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).

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.
