TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, is a set of communication protocols used for the interconnection of network devices on the internet. It serves as the foundational framework for the internet and many other networks.
**Purpose of TCP/IP:**
1. **Communication**: The primary purpose of TCP/IP is to enable data transfer between devices across diverse networks. It allows different types of computers and networks to communicate with each other.
2. **Standardization**: TCP/IP provides a standardized way to send and receive data, ensuring that devices from different manufacturers can work together seamlessly.
3. **Data Transmission**: It manages the packaging, addressing, transmission, routing, and delivery of data packets over the network. This ensures that data reaches its intended destination accurately and efficiently.
4. **Reliability and Error Handling**: The Transmission Control Protocol (TCP) part of TCP/IP ensures reliable communication. It establishes a connection, manages data transmission, and identifies transmission errors, allowing for data retransmission if necessary.
5. **Addressing**: The Internet Protocol (IP) handles addressing by assigning unique IP addresses to devices on a network. This is crucial for identifying devices and ensuring data is sent to the correct location.
Overall, TCP/IP is essential for enabling internet functionality, allowing everything from web browsing to email communication to occur. It facilitates the global exchange of information, making it one of the most significant protocols in modern networking.

The TCP/IP system’s purpose is based on how networks operate. IP stands for Internet Protocol. TCP stands for Transmission Control Protocol. The IP is where each website gets a specific address. The address given to a website is a specific set of numbers which the system uses to be able to find that particular website. When the addresses are entered into the system, the system processes the number as a binary number which is a set of numbers which is based on the 32 bit numbers system. This system uses the IP addresses to easily access websites in the system. The IP system can be used with either the IPv4 system which is version 4, the original system or there is a newer version which is IPv6 or version 6. The TCP side of the TCP/IP system looks at the process of getting to the system, or the transportation. (Mile 2).

The overview of the TCP/IP system is concise and informative. It effectively breaks down the roles of both the Internet Protocol (IP) and Transmission Control Protocol (TCP), explaining their significance in network communication.
Your explanation of how IP addresses function within a binary system provides clarity on how the network locates specific websites. It’s also helpful that you mentioned the difference between IPv4 and IPv6, highlighting the evolution of internet addressing as more devices connect to the web.

IP addresses like 192.168.100.1 are in a human-readable format, while a computer interprets the same address as a 32-bit binary number, in this case 11000000.10101000.01100100.00000001. The dots matter because the address is divided into four 8-bit bytes, or octets, each ranging from 0 to 255. 8-bit values are common in computing, and IP addressing is a great example of why it’s useful for technicians to understand how decimal values match up with binary octets. In TCP/IP, several transport layer protocols exist, each suited for different types of data and applications. The most common are Transmission Control Protocol and User Datagram Protocol, both essential for even basic networks. TCP is connection-oriented, reliable, supports error correction, flow control, and sequencing. When connecting to a remote host via its IP address, another important number is the port, or socket. Rather than identifying a host, the port number specifies a spot on the Transport layer that marks the end point of the conversation. Every TCP or UDP packet header contains a destination port, usually tied to a specific application on the remote host, and a source port, representing where the local application listens for replies.

Hi Marisa! You did a good job of breaking down what TCP/IP system is. You did a good job of breaking down and explaining what the binary code is, as well as going into depth about some of the aspects of the binary. Another aspect of TCP/IP that you were able to discuss briefly is how different ports are used. Overall, your discussion post had a lot of good points.

The text provides a concise and informative overview of IP addresses and their binary representation, which is crucial for understanding networking basics. It effectively explains the structure of an IP address, detailing how it is divided into four octets and why the dot notation is important.
Moreover, it introduces TCP/IP transport layer protocols, highlighting the significance of both Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). The distinctions between these protocols—specifically TCP’s reliability and connection-oriented nature versus UDP’s simpler, faster approach—are clearly outlined.
The mention of port numbers adds another layer of understanding to network communications, explaining how they are used to identify specific applications on a remote host as well as how they facilitate data exchange on the transport layer.
Overall, the text serves as a solid primer for those looking to grasp the essentials of network addressing and protocols.

Transmission Control Protocol/Internet Protocol, or TCP/IP, is a basic communication model that links computers and other devices over networks, including the internet. It establishes a set of guidelines and standards that govern the packaging, addressing, transmission, routing, and reception of data (De Alencar, 2022) . The foundation of contemporary networking is TCP/IP, which guarantees dependable and effective communication between devices running various operating systems and technologies.
TCP/IP uses a layered architecture to function. Islam et al., (2023) argues that the Internet Protocol (IP) layer is in charge of figuring out the most efficient way for data to move across networks and identifying devices using distinct IP addresses. IP manages addressing and routing, but it cannot ensure that data packets will be delivered reliably.
By ensuring stability, the Transmission Control Protocol (TCP) enhances IP. In
