vector

hardware
hardware is the general bits that make up a computer including the monitor and the mouse also the keyboard.
software
there are two types of software and they are systems software and applications software.
input
an input device is a piece of hardware that is used to enter data in a computer.
output
an output device is a piece of hardware that obey a computer command.
task 1
some vector input are a tablet and a mouse. also some outputs are printers and virtual ink.
bitmap input and output
the input is what you put in and the output is what you get out.
task 2
an vector image is made up of paths and curves and pixels.
task 3
they used AI CDR and cgm swf dxf to create vector images.
digital camera
Digital cameras work in an completely different way. When you press the button to take a picture with a digital camera an aperture opens at the front of the camera and light streams through the lens. From this point on however everything is different. there is no film in a digital camera . Instead there is a piece of electronic equipment that captures the incoming light rays and turns them into electricals signals. This light detector is called a charge-coupled device(ccd).
        

1. Battery compartment: This camera takes two 1.5-volt batteries, so it runs on a total voltage of 3 volts (3 V).
2. Flash capacitor: The capacitor charges up for several seconds to store enough energy to fire the flash.
3. Flash lamp: Operated by the capacitor. It takes a fair bit of energy to fire a xenon flash like this, which is why a lot of indoor flash photography quickly uses up your batteries.
4. LED: A small red LED (light-emitting diode) indicates when the self-timer is operating, so you can take photos of yourself more easily.
5. Lens: The lens catches light from the object you're photographing and focuses it on the CCD.
6. Focusing mechanism: This camera has a simple switch-operated focus that toggles the lens between two positions for taking either close-ups or distant shots.
7. CCD: This is the light-detecting microchip in a digital camera. You can't actually see the CCD in this photo, because it's directly underneath the lens. But you can see what it looks like in our article on webcams.
8. USB connector: Attach a USB cable here and connect it to your computer to download the photos you've taken. To your computer, your camera looks like just another memory device (like a hard drive or aflash memory).
9. SD (secure digital) card slot: You can slide a flash memory card in here for storing more photos. The camera has a very small internal memory that will store photos too.
10. Processor chip: The camera's main digital "brain". This controls all the camera's functions. It's an example of an integrated circuit.
11. Wrist connector: The strap that keeps the camera securely tied to your wrist attaches here.
12. Top case: Simply screws on top of the bottom case shown here.

scanners  

Scanners have become a very important part of the home office over the last few years. Scanner technology is everywhere and used in many ways;

Flatbed scanners, also called desktop scanners are the most versatile and commonly used scanners . 

parts of a Flatbed scanner.
The use of vector images is the use of geometrical primitives such as lines points curves and shapes such as polygons which are all based on mathematical equations to represent images in computer graphics.
Vector graphics formats are complementary to raster graphics which is the representation of images as a array of pixels,as is typically used for the representation of photographic images. there are instances when working with vector tools and formats is the best practice,and instances when working with raster tools and formats is the best practice. There are times when both formats come together. An understanding of the advantages and limitations of each technology and the relationship between them is most likely to result in effective use of tools. computer displays are made up of grids of small rectangular cells called pixels.
