Encoder is important because Encoding keeps your data safe since the files are not readable unless you have access to the algorithms that were used to encode it. This is a good way to protect your data from theft since any stolen files would not be usable.Encoding is an ideal solution if you need to have third parties access your archives but do not want to have everyone be able to access some sensitive files.Since encoder removes redundancies from data, the size of your files will be a lot smaller. This results in faster input speed when data is saved.
