π TCP/IP is the most widely used protocol today for communication in networks.
π TCP/IP provides end-to-end connectivity and specifies how data should be formatted, addressed, transmitted, and received.
𧱠The TCP/IP protocol stack is composed of four (or five) layers, including the network access layer and the internet layer.
π The TCP/IP protocol establishes a set of rules for communication between computers.
π Data travels through different layers of protocols, with each layer adding an information header.
π The data packet changes its appearance at each layer, with different names and headers.
πΆ The first layer, known as the network access layer, receives data from the higher layer and transmits it through physical media.
π The internet layer handles the communication between machines and utilizes routing algorithms to determine if data should be processed locally or transmitted.
π Protocols such as IP (Internet Protocol) are used in this layer to verify the validity of data and handle its transmission.
π‘ TCP/IP is a bidirectional communication protocol used to transmit data through connected networks.
π The TCP/IP transport layer is responsible for segmenting and reassembling data between communication streams.
π The transport layer ensures secure handling of data segments and tracks individual communication between applications.
π The TCP/IP protocol provides services for segmenting and encapsulating data.
βοΈ The transport layer handles the communication and reliable delivery of data.
π TCP ensures data integrity through acknowledgment and error correction.
π‘ The TCP/IP protocol consists of multiple layers, including the application layer.
π‘ The application layer provides the interface between applications and the underlying network.
π‘ The application layer performs functions such as file transfer, command syntax, data encoding, data compression, and encryption.
TCP/IP is a protocol that encompasses various application layer protocols.
Some of the application layer protocols in TCP/IP include DNS, HTTP, SMTP, and FTP.
These protocols are used for translating domain names, transferring web files, sending emails, and interactive file transfers.
