TCP/IP is an acronym that stands for transmission control protocol/internet protocol. TCP/IP is a set of protocols that make up the bases of how data is transferred on the internet. TCP/IP can be mostly credited to Vinton Cerf and Bob Kahn for its development. TCP/IP was initially financed by the department of defense to connect research networks. (Yasar & Lutkevich, 2024).
More specifically the TCP sends information from one device to another in the form of packets. The packets are broken down into smaller packets in sequential order and sent to the recipient. This in turn allows the recipient to reassemble the packets in sequential order while checking for errors or corrupted files. TCP is used for web browsing, email, and FTP.
After the TCP sends out the data, the IP is responsible for addressing and routing the data to the correct device. IP comes in two main versions IPV4 (32-bit) and IPV6 (128 bit). TCP/IP operates using a four-layer system. The first layer is the link layer. The link layer provides data links between two devices. Next is the internet layer, this layer provides the routing for the data packets. The third layer is the transport layer. The transport layer ensures the packets are delivered efficiently from there the transport layer transmits data from one host to another this includes TCP and UPD. The final layer of the TCP/IP model is the application layer. This layer is what the user uses most. The application layer connects the applications to a network. The application model uses protocols HTTP, FTP, and SSH.
