Study Notes
Internet Protocols
The Internet Protocols, collectively known as TCP/IP, are a set of communication protocols that enable the global Internet. These protocols provide the foundation for the transfer of data between devices and enable the establishment of connections between networks. The two most important protocols in this suite are Transmission Control Protocol (TCP) and Internet Protocol (IP).
File Transfer Protocol (FTP)
File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network. FTP is built on top of TCP, which is responsible for ensuring the reliability of data transmission. The protocol allows for the transfer of files in different formats, including text, image, audio, and video files.
FTP provides two modes of operation: Active and Passive. In the Active mode, the client initiates the data connection to the server. In contrast, in the Passive mode, the server initiates the data connection to the client. This flexibility allows FTP to function in various network environments, including behind firewalls.
TCP/IP
TCP/IP is a set of protocols that forms the basis of the Internet. The protocol suite consists of several layers, each responsible for different aspects of the communication process. At the highest level is the Application layer, which includes protocols like HTTP, FTP, and SMTP. Below the Application layer is the Transport layer, where TCP resides. TCP is responsible for establishing, maintaining, and terminating connections between devices, ensuring that data is delivered reliably and in the correct order.
The IP layer, located below the Transport layer, is responsible for addressing and routing data packets across the Internet. IP provides the necessary mechanisms to ensure that data is delivered to the correct destination on the network, even if the network topology changes. IP also ensures that data is delivered efficiently by breaking it into small packets and sending them over the network.
In summary, TCP/IP is a powerful set of protocols that enable the Internet to function as a global communication network. These protocols provide the standards and mechanisms necessary for devices to communicate with each other, ensuring the reliable transfer of data across vast distances.
Test your knowledge of the Internet Protocols, including TCP/IP, FTP, and how they enable data transfer and communication between devices on the internet.
