A?Network+ Chap TCPIP Fundamentals

TCP/IP stands for Transmission Control Protocol/Internet Protocol, and it is a set of protocols that allows computers to communicate with each other over networks, such as the internet. It provides a reliable and standardized method of data transmission, addressing, and routing.

TCP/IP offers several key features, including addressability, reliability, fragmentation and reassembly, flow control, error detection and correction, and multiplexing. These features ensure efficient and secure data transmission across networks.

An IP address is a unique numerical label assigned to each device connected to a network that uses the TCP/IP protocol suite. It serves two main purposes: network identification and host identification. IP addresses can be classified into IPv4 and IPv6 formats.

TCP (Transmission Control Protocol) is responsible for establishing a reliable, connection-oriented communication between devices over an IP network. It ensures that data packets are delivered in the correct order, without errors or duplications.

IP (Internet Protocol) is responsible for addressing and routing data packets over an interconnected network. It ensures that packets are sent from a source device to a destination device using the most efficient path available.

TCP/IP offers various advantages, such as scalability, interoperability, platform independence, robustness, and widespread adoption. It is the foundation of the internet and allows for seamless communication between different devices and networks.

TCP (Transmission Control Protocol) is a connection-oriented protocol that guarantees message delivery, order, and error checking. UDP (User Datagram Protocol) is a connectionless protocol that does not guarantee reliable delivery or message order, making it suitable for applications that prioritize speed over reliability.

Ports in TCP/IP are used to provide specific services to network applications. They help differentiate between multiple processes running on a device by assigning unique port numbers. This enables effective communication between client and server applications.

Yes, each device connected to a TCP/IP network must have a unique IP address. This uniqueness allows the devices to be identified, addressed, and communicated with correctly within the network.

TCP/IP uses various error detection and correction mechanisms, such as checksums and acknowledgment packets, to ensure data integrity during transmission. In case of errors, TCP handles retransmission of lost or corrupted packets to maintain reliable data transfer.
