List two techniques of acquiring electronic images to be used in a desktop publishing program.

(ii) Describe two layout guides in a desktop publishing program (DTP) that assist a user to place an object in a preferred position.
(b) Explain three ways of ensuring that data submitted for processing is accurate.
(c)An engineering company requires a computer system to design roads and bridges.
Explain one suitable choice for:
(i) output device;
(ii) software.

RESPONSES

(a) (i) Ways of acquiring images in DTP:

Scanning;
Picture capture via camera;
downloading;
getting from secondary storage.

(ii) Layout guides

Ruler guides: a ruler on the edges of the page that guides a user to position objects and resize them;
Margin guides: used to define page margins so that the user will be prevented from placing objects in non-printable areas of the page;
Column guides: Vertical lines used to divide a page into two or more columns;
Row guides: Lines used to divide a publication page into two or more section to help structure the layout;
Snap points: Positions on the screen where the object is stuck on.

(b) Ways of ensuring accuracy of data during data processing

Data is stored in secondary storage in such a way that access to it is controlled.
Encrypting of data before it is transmitted to minimize chances of it being compromised during transmission.
Use of validation methods to ensure that data is correct at the point of input.
Use of direct data capture methods which eliminates human errors.
Use of verification methods.

(c) (i) Output device: A plotter because it prints large size drawings to high precision.
(ii) A CAD software because it facilitates in the design of engineering drawings.

(ii) Describe two layout guides in a desktop publishing program (DTP) that assist a user to place an object in a preferred position. (b) Explain three ways of ensuring that data submitted for processing is accurate. (c)An engineering company requires a computer system to design roads and bridges.
