu items such as Home, Insert, and Page Layout |

| Ribbon | Displays task buttons divided into tabs across the top |
| Status bar | Displays document information and insertion point location |
| Rulers | Show positions of margins, tabs, indents, and table columns |
When you use it
Use when identifying the components of the Microsoft Word user interface.

| System Software | Application Software |
|---|---|
| Designed for general purpose | Designed for a specific purpose |
| Runs from power-on until shutdown | Starts and stops when opened and closed by the user |
| Runs in background without direct user interaction | Users interact directly while performing tasks |
| Examples: Microsoft Windows | Examples: Microsoft Word |
When you use it
Use when differentiating between the two main categories of computer software.
Watch out
System software manages hardware resources in the background, while application software directly solves user tasks.
Drafted from Grade 7 Information Technology, pages 30-45, then checked twice before it went up
| Application Software | Main Purpose | Examples |
|---|---|---|
| Word processing | Creating, editing, formatting, and saving text documents | MS Word, WordPerfect, WordPad |
| Spreadsheet | Calculating and analyzing data in tabular form | MS Excel, FoxPro |
| Database management | Creating data tables, inserting records, and querying | MS Access |
| Graphics software | Creating and editing graphical images and designs | AutoCAD |
| Presentation software | Creating, editing, and formatting slide presentations | MS PowerPoint |
When you use it
Use when identifying common application programs and matching them to their specific tasks.
Watch out
FoxPro is listed in this curriculum as a spreadsheet example, not exclusively as a database.

| System Software Type | Function | Examples |
|---|---|---|
| Operating System | Manages hardware, loads programs, and controls files | Microsoft Windows |
| Utility Programs | System maintenance, configuration, and performance | Backup software, virus protection |
| Language Translator | Translates source code between programming languages | Compilers, translators |
When you use it
Use when identifying the three core types of system software and their duties.
Watch out
Utility software and language translators are types of system software, not application software.

When you use it
Use to break down and identify the structure of any URL or website address.
Watch out
In http://www.google.com, http:// is the protocol, www is the web indicator, google is the domain name, and .com is the domain extension.

When you use it
Use when identifying software used to access the internet versus online tools used to find information.
Watch out
Google Chrome is a web browser (an application installed on a computer), whereas Google (www.google.com) is a search engine (a web tool used to search information).

When you use it
Use before performing any physical maintenance or cleaning on computer hardware.
Watch out
Never spray liquid directly onto the monitor screen, and wait at least 30 minutes for monitors and laser printers to cool before cleaning.

When you use it
Use when creating a new password to prevent unauthorized access to a user account.
Watch out
A password must be at least 8 characters long and contain a mix of uppercase letters, lowercase letters, numbers, and symbols.

When you use it
Use when checking whether commands control distance or rotation.
Watch out
FORWARD and BACK take distance units, while RIGHT and LEFT take rotation angles in degrees. Writing rt 90 turns the turtle without moving it.

When you use it
Use when saving a sequence of drawing commands under a single reusable name.
Watch out
A procedure must start with TO and end with END. Calling a procedure name before defining it produces an error.

An exam paper keeps asking for what the year below taught. Those cards are here too.
Everything else in this year that has cards so far.
Temari turns these cards into practice questions and marks them as you go, with an AI tutor to explain anything that did not land.
