(a) Figure 1 illustrates a part of a computer system.
Figure 1: front view of an optical disk (CD/DVD) drive - Y is the disk drive, X the on/off (open-close) button and Z the compact disk on the tray.
Figure 1
(i) Identify the part labelled Y.
(ii) State:
I. The technology used in the part labelled Z.
II. The function of the part labelled X.
III. One maintenance practice for the part labelled Z.
(b) Figure 2 shows a set-up of a computer system. State one function of each of the parts labelled P, Q, R, S and T.
Figure 2: a desktop computer system set-up - P monitor, Q system unit, R mouse, S keyboard and T flash drive.
Figure 2
(c) Outline the steps taken to perform the following tasks in the CorelDraw application:
(i) Insert a circular shape.
(ii) Add the caption "Happy Birthday" around the circular shape.
(iii) Change the colour of the caption to green.
This practical question tests recognition of computer-system parts from two figures and CorelDraw operations. The parts labelled X, Y, Z (Fig 1) and P, Q, R, S, T (Fig 2) depend on the figures in your paper, so name them against the labels shown; the CorelDraw steps below are complete.
(a) Fig 1. Identify the labelled part Y and describe the technology and function of the other labels from the diagram (a common set-up shows a monitor, whose display technology is LCD/LED, and a system unit). Typical answers: the technology of a flat-screen monitor is LCD/LED; a maintenance practice for a screen is to clean it gently with a soft, dry (or slightly damp) lint-free cloth and keep it dust-free. Match each label to the exact part your figure points to.
(b) Fig 2 (functions of labelled parts). For each of P, Q, R, S and T, state the function of whatever component the label points to. Common components and their functions: monitor - displays output; keyboard - enters text/commands; mouse - points and selects; system unit - houses the processor and does the processing; printer - produces hard-copy output. Assign these to the labels as shown in your figure.
(c) CorelDraw tasks.
(i) Insert a circular shape: select the Ellipse tool from the toolbox, hold down the Ctrl key and drag on the page to draw a perfect circle.
(ii) Add the caption "Happy Birthday" around the circle: select the Text tool, click on the edge/path of the circle so the text snaps to it (fit text to path), then type Happy Birthday so the words follow the curve.
(iii) Change the caption colour to green: select the text, then left-click the green swatch on the colour palette (or open the fill colour and choose green).
Examination reminder: in CorelDraw, holding Ctrl while dragging the Ellipse tool constrains it to a perfect circle, and clicking the Text tool on a shape's outline lets text follow the path.
