The data package containing the header and the data from the upper layer then becomes the data that is repackaged at the next lower level with lower layer's header. Mcq Added by: Muhammad Bilal Khattak. When data moves from upper layer to lower layer of TCP/IP protocol stack, during an outgoing transmission, each layer includes a bundle of relevant information called "header" along with the actual data. A. Consequently, just defining data manipulation as CRUD isn’t enough, but when approaching functional programming it’s a start. Object B. Merging and matching The data for an analysis often do not come in a single file. The reverse of data encapsulation is decapsulation, which refers to the successive layers of data being removed (essentially unwrapped) at the receiving end of a network.
