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

FTP uses the Internet's TCP/IP protocols to allow data transfer. FTP is commonly used to download a file from a server over the Internet or to upload a file to the server. The HTTP-HyperText Transfer protocol allows users of the World Wide Web to exchange information found on web pages. This protocol dictates 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 the URL into their browser, it sends an HTTP command to the web server directing it to retrieve and transmit the requested web page.SMTP- Simple Mail Transfer Protocol and is used to send email messages between server. An email message can be sent over the Internet using the SMTP protocol to send messages from one server to another; the messages can then be retrieved with an email client using the POP or IMAP protocol. Generally, SMTP is used to send messages from a mail client to a mail server, which is why the client must specify both the POP or IMAP server and the SMTP server when configuring the email application. The Network Interaction Layer The network interaction layer is the lowest layer of the TCP/IP model and could also be called the link layer. The network interaction layer combines both the function of the physical layer and the data link layer into a single layer. It also includes physical frame network functions such as modulation line coding and bit synchronization, frame synchronization, and error detection, as well as LLC and MAC sublayer functions. For this layer, the most common protocols include Address Resolution Protocol (ARP), Neighbor Discovery Protocol (NDP), IEEE 802.3, and IEEE 802.11. The Internet Layer The Internet layer is the layer that contains the construct of the packet that will be transmitted. This takes the form of the IP protocol which describes the packet containing the source of the IP address, the destination of the IP address and the actual data to be delivered. 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 is responsible for message segmentation, recognition, traffic control, session multiplexing, error detection and correction, and message reordering. Common protocols include Transport Control Protocol (TCP) and User Datagram Protocol (UDP). The application layer Hold.
