What are bitmap made from and why are they suitable?

# data[].attributes.body
a bitmap is composed into many tiny parts which are called pixels. these are often used in different colors. you can edit each individual pixel. when you take a photo using digital camera you are creating a bitmap. it is suitable when editing photos to make them look amazing however look real at the same time.

Bitmap Enlargement and reduction quality

# data[].attributes.body
When resizing a Bitmap into a larger scale the quality of the picture gets worse. when using bitmap the image will look fine when zoom out but when zooming in the quality becomes worse however to stop this the file of the bitmap image will be larger which is why people change the size in the first place.

What are vectors made from and what are they suitable for?

# data[].attributes.body
Vectors graphics are compromised routes which are defined by start and end point with points, curves and angles along the way. it can be a line, square, triangle or a curved shape. they can be use to create simple drawings or complex diagrams. each of the different points are located on the x and y axis.

Vector File Size/Can Vectors be grouped?

# data[].attributes.body
Vector Images can indeed be grouped. These Grouped vector images are beneficial to users as they can be moved around whilst maintained in the same proportion as it was originally. Grouped Vectors graphics can actually be manipulated further than what they already were due to them being in one group and not a variety of separate objects. Vector file sizes are usually smaller than bitmap graphics due to them only holding equations. however, this does depend on what file you are storing.

Bitmap File size/Can Bitmap Graphics be grouped?

# data[].attributes.body
A Bitmap file size tends to be larger than a Vector's file size as a computer stores all information of the pixels used where as Vector graphic only deals with formulas and equations. Bitmap Graphics can not be grouped as Grouping functions on software's do not support this particular graphics type. if Pixels on a bitmap graphic are set a 8 bits, this implies that this graphic file size would be 8 times bigger than what it would be in black and white.

File compression is a method of data compression in which a size of a file is decrease to save space on a disk for faster transmission over the network or the internet. it allows the creation of a version of 1 or more files with the same data at a smaller size than the original.
file compression is allowed through files or a data compression software which creates a compressed version of each file. it works by scanning an whole file and identifying similar data and replacing the duplicates with a unique identifier.

We need compression so our files can stay in their own format

Lossless compression is used to reduce a file size without the loss of any quality on both images and audio files. JPEGs and MP3s use lossy compression which means that some of the quality from the image is lost but newer compression algorithms such as Apple Lossless and JPEG 2000 can be used to compress files with no loss of quality. Lossless compression rewrites the data inside the original file in a more efficient way but because no quality is lost the files are typically larger than a file compressed using lossy compression. With lossless compression you will be unlikely to produce a file smaller than half the original size but with lossy you could get it to be one tenth the size but quality will be lost on the image.

Lossy compression is where you compress a file and the quality and amount of data is lost when doing so. Lossy Compression is typically used when making a pictures in to a JPEG. As you are compressing a file when opening the image as its new and compressed image, the picture quality will be very noticeable. However when using Lossy the file size will be significantly smaller than lossless. This is ideal for sending the image by emails or simply making more room and saving time. When using lossy rather than lossy less there are many more tools and plugins compatible with lossy pictures.
