TCP/IP - SDLC - Research Paper Example

For communication to exist between these protocols, the rate of transmission and model of the transmission defined. Implementation of protocols takes place through either software or hardware (Naugle,2009). Transmission Control Protocol and Internet Protocol (TCP/IP) allow communication between computers in a network and the internet. What TCP/IP does is setting rules for how data is exchanged in the internet and how computers should access the internet. The TCP/IP uses several protocols for this communication to happen with the Internet protocol and the Transmission control protocol being the main ones.

Other protocols that are involved in this process and these include the Transmission Control Protocol, which allows communication between applications (Guruge, 2012). The other is the Internet protocol that allows unified communication between computers. The Dynamic Host Configuration protocol allows for dynamic addressing while the Internet Control Message Protocol handles any errors that may arise from the communication. Protocols are based on the seven layers of OSI (Morse,2010). The Transmission protocol takes the fourth layer of OSI, which is transport while the Internet Protocol takes the third layer, which is networking. . Most of the internet users use TCP/IP where a web browser communicates with a web server.

TCP/IP means the Internet Protocol and the Transmission Control Protocol working together whereby the TCP takes care of communications between applications such as the browser and the intranet or Ethernet. IP on the other hand concerns the communication between computers or over the network (Morse,2010). The Internet Packet sends the packet from the computer, and it then goes to the IP router. The IP router sends the packet to the desired location. IP is therefore responsible for facilitating this communication.

System Development Lifecycle (SDLC) System development lifecycle consists of the stages that are involved in the development of information systems. The stages begin with the conducting of the feasibility tests until the whole project is completed. There are various models used in the systems development lifecycle and these models include the waterfall method, the spiral model, the build and fix, rapid prototyping and even the incremental method. These methods however follow a standard procedure that involves conducting feasibility test to study the viability of the project; requirement definition stage involves the definition of the goals and the needs of the end user.

The other is the system design where description of the desired features of the project takes place. Implementation of the project takes place next. The testing of the project to check for errors, bugs and compatibility issues are handled in this stage (Howard & Lipsner, 2008). Installation of the project where it is put into real work. The final stage involves maintenance, which takes place over time. During the development process, the security of the project needs
