Question 1 Report
(a) State the keyboard shortcut keys to;
(i) rotate an object in CorelDraw
(ii) position an object in CorelDraw
(iii) navigate to cell A1 in MS Excel worksheet
(b) Give one reason for including the plus sign (+) in the search text in a search engine.
(c) With the aid of diagrams, differentiate between LAN and WAN.
Answer Details
This question tests keyboard shortcuts, search-engine syntax, and the difference between LAN and WAN.
(a) Keyboard shortcuts.
- (i) Rotate an object in CorelDraw: click the object twice to get the rotation handles (Alt + F8 opens the Transformation/Rotate docker where the rotation angle is entered).
- (ii) Position an object in CorelDraw: Alt + F7 opens the Position (Transformation) docker used to move the object to an exact position.
- (iii) Navigate to cell A1 in an Excel worksheet: press Ctrl + Home.
(b) The plus sign (+) in search text. Placing a plus sign before a word tells the search engine that the word must be included in every result, narrowing the search to pages that contain that exact term.
(c) LAN versus WAN (with diagrams).
| Feature | LAN (Local Area Network) | WAN (Wide Area Network) |
|---|---|---|
| Coverage | Small area: one building or site | Very large area: cities, countries, worldwide |
| Ownership | Usually owned by one organisation | Often uses public/leased links, many owners |
| Speed | Higher data-transfer speed | Generally lower speed |
| Example | Office or school network | The Internet |
Simple sketches you should draw: a LAN as a few computers linked to one central switch/hub in a single room; a WAN as two or more such LANs in different towns joined by routers and a long-distance link (for example over the Internet).
Examination reminder: the single most important difference is geographical coverage - LAN is confined to one site, WAN spans large distances. The exam expects a labelled sketch, so always draw and label the nodes and the connecting link.
