A graphics tablet is also known as a drawing tablet or a digitalizer. It is an input device and allows users such as graphic designers to draw an image freehandedly and convert it into a digital image. The mouse is a very inaccurate device when drawing an image free handed on screen. The graphics tablet however is a lot more accurate when drawing images on screen and you can even trace over photos on paper to make the image on screen look more realistic and artistic.This will help Adam to illustrate graphics for his work.This is the easiest way to draw and he will not face any trouble with the drawing tools.He also will not waste paper just for drawing.

MONITOR

Adam will need a monitor because it is also an important piece of hardware that is used in a computer system to create and manipulate digital graphics. The monitor is important as it outputs the software interface onto the screen allowing the user to view the image that they are creating and it allows them to edit the image as they can interact with the software. Dual monitors are very useful in the digital graphics field as the desktop can display more surface area allowing them to have multiple images or programs open on screen at a time.

A printer is an output device that converts an electronic document onto printing paper, photo paper, transparent film, etc. The main modern types of printers are toner based printers, liquid ink jet printers, solid ink printers, inkless printers and dye sublimination printers. Once Adam has finished editing his image, he can print it out onto high resolution paper. This means that he can transfer the digital image to a photographic output. Most graphic designers use high quality printers. The higher the quality of printer that they use means the better quality the image will look.

A digital scanner is a device that will optically scan text, handwriting or an object and convert it into a digital image. A modern scanner will typically use a charged coupled device which is also known as a CDD. Older drum scanners use a photomultiplier tube as an image sensor. A scanner is a useful piece of hardware in relation to creating and manipulating digital graphics because it allows the graphic designer to copy images of paper and convert it into a digital image that the graphic designer can then edit. Digital scanners can scan in different modes such as different colour schemes. The resolution of the scanner can impact how the image appears on screen. The higher the resolution the better the quality the image will appear on screen.Scanner will help Adam to create a better look commercial product such as greeting cards and magazines.
