TCP/IP (Transfer Control Protocol/Internet Protocol), is responsible for complete data connectivity and transmission of data from one user to another. other. TCP manages the part of the message that is broken into packets and then transmitted over the network. The packets are then received by an equivalent TCP protocol upon receipt and reassembled into the original message. The IP address mainly affects the transmission part. IP addresses are assigned to each other and to any user/recipient active on the network. However, TCP/IP is divided into four layers, namely the network interaction layer, the Internet layer, the transport layer and the application layer, and they are all responsible for managing different sections of the transmission process .

FTP uses TCP/IP Internet protocols to enable data transfer. FTP is commonly used to download a file from a server using the Internet or to upload a file to the server. HTTP - HyperText Transfer Protocol allows users of the World Wide Web to exchange information found on web pages. This protocol specifies how messages are formatted and transmitted and what actions web servers and browsers should perform in response to various commands. For example, when the user enters a URL into their browser, it sends an HTTP command to the web server asking it to retrieve and transmit the requested web page. SMTP – Simple Mail Transfer Protocol and it is used to send email messages between servers. Email can be sent over the Internet using the SMTP protocol to send messages from one server to another; Messages can then be retrieved with an email client using POP or IMAP protocols. Typically, SMTP is used to send messages from an email client to an email server, which is why the client must specify both the POP or IMAP server and the SMTP server when configuring the mail application. messaging. The Network Interaction Layer The network interaction layer is the lowest layer. of the TCP/IP model and could also be called link layer. The network interaction layer combines the physical layer and data link functions into a single layer. It also includes physical frame network functions such as modulation line coding and bit synchronization, frame synchronization and error detection, and LLC and MAC sublayer functions. For this layer, the most common protocols include ARP (Address Resolution Protocol), NDP (Neighbor Discovery Protocol), IEEE 802.3, and IEEE 802.11. The Internet Layer The Internet layer is the layer that contains the packet construct that will be transmitted. This takes the form of an IP protocol which describes the packet containing a source IP address, a destination IP address and the actual data to be transmitted. Functions include: traffic routing, traffic control, fragmentation and logical addressing. For the Internet layer, the most common protocols are IP, ICMP and IGMP. The Transport Layer The transport layer is the next layer and it is responsible for message segmentation, acknowledgment, traffic control, session multiplexing, error detection and correction, and reordering messages. Common protocols include.
