Hi,
Byte represents an 8-bit unsigned integer. The byte array provides a mechanism to create an array of bytes. Each element within byte array is a byte or an integer between 0-255.
Files are made of bytes. A byte array represents the data within the an binary file. That means we can manipulate(write/read) any kind of binary file. For example, To save an image into database you firstly need to read this image into byte array and
then you can save it into database. Instead, if you want to display the image from database in the page, you also need to use byte array to retrieve the image and then output it.
