Unit 30 M1

Task 1 M1
Limitations
Hardware
·         Computer – My computer I have chosen is a desktop computer, this means it has to be plugged in at all times and can’t be moved around, can be expensive, especially with custom components, computers can go out of date, this means I will have to purchase updates.
·         Keyboard – has to be plugged in, this means you are limited to space in which you can use the keyboard, can take up a fair bit of space
·         Mouse – has to be plugged in, limited to space and where you can use the mouse, can be hard to design with a mouse
·         Monitor – the monitor I have chosen costs a fair bit of money, but I have to have a good quality monitor for graphic designs.
Input devices
·         Digital Camera – the camera I have chosen is quite large, this means it’s not the most portable camera around, also it has a battery, and this means it only has a limited time and could die while I was using it.
·         Scanner – scanners are very slow, they are also quite big so they take up quite a bit of space
·         Graphics Tablet – these are very expensive and have to plugged in so you are limited to a space in which you can use it.
Output devices
·         Printer – you have to buy ink for printers, this ends up being very expensive and can end up costing more than the printer itself.
·         Vinyl Cutter – you have to purchase new cutter heads which are very expensive as they are diamonds, they can also be quite big and take up a lot of space.

Software
·         Photo Manipulation (Photoshop, Vector Software, Bitmap Software) – software can cost a lot especially with new updated versions being released; also some can be quite difficult to learn how to use, you’re limited to the program on how much you can do.
·         Drawing Packages - this is the same as the photo manipulation; they can also take a lot of time to learn even the basics.
·         Desktop Publishing - same limitations as the above two. But these are used in lots of areas so the limitations aren’t as strong as photo and drawing packages.
File Storage
·         External Hard Drive - they can break and you could lose a lot of work so they are unreliable.

Unit 30 P2

Bitmap
A bitmap is an image that is composed of a great amount of small squares, these small squares are called pixels, and you can get pixels in almost any colour thinkable. When you resize bitmap images it causes the image to loose quality, this is called ‘pixelated’ if you zoom in enough you will eventually start to see each individual pixel. Putting bitmap images on brochures and leaflets would be best, this is because they are very detailed, but when you put the image on the leaflet/ brochure, you should make sure the images are the original size or shrunk so they don’t pixelate and remain keeping their professional look. Examples of bitmap files are GIF, PNG, BMP and JPEG.
Vector
You create vector graphics in graphic packages, they are made up from shapes and objects, a benefit of making a vector graphic is that it’s a graphic and you are able to edit each object separately, you are able to change the colour, size, shape and position of each object. Another benefit is that you are able to make your graphic whatever size you want without it pixelating or losing any quality at all, and also these graphics take only a very small amount of computer memory. I think due to being able to make the graphic any size you want I think the vector graphic would be suitable for putting on vehicles as they would need a large image. Examples of vector graphics are AI, XAR FS and AWG.
PDF (Portable Document Format)
A PDF is a mixture of bitmap and vector images, but with these images, unlike printed documents, you can include links, audio, video, and images on your document, for this reason the PDF should be used on the website as it has many features in which you can use on the website.
