Because the server at the destination would send a message back to the computer that sent it, like a receipt.
In computer science, a port is a number - commonly used in the TCP and UDP protocols - used to distinguish different applications on a computer. Ports are also used to distinguish different data flows on one computer. For example, if I connect to a Web server, the destination port will be port #80 - that way, the destination computer knows that the data should go to the Web server, and not to some other application. And the origin port might be, for example, port #1024 for one file I get from the server, and port #1025 for another file I get from the same server.In computer science, a port is a number - commonly used in the TCP and UDP protocols - used to distinguish different applications on a computer.

Internal data bus is defined as a collection or a sequence of the signal line that are responsible for carrying data from one computer to another computer or from one destination to another destination. Basically it is used to transfer data to the external drives and also referred as the internal bus.
In computer networking, a packet is a segment of data that is sent over a network from one device, including a computer, to another device. It contains the size, data, type, source. and destination that helps it get to the right destination.
Many computer commands move data from one file to another or from one storage device to another. This is referred to as moving the data from the source to the destination (or target). The term is also used as an adjective, as in destination file or destination device.So basically where every your moving your file or etc... too is the destination device.

By using CRC cyclic Redundancy check.
A proxy is a middle-man that receives data from your computer and then sends it to the destination, so that way your IP address is never exposed.
Process by which a message is sent from a single host to all hosts on the network, without regard to the kind of data being sent or the destination of the data.
The message must travel from your computer to your router. Every computer connected to a network has a network interface card (NIC) with a unique physical address, called a MAC address (for Media Access Control). At the data link level, two more headers are added, one for your computer's NIC address (the source MAC) and one for your router's NIC address. A data link layer structure with destination MAC, source MAC, and data is called a frame. Every NIC selects from the network those frames with its own address as a destination address. The data link layer adds the structure necessary for data to get from your computer to another computer (a router is just a dedicated computer) on your network. Data Link Layer Transformation.

Data Terminal Equipment (DTE)A Data Terminal Equipment (DTE) is a communication device that is the source or destination of signals on a network, typically a terminal or a computer. It communicaties with the data circuit-terminating equipment and can perform all the required functions necessary to permit users to communicate.
