Introduction
As the use of computers is on the rise, the understanding of networks and how they interact with computers becomes a necessity for its end users. One of the pieces that allow the interaction of computers and networks is the protocol. According to Merriam-Webster dictionary, a protocol is essentially a set of rules that define how computers communicate with other computers over a network (Merriam-Webster). There are many protocols that presently exist (e.g. HyperText Transfer Protocol, Internet Protocol), but one of the most useful protocols to users who have the desire of sharing files with one another may just be the File Transfer Protocol, or FTP. This paper is designed to explain the history behind the FTP, its purpose, how it is used, and why it is useful to this group of users.
The History of FTP
FTP was first developed back in the early 1970s for indirectly accessing computers on a network (TCP/IP Guide). To access a computer over a network indirectly means to acquire files or data from a remotely hosted computer and placing them onto a local file system, or to place files from a locally hosted file system onto a remotely hosted computer. The initial version of FTP was first published in Request for Comments (RFC), a series of memos designed for explaining methods or research that applies to computer networking (Wikipedia). While this protocol has undergone a few revisions over the decades since its original development, its main purpose remains the same.
How FTP Works
There are four primary components in order to make FTP work: the FTP client, the FTP server, the control connection and a data connection between the two (DeskShare). This way, the operating systems and file system types do not need t...

An example of a highly important protocol which will be utilized at application level, is HTTP or hypertext transfer protocol. HTTP is the protocol used within web browsers and the entire internet to send and receive specific web page data. HTTP is a controlling protocol, as it determines how documents should be sent, and what the browser should do in response to commands. When accessing a web page, a HTTP command is sent to the pages web server, so that the server may send that specific page’s data to the user. PCO’s Learning Centre will be using the hypertext transfer protocol on a regular basis. In order for students to access web pages, the HTTP must exist to ensure speedy and accurate navigation, especially in a learning

Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world.
Spanning tree protocol is a protocol that prevents loops that are not wanted in a network. In order for a network to work properly it has to have only one active path between two network stations. If there are multiple active paths between stations loops can and will occur. When loops occur, there can sometimes be duplicate messages in the network. The loops are created by the network and if the devices that connect the network segments are all configured to forward, they will continuously forward frames into an endless network loop. If there are enough loops going then a frame will not reach its destination. The reason duplicate messages occur is because sometimes switches will see situations appear on both sides of it. When this occurs that is when spanning tree protocol comes in. In order to shut down the loops bridges and switches exchange BPDU messages with other bridges and switches to detect loops and then remove them by shutting down selected bridge interfaces. BPDU is short for bridge protocol data unit. Bridge protocol data units are part of the spanning tree protocol and they help describe and identify the parts of a switch port. The bridge protocol data unit allows switches to obtain information about each other. All the switches gather information from each other by exchanging data messages. In order for them to exchange messages they have to elect a root switch for the topology. The root switch has to be unique. The way they elect they have to have a unique switch for every local area network segment. To exchange messages they have to remove all loops by putting them in a backup state. Now to talk about states there is 5 different states. Two of the five states do not participate in frame forwarding. Frame forwarding is what the three main states do. The three main states are listening, learning, and forwarding. The other 2 are blocking state and disabled state. When you enable the spanning tree protocol the network goes through the blocking state and then the listening state and learning state are enabled after being turned on. If the protocol is properly configured the ports are stabilized to the forwarding or blocking state. The blocking state does not participate in the frame forwarding. It removes frames that are received from the attached segment. It also discards frames from another port for forwarding.
2. To transfer files from one computer to another (the files may be text, images, audio, video, etc.).
When electronic devices transfer information to another electronic device, the devices need to know when data flow is beginning and ending. This is done with signals for synchronization.i
...mputers and the internet were made to make things easier for people and the internet and World Wide Web were specifically made to file share. That was the whole purpose behind the net. That is why this file-sharing technology (P2P) is the new wave of the future and will be a large part of the internet for a long time to come.
In a client-server network, the capability of the server will decline as the amount of clients asking for services from the server increment. In spite of that, in P2P systems overall network performance really enhances as an increasing number of nodes are added to the system. These companions can arrange themselves into a specific purpose groups(ad hoc) as they impart, work together and offer data transfer capacity with another to finish the current workload (sharing of files). Each companion can transfer and download at the meantime, and in a procedure like this, new companions can join the group while old companions leave at whatever time. This active re-association of group peer members is not opaque to ultimate consumer.
People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
