Packet 23 is a request from the client to start the data packet transfer from the server. The text STOR text.txt signifies this.
The computer requesting information is called a CLIENT. The computer responding to the request is called a SERVER. Data transfer from a client to as server is reffered to as an upload. EX. When you want to enter the game. Ur the client waiting for the server to get you in Data transfer from a server to a client is reffered to as a download. EX. When you download stuff from Limewire or Utorrent. Your the server waiting for the client to give you the song or movie.
The server knows by the destination port number, which attaches a listening program to a specific protocol.
In general, and in the simplest form, a server is a machine or a program (software application) that waits for incoming requests, and a client is a machine or program sending requests to another client or a server in order to take action
The File Transfer Protocol is a standard network protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client-server model architecture using separate control and data connections between the client and the server
If a client send a query requesting for a particular web page to the DNS server and if the DNS server resolves the page from the other DNS servers & it will be store the same page in the DNS cache and it will give the response to the client with the requested page. If again the same web page is requested by any client then DNS server will get the web page from the DNS cache instead of again fetching the same page from the internet. With this there wont be any delay for the client to get the web page. This helps in bandwidth control. This is how the DNS server caching works.
A File Transfer Protocol works on a client-server architecture and uses separate control and data connections between the server and the client. FTPs are used in businesses and government agencies world-wide.
Why would you want to do that? A file transfer usually takes place between two computers - one is operating as a client and the other as a server. Running the client and server portion on the same PC to transfer files is very inefficient. You can use the ftp client to communicate with the ftp service on the same server/pc the same way as you would across the network; there is no difference.
HTTP (web traffic) may be used in either peer to peer networks or client server networks. Either way, it is the same protocol. It is used to transmit a browser request to a web server or to transfer a page from a web server to a client browser.
A client is the requesting program or user in a client/server relationship. For example, the user of a Web browser is effectively making client requests for pages from servers all over the Web. The browser itself is a client in its relationship with the computer that is getting and returning the requested HTML file. The computer handling the request and sending back the HTML file is a server.
File Transfer Protocol (FTP) is used for transferring files between an FTP client and an FTP server.

Pretty much a client server network is known as a client server network.
