Introduction

Unit 3 Assignment 5 Computer Hardware Christopher Perkins User needs The users are anyone interested in purchasing computer hardware. The users need a series of web pages to allow them to explore further which computer hardware they may want to buy. These pages need to be set in out in simple easy to understand language so as not to confuse a new user with too much technical information. My plan I will create seven pages using text and graphics. I will use hypertext links and image hyperlinks to link the pages. My six pages will be: * Main Menu - this will contain the contents of the other pages and links to them. * Input Devices * Output Devices * Storage Devices * Main Processing Unit * Health & Safety - This will contain information on how to use your computer safely. Each Device page will have details of: * The item * The description * An image * An estimated cost Each page will link back to the main menu so that the user can then select the next page to view. I will use the Internet and catalogues to research current prices and find images of each device on my web pages. I will save the images into a folder called "Hardware Pictures" to store the different pictures I need. To save the pictures I will have to right click on the image I want and select save picture as, and name it with a sensible reference, before saving it to my folder. I will use the program Front Page Express to create my pages in HTML format; this is HyperText Markup Language and is the code used for producing Web pages. I will be able to design each page visually, by inputting text, background colours, images and links and then save the file in HTML format. I will use the Internet Explorer as my browser to view them as web pages. ...read more.
