What does FTP mean?

FTP – what does it mean?

FTP, or File Transfer Protocol, is a standard communications protocol for transferring data between devices across a network. A TCP/IP (Internet) connection is also available between the two. FTP is a network protocol that connects a user to a server and allows users to download files, pages, or applications that are available on other services. File Transfer Protocol is usually using by the user when they need to download data to their personal device.

It’s worth noting that File Transfer Protocol does not use encryption. Instead, it exclusively uses cleartext users and passwords for authentication purposes. Unfortunately, this leaves information delivered via FTP vulnerable to simple impersonation and other forms of attacks. There is, however, SFTP (Secure File Transfer Protocol), which can allow secure file transfer.

Benefits of using it

FTP is absolutely advantageous. Here are some of its benefits:

  • You can use File Transfer Protocol to transport huge files.
  • Also, you can submit multiple folders containing files simultaneously to expedite the transfer process.
  • You can re-establish an interrupted File Transfer Protocol connection.
  • And in addition, the transfers of schedules are possible.

FTP applications

  1. You can collect data from linked devices — The number of IoT devices is growing, and all of them, including laptops, PCs, and tablets, are connected to the Internet. Without the need for human interaction, you may obtain all of the data and transfer it via a wireless network. The data transfers on a regular basis when automated FTP transfers are set up.
  2. Business of e-commerce – Online shopping is convenient and offers numerous advantages. However, a lot is going on behind the scenes. Secure File Transfer Protocol (SFTP) aids e-commerce businesses by transmitting data to various critical business systems, such as analytics. The company will be able to continue moving forward in this manner.
  3. A content distribution network (CDN) – is a system that allows you to share your content with others. Large media content organizations, as well as various radio and television shows, require reliable data delivery. This ensures that presentations are broadcast on time. FTP’s ability to transport large amounts of data is advantageous to them.

FTP vs HTTP

HTTP stands for Hypertext Transfer Protocol, and it is a protocol for loading documents via hyperlinks on the Internet (World Wide Web). It also follows the same client-server concept as FTP, in which a client sends a request, and the server responds with the content or action requested. The most common HTTP requests are GET (for getting a specific resource) and POST (for posting text or a file).

Let’s look at the differences and similarities between FTP and HTTP. You might be quite surprising at how much the two network protocols have in common.

  • FTP and HTTP are both types of network protocols.
  • FTPS and HTTPS are secure versions of FTP and HTTP that use data encryption.
  • Both FTP and HTTP are still in use on the Internet and can be used to transmit files.
  • The TCP protocol is used by both FTP and HTTP but on different ports.
  • After establishing a connection, the purpose of File Transfer Protocol is to transmit files from a remote host, while HTTP is used to browse the web after establishing a connection.
  • Because HTTP can download a file in pieces and speed up the transfer, FTP usually is slower than HTTP. In addition, if there are several files, the FTP must re-establish the connection between each one, which takes time.

Conclusion

You now understand what FTP is and what it does. It is a well-known file-exchange protocol. Of course, it isn’t perfect, but there are ways to improve its security and use it.

What is TCP/IP and how does it work?

TCP/IP is a set of communications protocols that is still relatively unknown. It is a combination of two different components – TCP and IP. This article will look at what it is and how it works.

The definition of TCP/IP

TCP/IP is an abbreviation for Transmission Control Protocol/Internet Protocol. The two protocols (TCP and IP), each with its own set of restrictions, are integrate initially and used for machine communication on networks, including the Internet. It defines how the data travels by determining how it should be split into distinct packets for address, routing, transportation, and delivery.

  • IP – The Internet protocol (IP) specifies the formats and rules that devices and applications should follow when communicating and exchanging data packets within or across networks. IP is responsible for addressing and routing data packets sent from a source to a destination point.
  • TCP – The transmission control protocol (TCP) arranges data during communication between a client and a server in such a way that it is secure. TCP is in responsible of assuring data integrity from the time it leaves the sender’s computer until it arrives at its final destination.

How does it work?

TCP is a protocol that manages connections. Therefore, an active link between the source and the recipient is essential for completing the procedure from start to finish.

TCP chops the message that originated on the source into packets after meeting this requirement. TCP then assigns a number to each of those packets to maintain the message’s integrity. The network layer (the IP) is now ready to receive packets . They will pass via various gateways, routers, and even pathways on their journey to their destination. Exactly! All packets belonging to the same message might be routed differently because they are split. But, finally, they should meet at the exact location. TCP then rebuilds the message to deliver it, following the numerical order of all packets. And it is at this point that the procedure is accomplished.

The TCP/IP model’s four elements

We separate TCP/IP into four elements, also known as layers, and each one has its programming interface. We are going to take a brief look at them, as follow:

  • Internet layer – The internet layer, also known as the network layer, is in charge of packet flow throughout the network. We mainly use it to report errors.
  • Physical layer – The network interface layer is another name for it. This element is in charge of the physical aspects of delivering and receiving data via wireless networks, Ethernet cables, computer device drivers, etc.
  • Application layer – The application layer is a collection of apps that need to communicate through a network. This is where the user interacts most frequently, including through email and messaging.
  • The transport layer establishes a secure data connection between two devices. It ensures that the other device acknowledges the packets it receives.

Conclusion

The Domain Name System operates in the background, and the Internet would not exist without the contributions of every component of its complex system. TCP/IP is a critical component of that machine. Its features have ensured that it remains an essential technology for managing large and complicated networks like the Internet.
