2. Graphics card A graphics card is a piece of software that takes binary data from the CPU and converts it into a wire frame out of straight lines. Then the image is rasterized so the remaining pixels are filled in and then lighting texture and colour. In fast paced adverts or games the graphics card will need to do this around 60 times per second (60fps). They produce all the text and images you can see displayed on a computer. it can either be inserted into a computer or it is already built-in. The 4 components are: a mother board for connection, a processor to decide what to do with the pixels, memory to hold information about the pixels and a connection

3. Graphics tablet A graphics tablet is used for drawing on a computer without using a mouse or keyboard and are usually used with a board and a stylus. It works by the tablet sensing where the stylus has touched it, it then plots the information of the position of where the pen has touched onto the canvas on the computer. It is useful because people can draw normally like with a pen so drawing can look better and the graphics in games or adverts will look more realistic. As they can be rendered and edited more easily as it is already a digital file instead of a less accurate, responsive mouse to paint the picture

4. Digital camera A digital camera is an electric camera which can take pictures or videos and the pictures can be uploaded onto the computer which then can be shared with others or made into a movie which can be edited which is why they are useful. I t works by sensing the light in the picture when it is taken and then it is converted into electrical charges. The charges then can be read and then used to code the combination of colour on the pixels to reform the image either on the camera or on your monitor

5. Printer Printers are used for printing out a picture from the computer. They can be used to either print out pictures uploaded from a camera or directly from the internet. Some printers are also scanners so you can also copy a picture directly from a picture or document you have made. They work by using the code given by the document you are printing to create a direct copy of it using the cartridge to make each tiny little dot that all comes together to form the image on paper.

6. Monitor Monitors display everything on the computer so you can see your work. either you buy these with a computer or you can buy them together in a laptop. These prices can vary from a few pounds to a few hundred pounds. They work by taking the information given by the source such as the pc or games console and converting the information into the code for colouring each individual pixel to form the image on the monitor.

7. CD ROM A CD ROM is a disk with readable information on it and when put in a CD ROM player or HDD you can see the information. Many things can be stored on CD ROM’s from pictures to presentations to games. It works by converting all the information put on it into miniature bumps which like binary can be read and interpreted by a HDD

8. HDD HDD or hard disk drive is the player of CD ROM’s which has the ability to read and access stored information or games On these CD ROMs. It does this by using a laser to scan the bumps in the cd and then converts it into information to show on the device.

9. Memory SD card Memory SD cards care other ways to store information. Usually in cameras and phones there is only a small limited amount of space so the memory cards massively increase the amount of pictures or movies or games stored. Memory cards can store at least 2 megabytes worth of stuff on it so it is very useful for storing information. It works by storing the data onto a series of electronic components called NAND chips which can quickly transfer information onto the receptor.

10. Different graphics software Vector graphics software Vector graphics is software using many different shapes such as points, lines, curves and polygons combined into one image instead of bitmap using dots.. These are very smooth and can easily be resized unlike bitmap. some programs that use vector graphics are: Corel Draw Visio

11. Bitmap software The second software package is bitmap or raster software which is another graphics software where the image consists of pixels, each one containing information about the colour. Each bitmap image has a fixed resolution so it cannot be resized without losing picture quality. Also when put in front of a coloured screen bitmaps have a white rectangle background because of the pixels Some bitmap programs are: paint shop pro, paint

12. Photo manipulation software Photo manipulation software is for adding something else to the image and editing the image to make a sort of illusion. This would be useful because bitmap images white screen background can get in the way of things and if the image is bitmap you can easily get rid of them. An example of photo manipulation software is: Photoshop

13. Photoshop vs paint Photoshop uses photo manipulation software to create, edit and mix photos together to make new ones. Good points: 1.Uses many useful applications to edit the images 2.Uses a wide range of tools for the process 3.When editing pictures it stays at good quality of resolution Bad points: 1.Can be quite complicated to use 2.Images can pixelate and lose picture quality when resized 3. Is expensive unless you are a professional it isn't really worth it

14. Paint Paint is a fun easy way to create simple images good points 1. Is free on a windows computer 2. Extremely easy to use 3. Something fun to do when there is nothing else to do Bad points 1.Doesn’t give good enough quality for something professional 2.Also loses picture quality when resized 3.Very limited amount of tools

15. The best program for creating and editing Out of all the programs the best one in my opinion is Photoshop because it is fairly easy to use for experienced computer users, fairly good at creating and great at editing. Paint may be easier to use but that’s because there is a limited range of tools to use meaning there is only a certain amount of quality you can expect whilst there is a wide range of tools for creating and editing to use so that is why Photoshop is the best.

16. Converting files The need for converting files is that: some web pages need a specific type of file (e.g. jpeg) to work, some images work better like jpeg doesn’t have a white background whilst png does or some different types of images take up less room so more space is saved if there is a limit to the amount.

17. The different file types BMP- uses bitmapped graphics for images which is used in the windows environment. PNG- stands for portable network graphics and is similar to GIF except it is patent and license free but it cant support animations unlike GIF. GIF- stands for graphics interchange format unlike jpeg can only contain 256 colours but are still useful for basic line drawings etc. JPEG- stands for joint photographic experts group and unlike GIF can contain 16 million colours so it is better for graphic and detailed images even though it is not very good for line drawings.

18. Compression techniques The objective of image compression is to reduce irrelevance and redundancy of the image. This is done through Lossy or Lossless compression. Lossless is done by representing data more effectively without losing information. This is appropriate for man made pictures like drawings or cartoons. Lossy is the technique of actually removing information that isn’t needed therefore reducing the space took up by the useful information. This is used for natural images such as photographs. This also helps reduce file size so you could make the image larger or higher quality.

19. Image resolution Image resolution is the amount of detail an image holds meaning higher resolution is higher detail in the image. Although it takes up more file size, it has a large effect on the quality of the image.

20. Colour depth Colour depth or bit depth is the amount of bits used to indicate the colour of a pixel in bitmap graphics which is represented as bits per pixel (bpp). A high bpp helps express colours more finely helping to the overall quality of the image.
