Nobody can deny how amazing the Internet is! But it’s the result of a lot of developments and smart creations. So every time it improves somehow, the reason is, a technology or group of technologies behind it have really achieved the next level.
What is TCP/IP?
TCP/IP is a combination of two protocols, the Transmission Control Protocol and the Internet Protocol. It is a set of rules that are crucial for everyone involves to communicate within and across networks.

Time is a factor permanently present in our lives. It can be stressful, but it’s an efficient way to organize and control different aspects. The idea of chaos sometimes sounds exciting, but being realistic, it’s not viable when it’s about keeping a network running smoothly. That’s why TTL exists!
TTL, or time-to-live, is a mechanism to define the period of time for data to keep living, meaning being valid, stored, or to keep traveling on computers or networks. Once the TTL value defined by the administrators to those data expires, they get discarded.

Have you ever thought about the differences between FTP vs HTTP, and why do we use HTTP for the World Wide Web? Now you will have your answer.
What is FTP?
FTP stands for File Transfer Protocol, and it is a protocol that allows file transfer between two different hosts (devices) using the TCP/IP protocol. It is using the client-server model, where one of the hosts is called a remote host (server) and needs FTP software to be a server, and the other is called a local host (client) with FTP client’s software. Both of them need to be connected and configure to use the FTP protocol for communication.
FTP is used for:

IP address – What is it?
The IP (Internet Protocol) address helps with identifying most of the elements inside a network. Each device, laptop, computer, smartphone, etc., requires an IP address to successfully connect to a private network. Also, when we are talking about connecting to the Internet, we have the same case. The user is receiving a public IP address provided by an Internet service provider (ISP). For the purpose of operating accurately, servers also have a public IP address.
