Hardware components to create and manipulate Digital Graphics

There are various hardware components that can be used to create and manipulate digital graphics.  I will now describe these components:

Mouse


DefinitionA mouse is a component that is connected to the computer through a USB.  The mouse is used as a pointing device on the computer and functions by a person’s hand.
How a mouse is used to manipulate a digital graphic The mouse can change any aspect of any image simply by the user clicking on either the right or left button and clicking on a colour or an icon in which to change an image’s size or shape etc.


Screen/Monitor

Definition A screen/monitor is another external component of the computer and is used as a visual device which means it is used to see the things that are being done on a computer.
How you use a computer monitor to manipulate a digital graphic With the computer monitor you are able to see what changes are being made to the image, and also how to make those changes.
Without the computer monitor you are unable to see if the changes that are being made are the right changes or not.



Graphics Tablet

DefinitionA graphics tablet is a device that is used as a drawing device for the computer.  This means people can draw on the tablet and it will appear on the computer in front of you. With this device they are able to change any aspect of an image and they can also sign their signature at the bottom.
How a graphics tablet is used to manipulate a digital graphic A graphics tablet can be used to change different aspects of any image on a computer, it can also be used to erase even the tiniest piece of mistake made on an image.  Graphic Tablets are also used to change colour and re paint a picture and make many other changes.




Digital Camera


Definition A digital camera is a hand held device, it is used to take pictures of almost anything and is also built in a way that it can record videos of everything around you.  Digital cameras also have automatic flash built in so that it can make a picture clearer.
How you use a digital camera to manipulate a digital graphic A digital camera is plugged into the computer using a USB adapter and from there any pictures that have been taken using the camera and are saved on the device can be uploaded to the computer and saved in a folder and from there you are able to make changes to any pictures e.g. Changing the colour, shape and fixing red eye etc. 




Scanner


Definition A scanner or an image scanner is a component that is plugged into the computer through an adapter.  It is used to scan hard back photographs and upload them to the computer which turns them into a digital image.
How an image scanner is used to manipulate a digital graphic An image scanner is used to upload images to the computer and from there you can make any changes to them.



Flash Card

Definition A flash card is a miniature storage device that uses a flash memory chip to store data.  Flash cards come in all sizes and the memory can range from 8mb to a high capacity of gigabytes.
How a flash card is used to manipulate a digital graphic – A flash card is used as extra memory or storage in a computer or a digital object i.e. Digital camera’s.


USB Storage

Definition - USB storage device is a device that is used to store data of all types from a computer.
How USB storage device is used to manipulate a digital graphic - USB devices are plugged into the computer and files are stored onto it and then it is removed from the computer.   A USB device is also used to transfer videos, pictures and files etc from one computer to the other.


Firewire


Definition   

 Firewire is a high-speed interface for connecting peripherals.  Firewire was originally   created by Apple computer in the mid 1990's.  Firewire is a cable that can be used to connect various devices such as Digital camera's, MP3 players, Hard Drives, Audio interfaces and also the Apple Ipod to a standard computer.
How Firewire is used to manipulate a digital graphic

 Firewire is a high-speed cable which is used to connect various devices to the computer, this includes the standard digital camera or video camera.  The cable is used to transfer the images from the digital camera to the computer in high-speed.

  2. I am impressed on how you described the uses of the hardware components. But, I think it is better if you include all the specification of the hardware components.
