The HTTP protocol is primarily used to transfer information between remote systems. Data needs to be serialized into bytes to be able to be transferred from one point to another; however, manipulating bytes in your application is probably challenging and error-prone. The regular approach to this problem is to create classes in your code that represent the data you are sending or receiving.
