Fascinating Fact:

Compression reduces file size, which helps with storage and uploading, but heavy compression can lower quality.

In KS3 ICT, processing text and images is about making information clear and fit for purpose. This includes choosing suitable file types, arranging content for readability, and preparing images so they look right on screen and in print.

Key Terms

Compression: Reducing a file’s size so it takes up less storage and is quicker to send.
File format: The type of file, such as JPG, PNG, or DOCX, which affects how it stores data.
Readability: How easy text is to read, influenced by layout, font choice, and spacing.

Frequently Asked Questions (Click to see answers)

What does file compression mean in ICT?

File compression means shrinking a file so it uses less storage. It works by removing some data or storing it more efficiently, which makes sharing faster.

Does compressing an image always reduce quality?

Not always. Some compression is designed to keep the image looking the same to the human eye, but heavy compression can remove detail and cause blurring or blocky shapes.

Why do different image file types exist like JPG and PNG?

Different file types store images in different ways. JPG is often used for photos because it creates smaller files, while PNG is useful for sharp graphics and images that need transparent backgrounds.

JPEG is the same as JPG and it stands for the organisation that devised this file type, the Joint Photographic Experts Group. It is a much more efficient method of storing photographic images than other file formats

3.

[ ]	cartoon drawings
[ ]	electronic illustrations which are copyright free

Clip-art is often charged for and covered by copyright so you should really check with the owner before using clip art for your own work

[ ]	are always copyright free
[ ]	are free to use so long as you acknowledge the source
[x]	are sometimes protected and require permission to use

Using copyright protected images without permission is theft! When selecting digital images to use, look for ones that are in the public domain. This means that the owner is quite happy for anyone to use their image without having to pay for it or steal it

There are filters to improve an image, like make it sharper or change its colour, brightness, contrast etc. There are all sorts of unusual and creative effects too, but use them carefully or you could end up with an image that only you like!
